Cold War Essay 1947 through 1991 was the time period of the Cold War; the Cold War was a result caused by the tension of the after math of what had happened with world war 2 .The tension that was there wasn t just any kind of tension it was military tension between the power of the eastern bloc and the power of the western bloc. The Cold War wasn t only one war but it was decades of littlewars and intimidation. Germany was busy after the war, there where so much tension between the Soviet Union and the western allies because they had feared each other because they had thought a new war could arise. Minister Churchill then decided that he would put what would be an iron curtain across Europe. The Cold War had so many little conflicts within it like the Chinese revolution, the Palestine liberation organisation, and so many more hundreds if you would that happened in the Cold War time. The 1940’s Mao Zedong was a military leader, a soldier, a principle of the Chinese Marxist theorists, and the man who led his nations cultural revolution. There are so many ways that Mao seems to be the perfect man the man who has his life together and he was a very good self promoter. He is what you could say make China s communism a big deal during the Cold War. The Chinese revolution was placed around 4 years after the war and you could say that Mao had a big impact in that. Being that he did lead the revolution, he was the man who kind of impacted a part ofShow MoreRelatedThe Cold War And The Soviet War845 Words   |  4 PagesThe reason the Cold War was called the Cold War is because there were no physical battles with weapons, tanks, or even artillery, it was a war between capitalism vs. communism, democracy vs. dictatorship.

The Effects Of Exposure On Persons With Social Anxiety...

Finally, a summary of meta-analytic reports by Rodebaugh, Holaway, Heimberg (2004) had a notable post- treatment effect in persons with social anxiety disorder: with effects ranging from moderate to large. These effects were larger in within-group interventions than in waiting-list interventions, and follow up studies done up to 12 months after treatment showed a retention of these effects. Generally, the use of cognitive restructuring and exposure was shown to have better results than the use of other interventions, and their combinations with cognitive restructuring. However, Rodebaugh reported that this difference was insignificant, with the insignificance being attributed to a small number of existing comparisons. In addition, the use of exposure alone and a combination of exposure and cognitive restructuring yielded similar results. Basing this observation, and on the findings from other interventions, it seems that exposure to stressors yields the best results. However, it is not clear whether such benefits are obtained from within- session exposure or from homework exposure. By conducting an empirical review on previously published findings, the researcher intends to find out whether the currently used methods are effective, and possibly introduce a new concept/ argument to the current existing discussion.

