Question: (What question were you trying to investigate?)

- If you fill a food container ¼ full with marbles, another ¼ full with beans and a third ¼ full with rice and shake each one, which will produce the most sound?


Question: (What question were you trying to investigate?)

- When you ring a bell in different amounts of water, which amount of water will allow the sound the vibrate the water the most?
Hypothesis: (What did you think was going to happen?)

- We think that the marbles will make more sound because of their shape, size and hardness.


Hypothesis: (What did you think was going to happen?)

- The more water, the less sound will be there so the vibration will be small in lots of water.
Method: (How did you test your question?)

- We will fill each container about ¼ full with it's assigned material (beans, marbles, rice) and shake the container and measure the amount of sound each makes.


Method: (How did you test your question?)

-1. Take the plastic container and fill it up so that the water covers the whole bell.( The water should be above the bell slightly.)
2. Next, take the bell and place it in the container of water. Then add two more cups of water.
3. Then, ring the bell with the stick underwater.
4. Did the water vibrate? Can you hear the bell?
5. After that, take the plastic boat and place it on top of the water.
6. Then, ring the bell again.
7.Now after you ring the bell look at the boat to see how much it is moving. If the boat is moving a lot that means that the water has a lot of vibration. If it barely move that means the water is barely moving.
8.How much did the boat move? Please write your answers on the worksheet.
9. Repeat steps 1-8, but with different amount of water in the container
(then add four then six more cups)
make sure you do it one at a time.
And remember to empty the container before filling it up with the next amount of water.
10. Have fun!!
Materials:

- Plastic containers: plastic food containers with lids.
Glue or tape to seal the top of the containers (if necessary)
Fillings: uncooked beans, rice, marbles.

Sound recorder or other device that will measure sound with a meter. (iPhone, iPod touch, other recording devices can work.)
