Exploring Sound and Energy

Maria and Sarah made a set of paper cup telephones. First, the girls punched a hole in the bottom of each cup. Then they connected the cups with a very long piece of string, knotted in the bottom of each cup. Maria went down the hall to her bedroom while Sarah stayed in the kitchen. When Maria put the cup to her ear she could hear Sarah talking to her because

• they were not that far from each other.

• sound waves traveled through the string to Maria’s cup.

• sound waves traveled through the air from room to room.

• sound waves bounced off of the walls to reach Maria in the bedroom.

Samantha's 4th grade science class is conducting a STEM experiment building boats. The class was divided into four groups and each group was given a Styrofoam bowl, 6 inches of tape, a straw, and a piece of paper. Each group had to create a boat using only these materials. The group whose boat went the farthest distance would receive an A for the day. Two of the groups used the bowl as the base of the boat and taped the straw into a standing position. They then folded the paper into a triangular shape and taped it to the straw. Why was taping the triangular paper the most important part of the boat?

• The paper makes the boat level so the boat does not tip over.

• The paper is used as an oar to move the boat in a forward motion.

• The paper serves as a sail to catch the wind and cause the boat to move farther.

• The paper serves as an attempt to prevent the boat from taking on water and sinking.

This is a wind turbine. Wind flows over the blades and causes them to turn. The blades are connected to a rod inside the tower. The rod connects to a generator that turns the wind energy into

• air.

• electricity.

• smoke.

• water.

Patricia is learning about sound waves and pitch in science class. He knows that sound waves carry energy produced by a vibrating object and the speed of that vibration controls pitch. Which describes the connection between sound waves and pitch?

• Sound waves that vibrate quickly have a low pitch. 

• Sound waves that vibrate slowly have a high pitch. 

• Sound waves that vibrate quickly have a high pitch. 

• 
  Sound waves that vibrate slowly have no pitch. 

Micheal knows that sound is created by vibrations.  What determines the pitch of the sounds produced by the vibrations?

• The energy of the vibrations. 

• The speed of the vibrations. 

• The material the vibrations travel through. 

• The shape of the vibrating object.
