In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

Learners build structures from spaghetti and marshmallows to determine which structures are able to handle the greatest load.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

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

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

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 dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

In this activity on page 7 of the PDF, learners explore how engineers characterize building materials.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

Learners develop an understanding of air pressure in two different activities.
