STC Elementary Units & Refurbishments Sets

The STC™ (Science and Technology Concepts™) Elementary Kits for Grade K use inquiry-based hands on learning to create a cohesive framework of scientific and engineering practices to achieve scientific literacy. Many of the kits contain enough materials to teach the unit twice. Units can also be reused by purchasing the refurbishment set instead of purchasing a complete new kit.
