In this activity, learners play an active version of freeze tag based on predator/prey relationships.

In this activity, learners make a model of the solid Earth's layers that's good enough to eat! Learners use tasty foodstuffs to simulate Earth's inner core, outer core, mantle, and crust.

In this activity, learners create a map showing the origins of spices and herbs from a favorite recipe(s). Learners first research the origins of the ingredients and then locate them on a world map.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

Learners work as a group to create a map of their community. They use pasta to represent people, and glue the pasta on their maps to show areas of large population.

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

In this activity (page 7 of the PDF), learners will investigate the contents of owl pellets. Learners will discover how owls digest their food as well as the kind of animals they eat.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this genetics activity, learners discover how to extract DNA from green split peas.

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

In this chemistry activity (page 5 of the PDF), learners make an acid-base indicator using cabbage. Learners then explore how various subtances react with this indicator.

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

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

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 follow a recipe to create play dough scented with fruit-flavored drink mix.

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

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