Chemistry Labs, Week 1

This week, the kids performed two chemistry experiments:

Experiment 1.1: Air Has Mass: The yardstick balances with two uninflated balloons. Once one balloon is inflated, the yardstick tips in that direction. Indicating that air has mass.

Experiment 1.2: Air Takes Up Space: After placing the glass upside down in a sink of water, the paper towel is still dry.
