In this activity, learners work in groups to match craft sticks that represent chromosomes. Learners must define critical attributes of their chromosomes as they look for matching chromosomes. When...

Learners work in groups to design and build a tower out of balsa wood. As a motivator, they can compete to build a tower with the highest strength-to-weight ratio. Learners draw structurally sound...

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York. Next, learners design and build a 3D scale model of a shipping...

In this activity, dry ice and other items are used to construct a demonstration model of a comet that illustrates the comet nucleus, coma, and tails. This activity introduces learners to the...

Learners work in pairs to create three simple types of bridges, a beam bridge, an arch bridge, and a suspension bridge. They will observe how the bridges work under load and discover why engineers...

In this math lesson, learners determine and compare the rate of descent of various learner-constructed parachutes. Learners construct parachutes that will have maximum hang times. Learners then...

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land. Learners follow the engineering design process to design and build a...

In this activity, learners investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up. Learners connect their experience with cylinders to the world outside the...
