Grades 4-7 (DVD 17 min.)

Have you heard of hydroponics or aquaculture? In this program, you get a fish-eye view of fish and lettuce production in an ecologically-closed system. We look at plant and fish life cycles, showing how each is dependent upon the other for nourishment. Concepts of symbiotic life systems, chemical and nutrient cycling, and integrated food production are highlighted. A "model ecosystem" can be used to demonstrate concepts, both in the program and the classroom.