Educational Psychology Questions And Answers Essay Example For Students

Educational Psychology: Questions And Answers Essay After reading an article on Jerry Garcia of the Grateful Dead in a Rolling Stone magazine, these are two examples of questions that I would ask my students on a test (in a multiple-choice format.) These questions are also representative of two different levels of Blooms taxonomy. 1) As a member of the Grateful Dead, what was Jerry Garcias only radio, billboard hit single? a) Throwing Stones b) Touch of Grey c) Built to Last d) Franklins Tower Correct answer: b. Touch of Grey. 2) In chronological order, identify which answer represents the progression of keyboard players (pianists) that Jerry Garcia played with in the Grateful Dead? a) Brent Midland, Pigpen, Vince Wellnick, Keith Godchaux b) Pigpen, Keith Godchaux, Brent Midland, Vince Wellnick c) Keith Godchaux, Brent Midland, Vince Wellnick, Pigpen e) Vince Wellnick, Pigpen, Keith Godchaux, Brent Midland Correct answer: b I feel that these are good examples of multiple-choice questions because they do not include in the answer section choices such as, none of the above, or all of the above. It helps to omit choices like these because these answers do not contribute in measuring students mastery of the subject or in teaching unlearned material. These questions both have discriminatory power, allowing me to see who has mastered the material and who hasnt. The distracters that I selected for these questions are the key ingredients that help me see who has mastered the subject. The distracters are not obvious wrong answers, they are choices that make the students think, which ultimately raises the cognitive level of the test beyond that of just memorization and recall. I believe that my questions are clear and easily understood. They should not make the student unnecessarily use energy in figuring out exactly what the question is asking. Also in an attempt to make the question as clear as possible I avoided the use of jargon and other complicated terms. I only used words that would be common to their vocabulary. I also avoided using negative test words such as, not and never. By doing this I made my questions easier to understand. I also tried not to make the right answer too obvious in comparison to my distracters. The last thing that I did to make these questions better was to avoid redundancy by writing and re-writing the questions. Essay questions are very advantageous because unlike multiple-choice questions they can measure what the students know and have mastered. They allow for students to express, in writing, what they do know about the material for which they are being held accountable. The second advantage of the essay test is that they allow students to explain why the material is important to them (this is internalization of information.) Essay questions promote higher levels of thinking and they also allow the students to tap into their creative energies. Essay questions do have their disadvantages like teacher grading bias issues. It is much harder to grade a free-flow of thought, expressed on paper then it is to grade a scantron test. The essay questions have to be thought out so your students dont go astray from what is really being asked. In the 90s over seventy percent of tests were in multiple-choice format. The multiple-choice format allows the teacher to cover large amounts of information with less guesswork then that of true/false or fill-in-the-blank testing formats. Multiple-choice questions are a good way to measure a students degree of judgement, while true/false reduce answers to right/wrong decisions. Multiple-choice questions bring out distinctions between what is good, what is best and what is erroneous. Another major advantage in using multiple-choice questions is their ability to discriminate. .u3185b8f713d8c880b9b1139a3c45109e , .u3185b8f713d8c880b9b1139a3c45109e .postImageUrl , .u3185b8f713d8c880b9b1139a3c45109e .centered-text-area { min-height: 80px; position: relative; } .u3185b8f713d8c880b9b1139a3c45109e , .u3185b8f713d8c880b9b1139a3c45109e:hover , .u3185b8f713d8c880b9b1139a3c45109e:visited , .u3185b8f713d8c880b9b1139a3c45109e:active { border:0!important; } .u3185b8f713d8c880b9b1139a3c45109e .clearfix:after { content: ""; display: table; clear: both; } .u3185b8f713d8c880b9b1139a3c45109e { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u3185b8f713d8c880b9b1139a3c45109e:active , .u3185b8f713d8c880b9b1139a3c45109e:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u3185b8f713d8c880b9b1139a3c45109e .centered-text-area { width: 100%; position: relative ; } .u3185b8f713d8c880b9b1139a3c45109e .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u3185b8f713d8c880b9b1139a3c45109e .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u3185b8f713d8c880b9b1139a3c45109e .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u3185b8f713d8c880b9b1139a3c45109e:hover .ctaButton { background-color: #34495E!important; } .u3185b8f713d8c880b9b1139a3c45109e .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u3185b8f713d8c880b9b1139a3c45109e .u3185b8f713d8c880b9b1139a3c45109e-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u3185b8f713d8c880b9b1139a3c45109e:after { content: ""; display: block; clear: both; } READ: Essay about The Achievement Of The National Honor Society Essay Multiple choice questions give you the ability to tell you which students have mastered the material and which have not. This ability is also known as discriminatory power. Some teachers prefer multiple-choice tests because they think that the objective quality in the test removes the potential for grading bias. Some teachers will also favor multiple-choice tests because they think that students will be less likely to contest their grade. One more obvious but note-worthy advantage to multiple-choice testing is that they are very easily and quickly graded. Educational psychologists argue that one of the major limitations of multiple-choice testing is that they test students on .

