Carolina Biological Supply, 1996.
Students learn about topics in the life, earth, and physical sciences.
The technological applications of science and the interactions among science, technology, and society are addressed throughout the program. The STC units, each of which takes about 16 class sessions to complete, encourage participatory learning and the integration of science with mathematics, language arts, social studies, and art. The components of an STC unit are a teacher's guide, a student activity book with simple instructions and illustrations, and a kit of materials. After studying the 2 separate ecosystems, students connect them and observe the ecocolumn, noting any changes that may indicate an imbalance in the system. They read about aquatic and terrestrial organisms and pollution.
