 Four items are placed the same distance from the magnet. Which one of the objects will be the easiest for the magnet to pull?

• A 1-gram piece of tissue will be the easiest for the magnet to pull.

• A 2-gram bouncy ball will be the easiest for the magnet to pull

• A 3-gram metal spoon will be the easiest for the magnet to pull.

• A 4-gram iron fastener will be the easiest for the magnet to pull

The two north poles of a magnet are facing each other.

      What effect do these poles have on one another?

• The poles will cause the magnets to attract to each other.

• The poles will cause the magnets to remain still.

• The poles will cause the magnets to spin around each other.

• The poles will cause the magnets to repel.

A magnet and a paper clip are placed on a table. Describe how the distance between the two objects will affect the magnetic field. Choose two statements.

• The farther the magnet from the object, the stronger the magnetic field.

• The closer the magnet to the object, the stronger the magnetic field.

• The closer the magnet to the object, the weaker the magnetic field.

• The farther the magnet from the object, the weaker the magnetic field.

• The distance between the magnet and the object does not affect the magnetic field.

Will the magnets shown above repel each other? Explain.

• Yes, since the opposite sides of the magnets are facing each other, they will repel each other.

• No, because the opposite sides of the magnets are facing each other

• Yes, since the same sides of the magnets are facing each other, they will repel each other.

• No, because the same sides of the magnets are facing each other.

Which statement below would the best to show non-touching forces? 

• Sarah asks if a stick will attract to a magnet

• Tommy asks if a magnet can change colors.

• Paul asks what color each of the magnets’ sides are.

• Lucy asks if they can make magnets move away from each other

 Dora plans an investigation using one magnet to pick up a pile of metal paper clips.  She already knows that the paper clips will stick to the magnet because the two objects attract. 

 Which question is Dora most likely trying to investigate?

• What materials are used to make a magnet?

• Why do paper clips bend easily if they are made from metal?

• At what distance will the magnet be able to pick up the paper clips?

• What touching forces are making the paper clips stick to the magnet?

 Leaders in a city want to sort through the city’s landfill to pick out metal cans that can be recycled.  It would take a long time to do this work by hand.  Engineers know that magnets attract metal.  They decide to build a big magnet to move above large piles of trash. 

        Which evidence best supports the engineers idea?

• The magnet will draw the metal cans up and out of the trash piles.

• The magnet will cause the metal cans to move to the side into a neat pile.

• The magnet will flatten and recycle the cans while they are being collected.

• The magnet will use electricity to sort the metal cans from the nonmetal items.

Juan sets up three different magnets at different distances from metal paper clips.  He collects data in the table below. What conclusion can Juan make by looking at his data?

• Magnets will attract paper clips at any distance.

• Magnets will attract paper clips the farther away they are from the magnet.

• Magnets will attract paper clips that are made of nonmetal.

• Magnets will attract paper clips that are closer to the magnet.

Choose the best claim to explain how the train rises without anything touching it.

• The Train will rise without anything touching it because of a non-touching force.

• The train will rise without anything touching it because of a touching force.

• The train will rise without anything touching it because of gravity.

• The train will rise without anything touching it because it is magic.
