Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Salt 'n Lighter
Source Institutions
In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.
An Apple as Planet Earth
Source Institutions
In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.
Effect of Environment on Plant Growth
Source Institutions
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.
Common Scents
Source Institutions
Learners use a mortar and pestle to extract clove oil from cloves using denatured alcohol. They put this oil on paper, which they can take home.
Foam Peanuts
Source Institutions
Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.
Solar Energy
Source Institutions
In this activity (page 11 of PDF), learners compare the air pressure within a dark and a light bottle both heated by the sun, and discover that solar energy can be collected and stored in many ways
Low-Tech Water Filter for High-Impact Clean
Source Institutions
In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.
Recycling Rules: Understanding Recycling and a MRF
Source Institutions
In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
Sand, Plants and Pants
Source Institutions
In this activity, learners explore how the application of nano-sized particles or coatings can change a bigger material’s properties.
I Can't Take the Pressure!
Learners develop an understanding of air pressure in two different activities.