Crystal Violet Formal Lab free essay sample

Upon completion of the experiment it was seen that the rate of reaction of crystal violet turned out to be 1 which meant the reaction was first order with respect to crystal violet. This was deduced upon plotting the graph of ln Absorbance versus time of crystal violet and by drawing the line of best fit, which showed that the slope graph was 1 which is the rate of reaction. This whole experiment was based upon the equation: Rate= k [CV+] [OH-], where k stands for the rate constant. Introduction: Kinetics, which is the study of how fast a reaction takes place or in other words the rate of a reaction, is the main ideology in this experiment. Reaction rates can be measured in a number of ways: by monitoring the amount of product formed, by measuring the loss in mass of reactants, for reactions involving gaseous products measuring the volume of gas produced, by electrolytic conductivity, pH measurement or for colored reactants or products measuring the transmittance by the use of a colorimeter. In this experiment the last method of measurement is used which is colorimetry. Colorimetry is a method of determining the kinetics of a reaction using a spectrometer which observes the amount of light that is absorbed or transmitted through a colored solution. As a reaction proceeds, the reactants either fades away or the product forms the color. By monitoring these changes the amount of product formed or reactant used up with respect to time can be monitored. The amount of light that is absorbed by a colored substance can be measured by calculating percentage absorbance or transmittance. A very helpful device known as colorimeter which is present in almost all equipped labs makes this quite simple to deduce. The machine displays the amount of light that passes through or absorbed by the substance. This instrument is based on the optics law or more commonly known as Beer-Lambert law, which is used in measuring the concentration of a solute in contrast to its absorbance. The colorimeter measures the wavelengths of different solutions as they vary. Distilled water is used as a reference in this experiment as it contains no colored elements and has a value of zero when inserted into the colorimeter. Crystal violet, a purple dye commonly used in inks or printers is reacted with sodium hydroxide, commonly known as caustic soda which is a powerful base. Sodium hydroxide is a colorless solution which when reacted with crystal violet causes it to lose its purple color and form a colorless product. The purpose of this experiment is to determine the order of the reaction with respect to crystal violet by using colorimetry. The amount of crystal violet is kept at a constant during the whole experiment while various amounts of sodium hydroxide, each of varying concentration are used. This method of determining rates is called the isolation method. Amount of reactant used with respect to time or the rate of reaction can be determined by plotting a graph of concentration versus time for the reactant if the reaction is first order. The slope is a measure of how much reactant is used per unit of time. As the concentration of reactant reduces in a chemical reaction, the slope is a negative value, hence by considering the absolute value of the slope, the rate of reaction of that reactant can be found for the reaction. If the reaction was to be of second order, a graph of ln of concentration versus time would produce the rate of reaction by determining the slope like before. It must be noted that only the absolute value of the slope matters in this situation. Third order reactions have somewhat a similar story except they require a plot of 1/concentration versus time to determine rate of reaction. When all three graphs are plotted, the graph with the line of best fit, or the one in which all point seem to be on a straight line is the correct one for the reaction. This is easily drawn using the LoggerPro software. When all three graphs are drawn, the graph with the best fit line and lowest root mean square error, or the lowest deviation from the best fit line, is the graph to be used to determine reaction kinematics. This knowledge is acquired from the equations of the integrated rate laws which are explained in the textbook. The solutions are mixed in small amounts in cuvettes and inserted into the colorimeter, which reads the percentage transmittance during the time period. The colorimeter has an enclosed space for the cuvette to be inserted making sure light from other sources does not interfere with the reaction, hence providing accurate results. The rate of the reaction is determined by using the equation: Rate= k [CV+] [OH-], where k is the rate constant for the reaction. Materials: Solutions of crystal violet and sodium hydroxide were available in the laboratory which were previously prepared of concentrations 2. 00 E-5 and 2. 00 E-2 respectively. Deionized water was used in calibration while cuvettes were used to transfer substances into the colorimeter. Magnetic stirrers along with stir bars were used in mixing the reagents together which were transferred to the beaker via pipettes to ensure accurate results were produced. Methods: Three solutions were made to be put into the cuvttes. The first of them contained 20ml of crystal violet and 20ml of sodium hydroxide. The second had 20ml crystal violet along with 10ml of distilled water and 10ml of sodium hydroxide. The third solution contained 20ml crystal violet with 15ml distilled water and 5ml sodium hydroxide. The reagents were mixed well in beakers, each containing the different solutions and were stirred sufficiently on a magnetic stir plate. The colorimeter was calibrated with distilled water which set a reference value of zero making sure that all succeeding readings would be accurate. A small sample of the first solution was placed in a cuvette which was inserted into the colorimeter. Data collection started immediately and was recorded for 15 min, the whole duration of the cuvette in the colorimeter. The different values of transmittance were recorded and the data was plotted into a graph with the help of LoggerPro software. The same procedure was repeated for the second and third solution and thereby obtaining three different Absorbance versus time graphs for each. Care was taken at every step of this experiment to ensure that errors were minimized to the fullest. The colorimeter was calibrated every time before placing a new cuvette into it to make sure results were accurate. The dye was handled with care as it leaves stain marks on any surface it is spilled on. Goggles were worn throughout the experiment to keep the eyes from risk of exposure. Safety gloves were worn to handle all reagents as one of them, sodium hydroxide, is a strong base and has significant corrosive properties. The graphs obtained from the three solutions were then manipulated using the LoggerPro software which enables he application of various calculus functions to produce different graphs, all of which lead to determination of the order of the reaction. A line of best fit was applied to all three graphs and the slopes (m), absorbance value at 7min (a) and the root mean square error (RMSE) were recorded. The first graph was reopened and a new column of ln Absorbance was made, using this data, another plot of ln Absorbance versus time was created using LoggerPro. This was done again for the second and third solutions. The graph of Absorbance versus time for the first solution was opened again to produce a graph of 1/Absorbance versus time which was saved. All of these were made possible using LoggerPro. All of the graphs produced had a line of best fit through them which made it easy to determine slope and RMSE values for each of them along with absorbance values at 7 minutes, which is the half life of the reaction period or half the time for the data to be collected. All of the data collected from the graphs were tabulated and values were used in determining the reaction rate of the reaction.

