In this international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this activity, learners build one or more edible coral polyps and place them together to form a colony.

In this outdoor activity and fun race, learners first find the most common type of tree in a forest site.

In this activity, learners will explore the physics of air by making a snake kite.

In this activity, learners construct a device that allows them to look over ledges or around corners.

Learners design different shaped bandages for different purposes. First, they draw their designs on paper.

In this activity (on page 6 of the PDF), learners plot the path of the sun's apparent movement across the sky on two days, with the second day occurring two or three months after the first.

In this activity, learners will construct a measuring device (snake "string") to improve their observation skills.

In this activity, learners play a series of simple games to investigate navigation without visual and sound cues.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this activity, learners explore sound by constructing an instrument using some metal pipes, rubber bands, and a baseboard.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this experiment, learners isolate Deoxyribonucleic Acid (DNA) from onion cells using a simple extraction procedure.

In this activity, learners conduct an experiment to test how fast they can react. Learners try to catch a piece of paper with a ruler printed on it (or a ruler) as quickly as they can.

During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.

In this activity, learners examine their fingerprints and learn that they can be categorized by shape, but each fingerprint is unique.

In this self-measuring activity, learners measure and record the length of their foot.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range o

In this outdoor activity, learners discover that plants aren't just shoots (stem, branches, leaves, and flowers) growing above ground, but contain plenty of roots growing underground—more than half th
