In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

No glue is needed for learners of any age to become marshmallow architects or engineers.

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

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

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.

In this activity, learners examine baking powder, a combination of three powders: baking soda, cream of tartar, and cornstarch.

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

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