In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners drop impactors onto layers of graham crackers!

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

In this activity related to magnetism and electricity, learners create a magnetic field that's stronger than the Earth's magnetic field.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

Doctors often send a sample of blood to a lab, to make sure their patients are healthy.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

This activity is about the mural making process done about 9,000 years ago in Catalhoyuk, Turkey.

In this activity (page 26 of the PDF), learners make observations, formulate hypotheses and design a controlled experiment, based on the reaction of carbon dioxide with calcium hydroxide.

In this math lesson, learners use slices of bread and geoboards to explore several ways to divide a rectangle in half. Learners also identify equivalent fractions that represent one-half.

In this chemistry activity, learners will test the pH of various foods and household substances using cabbage.

In this math lesson, learners record and graph plant growth and interpret data. Learners plant seeds, and once the seeds sprout, record the change in height of the plants for several days.

In this activity, learners build simple alarms that they can attach to anything, such as a drawer or doorway. This activity introduces learners to electricity, circuits, and currents.

In this activity, learners build a bird that flies in place with help from a motor, wire, and some straws.
