In physics, the term “work” means something different than the way we use it in everyday life. In this activity, you will learn what we mean when we use the term in physics and will explore how to calculate it.
MATERIALS
- Heavy object (e.g. a book, large full water bottle, small dumbbell weight, etc.)
- Kitchen, bathroom or luggage scale
- Ruler

Learn about the three classes of levers and investigate how they help us do work by experimenting with your own levers at home.
MATERIALS
- 2 rulers (at least 1 that is not bendy) or 1 ruler and 1 wooden paint stir stick
- Pencil
- 2 plastic cups or containers (should be the same)
- Tape
- Many identical small objects to serve as small weights (ex: coins, buttons, legos, marbles) - something pourable like sand, lentils, or sugar may also work but might make a mess
