In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

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 build styrofoam boats powered by twisted rubber bands.

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.

In this activity, learners will explore how density is affected by temperature and how that can create currents.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

Learners color and cut out a spiral-shaped snake. When they hang their snake over a radiator, the snake spins.
