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

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 activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this activity, learners explore the possibilities of clay as a natural material.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

In this activity, learners will create their own lava lamps. Learners will explore density, effervescence and chemistry through this activity.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity, learners explore how hot and cold water move. Learners observe that temperature and density affect how liquids rise and fall.

In this physics activity (page 6 of the PDF), learners will demonstrate air has weight by comparing an inflated balloon to a deflated one.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity, participants will learn how stars form from the dust and gas that exists in space clumping together.

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