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.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

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, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

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 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.

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

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

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

In this online activity, learners see simulations of how processes shape the Earth, and see estimates of how long these processes take.

This activity (on page 3 of the PDF under GPS: Body Electricity Activity) is a full inquiry investigation into conductivity.

In this activity on page 6 of the PDF (Chemistry—It’s Elemental), learners explore some of the properties of copper using a few common household ingredients.

This activity demonstrates liquefaction, the process by which some soils lose their solidity during an earthquake.

In this biology activity (page 8 of the PDF), learners will explore how saliva assists in the beginning of the digestive process.

In this graphing exercise (page 2 of the pdf), learners compare their own height to the length of various sharks.
