In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity (located on page 9 of the PDF), learners are introduced to Aesop's fable, "The Crow and the Pitcher." In the story, a clever crow drops pebbles into a pitcher to cause the water level

In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea

Learners investigate how the temperature of water affects its density.
