In this engineering activity, learners explore simple machines and then build cardboard automata using cams. Learners are also challenged to build a complex machine--a moving sculpture that tells a...

In this activity, learners construct bug models that "jitter" all over the table with just a battery, motor, and counterweight. Use this hands-on activity to facilitate inquiry and...

In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors. Next, they make draft stoppers to reduce air flow and...

In this activity, learners construct drawing machines using a cup, some markers, and a battery pack. The markers act as "legs" for the machine, making a drawing that records as it moves....

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment. Learners explore such concepts as material properties, varied shape strengths, center...

Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle. In this simulation activity, learners create a miniature wind tunnel test by blowing air with...

In this activity, learners build a carousel toy that spins when pushed down. Use this activity to demonstrate principles of motion including momentum, angular motion, linear motion, and cyclic...

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight. Learners are encouraged to work in groups or with their families to create...
