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 activity, learners explore how to protect their skin while applying pesticides to plants.

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

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.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this activity (p.3-4 of PDF), learners learn about disease transmission and antibiotic resistance.

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

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity (p.26 of PDF), learners discover why mushrooms have spots. Learners use a balloon, toilet paper, and water to simulate what happens as mushrooms grow.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

In this demonstration (9th on the page), learners explore eyewitness memory and how memories differ amongst individuals. While the rest of the group is minding their own business (i.e.

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.

In this activity, learners use sieves with different-sized holes to sort balls by size.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

In this chemistry demonstration, acid rain is simulated in a petri dish.

Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause
