Guiding Question: How does a wave travel in various liquids?
Hypothesis: I think that if the liquid has more density the wave will travel slower, and when it has less density then it will go faster.
Materials:
● Plastic pan
● water
● oil
● chocolate milk
● flour and water (mixed)
● modeling clay
● Boll
Procedure:
1. Fill the plastic pan with one of the liquids. If you want to do it first with flour and water you have to mix it up in boll.
2. Get the modeling clay and try to make waves by putting it in the clay but don’t touch the bottom of the pan!!!
3. Look how big is the wave length and how far it goes. If it comes back to the start or not. Record that in the table below.
4. Then do Data Analysis, and conclusion!
Data Table:
| Liquid | Observation | | |
| Oil | a little wave that doesn’t go until the other side of the pan | | |
| Water | a big wave that goes until the other side and comes back | | |
| flour and water mix | a little smaller then the water wave and goes until the middle of the pan | | |
| | | | |
Data Analysis: The oil has the most density so the waves are slower than the water and the water with flour. So that means that the density does effect the wavelength and the frequency.
Conclusion: In conclusion my hypothesis was right. I wrote the density of the liquid does effect the wavelength and it will go slower as I thought.
