In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.

In this activity, learners watch a figure "magically" float up through the air.

In this activity, learners will discover how fossils are dug out of the earth by carefully exposing treasures hidden in an artificial rock that is easily made at home.

In this activity, learners play a game to simulate the food chain.

In this plant science activity, learners role play as vegetables and weeds competing for nutrients.

Pairs of learners play the roles of programmer and robot. The programmer gives specific directions to the robot to accomplish a simple task (e.g. walk across the room and pick up a pencil).

In this simple and fun activity, learners build a tower of cups to explore distribution of weight. Learners make predictions about their towers and test their designs.

In this activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

This activity provides instructions for making an aircraft that can really fly using a straw and paper hoops!

In this activity on page 7 of the PDF (Chemistry—It’s Elemental), learners use iodine to identify foods that contain starch.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this activity on page 10 of the PDF, learners develop an experiment to answer the following question: "How much water can the hydrogel in a baby diaper hold?" Use this activity to explore polymers,

In this activity, learners will explore how computers represent pictures using pixels.

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.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique.

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

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.

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