The demonstration/experiment provides quick proof that air has mass.

Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.

In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

In this activity, learners explore clouds and how they form.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

In this chemistry demonstration, acid rain is simulated in a petri dish.
