In this chemistry activity, learners will separate a mixture of FD&C dyes (colors certified and allowed by the US for the Food, Pharmaceutical, Cosmetics & Personal Care industry) to practice

In this food science activity, learners explore digestion and proteins by observing the action of meat tenderizer on luncheon meat.

In this activity, learners construct possible food webs for six different ecosystems as they learn about the roles of different kinds of living organisms.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

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?

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.

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.

In this activity, learners use Jell-O to explore lenses. Learners cut Jell-O into convex and concave lens shapes and examine how light exits each lens in a darkened room.
