Science Buddies: "Ask an Expert"

I have posted a question yesterday about this problem that i am having, here is the link to that question :"viewtopic.php?f=26&t=18908&p=63885#p63885"
, Mr.Norman40 has tried to answered my question, but it is not what i'm looking for. The thing that i want from it is an experiment that i could make it so that it could be related to physics motion and forces. I have made up one, but then my teacher rejected it, because he said it is measuring, you're not testing anything. My old experiment was about how does the bounciness of the ball affect the distance how far will it travel. It was a measuring experiment, which you're not testing anything, you're just measuring the distance that the ball will travel. I really need help with a new experiment that i could actually test it, not just measuring the distance. Please i need help ASAP!!!!

The project that the Expert linked for you (https://www.sciencebuddies.org/science- ... g-dynamics) is, in fact, testing something. If you read it carefully, you will see that a test is being conducted. You will be taking measurements to determine how change in the independent variable affects the dependent variable. I would suggest re-reading the project, getting a clear understanding of the variables, and then talking with your teacher. Maybe you didn't fully convey the project?

The objective is on the summary tab: In this experiment you will test if air pressure will affect the dynamics of ball bouncing.

Here are two other projects you might look at:
