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

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

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

In this physics activity, learners conduct two experiments to explore free-falling.

In this activity, learners play a simple card game to learn the sequence of events in the transmission of nervous system signals.

In this lesson that includes hands-on activities and demonstrations, learners discover that it is the tilt of the Earth's axis (not its proximity to the sun) that causes the seasons.

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

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

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

Play-Doh is conductive! Use the semiconductive qualities of Play-Doh to make your own squeezable instrument. Pico Cricket is required.

This is a perfect summertime lunch activity! Pico Cricket is required (micro controller). First, get a bunch of cut up fruit, line them up, then plug a piece of fruit with a Pico Cricket sensor clip.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

In this activity, learners investigate how increased carbon dioxide (CO2) emissions from the burning of fossil fuels is changing the acidity (pH) of the ocean and affecting coral reefs and other marin

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

This lesson focuses on molecular motion in gases. Learners compare the mass of a basketball when it is deflated and after it has been inflated.

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

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this activity (page 10), learners explore how molecules self-assemble according to forces of attraction and repulsion.
