Science Energy Review

What is an insulator?

• something that keeps things cold

• An electrical storm

• something that prevents something else from flowing through it

• a reading book

What is frequency?

• The quantity of sound waves

• The comparison of sound waves

• The high pitch of a voice

• A flat line of sound waves

What happens to your body if you jump into a freezing cold lake?

• The temperature of the water would seep into you and make you cold

• Your body heat would seep into the cold water making you cold

• Your body would stay the same temperature

• The heat energy from the water would raise your body temperature
