In this simple exploratory activity (1st activity on the page), blindfolded learners try to identify mystery items by smell.

In this activity about olfaction (7th activity on the page), learners use natural ingredients to concoct their own perfume.

In this matching activity (3rd activity on the page), learners use their sense of smell to match pairs of opaque containers filled with various smelly items like orange peel, roses, or moth balls.

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

In this activity, learners will explore nature by creating food for birds. Learners will develop fine motor skills and engage in nature observation through this activity.

In this activity (4th activity on the page), learners use their sense of smell to rate and arrange containers filled with different dilutions of a scent (like cologne or fruit juice) in order from wea

Using a milk-based recipe, learners create "moo glue" which is basically white school-type glue. The "secret ingredient" in milk that helps make glue is a chemical called casein.

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

In this activity learners observe mold growth on different types of bread by measuring and recording the growth rate.

In this math activity (Page 11 of the Dining Out! PDF), younger learners count out the total amount of money needed to purchase trail mix using the fewest number of bills/coins possible.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

This game teaches ratio and proportion by having learners make "salads" that combine three types of beans in different combinations.

In this activity, learners learn about the adaptations that flowers have developed which support pollination. Learners also list their personal preferences (i.e.

In this activity, learners explore the engineering design process (EDP)—the process engineers use to solve design challenges.

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

In this math activity (Page 8 of the Dining Out! PDF), younger learners select items from a menu and count out the total amount needed using the fewest bills and coins possible.

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

In this activity, learners make self-assembled polymer spheres.

In this activity, learners explore engineering package designs that meet the needs of safely shipping a product.

In this activity, learners add objects and substances to carbonated water to discover that added objects increase the rate at which dissolved gas comes out of solution.
