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?

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.

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.

In this bilingual (English/Spanish) activity, learners create family trees by tracing the hands of their family members.

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