Hello, everybody. Today I will show and explain the 3 variables in an experiment where I'm dropping these different coloured balls from different heights to see how high they bounce.
For this experiment our independent variable will be that we have to use the same balls in all the experiments.
Our dependent variable is how high the balls bounce.
And our control variables are how hard we drop the ball, how high we drop the ball from, and that we keep the same balls the same the whole time.
The teacher put on the video and there's a science teacher in it.
Firstly we're going to drop all the balls off this ledge.
He is explaining what the independent variable is for the experiment.
The blue ball bounced 10 meters, the yellow ball bounced 13 metres, and the red ball bounced 7 meters.
He is explaining the control variables.
Thank you for watching my video on the three variables of science.
The teacher is dropping balls off the side of a building.
The teacher is saying how high all the balls bounced.
