Transforming Engineering Education for Middle Schools (TEEMS) is a free engineering curriculum for gr. 6-8 learners. TEEMS is based on theories of learning that encourage the use of story to promote engagement. The curriculum includes two 2-week engineering units on (1) the engineering design process and (2) materials and tools and six 1-4 day lessons that connect engineering to NGSS science topics of waves, matter and its interactions, body systems, Earth’s systems, Earth’s place in the universe, and evolution.
