A student is trying to find out if sound travels better through water or through a piece of wood. What should they keep the same in this experiment?
The item making the sound, the volume of the sound, the measurement of how far the sound travels.

What happens to the particles of a sound wave in a compression?
The particles are pressed closer together.

If a sound wave is vibrating back and forth, what type of energy does it have when the particles are moving?
Mechanical energy

Would sound travel better through an open field or a rock wall?
A rock wall

Ms. Silva's 5th-grade class is investigating pitch (how high or low a sound is). They decide to build simple guitars using a wooden box and rubber bands. They want to find out: Does the thickness of the rubber band affect the pitch of the sound it makes? The students gather three small boxes, three different rubber bands (small, medium, large), a centimeter ruler, and their notebook. They stretch the thin rubber band around the first box, the medium band around the second box, and the thick band around the third box. They pluck each rubber band with the same amount of force and record the pitch they hear. What is the independent variable?
The size of the rubber band
