In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners make their own edible DNA double helix out of candy and find out about the shape of DNA.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners eat a snack and make a model of the plumbing system of a volcano.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners model hot spot island formation, orientation and progression with condiments.

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

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

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 use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

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

In this activity, learners separate the components of Gatorade using a home-made affinity column.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

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