Sarah Spivey (via KSAT San Antonio)
Hello parents, teachers and students! If you’re looking for a fun way to make invisible sound *visible* check out these cool activities!
Be sure to check out GMSA@9 on Wednesdays, when Meteorologist Sarah Spivey demonstrates and explains the science behind it.
HERE’S WHAT YOU’LL NEED
- 2 containers
- Water
- Plastic wrap
- Rubber band
- Sprinkles
- Tray
- Large spoon
- Tuning fork (optional)
DO THE ACTIVITY
- STEP 1: Fill one container with water.
- STEP 2: Stretch cling wrap across the other container and make sure it’s tight by using a rubber band — like a drum!
- STEP 3: Place sprinkles on top of the cling wrap.
- STEP 4: Make noise by beating the tray with the spoon. Do this close to the container with sprinkles on top. You should see the sprinkles jump. You can also place the vibrating tuning fork on the container, and you should see something similar.
- STEP 5: Try to make the water move in the other container! You can do this by striking the tuning fork and placing it in the water for dramatic effects!
