In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners make water rockets to explore Newton's Third Law of Motion. Learners make the rockets out of plastic bottles and use a bicycle pump to pump them with air.

In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.

In this activity, learners model directed evolution by making paper fly. Learners construct and fly paper airplanes.

In this activity, learners create painting machines that can paint moving forwards and backwards.

In this activity, learners are challenged to create a parachute using easily sourced materials in order to transport a LEGO figure safely to the ground.

In this activity, learners explore how engineers work in a team to solve problems.

Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.

In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

In this activity, learners are challenged to design a wind-powered car using only a handful of household materials.
