Which is a natural source of heat?

• light bulb

• oven

• fire

• wood

Jenna’s class was studying heat. They were using a table to sort different actions.

Which question is the BEST title for Jenna’s sorting table?

• How do you control heat?

• Which actions create heat?

• Where does all heat come from?

• Why does movement create heat?

Katie's mother accidentally touched a hot stove burner and said, "Ouch!" Katie asked how the stove burner got so hot and her mother said, "Electricity is turned into heat energy." Katie wondered if there were other sources of burning to produce heat energy around the house.

Of these sources of heat energy that Katie found, which TWO are produced by burning?

• toasting a piece of bread in the toaster

• using a hair dryer to dry wet hair

• a cat warming your legs while sitting on your lap

• a bathtub full of warm water warming your body on a cold day

• fire in the fireplace warming the room

Tom walked out on his deck to get his food off the grill. The deck floor was so hot, it burned his feet. Which question should Tom ask to describe why the deck was hot?

• Was it heated by energy transferred from the grill?

• Was it heated by energy from the sun?

• Was it heated by a chemical reaction caused by an energy source?

• Was it heated by friction between his feet and the deck?

Mr. Bryan made a chart to record student answers to the question of the day, but he forgot to write the question at the top of the chart.

What was Mr. Bryan’s question of the day?

• What things do we need to measure heat?

• What are some examples of burning?

• What are some ways heat energy is transferred?

• What are some ways heat energy can be produced?

Which piece of scientific equipment measures temperature?

• barometer

• thermometer

• conductor

• insulator

Ron was investigating the effect of the sun on a cup of water. He recorded the temperature of the cup of water before he placed it outside in the sun.

Which of these could have been the temperature of the cup of water before he placed it outside in the sun?

• 70 degrees

• 60 degrees

• 78 degrees

• 85 degrees

A group of students conducted an investigation to determine which of four objects would absorb the most heat energy from sunlight. They placed four objects in direct sunlight and used thermometers to measure the temperatures of the objects.

Which BEST describes the objects the students used and explains the data collected after 15 minutes?

• The students used four different objects of the same color. Object 3 would have had the greatest density because it had the least temperature increase and absorbed the most energy from the sun.

• The students used four different objects of the same color. Object 2 would have been the largest object because it had the greatest temperature increase and absorbed the most energy from the sun.

• The students used four of the same object but different colors. Object 3 would have been the darkest colored object because it had the least temperature increase and absorbed the most heat from the sun.

• The students used four of the same object but different colors. Object 2 would have been the darkest colored object because it had the greatest temperature increase and absorbed the most heat from the sun.

Ms. Kelsey's class is investigating the effects of sunlight on soil and water. They filled cups with equal amounts of soil and water and placed a thermometer into each cup. The cups were placed in two different locations on a clear summer day. The students measured the temperature of each cup during the day.

Which data table indicates the MOST LIKELY temperature measurements for the cups receiving full sun all day?

• 
• 
• 
• 

Which TWO investigations would provide evidence that the sun effects the temperature of objects at different rates?

• 1. Place 2 objects in the sun and 2 objects in the shade

  2 . Using your hand, record the temperature of each object after 1 hour

  3. Record your observations

• 1. Pick 1 object

  2. Place it in the direct sunlight

  3. After 1 hour, use a thermometer to measure the temperature of each object

• 1. Pick 2 objects

  2. Place them in the shade

  3. After 2 hours, measure the temperature of each object with your hand

  4. Record the temperature

• 1. Pick 2 objects

  2. Using a thermometer, record the starting temperature of each object

  3. Place them in direct sunlight and record the temperature of each object every hour for 5 hours.

• 1. Pick 4 objects

  2. Place 2 objects in the sun and 2 objects in the shade

  3. Using a thermometer, recording the starting temperature of each object and then check the temperature multiple times during the day

  4. Record the time and temperature of each object
