Physical Science Grade 5 Review

The two objects shown are the same size. However, the object on the left is made of wood, and the other object on the right is made of plastic. Which of the following properties of the objects will be the same?

• texture

• volume

• weight

• mass

Susan blew up a balloon until it was completely full and as big as a soccer ball. Which of the following correctly describes the air inside the balloon?

• The air is a gas that cannot be compressed by any means.

• The air is a gas that always forms a round shape when compressed. 

• The air is a gas that expands to evenly fill the space inside the balloon.

• The air is a gas that will flow evenly and steadily from inside the balloon if punctured.

Imagine you have a bucket of saltwater. Which of the following would be the best way to remove the water so that you're left with only salt?

• Freeze the saltwater. The water will sink to the bottom and the salt will rise to the top.

• Boil the saltwater. The water will evaporate and only the salt will remain.

• Leave the saltwater to sit for a long time. The salt will settle to the bottom.

• Stir the saltwater for a long time. The salt will form a crystal.

Brian and Emily are testing different paper airplane designs to see which will allow a plane to go the farthest. Emily folds her plane and attaches a paperclip to the front of it. After she throws the plane, it travels about fifty feet and then starts to fall to the ground.

Why does the plane eventually fall to the ground?

• The force of air resistance stops acting on the plane.

• The plane was not designed to carry a load like the paperclip. 

• The force of gravity is greater than the forces keeping the plane in the air.

• The paperclip creates a magnetic force that attracts the plane to the ground.

 A toy car rolling along different surfaces will experience different amounts of friction. The toy car would encounter the most friction when rolling on which of the following surfaces?

• a bumpy section of road

• a sheet of glass

• a smooth wooden board 

• a piece of construction paper

 David and Peter were moving a bookshelf across the carpet in their classroom. Even though they pushed as hard as they could, the bookshelf would only move a few inches at a time.

Which of the following best explains what happened as they tried to push the bookshelf?

• The force of gravity opposed the motion of the bookshelf. 

• The force of friction opposes the motion of the bookshelf. 

• When they tried to push the bookshelf, air resistance acted against them.

• When they pushed the bookshelf, the bookshelf pushed back with an equal and opposite force.

George's science teacher has a mixture of table salt and iron filings. Which of the following would be the best way to separate the salt and the iron filings?

• use a magnet to pull the iron filings from the salt

• add food coloring to the mixture to make the salt change color 

• pour them into a beaker of water and see if the iron filings float

• heat up the mixture to see if the salt or the iron filings will burn away

Elise is learning about how magnets have a negative and positive pole. What happens if you try to touch the positive ends of two magnets together?

• The positive poles will repel each other.

• The positive poles will be attracted to each other.

• The positive poles will neither attract nor repel each other.

• The positive poles will create gravity and attract other objects.

• baking soda

• sand

• sugar

• table salt

 Mr. Schiller’s class is investigating how magnets attract and repel different objects as well as other magnets.

Which of the following best explains what would happen to the magnets above if they were pushed closer together?

• The negative and positive poles will repel each other.

• The negative and positive poles will cancel each other out.

• The negative and positive poles will be attracted to each other.

• The negative and positive poles will neither attract nor repel each other.
