Nova's video Earth from Space - 2 hours

Nova's Earth from Space

This is a must-see video for grades 3-12. It shows images of Earth from Space through 7 different spectrums of light, each one revealing astonishing truths about the condition of the Earth. This is a perfect lead-in to Ecology lessons because it shows the "big picture". It helps students to draw some important conclusions that will inspire interest, concern and hopefully, activism for the environment.
