In this activity, you'll use a straw, a water bottle and a paper tube to make an instrument that's very much like a saxophone.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

This is an activity about friction as well as kinetic and potential energy.

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 activity, learners work in teams to construct human lung models from small plastic beverage bottles and balloons.

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

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

No glue is needed for learners of any age to become marshmallow architects or engineers.

See and hear how sound waves travel through different types of materials. Extend the experiment online and learn how you can "see" with sound waves using ultrasound.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

In this activity (page 105 of the PDF), learners measure heart rate and blood pressure and learn how to obtain consistent measurements during repeated tests.

Create a simple dual pendulum and get them to swing in identical ways. This is a simple, low cost, activity produced by the Exploratorium.

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area.

This activity (aka "snack") provides instructions for discovering your blind spot. It is an exploration of light and visual perception using simple materials you may have around the house.

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

Learners examine what happens when a tube spins in two directions at once. They push on a cardboard tube causing it to spin along its length while at the same time turning from end-to-end.

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

In this activity, learners see how many coins they can add to a full glass of water before the water overflows.

In this activity about weights and balances, learners create their own balance using paper cups. Then, learners explore how to compare the relative mass of objects.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
