Henry’s mom wanted to boil a pot of water on the stove. He knows she turned on one of the burners but he is not sure which one. Henry is too far away from the stove to feel the heat from the burner. Other than feeling the heat from the burner, how else can Henry recognize which burner is hot?
It will begin to shake.
It will be glowing.
It will make a loud noise.
It will turn into a liquid.
Rylee was testing out a lightbulb at different settings. The lightbulb was put on a dimmer switch, so the amount of light it gave off could be changed from dimly lit to brightly lit. At which brightness was the bulb most likely the hottest?
A
B
C
D
Peter placed a thermometer in the sunlight by a window without shades in his house. He checked the temperature reading on the thermometer three times during the day. Look at the thermometer readings he took. How did the temperature change during the day, and what caused this change in temperature?
The temperature increased because heat from the kitchen warmed up the room at lunchtime.
The temperature decreased because a cold front came in, and it began to snow.
The temperature increased because the sun was shining in the window and caused the temperature to rise.
The temperature decreased because there were lots of clouds in the sky, causing the temperature to drop.
Jeremy is closely examining the lightbulb in a lamp. What two forms of energy will Jeremy most likely observe from the bulb?
sound energy
heat energy
magnetic energy
light energy
mechanical energy

Thomas rode his bicycle on a sidewalk on his way home one night. He used his brakes to stop. The bicycle skidded before stopping. Then Thomas felt his tires. He noticed that their temperature had changed. What kind of change in temperature did the tires have, and what caused the change in temperature?
The temperature of the tires increased because the friction between the tires and the sidewalk created heat.
The temperature of the tires decreased because there was no friction between the tires and the sidewalk, which caused them to get colder.
The temperature of the tires increased because the sun was shining bright, and that heated the tires.
The temperature of the tires decreased because it was a cold day, and the cold air caused the tires to get colder.
