GEMS is a leading resource for innovative science and mathematics education. Developed at the Lawrence Hall of Science, the public science education center at the University of California at Berkeley, and tested in thousands of classrooms nationwide, over 70 GEMS Teacher’s Guides and Handbooks offer a wide range of supplementary learning experiences for preschool through 8th grade.

GEMS activities engage students in direct experience and experimentation to introduce essential standards-based principles and concepts. Clear step-by-step instructions enable all teachers to be successful presenting the activities. GEMS units offer effective, practical, economical, and schedule-friendly ways to provide high-quality science and math learning to all students.
