In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan. Learners will build a sturdy frame...

In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows. Participants then design and build their own models using the steps of the design process to...

In this engineering activity, young learners investigate multi-level buildings. Learners observe buildings in their neighborhood and then, using simple household materials, create their own multi...

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog...

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink? Learners must adjust many variables in their boat design to maximize...

In this design challenge activity, learners build a rubber band-powered rover that can scramble across the room. Learners follow the engineering design process to design and build a rover out of...

In this activity, learners construct paper airplanes that twist and turn. Learners can experiment with different designs and modifications to the gliders' flaps to adjust the aerodynamics and...

In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads. Extension...
