Height Impact
Background Research:
We know that the higher you drop an object the item will make an impact to the sand. I know this because when an egg slips from your hand, it will likely crack after it lands on the floor. Just like phones. When it's lower than you knees it's possible that it won't make a mark on your screen. But the higher you drop your phone, the chances are, it will crack/break.
Conclusion
Impact Depth Per Height of Drop
After doing the experiments in five trails, we can claim that our hypothesis was partly true. The table that you saw previously shows that when you increase the height, the object will most likely make a greater impact to the sand. On the other hand, while we increase the height of dropping the ping pong ball, its impact had stayed the same with 0.1 cm. While the balls had made a difference with the impact after letting go of the ball.
Materials:
12 inch ruler
1 Rectangular pan
1 Tray
1 Ping Pong Ball
Height Impact Video :
Cat litter
Scooper
Happy & Sad Balls
Safety Precautions
- Remove unnecessary stuff from the experiment. (Like backpacks, books water bottles)
- Don't go too close-sand might get in your eyes.
- Don't mess with litter.
- Don't lose the balls (or any materials)
Procedure:
- Get the following materials listed.
- Pour in the kitty litter in the pan about 1.0 centimeter. And make sure the tray is under the pan.
- Make the surface of the sand smooth using a ruler.
- Take the length of the ruler & jab it on the base of the tray, it should measure to 1.0 centimeter. If not add more or less of the kitty litter.
- Take the rule, the 0 cent. should be on the ground of the sand & hold a ball a few inches from the ruler. The ball should be at the height of which is told.
- Drop it and record your results.
- Do it four more times with different heights and different balls.
- After finish with the experiment, use the scooper to scoop up the sand and bring it to the kitty container.
Variables
- Independent variable: Height of the ball.
- Dependent variable: Impact of the sand.
- Control variable: The smoothness of the kitty litter (Sand)
- Constant: Balls used.
Hypothesis:
If we increase the height dropped from the three different balls, then the impact on the sand will increase.
