• true

• false

Multiple Choice

What would happen if you touched a south pole end of a magnet to a north pole end of another magnet?

• they would be attracted to each other

• they would be repelled from each other

Multiple Choice

What would happen is a north pole of a magnet came close to a north pole of another magnet?

• they would be attracted to each other

• they would be repelled from each other

According to the description The Uncle Milton Star Wars Science: Jedi Force Levitator “...is definitely one of the coolest Star Wars toys on the market today. It uses a Jedi Training Wand that creates electrostatic energy to “magically” levitate the eight included force deflectors”.

The Bubble Levitator

Open Ended

Your friend thinks that the Jedi Force Levitator is magic because you can only move an object by touching the object. Do you agree or disagree? Explain why.

Open Ended

What patterns do you notice in the movement of the Levitator and the bubble?

You and your classmates would like to better understand how the Force Levitator levitates the bubble. An image of the disassembled levitator can be seen below.

Draw

Use arrows to label the forces acting on the Force Levitator and the levitating bubble in the diagram​. Label the forces as attractive or repulsive.

Dropdown

Write a research question that you could investigate to decide how the Force Levitator works. Your research

questions should be based on cause and effect relationships and should help you understand how the Force

Levitator works.
