In this activity about the brain and sleep (on page 138 of the PDF), learners measure their resting breathing rates. Learners will discover that breathing frequencies vary amongst individuals.

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

In this activity (18th on the page), learners conduct an experiment to examine memory.

Millions of organisms can live in and around a body of water.

Professor John Endler traveled to Trinidad in the 1970s to study wild guppies. In this activity, learners take part in an online simulation of Endler's work.

In this activity about humans and space travel (page 1 of PDF), learners compare and contrast the behavior of a water-filled plastic bag, both outside and inside of a container of water.

In this inquiry-based activity, learners investigate the basic forces of flight as they construct their own paper glider that represents a rainforest creature from Borneo (large, tropical island in So

This exercise can be used to stimulate the investigative nature of learners as they use forensic plant pathology techniques to prove the learners' innocence in a mock murder investigation.

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

In this activity (page 89 of the PDF), learners compare and contrast pitch and roll motions by using a Magic Carpet maze similar to one that was used for Neurolab investigations about microgravity.

In this activity (on page 146 of the PDF), learners will explore the effects of increased carbon dioxide in the bloodstream.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

Learners create a tool to measure how well they grip a wet object when their fingers are smooth versus wrinkly. Are smooth or wrinkly fingers better at holding on to the object?

In this multi-step experiment (page 4 of pdf), learners study tide pools, and then drop a "wave" (a 4-pound bag of beans or birdseed) on a shell to mimic the force of crashing surf on tide pool animal

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.
