This new book takes a comprehensive look at science in the middle grades
through data collection with the CBL 2. Physical science is explored through
properties of matter, motion and force, and transfer of energy. Life Science
activities investigate living systems, populations and ecosystems, and
diversity and adaptations of organisms. Finally, students venture out into Earth and the Solar Systems through
the study of Earth and Space Sciences.
