Middle Grade Science CBL2/TI73

This book contains 21 activities for middle-grades science investigations that provide hands-on data collection in the physical, life, and earth/space sciences.

This 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.
