TeachEngineering.org has a searchable, digital library collection of standards-based engineering resources for use by K-12 teachers to help make STEM come alive. The resources include a broad range of curricula, multi-week units, lessons plans, activities and living labs. A unique feature is the Maker Challenges – teacher-prompted, open-ended project ideas and problems for students to solve in a self-directed, thinking-with-their-hands way, guided by the engineering design process.
Initiated by the merging of K-12 engineering curricula created by four universities, the collection continues to grow and evolve over time with new additions from other universities, and input from teachers who use the curricula in their classrooms.
