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

In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

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.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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 carefully look at four known household crystals.

In this activity, learners use things from the kitchen as building materials to explore how shapes contribute to the strength of different structures.

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.

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

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

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

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

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.

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

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