Sam is doing an experiment to see if the temperature of an object changes when rubbed against another object. To do this, Sam takes the temperature of her skateboard's wheels. The temperature reads 77°F.
Which of the following could be the temperature of her skateboard's wheels right after she rides her skateboard for several minutes on the rough concrete?
32°F
86°F
68°F
77°F
Four thermometers were placed in glasses of 35°C (95°F) water, under different conditions. One of the samples was placed in direct sunlight. The picture shows the thermometers.
Which thermometer shows the most likely sample placed in direct sunlight?
thermometer W
thermometer X
thermometer Y
thermometer Z
John pushed a box of books across a carpeted floor. Then he pushed the box of books across a tiled floor. Which most likely caused the bottom of the box to have a greater increase in temperature, and why?
the carpet because it created more heat energy, which created more friction
the carpet because it created more friction, which created more heat energy
the tile because it created less friction, which created more heat energy
the tile because it created less heat energy, which created more friction
Linda goes to the park during the summer. She tries to go down the metal slide, but it is too hot. Which question will best help Linda understand why the slide is so hot?
Are there other children near the slide?
Are there other slides to play on?
Is the Sun shining on the slide?
Is the slide straight or curved?
Larry uses thermometers to measure the temperatures of four water samples sitting in sunlight. Which sample is the hottest?
Julie touched a set of train tracks, and they felt cool. After a train passed, she touched the tracks again. Which statement explains how the tracks most likely felt when Julie touched them again?
The tracks were the same temperature as earlier.
The tracks were much colder than earlier.
The tracks were warmer than earlier.
The trackers were a little cooler than earlier.
The pictures below show the temperatures recorded by two lab groups from the same thermometer at 3:00 p.m. on the same day.
Why did the groups get different results?
One of the groups did not use the correct language to record its measurement.
The groups did not use the same thermometer to make their measurements.
One of the groups measured the temperature at a different time of day.
The groups decided to use a different unit to record the temperature.
The picture below shows a cup of water and a thermometer on a sunny summer day, then the same beaker later in the day in shade.
Which of the following is the most likely temperature of the water in the shade?
0°C
30°C
35°C
25°C
Which question would help a student find out if friction is a source of heat energy?
Why does snow disappear in the spring?
Do objects feel warmer after rubbing them together?
What causes the ice cubes to melt in a glass of ice water?
How long does it take water to boil on the stove?
Bob rode fast on his bicycle. When he felt the tires after he stopped, they were warmer than before he started. Why were the tires warmer?
The tires rubbed on the road to create heat.
The tires mixed with the road to create heat.
The tires burned on the road to create heat.
The tires melted into the road to create heat.
Laura rubbed a wooden dowel with a cloth for 10 seconds. Then she rubbed the dowel with sandpaper for 10 seconds.
Which made the dowel hotter, and why?
the cloth because it creates a chemical reaction and absorbs more heat
the sandpaper because it is rougher and creates more friction, creating more heat
the cloth because it is more flexible and creates more points of friction, creating more heat
the sandpaper because it is darker and absorbs more heat
The pictures show Celine and Tony each pushing a box across the carpet. Celine's box has wheels and Tony's box does not.
After pushing the boxes across the floor, whose box would most likely feel the warmest on the bottom and why?
Celine's box would be the warmest because the wheels would create more friction.
Tony's box would be the warmest because there would be more friction created without the wheels.
Celine's box would be the warmest because the wheels would create less friction.
Tony's box would be the warmest because there would be less friction created without the wheels.
Jack pulled the box across the floor from point X toward his body.
True or False: When Jack pulled the box, heat energy was created, and the bottom of the box increased in temperature.
True
False
Jenny and Paul were outside on a sunny day. Jenny wore a white shirt and Paul wore a black shirt. Why did Paul feel hotter than Jenny?
He was sitting closer to the ground than Jenny.
He was sitting far away from Jenny.
Dark colors push away the Sun's energy.
Dark colors take in the Sun's energy.
Which of these benches is most likely the warmest?
Izzy's class is learning about heat energy. Heat energy can cause objects to change temperature. Izzy thinks the color of an object affects how quickly it changes temperature. Izzy's class does an experiment to test this idea. They choose four different colors of paper they want to test. They fold each different-colored piece of paper and place a thermometer inside of it. They record the beginning temperature and put the paper outside in the bright sunshine for two hours. After two hours, they record the temperature again. The picture shows their experiment.
What was the source of heat for Izzy’s class experiment?
friction
burning
electricity
sunlight

Read the passage about a student and his bicycle.
A student is performing an investigation. He uses a thermometer to measure the temperature of his bicycle tires. Next, he rides his bicycle around his neighborhood for thirty minutes. After his ride, he records the temperature of the tires again.
What question is the student most likely trying to answer?
How fast can the bicycle travel at top speed?
How much does the Sun heat up the ground?
How far can a bicycle travel in thirty minutes?
How much heat energy is caused by friction?
Answering which question would help a student decide that sunlight is a source of heat energy?
Why do ice cubes melt in a glass of water outside?
Why do car tires feel warm after driving?
Why can rubbing two sticks together to create a fire?
Why does water boil in a pot on a hot stove?
