Text z Príbehu
- The wood floors in the basketball court were awesome. The red ball bounced 2m and the tennis ball bounced 1.8m. Lets try this out on the street surface and see if anything changes.
- Great Idea Zac. I think they will bounce even higher this time.
- That was such a fun experiment Eric. It was really cool to see how changing the ground can affect the bounce of the balls. Thank you for including me.
- That was great. The balls bounced so much higher on the pavement. The red one went 5m high and the tennis ball went 4m.
- why are variables so important to have for science experiments?
- The independent variable was the type of floor surface. The dependent variable is the height the balls bounced. The control variables were the same amount of force to drop the ball, same types of balls, and the same height we dropped them from.
- We have variables so we can observe what we need to change or manipulate in an experiment to get the accurate results.
- This was great, Now we have to give an example of each type of variables from the experiment
