Why does a popper bounce higher than its initial height?

• Because it is made of a different material.

• Because it has more elastic potential energy.

• Because it is lighter than a ball.

• Because it is dropped from a greater height.

What objects can the popper be used to launch?

• Rocks and pebbles.

• Ping-pong balls, marshmallows, or paper wads.

• Metal balls and coins.

• Plastic toys and rubber bands.

What is the benefit of exploring potential and kinetic energy concepts through hands-on activities?

• It makes the concepts less interesting.

• It makes the concepts more confusing.

• It makes the concepts harder to understand.

• It provides an exciting experience for students.
