Green Chemistry
The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.
Wind Wise Education
What is the Cost of Inefficiency?
What does it cost to keep the lights on? Through a hands-on activity, class members use a watt meter and determine the amount of energy different types of light bulbs use. The class then determines the financial and environmental...
