Printed on 28x40cm card-stock in full color, these cycles include a control, a mute chart and all the movable pieces. With these charts you will be able to show the children how the natural cycles interact with each other and how man's presence on the earth has affected them.
They make an excellent supplement to the Impressionistic Geography Charts (Functional Geography curriculum ELC-5083 and ELC-5084).
This set includes the following charts:
· The Carbon/Oxygen Cycle
· The Nitrogen Cycle
- The Rock Cycle (chart only)
- Layers of the Ocean (chart only)
- The Water Cycle
- The Normal Greenhouse Gas Function, and
- Man-made Greenhouse Gases and their role.
These charts are included in our Studies in Ecology Curriculum (ELC-4049). Use them as an introduction to the earth cycles or let them be a stepping stone for your advanced students as they explore such concepts as Nitrogen Fixation and Photosynthesis.
