Thanks to the PTO's commitment to science education, students in 4th & 5th grade learn science through hands on experiments that reinforce state standards. El Granada uses the Full Option Science System (FOSS) curriculum developed by the Lawrence Hall of Science. All lessons are lab-based and actively engage students in scientific method and inquiry. For more information about FOSS, please visit: http://lawrencehallofscience.org/foss/index.html and http://www.fossweb.com/
