The Sun’s Energy

Where does the energy that heats the land, air, and water come from?

• The moon

• Moving clouds

• Inside earth

• The sun

Anthony recorded the temperature at Location A, which was directly in the sun, with a temperature of 85°F. He then recorded the temperature at Location B, which was just a few feet away in the shade of a large tree.

• The temperature in Location A is the same as in Location B because they are close to each other.

• The temperature in Location A was cooler than Location B because it is farther from the sun.

• The temperature in Location B was much hotter than Location A because it’s closer to the sun.

• The temperature in Location B was cooler than Location A because it is not in direct sunlight.

Aliza investigated how the sun affects the temperature of the soil. To do this, she set up four cups of soil and put them each under a lamp. She left each cup of soil under the lamp for a different amount of time and then recorded the temperature of the soil at the end. Aliza's results are shown below.

What claim does this evidence support?

• The longer the soil is in the sun, the more the temperature will increase.

• Sunlight does not affect the temperature of the soil.

• The sun heats soil to the same temperature no matter how long the light is shining.

• The sun only heats the land and not the water.

Which tool would you use to measure the temperature of the air, water, or soil outside?

• Graduated Cylinder

• Thermometer

• Wind Vane

• Anemometer

Kaylee’s class went outside to observe a puddle of water several times on a sunny day. What best explains what happened to the puddle?

• Rain added water to the puddle.

• The weather became stormier.

• The sun’s heat changed the water.

• The weather became much colder.

Lewis leaves two jars of water on a windowsill. Both jars have the same amount of water in them. Which describes what Lewis will most likely observe in a few days?

• Both jars on the windowsill will be completely empty.

• Jar 1 will have more water in it than Jar 2.

• Jar 2 will have more water in it than Jar 1.

• Both jars will have the same amount of water.

Natalia left a full water bottle outside on a warm day. Which best describes what will happen to the water in the water bottle?

• The water will stay inside the bottle because it is closed.

• The temperature of the water will decrease because it is out in the sun.

• The water will get darker because it is outside.

• There will be more water in the water bottle because it will be later in the day.
