Heavy and Light

Compare mass with a balance scale.

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

What children learn in Level 25

Mass tells how much matter is in an object: how heavy it is. A balance scale compares the mass of two things.
The heavier side goes down, and the lighter side goes up. The book is heavier than the feather.
Bigger isn't always heavier! A big balloon is lighter than a small rock.
Your turn! Put these in order, from the lightest to the heaviest.

Georgia Standards of Excellence in Science:
