This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this physics activity, learners use square blocks to explore how towers fall. Learners attach a piece of string to the side of a block and then construct a tall tower on top of this base block.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this engineering activity, learners design parachutes to give toy figures safe landings. This activity is great for practicing an important STEM skill--changing only one variable at a time.

In this quick activity (on page 2 of the PDF under GPS: Body Electricity Activity), learners will observe how dry breakfast cereal appears to dance when it gets close to a balloon charged with static

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.
