The Elementary Science Program (ESP) Homepage is sponsored by BOCES, whose mission is to provide quality, cost-effective educational services in partnership with school districts and the community in a manner that supports excellence and equity for all learners. The site offers a number of good educational materials including the ESP Units, which contain links to over thirty subjects areas including buoyancy, light, forces in space, electrical circuits, magnets, powders and crystals, soil, sound, and weather. Each page then contains links to outside educational material and resources related to that category, making it a useful tool for locating a wide array of material on particular science subjects.
