Learners smell balloons filled with different scents to guess what's inside. From this, they infer the presence and motion of scented molecules.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.

In this activity, learners identify different classes of matter based on physical properties.

In this activity, learners discover that sand is the major ingredient in glass.

Albert Einstein proved that space bends around anything that has mass. This activity uses Jell-O's ability to bend around objects as a model for space bending around planets and stars.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