Discussion: Table 1 shows the absolute (RMSE /a) values for the first solution. The RMSE values are obtained from the graphs produced from solution 1(graphs 1, 2 and 3). The graph with the least absolute RMSE/a value is the one with the best fit line with the greatest accuracy; hence the graph 2 or the plot of ln Absorbance versus time for solution 1 is the most accurate one as it has an absolute RMSE/a value of 0. 129. Thus it can be deduced from the table that the reaction is first order with respect to crystal violet. Since it is now known that the reaction is first order with respect to crystal violet, the functional relationship for p=1 is: ln Absorbance= [ln Absorbance]0- kpst; This equation is familiar since it is one of the integrated rate law equations as seen previously. First order reactions are determined if the plot of ln Absorbance versus time ha ve a line of best fit which is accurate. Thus the equation above shows that the best fit line from the plot would equal to –kps. Therefore the kps values would be equal to negative of the slopes of ln Absorbance versus time graphs for all three solutions which is depicted in Table 2. To determine the order of reaction with respect to [OH-] some more calculations are required and more graphs are required to be plotted. The kps values obtained from Table 2 along with the [OH-]0 values aid in the plotting of another kps versus [OH-]0 graph. The graph that is obtained is shown in Figure 5. To double check the accuracy of the graph, a second graph of ln kps versus ln [OH-]0 is plotted which would be the graph if the reaction was to be of order 1 with respect to [OH-] which is depicted in Figure 6. When the two graphs are compared to each other and their slopes and RMSE values compared from the data collected in Table 3, it is seen that the reaction is actually in fact order 1. 5 which when rounded off to the nearest integer would be equal to 1. q= slope of plot of ln kps versus ln [OH-]0= 1. 581 as seen from Figure 6. The RMSE value is also a very low value which means that this value would be very accurate and hence the reaction would be first order with respect to sodium hydroxide. The discrepancy in the final value of q can be accounted for by transfer losses, when the reagents were being transferred from the pipette to the beaker; some of it remains in the pipette and causes the concentration to be a little lower than actually reported. It should also be noted that the same cuvette was not used throughout the experiment. Different cuvettes are made from different plastics from varying compositions which mean they have different permeability which doesn’t allow the same wavelengths of light to pass through all of them, thus the colorimeter reads differently which causes errors. The reaction starts off with a purple color as crystal violet is a purple solution and sodium hydroxide is colorless. As time elapses, the violet color starts to fade away and the solution becomes colorless as their product is a colorless aqueous solution. Conclusion: Thus the above experiment concludes that the reaction was first order with respect to crystal violet and also first order with respect to sodium hydroxide. The overall reaction order was 2 with respect to crystal violet and sodium hydroxide. The overall of the rate law for the reaction would be: Rate: k [CV+] [OH-]. To ensure results are more accurate in the future, a single cuvette should be used when carrying out the whole experiment and all of the reagents must be transferred efficiently without loses to and from the beaker to ensure 100% efficiency along with using proper safety equipment while handling chemicals.

When my family decided to move in America I discover the importance of education. I was studying on tenth grade, and my life has been just simply like a student. Let me talk about my education. I was studying in government schools like in America that I don’t have to pay until I graduate from high school. My school provides all subject like I learned English, math, science, and social study, but I never speak English like here. Back in my country, I was not serious about taking my education and I never thought what my future will be, but now I realize education is most important in my life. As soon as I arrived in America I notice that I have to get a good education to help my family and myself. However, I starte. .g up mood my mother prompt me to move ahead and she give an example of several people who came from another country and became famous like Albert Einstein who was born in Garman and other more. After I heard those words from her I felt that I can do it my best I can. Because of those famous people who was coming from another country encourage me to do something and never give up in any field in my life. Now, looking back over my past as a result of moving to America from my country Nepal I felt that I will have a better education which I could not get in my country Nepal. I will work hard and do my best to work on my career and fulfill my dream that comes true. Also I commitment by myself to never giving up to do the best thing in my life. I will always continue to search for new paths.

