bouncing balls experiment

1. Which of the bouncy balls are going to bounce the highest
2. We described each ball like we named them, what they are made out of, what they were made out of and other
3. Then we made a hypothesis that is that we think the  tennis ball will bounce the highest on all the surfaces ans the baseball would bounce the lest
4. First we did in on the carpet and and we recorded how high they went and we did it three times and average them. Then we did it on a desk and did the same as on the carpet. By this we changed the variable by changing the location. We used a ruler to measure the heights, a notebook to keep track and the balls to do the experiment

What is a Variable? (read on and you will find out)

         A "variable" is a word for a quantity or condition that can change. Variables can be continuous or they can be discrete. Continuous variables can have many values . For example, time is continuous and can have many values. Plant growth, amount of sunlight or amount of water flowing are all continuous variables. Discrete variables are ones that have a few, distinct values. Something can be either on or off, present or absent, or have only several countable possibilities. A kitchen light can be on or off or a person may have blue, brown, green or hazel eyes.
Independent Variable
       An independent variable is a variable that you can control. One way to explain it to a child is that it is the variable that the child can change during the experiment. For example, in an experiment on the effect of light on plant growth, the child can control how much light a plant receives. He can put one plant near a window and another plant in a dark closet.
Dependent Variable
        A dependent variable is the variable that you observe and measure. You have no control over the dependent variable; you want to observe what happens to the dependent variable when you change the independent variable. For example, if the child is testing the effects of light on plant growth, how much the plant grows after some period of time would be the dependent variable. The child can measure how much the plant in the closet grows relative to how much the plant near the window grows.

5. We did charts and graphs 
This is the desk and carpet of all of there average 
 
f

 6. Then we said  that the lighter balls bounced high expert the green one because of its shape.

 7. Then we made our conclusion that is half right because the tennis ball went the highest on the carpet but it did not go the highest on the desk. The bouncy ball and the tennis ball went the tallest. That shows that an independent  variable can change your experiment
