In this physics activity (page 8 of the PDF), learners will explore the concept of inertia by attempting to run and stop quickly.

Experiment with liquids of different densities and create liquid layers. For example, oil and water have different densities: oil floats on water because it is less dense than water.

In this activity, learners explore the process of condensation.

In this activity, learners write a secret message in "invisible ink" and then use chemistry to view the writing.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

In this quick and simple activity, learners explore how the distribution of the mass of an object determines the position of its center of gravity, its angular momentum, and your ability to balance it

In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.

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

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this demonstration, learners will be "wowed" as three matches burn to form a triangular pyramid shape and "magically" rise off the table.

This is a classic exercise for visualizing the scale of the Solar System.

In this weather-related activity, learners make a portable cloud in a bottle.

In this activity, learners use a pencil, magnets, and mat board to illustrate Newton's Second Law.

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

In this activity, learners create a "mini sky" in a glass of water in a dark room.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.
