What are habitats? What are liquids? How do changes to Earth occur? Second graders discover the answers to these questions and more—as they sort the magnets in our hands-on center! The center includes a freestanding magnetic board and 63 color-coded magnets covering life, earth and physical science topics. Simply place the categories at the top of the board and invite students to sort the corresponding magnets under their proper headings! The magnetic board measures 14 1/4" x 16 1/2" and has science definitions and discussion prompts on back.
