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

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

In this craft activity, learners will explore the structure and purpose of antelope horns by constructing their own headband using toilet paper rolls and yarn.

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

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 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

We listen to stereo music systems, tv's, and radios because it simulates being where the sound originates.

In this activity (located on page 5 of PDF), learners work in groups to create dig sites for display.

In this outdoor activity, learners construct bird feeders and set them up at to investigate bird behavior for one or two weeks. Multiple feeder designs are suggested.

In this activity, learners will create their own coral polyps - the basis for a coral reef.

In this activity, learners create a sound visualizer from common materials to help see the vibrations created by sound. Sounds from a tone generator make salt dance on a vibrating balloon membrane.

In this activity, learners explore cooked chicken wings and identify the various parts including: bones (radius, ulna, humerus, shoulder joint, elbow joint), tendons, and cartilage.

In this activity, learners create slime to model mucus and examine how it collects simulated particles. Mucus keeps particles from the environment out of our lungs when we breathe.

Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

In this outdoor activity, learners build bird nests and place them in the activity area, then play the role of naturalists as they try to locate each other's nests.
