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 conduct a simulation exercise related to public key encryption and try to intercept a message sent between two learners.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this math lesson, learners explore polynomial and rational function patterns.

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

In this math lesson, learners analyze the density of liquids in order to explore linear functions.

In this activity (on page 134 of the PDF), learners explore reaction time.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

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, learners investigate passive solar building design with a focus solely on heating.

In this math lesson, learners model exponential decay and exponential growth using M&M's, paper folding, and African rhino population data.

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners work in teams build and launch rubberband-powered foam rockets.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.