A KELLOGG LASTING VALUE ESSENTIAL - A Tester Said No

A KELLOGG LASTING VALUE ESSENTIAL - A Tester Said NoThe Kellogg Lasting Value Essay is an online test designed to measure a student's ability to produce essays that are at least partially original. Despite this, I am certain that I cannot give you anything substantial about the test or its results without first giving some background information about its development.My findings on the Kellogg Lasting Value Essay were based on my own personal research, as well as observations of other students. I found that this test was developed by Dale Kellogg and Kenneth Kellogg.In the year 1960, Mr. Kellogg had introduced what he called the 'Kellogg/Denise Blumberg Reading Comprehension Test' (sometimes known as the 'Kellogg Test'). This test was a more difficult version of the SAT (Scholastic Aptitude Test) used in college admissions.I studied the transcript of this test and found it to be quite different from the format and vocabulary used in today's tests. It also seemed to have a lot of repe tition in the vocabulary and structure of the tests used in college admissions. The person who wrote the original test was a woman named Karen Blumberg.That made me think that Ms. Blumberg was the one who created the test. That led me to a long search for the original tests, which turned up nothing.Another point that I made to myself in that search was that it would be easier to find the original test rather than take a test which uses words and structure similar to the one that we know today. The way the test is structured, there is a lot of repetition in the vocabulary and structure. I felt that my effort to find the original will be worth the time spent searching for it.So, while I was not able to find any of the original tests, I did find a sample essay sample. This is a great tool if you need to know how to do a test like this.It gives you a good idea of what it is like to write a test like this, but do not rely on it to tell you how to do a test like this. If you want to write a test like this, you should consult a professor.

