Energy Leap Questions

A student uses a blender to make a milk shake. He plugs the blender into a wall outlet. He adds ice cream and milk and turns the blender on. While the student is running the blender, the phone rings. He does not hear the ring over the noise of the blender. After he turns the blender off, he pours his drink into a glass. He observes that the base of the blender is warm.

Which statement describes a way that energy is transferred in the blender?

• A. The blender’s kinetic energy changes directly into light energy.

• B. The blender’s electrical energy changes directly into sound energy.

• C. The blender’s heat energy changes into both mechanical and sound energy.

• D. The blender’s mechanical energy changes into both heat and sound energy.

Students are practicing softball on a windy day. The pitcher throws the softball toward the batter. The students notice that the softball moves faster after it is hit by the bat than when it is thrown by the pitcher. Which statement best explains what happens to the energy of the softball when it is hit by the bat?

• A. When the bat hits the ball, energy transfers from the softball to the bat.

• B. The softball is still moving, so there is no transfer of energy to or from the softball.

• C. There is a transfer of energy from the softball to the bat, increasing the energy of the bat’s movement.

• D. There is a transfer of energy from the bat to the softball, increasing the energy of the softball’s movement

Nine-banded armadillos are usually active at night. They have very small eyes and cannot see objects that are far away. They use their noses to find food that is as deep as 20 centimeters underground. Armadillos also use their noses to loosen soil and use their claws to dig in the soil. They use their good hearing to listen for predators.

Part A

Which claim is supported by the information about armadillos? ^

• A. Armadillos use their sense of smell to find food.

• B. Armadillos use their sense of touch to hide from predators.

• C. Armadillos use their sense of hearing to find food that is far away.

• D. Armadillos use their sense of sight to see predators that are nearby.

D. Armadillos use their sense of sight to see predators that are nearby.

Part B

An armadillo is looking for food at night and finds a new object in its environment. Which statement describes how the armadillo will most likely use its senses to take in information about the new object to determine if the new object is food?

• A. The armadillo will use its ears and compare the sound the object makes to known sounds.

• B. The armadillo will use its nose and compare the smell of the object with known smells.

• C. The armadillo will use its eyes and compare the look of the object with the look of known objects.

Heating with Solar Energy Many homes are heated by using electricity. Electricity is usually produced in a power plant. The electricity is then delivered to homes through wires. Other homes are heated by burning fuels such as natural gas. These fuels must be transported to homes through pipes. Some homes are heated by using solar energy. Energy from the Sun can also be used to heat water.

Figure 1 and Figure 2 show two methods of heating a home in different parts of the country. The steps for each method are also shown.

Figure 1. Heating with Electricity from Solar Energy

Use the information in Figure 1 to answer the question. Session 1

Which energy conversion happens in Step 1?

• Solar energy is converted to light energy.

• Heat energy is converted to solar energy.

• Electrical energy is converted to heat energy.

• Solar energy is converted to electrical energy.

Use the information in Figure 2 to answer the questions.

Part A

Which evidence shows that energy is transferred from place to place by light?

• A The liquid that resists freezing is moved by the pump to where light is shining.

• B Energy from the hot water is used to heat up the room heaters.

• C The liquid that resists freezing is used to heat up the water in the water heater.

• D Energy from the Sun is used to heat up the liquid that resists freezing.

Refer to your answer from Part A on the previous question from Figure 2.
