In this activity, learners make "solar cookies," edible models of the Sun's outer layers using sugar cookies and toppings.

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

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

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

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

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 work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

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

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

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this activity, learners construct a cereal chain as a model of how proteins are made in the cell.

In this activity, learners use three types of cheesy snacks--cheese balls, cheese puffs, and Cheetos--to learn about polymers.

In this yummy earth science activity (page 5 of the PDF), learners use fudge to learn about different kinds of lava.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

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.

This is a classic exercise for visualizing the scale of the Solar System.

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