Independent and Dependent Variables Which Is Which

Independent and Dependent Variables Which Is Which SAT / ACT Prep Online Guides and Tips Independent and dependent variables areimportant for both math and science. If you don't understand what these two variables are and how they differ, you'll struggle to analyze an experiment or plot equations. Fortunately, we make learning these concepts easy! In this guide, webreak down what independent and dependent variables are, give examples of the variables in actual experiments, explain how to properly graph them, provide a quiz to test your skills, and discuss the one other important variable you need to know. What Is an Independent Variable? What Is a Dependent Variable? A variable is something you’re trying to measure. It can be practically anything, such as objects, amounts of time, feelings, events, or ideas. If you’re studying how people feel about different television shows, the variables in that experiment are television shows and feelings. If you’re studying how different types of fertilizer affect how tall plants grow, the variables are type of fertilizer and plant height. There are two key variables in every experiment: the independent variable and the dependent variable. Independent variable:What the scientist changes or what changes on its own. Dependent variable:What is being studied/measured. The independent variable (sometimes known as the manipulated variable) is the variable whose change isn’t affected by any other variable in the experiment. Either the scientist has to change the independent variable herself or it changes on its own; nothing else in the experiment affects or changes it. Two examples of common independent variables are age and time. There’s nothing you or anything else can do to speed up or slow down time or increase or decrease age. They’re independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It’s what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages. The dependent variable (height) depends on the independent variable (age). An easy way to think of independent and dependent variables is, when you’re conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect. It can be a lot easier to understand the differences between these two variables with examples, so let’s look at some sample experiments below. Examples of Independent and Dependent Variables in Experiments Below are overviews of three experiments, each with their independent and dependent variables identified. Experiment 1: You want to figure out which brand of microwave popcorn pops the most kernels so you can get the most value for your money. You test different brands of popcorn to see which bag pops the most popcorn kernels. Independent Variable: Brand of popcorn bag (It’s the independent variable because you are actually deciding the popcorn bag brands) Dependent Variable: Number of kernels popped (This is the dependent variable because it's what you measure for each popcorn brand) Experiment 2: You want to see which type of fertilizer helps plants grow fastest, so you add a different brand of fertilizer to each plant and see how tall they grow. Independent Variable: Type of fertilizer given to the plant Dependent Variable: Plant height Experiment 3: You’re interested in how rising sea temperatures impact algae life, so you design an experiment that measures the number of algae in a sample of water taken from a specific ocean site under varying temperatures. Independent Variable: Ocean temperature Dependent Variable: The number of algae in the sample For each of the independent variables above, it’s clear that they can’t be changed by other variables in the experiment. You have to be the one to change the popcorn and fertilizer brands in Experiments 1 and 2, and the ocean temperature in Experiment 3 cannot be significantly changed by other factors. Changes to each of these independent variables cause the dependent variables to change in the experiments. Where Do You Put Independent and Dependent Variables on Graphs? Independent and dependent variables always go on the same places in a graph. This makes it easy for you to quickly see which variable is independent and which is dependent when looking at a graph or chart. The independent variable always goes on the x-axis, or the horizontal axis. The dependent variable goes on the y-axis, or vertical axis. Here’s an example: As you can see, this is a graph showing how the number of hours a student studies affects the score she got on an exam. From the graph, it looks like studying up to six hours helped her raise her score, but as she studied more than that her score dropped slightly. The amount of time studied is the independent variable, because it’s what she changed, so it’s on the x-axis.The score she got on the exam is the dependent variable, because it’s what changed as a result of the independent variable, and it’s on the y-axis. It’s common to put the units in parentheses next to the axis titles, which this graph does. There are different ways to title a graph, but a common way is â€Å"[Independent Variable] vs. [Dependent Variable]† like this graph. Using a standard title like that also makes it easy for others to see what your independent and dependent variables are. Are There Other Important Variables to Know? Independent and dependent variables are the two most important variables to know and understand when conducting or studying an experiment, but there is one other type of variable that you should be aware of: constant variables. Constant variables (also known as â€Å"constants†) are simple to understand: they’re what stay the same during the experiment. Most experiments usually only have one independent variable and one dependent variable, but they will all have multiple constant variables. For example, in Experiment 2 above, some of the constant variables would be the type of plant being grown, the amount of fertilizer each plant is given, the amount of water each plant is given, when each plant is given fertilizer and water, the amount of sunlight the plants receive, the size of the container each plant is grown in, and more. The scientist is changing the type of fertilizer each plant gets which in turn changes how much each plant grows, but every other part of the experiment stays the same. In experiments, you have to test one independent variable at a time in order to accurately understand how it impacts the dependent variable. Constant variables are important because they ensure that the dependent variable is changing because, and only because, of the independent variable so you can accurately measure the relationship between the dependent and independent variables. If you didn’t have any constant variables, you wouldn’t be able to tell if the independent variable was what was really affecting the dependent variable. For example, in the example above, if there were no constants and you used different amounts of water, different types of plants, different amounts of fertilizer and put the plants in windows that got different amounts of sun, you wouldn’t be able to say how fertilizer type affected plant growth because there would be so many other factors potentially affecting how the plants grew. 3 Experiments to Help You Understand Independent and Dependent Variables If you're still having a hard time understanding the relationship between independent and dependent variable, it might help to see them in action. Here are three experiments you can try at home. Experiment 1: Plant Growth Rates One simple way to explore independent and dependent variables is to construct a biology experiment with seeds. Try growing some sunflowers and see how different factors affect their growth. For example, say you have ten sunflower seedlings, and you decide to give each a different amount of water each day to see if that affects their growth.The independent variable here would be the amount of water you give the plants, and the dependent variable is how tall the sunflowers grow. Experiment 2: Chemical Reactions Explore a wide range of chemical reactions with this chemistry kit. It includes 100+ ideas for experiments- pick one that interests you andanalyze what the different variables are in the experiment! Experiment 3: Simple Machines Build and test a range of simple and complex machines with this K'nex kit. How does increasing a vehicle's mass affect its velocity? Can you lift more with a fixed or movable pulley? Remember, the independent variable is what you control/change, and the dependent variable is what changes because of that. Quiz: Test Your Variable Knowledge Can you identify the independent and dependent variables for each of the four scenarios below? The answers are at the bottom of the guide for you to check your work. Scenario 1:You buy your dog multiple brands of food to see which one is her favorite. Scenario 2:Your friends invite you to a party, and you decide to attend, but you're worried that staying out too long will affecthow well you do on your geometry test tomorrow morning. Scenario 3:Your dentist appointment will take 30 minutes from start to finish, but that doesn't include waiting in the lounge before you're called in. The total amount of time you spend in the dentist's office is the amount of time you wait before your appointment, plus the 30 minutes of the actual appointment Scenario 4:You regularly babysit your little cousin who always throws a tantrum when he's asked to eat his vegetables. Over the course of the week, you ask him to eat vegetables four times. Summary: Independent vs Dependent Variable Knowing the independent variable definition and dependent variable definition is key to understanding how experiments work. The independent variable is what you change, and the dependent variable is what changes as a result of that. You can also think of the independent variable as the cause and the dependent variable as the effect. When graphing these variables, the independent variable should go on the x-axis (the horizontal axis), and the dependent variable goes on the y-axis (vertical axis). Constant variables are also important to understand. They are what stay the same throughout the experiment so you can accurately measure the impact of the independent variable on the dependent variable. What's Next?
