Does the magnet hold the paper clip through 50 pieces of paper?
yes
no
Why do you think the magnet does not hold 50 pieces of paper?
The magnet is round.
The magnet is too weak to hold through 50 sheets of paper.
The magnet is turned off.
What question could these students be investigating?
How strong is the paper clip?
Does the number of paper clips change the force of the magnet?
Can a magnet attract an object that it is not touching?
Does the direction of the magnet matter?
What will increasing or decreasing the amount of paper do?
Adding more paper will change nothing.
It will weaken the magnet itself.
More paper will weaken the amount of force exerted on the paper clip.
Decreasing paper will make the force of the magnet stronger.
Which forces are acting on the dominoes that are standing up?
gravity
magnetic force
balanced force
friction
This tractor has an electromagnet being used to lift heavy scrap metal. Why would the scrap metal fall?
The magnet was turned off.
The magnet was turned on.
The metal was too heavy.
The magnet is turned backwards.
These two men are trying to move this box across the room. Will their strategy work? Why or why not?
It will work because they are both pushing.
It will work because two men pushing will make the box light.
It will not work because they are pushing against each other.
It will not work because one is pushing and one is pulling.
Will this man be able to push this car very far alone, or will he need help?
He will be able to push it very far. It is a small car.
He is pushing the car.
He will not be able to push the car very far alone. The car is too heavy. The forces are unbalanced.
He will not be able to push it very far, because the car is pushing back.
What are these two men creating right now?
They are creating a balanced force that will result in the couch moving.
They are creating a pull which will result in the couch moving.
They are creating an unbalanced force that will result in the couch moving.
They are creating a magnetic force that will result in the couch moving.

What will happen to the girl in the pink shirt if the boy in the green shirt pulls harder than her?
The boy will fall because he pulls too hard.
The girl will go backwards because of his push.
The girl will go forward because his force is stronger than hers.
The girl will fall because she doesn't know how to skate.
