This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

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

This modeling activity allows learners to discover for themselves what Mendel uncovered in his famous pea experiments.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this activity related to plant biotechnology, learners transform a strain of E. coli using green fluorescent protein from a bioluminescent jellies.

In this physics activity, learners recreate Galileo's famous experiment, in which he dropped a heavy weight and a light weight from the top of the Leaning Tower of Pisa to show that both weights fall

In this activity related to plant biotechnology, learners use the tissue culture process to rapidly produce clones (genetic copies) of a particular plant (cauliflower, rose cuttings, African violet le

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this activity, learners explore deoxyribonucleic acid (DNA), a nanoscale structure that occurs in nature.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this physics activity, learners assemble and/or investigate a pendulum "snake." Several large steel hex-nuts are suspended on strings of successively increasing length to form a series of pendulums

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

In this physics crime lab or demonstration, learners pretend they are criminologists and must find the "muzzle velocity" (speed of the bullet as it leaves the gun) of a gun used to commit a crime.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners explore how genetic switches function and the role of genetic switches in the process of evolution.
