Learning Equipment Supply Service (L.E.S.S.) offers school science lab equipment loans and associated technical support services for science teachers at needy public schools of Los Angeles. Part of our technical support involves re-organization, identification, and repair of forgotten or unknown lab equipment in teachers' science storage areas. Another part of our technical support involves showing science teachers how to use lab equipment in inquiry-oriented ways that support the alignment of existing or new lessons with the NGSS.
