In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity, learners surprisingly pop balloons without touching them using orange peels. This Mr.

Learners mix vinegar and baking soda together in a bottle to create a chemical reaction. The reaction produces a gas, carbon dioxide, which inflates a balloon attached to the mouth of the bottle.

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.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

In this activity about gravity (page 6 of the PDF), learners will come to understand how all objects will fall at the same rate, but that air will slow things down.

This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.

In this demonstration, learners observe how liquid nitrogen both boils and freezes ingredients to make ice cream in two minutes.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners explore inertia as they attempt to whip a strip of paper out from under two coins dangling on the rim of a water glass.

This demonstration activity models how Venus appears from Earth.

In this demonstration about momentum, use physics to distinguish between a hard-boiled egg and a raw egg without cracking them open.

In this activity, educators can demonstrate how the nanoscale arrangement of atoms dramatically impacts a material’s macroscale behavior.

In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.
