Sound and Mediums Experiment

YOUR PREDICTION: (Which will be best, solid, liquid, or gas?) Gas will be the best medium.

Loudness test: Drop a marble in the containers and circle a number indicating the loudness.

Solid - 1 2 3 4 5 6 78 9 10

Liquid- 1 2 3 4 5 6 78 9 10

Gas- Test how well air carries sound What did you hear? What did they say?

1) hmm my aim is eel hello my name is Sheila. 2) how are you how are you 3) dude you ear me did you hear me

How good was gas? 1 2 3 4 5 6 7

8 9

YOUR VERDICT: Circle the winning medium for carrying sound? SOLID LIQUID GAS

Why do you think it was the best? Maybe solid won because solid is hard. Sound needs to hit a hard medium so

it can be heard, not a soft medium like water or gas.

GAS:

Students construct a telephone from paper cups and string.

Students gage accuracy of communication.

What is sound?Sound is a type of energy made by vibrations. When anyobject vibrates, it causes movement in the air particles.These particles bump into other particles nearbyand they vibrate, too. This movement, called sound waves, keeps going until the particles run out of energy. Ifyour ear is within range of the vibrations, you hear thesound.
