Learning About Air as Matter

Our second Science Enrichment class was so much fun! Mrs. Deeley used activities with balloons to help us prove that air is matter, and therefore has mass (weight) and takes up space. We also blew up balloons and placed them in coolers with either hot water or ice to see how the particles in the air moved to make the balloons either expand or contract! So much learning and so much FUN!

Mrs. Deeley explains how to measure the circumference of the balloon in centimeters.

Wow... This balloon filled with air is heavier than the empty one! Air has mass.

Exploring the effects of heat and cold on air.

Measuring to see how the circumference changed after being in a hot or cold environment.

Why can't we blow up the balloon inside the bottle???
