In this activity, learners work in groups to determine the mass and volume of four samples: glass marbles, steel washers or nuts, pieces of pine wood, and pieces of PVC pipe.

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this physics activity, learners will explore buoyancy.

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

In this activity, learners investigate convection by using food coloring and water of different temperatures.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this activity, learners use basic measurements of the Earth and pieces of rock and iron to estimate the mass of the Earth.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.
