Sound Light Heat Electricity States of Matter
100
In waves

100
Straight line ------->
How does light travel? Draw a picture to show an example.
100
Sun, burning, friction, electricity
Name 4 ways heat is produced.
100
In a circuit (circular closed path)
How does electricity travel?
100
Particles are close together, has its own shape
Describe the properties of a solid
200
Vibrations (moving back and forth quickly)
How is sound produced?
200
She should wear dark colors because the light will be absorbed and changed to heat energy.
What color should Jodi wear in the winter? Why?
200
From a warm object to a cooler object
Describe how heat travels.
200
1 battery, 1 bulb, 1 wire

(Any diagram where each piece is touching each other)
Name the fewest supplies you need to make a circuit. Draw a diagram.
200
When the temperature is below 32 degrees and it can freeze or solidify.
When does a liquid become a solid?
300
slowly.
An object with a low pitch vibrates...
300
The light is reflected (bounces back)

(Any example where the path of light bounces back at the same angle)
What happens to the path of light when looking in a mirror? Draw a picture to show an example.
300
Foam or plastic because they are insulators and will keep the heat in.
Mrs. Franks needs to choose a material that will keep her coffee warm the longest. What should she choose? Why?
300
One pathway, share electricity, bulbs are dim, if one bulb is removed then all of the bulbs will go out
Describe a series circuit focusing on the number of pathways, the brightness of the bulbs and what happens when one bulb is taken out.
300
The water is evaporating and going from a liquid to a gas.
Cameron is boiling water on the stove and notices steam rising. Describe what is happening.
400
make it shorter (length), make it thinner (thickness), make it tighter (tension)t is
Name 3 things that could be done to make the pitch of an instrument higher.
400
Must be shiny, metal and smooth
In order for an object to reflect light, what 3 properties must it have?
400
Fire --> marshmallow --> metal stick --> Mike's hand
Mike is roasting marshmallows by the fire. He used a metal stick and burns his hand. Describe how the heat was transferred.
400
Penny, nail, paper clip or anything metal.

Conductors
Johnny makes an open circuit. Name 3 things he could put in the circuit to close it. What are these objects called?
400
It melted and went from a solid to a liquid because it was warmer than 32 degrees.
Billy left out his ice cream bowl for a few hours on a hot day. Describe what happened.
500
Waves should be the same height, wavelengths farther apart for low pitch and close together for high pitch
Draw 2 sound waves with the same volume but different pitches.
500
The light is being refracted (bending) when it enters the water. is
Dana puts a straw in her cup of water and sees that it looks like it is cut in half. Why does this happen?
500
The plastic spoon is an insulator and won't burn his hand since the heat can't go through it. The metal spoon is a conductor and will burn his hand since the heat can go through it.
Why should a chef use a plastic spoon instead of a metal spoon when cooking?
500
Many pathways, each bulbs has own source of electricity, bulbs are bright, if one bulb is removed the others will still stay on
Describe a parallel circuit focusing on the number of pathways, the brightness of the bulbs and what happens when one bulb is taken out.
500
Her body produces heat and then her coat, which is an insulator, will trap the body heat in. The coat slows down the heat loss.
Why does Jillian wear a coat on a winter day?
