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

In this activity learners will "rescue" animals from tape and then sort the animals. Learners will use science process skills such as categorizing and making observations while they play.

In this experiment, learners will explore whether increased carbon dioxide makes our oceans more basic or more acidic.

In this activity, pairs of learners will create two make-believe dig sites by burying chicken bones in plaster of Paris--a powder that hardens when wet.

Learners test their memory and ability to learn memory strategies in this game. Partners start with an array of poker chips, coins, or paper squares on the table.

In this activity, learners train to increase muscular strength and improve upper and lower body coordination by performing the “bear crawl” and the "crab walk.” Learners perform the exercises over tim

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

In this activity, learners solidify their conceptualization of cells by building a model of a cell in a ziplock bag.

In this culinary activity, learners use multiple senses (sight, smell, touch, and taste!) to explore real seaweed samples.

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

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

This lesson is designed to serve as an introduction to the immune system. It can stand alone or it can lead into further studies of the immune system.

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.
