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

In this activity, learners explore how engineers have developed sorting systems which integrate into manufacturing and packaging processes. Learners explore how coins are made.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this activity, learners explore how engineers work to solve the challenges of a society, such as efficient planting and harvesting.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners explore surgical instrument design. Teams of learners construct surgical instruments from everyday materials.

Learners examine the manufacturing process while they make picture frames from cereal boxes.

In this activity, learners explore how rescue devices are designed to aid professionals during emergency situations.

In this activity, learners explore how parachutes are used to slow down moving objects. Learners work in teams of "engineers" to design and build their own parachutes out of everyday items.

In this activity, learners explore the design of rubber band powered cars. Learners work in teams of "engineers" to design and build their own rubber band cars out of everyday items.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

Learners create an electrical-circuit maze out of wire, then try to pass a paperclip through the maze without touching the wire.

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land.

This activity (on page 2 of the PDF under SciGirls Activity: Lift Off) is a full inquiry investigation into the engineering challenges of sending scientific sensors into space.
