Straight line ------->
How does light travel? Draw a picture to show an example.
|
Sun, burning, friction, electricity
Name 4 ways heat is produced.
|
In a circuit (circular closed path)
How does electricity travel?
|
Particles are close together, has its own shape
Describe the properties of a solid
|
Vibrations (moving back and forth quickly)
How is sound produced?
|
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?
|
From a warm object to a cooler object
Describe how heat travels.
|
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.
|
When the temperature is below 32 degrees and it can freeze or solidify.
When does a liquid become a solid?
|
slowly.
An object with a low pitch vibrates...
|
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.
|
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?
|
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.
|
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.
|
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.
|
Must be shiny, metal and smooth
In order for an object to reflect light, what 3 properties must it have?
|
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.
|
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?
|
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.
|
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.
|
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?
|
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?
|
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.
|
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?
