Learners develop an understanding of air pressure in two different activities.

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

Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this activity, learners will explore the physics of air by making a snake kite.

In this activity, learners discover how hard their hearts work to pump blood.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this demonstration, learners investigate mass, gravity, and acceleration by dropping a wooden bar with a balloon attached to its underside, a mass suspended from it by rubber bands, and a sharp-poi

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