Lesson: Earth pulls down on objects with a force called "gravity."
3.
Lesson: Fire is a rapid chemical reaction that is both hot and burns.
4.
Lesson: Metal conducts electricity.
5.
Lesson: For every action there is an equal and opposite reaction.
6.
Lesson: An object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
7.

Lesson: Energy is transferred, never destroyed.
18.
Lesson: Glass is a transparent solid.
19.
Lesson: Objects with less density than water will always float on water.
20.
Lesson: Unbalanced forces can cause objects to start moving, stop moving, or change direction.
