What happens when you drop a small and light object into the water? What happens when you drop a big and heavy object into the water? What kind of waves will these objects make?
What I am sure of is that light and small objects make small waves that quickly disappear. Bigger and heavier objects make bigger waves that last longer. Because The bigger the object, the bigger the wave and the bigger the wave, the longer it lasts.
What you need for this:
1. plastic pan
2. water
3. heavy and light objects
4. ruler
5. timer
Fill up the plastic pan of water. Next find some light and heavy objects in your house. Drop either the light or heavy object into the water. Pay attention on what waves does the object make. time how long the wave lasts and measure the height quickly.
Here are my observations:
small rock: height 0.1 mm, time: 2 seconds
dragon statue: height 0.5 mm, time: 4 seconds
When I dropped the small rock into the water, it made a small splash. it lasted for only 2 seconds and its height was 0.1 mm. The dragon statue made a big difference. it made a big splash and the wave lasted for 4 seconds and its height was 0.5 mm.
I saw that the relationship was that how did the small rock and dragon statue react when they hit the water. They both made different waves because the small rock is small and the dragon statue is big.
So in conclusion, Objects with different kind of weight and different size make the wave either big or small.
I did have some errors while doing this. When I was dropping the objects into the water, they made the splashes too quickly and I couldn't get the height. Next time I should use a different strategy of how to measure the height of a wave.
I also have one final question. What happens when you drop the small and light object and the big and heavy object at the same time? Would they make the wave bigger or would it just be the same?
