Wednesday, April 22nd, is Earth Day. We have two great activities to help students appreciate the beauty and fragility of where we live.
The Blue Marble - Students compare maps with this famous photo and check to see which characteristics are maintained in each sort of mapping (Mercator, Goode homolosine, Gall–Peters, Winkel tripel) and which characteristics are distorted.
Start your class with a wonderful movie (produced by the Overview Institute) that shows the Earth as it was seen for the first time from space and the impact of that view.
Cost of light bulbs - Students learn more about LED and CFL light bulbs as they analyze and graph their energy use and costs of lights and appliances. Students use decimals operations, order of operations, graphing, systems and piecewise functions in this activity to help them think about ways to conserve the energy that they use.
