Best Free Engineering Lessons and Activities

Explore these top engineering lessons and activities for K-12 classrooms.  Look around. What do you see? Perhaps computers, phones, desks, and lights. Possibly chairs, backpacks, and textbooks. Likely walls and windows. Maybe a parking lot with cars. Every human-made object, no matter how small or common, contains within it the engineering design process from start to finish. Accounting for the “E” in STEM, engineering is an essential but mostly unseen aspect of human existence.
