What type of experiment will we do? Can we chose it?
Ya can we chose the experiment?
Okay class! Today we are working on variables, and we will be doing an experiment
That's a great idea!
Sure, you can chose it. What would you like to do?
Can we bounce a tennis ball on 3 different types of surfaces to see which surface it bounces highest on?
And we can drop the ball outside on the concrete in front of the school last.
First lets drop it on this floor, after that we can drop it in the gym
I'll go get the ball and the meter stick
Variables are so important because they help and guide you through an experiment.
Why are the 3 variables so important?
If you don't already there are 3 variables, control, dependent and independent. Control is something that has to be the same the whole time. Independent is the thing that you change and dependent is the results.
Wow, I didn't know that! Thanks for sharing.
I recorded the ball bouncing as high as 4 feet and 4 inches
wow I didn't see that coming. I thought the ball would bounce much lower than that.
Wow lets see is the ball bounces even higher on the gym floor since its made for basketball.
Okay you can drop the ball.
The ball bounced 5 more inches than in the lab which is 4 feet and 9 inches high
Looks like guess was pretty accurate, the tennis ball does bounce higher on this floor than it does in the science lab
I'm so happy that our experiment is actually coming together!
OMG, this floor is really mean't for bouncing balls.
