As part of a hands-on-Science Program, Los Altos has implemented three science units (life, physical, earth) for use at each grade level, K–6. In grades K-5 teachers implement science lessons through the FOSS hands-on science program. In grade 6 students make use of the Prentice Hall science program that continues through the 8th grade. All teachers are invited to receive in-service training on the science kits, leadership training, summer institute training, and case study work. All schools have matched their programs to State science standards. Technology is infused into numerous lessons and lab settings. All schools use pair learning, group learning, computer assisted instruction, and cooperative learning to help each child succeed in science. Guided reading is also used to help children read for specific information. Most of the schools hold yearly science fairs. Teacher-made tests, observation scales, and science portfolios are used for student/program evaluation.
