Last week, we got to do an exciting experiment, which involved using water balloons. We were all curious to find out and explore what would happen if we dropped our balloon from a different height? How we use force, will it change how it lands onto the ground?
We first tried this on our own by standing on the bench, outside our classroom. What we noticed that from the higher height and using lots of force, the balloon made a big splash. Compared to using less force, the balloon stayed intact, which means didn’t burst and it kept its shape.
Next we got into groups and dropped our water balloons onto the ground. Some dropped their water balloon from a low height. When it hit the ground, there was no splash and it didn’t break. Others dropped their balloon from a higher height. The splash was big and the balloon burst everywhere.
What did we learn?
More force = bigger splash: When we dropped the balloon from a higher height, it had more force when it hit the ground. This made a bigger splash.
Less force = no splash: Dropping the balloon from a lower height meant it had less force, so the balloon stayed intact.
Our thoughts and reflections:
Jireh: “I really liked when the balloon went splash, it was so cool to see the water go everywhere!”
Luisa: “It was so fun watching the balloons go splash onto the ground!”
Marcus: “I know if you put more force on your throw, the balloon will definitely make a big splash?”
It was a lot of fun watching the water balloons splash and burst! We learned a lot about force and how it can affect the outcome of an experiment.
