Guiding Question
Does the size and weight of an object determine the size of the waves it makes?
Hypothesis
I think that the size/weight of an object does affect the amplitude of the waves produced.
Variables
Does the size and weight of an object determine the size of the waves it makes?
Hypothesis
I think that the size/weight of an object does affect the amplitude of the waves produced.
Variables
- Controlled: Water, pan
- Manipulated: Size and weight of objects dropped in
- Response: Amplitude of waves.
Materials
Water
Pan
1 pound weight
2 pound weight
cork
small metal ball
Procedure
- Fill pan with water.
- First, drop the 1 pound weight in. Record the height of the waves (roughly) in the data table. repeat the process two times. Remove the weight.
- Next, drop the 2 pound weight in, and so on. Record all of your observations in the data table.
