Best Free Engineering Lessons and Activities

Examine these top engineering lessons and activities for grades K-12. Take a look around. What do you notice?

Computers, phones, desks, and lights, perhaps. Chairs, backpacks, and textbooks are all possibilities. Walls and windows are most likely. Perhaps a parking lot with cars.

We are surrounded by engineering products. Every man-made object, no matter how small or common, contains the engineering design process from beginning to end. Engineering, which accounts for the “E” in STEM, is a necessary but largely unseen aspect of human existence.
