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

In this inquiry-based lesson, learners measure the biomass of trees, calculate the carbon stored by the trees, and use this information to create recommendations about using trees for carbon sequestra

In this environmental health activity, learners investigate their breathing and pulse rates, and learn how these measurements are affected by physical activity.

Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in 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

In this activity, learners investigate visual perception as well as plan and conduct their own experiments.

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, learners grow germs collected from their hands and other objects. They cultivate the germs on a growth medium (such as slices of grapefruit or processed cheese) for a week.

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 very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

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

In this activity about sleep rhythms (on page 21 of the PDF), learners will collect data about their own sleep cycles and use a fraction wheel to examine their data.

Learners discover that their breath contains carbon dioxide, one of the pollutants found in car exhaust.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
