Explain how one of the many labs we did demonstrated pitch.
What is the ruler lab - the less hung over table, the higher the pitch, the bottle lab - the more water, the lower the pitch, the slide whistle, the more you pushed in, the higher pitch, the tuning forks - hitting metal objects causes higher pitch compared to wood, dull objects.

What is less vibrations?
300
Describe two ways an object must be for it to have a lower pitch?

What is wood, metal, and glass? Solids cause sound to travel the fastest.

Describe for me two ways you can make an object have a higher pitch.
What is Shorter, thinner, and smaller object?

How do the molecules change in the states of matter such as solid, liquids, and gases? Explain all three for credit.
What is in a gas, the molecules move freely, in a liquid, the molecules pass by each other, and in a solid, the molecules bump into each other (more collisions occur).

What is the microphone, megaphone, hearing aids, and speakers?

Describe a room that will cause sound to reflect in it.
What is a room with all concrete and no objects, a room with wood floors, a room without drapes and a couch to absorb the sound?
