This hands-on activity shows you how to build basic architectural shapes out of toothpicks and gumdrops.

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

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

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

In this quick SciGirls activity (page 1 of the PDF under SciGirls Activity: Doghouse Design), learners will be introduced to the concept of thermal conductivity.

In this activity, learners transform everyday milk into small plastic figurines and jewelry. Use this activity to introduce learners to monomers and polymers.

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 activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

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