This is an activity to do when there is a solar eclipse!

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

In this activity, learners construct a paper glider to experiment with aerodynamic forces.

In this activity about the relationship between food and energy (page 8 of PDF), learners estimate average daily baseline energy (Calorie) needs and energy needs for different levels of activity.

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

This activity provides step-by-step instructions on how to build a rain stick, a musical instrument originating in South America.

In this activity about electricity, learners build and test a paper clip switch to turn on a light bulb.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this activity about daily rhythms (on page 17 of the PDF), learners will explore circadian patterns in humans, animals and plants.

In this activity, learners explore sound by constructing their very own instruments using PVC pipes, soda bottles, and a straw.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this investigation, learners explore the force known as buoyancy by placing various objects into water and observing how they behave (for example, which sink more quickly, which float, how much wat

In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.

Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

Make two firefly lanterns, then program them to blink to one another and change colors.

In this activity about electricity, learners identify parallel and series circuits. First, learners examine and label diagrams of complete circuits.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.
