Hi I’m Kitty Stars😸😺
Today we are talking about….How sound travels!!
me and my class did two experiments on sound.
Here is the first one:
You need:
- tuning fork
- cup
- water
- saran wrap
- string
- stevia or salt (both have the same result)
- Cover the cup with saran wrap and tie with string.
- Add sugar or salt to the top of the saran wrap on top of the cup
- Hit the tuning fork on metal (we used the legs of our desks).
Here is what it looks like!!
Here is the second one:
You need:
- Tuning fork
- Water
- A cup
- Fill the cup almost half way tot the top with water.
- Tap the tuning fork on metal (we used the legs of our desks) and quickly dip it in the water it should vibrate and spit the water!!
Here is what it looks like!!
