Heavier and Lighter

Compare weights on a balance.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 50

A balance compares how heavy things are. The heavier side goes down. The watermelon is heavier than the apple.
The lighter side goes up. The apple is lighter than the watermelon.
Bigger isn't always heavier! A balloon is bigger than a baseball, but the baseball is heavier.
When the balance is level, the two sides weigh the same.
Try it with a grown-up! Hold a book in one hand and a sock in the other. Which is heavier? Which is lighter?
