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...

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 activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons. Learners can experiment with balloons of various sizes and shapes to change the...

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float. <br> Note:...

In this activity, learners build a hovercraft using a paper plate, cup, and simple motor. Learners follow simple instructions that include helpful photos to build a vehicle that glides over a...

In this activity, learners build a sled kite that models a type of airfoil called a parawing. Learners keep a journal on the behavior of the kite and test different variables (tail, tail length,...

In this team design challenge (page 19-24 of PDF), learners "land" a model Lunar Rover in a model Landing Pod (both previously built in activities #3 and #4 in PDF). Learners drop the...

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...
