Sound experiment

Hello!

Today I’m going to share with you 2 science experiments that I’ve learned about.

Materials for the 2 experiments:

• turning fork
• plastic cup
• plastic wrap
• strings
• sugar

Hypothesis:

I think that the vibration makes a sound.

Conclusion:

The vibration makes a sound when you hit the sugar. I hit my desk with the tuning fork and then put it on top of the sugar and the cup moved.

2nd experiment:

Hypotheses:

I did not know what to expect at all.

conclusion:

When I hit the tuning fork on my desk and put it in the water splatted on my face. When I hit the tuning fork on my desk then put it on the cup moved.
