Magnets
What is it called when two magnets pull toward each other?
ATTRACT
What is a force?
A push or a pull on an object.
What word means an illustration (picture) that shows the parts of something or how something works?
What is happening with the magnets to make the train rise up?
The magnets are REPELLING!
What is is called when you pay close attention to something with your senses? (Hint: Begins with the letter O)
Observing (observation)
What is it called when two magnets push each other away?
REPEL
What kind of force is it when you push a Jenga block with your finger?
Touching Force
What word means information that supports an answer to a question?
EVIDENCE
What is happening when the train starts to fall back down to the tracks?
The magnets are off and gravity is pulling the train down.
What are the ends of magnets called?
POLES
The magnets will attract (pull) toward each other.
What type of force is it when a ring magnet pulls a paper clip toward it?
Magnetic force
What word means observations or measurements recorded in an investigation?
DATA
When the train is balanced (floating), what TWO forces are equal?
Magnetic force and gravity
Are the forces on the floating paper clip and train equal or not equal when they are balanced?
EQUAL
What will happen if two magnets are facing each other with the same poles?
They will REPEL!
What is evidence of a force?
When an object starts or stops moving
What is gravity?
The downward pull that comes from our Earth. It is the non-touching force that makes objects fall toward the ground.
What kind of force causes the train to rise?
Magnetic force (repelling magnets)
How does the floating train fall back to the tracks?
The electromagnets are turned off, the train slows down and gravity pulls the train down to the tracks.
METAL
What is the non-touching pull force between Earth and other objects?
GRAVITY
What does "balanced forces" mean?
multiple forces of equal strength acting on an object
What type of magnets need to be used on the floating train?
Electromagnets
What is the floating train a useful new invention?
It is fast, safe to ride, and good for our environment since it uses magnetic force.
