This activity (on page 2 of the PDF under SciGirls Activity: Hovercraft) is a full inquiry investigation into hovercraft engineering and design optimization.

This event guide features three related explorations in which learners investigate the following science concepts: how you design and build a structure helps determine how strong it will be; different

In this activity, learners explore how engineers have developed big wheels or Ferris wheels.

In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.

In this activity, learners use ABS pipe and an air leaf blower to make a strong shooting machine.

In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.

In this activity learners will build structures out of blocks and then roll balls to try to knock them down.

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

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.

In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

In this engineering activity, young learners investigate multi-level buildings.

In this activity, learners build their own construction cranes using tongue depressors and pushpins.

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 engineering activity (page 2 of PDF), young learners investigate how a wide base can make a building more stable. Learners use blocks or boxes of different sizes to construct stable towers.

In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

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