This program was first produced in the 1970's. We think you will find this new version even more powerful than it was in its original format. The four programs included on one-video cassette can provide the basis for many creative units in junior high school science and humanities. Earth is a minicourse in geology and ecology. Students will learn how the earth has changed over the ages from volcanism, mountain-building, erosion and plate tectonics.
Fire is a minicourse in energy.
Students will learn of the role fire plays in chemistry, in industry and inside our own bodies. Water is a minicourse on the fluid that supports all life while acting as the earth's thermostat and circulatory system. Customers who have an earlier version, either filmstrip or video, may buy this remade version at half price. See order form for details. Elementary, Jr. High, Secondary.
