Physical Science 4th Grade Quarter 1

Jim likes to play baseball. The field has a camera that measures the speed of the balls just before they hit the catcher's mitt. Here are the speeds:

Ball A 32km/h

Ball B 17km/h

Ball C 28km/h

Ball D 26km/h

Which ball did Jim throw harder?

• Ball A, because throwing harder makes a ball go faster

• Ball B, because throwing softer makes a ball go softer

• Ball C, because throwing harder makes a ball go slower

• Ball D, because throwing softer makes a ball go faster

Hannah spilled some salt on her kitchen counter. She pounded her fist on the table, and the grains of salt moved. Why did the salt move?

• The spilled salt transferred energy to the table.

• Vibrations made by Hannah's pounding transferred energy to the salt.

• The air above the table transferred energy to the salt.

• Heat from Hannah's fist transferred energy to the salt.

Max likes to skateboard. Sometimes when he lands a jump, his board hits the ground and makes a loud noise. Why does this happen?

• Some of Max's thermal energy changes to stored energy when the board hits the ground.

• The ground absorbs all the board's energy.

• Some energy from the board is transformed to sound when the board hits the ground.

• All of Matt's energy of motion is transferred to the board when the board hits the ground.

Ruby kicked a soccer ball to Matt. The ball bounced from Matt's head into the goal. What happened to the ball when it collided with Matt's head?

• It stopped moving.

• It gained chemical energy.

• It lost all its energy of motion.

• It changed direction.

On a sunny day, Maria put two bowls of water outside. One bowl was in the sunshine, the other in the shade. They both had the same temperature of 28 degrees Celsius before she set them out. She tested the temperature of the water after one hour. The water in the sun was 33 degrees Celsius. The water in the shade was 28 degrees Celsius. How did the thermal energy of the water in the bowls change?

• The thermal energy of the water increased in both locations.

• The thermal energy of the water stayed the same in both locations.

• The thermal energy of the water decreased in the sun and increased in the shade.

• The thermal energy of the water increased in the sun and stayed the same in the shade.

On a sunny day, Maria put two bowls of water outside. One bowl was in the sunshine, the other in the shade. They both had the same temperature of 28 degrees Celsius before she set them out. She tested the temperature of the water after one hour. The water in the sun was 33 degrees Celsius. The water in the shade was 28 degrees Celsius. Which is the best explanation of what Maria observed?

• The energy of light was transferred to the water in the sun, making it cooler.

• The energy of light was transferred to the water in the sun, making it warmer.

• The energy of light was transferred to the water in the shade, making it warmer.

• The energy of light was transferred to the water in the shade, making it cooler.

How does a switch affects the transfer of electric energy?

• When you turn on a switch, the path of the circuit is complete. The current flows to the light bulb to light it up.

• When you turn on a switch, the path of the circuit is incomplete. The current does not flow.

• A switch does not affect the transfer of electric energy.

What are two materials that would allow electrical energy to flow?

• paper

  marker

• eraser

  crayon

• plastic ruler

  wood stick

• scissor blades

  metal key

How does the transfer of energy flowing through wires produce light?

• An electric circuit never has energy.

• The energy can produce light if the wires are not connected.

• An electric circuit is not complete.

• An electric circuit provides a complete path so that electric current can flow.
