In this activity about food safety and nutrition, learners investigate safe food preparation by making fruit ice cream.

In this nutrition activity, learners explore food labels and consider the nutritional value of foods. Learners also explore units of measurement commonly used on food labels.

In this food science activity, learners observe different plant-originated foods.

In this outdoor game, learners role play populations linked in a food chain.

Some animals can swallow food whole, but humans have to chew. In this activity, learners will investigate what saliva does chemically to food before we even swallow.

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 simulation, learners act out each digestive function of the organs, tissues, and cells in the digestive tract.

In this genetics activity, learners extract DNA from an onion, using detergent solution, a food processor, and rubbing alcohol. They will also discuss genetic engineering of plants.

In this game, learners each represent a different organism in an environment. They build a web during the activity, and discover how all the players in an ecosystem depend on each other.

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.

After learning that some of the chemicals we add to food crops may have harmful consequences on our health and the health of the environment, learners will create a pocket-sized card with their favori

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

In this activity and/or field trip, learners investigate the water currents that aquatic animals create when they breathe, feed, and propel themselves through water.

In this activity, learners of all ages will design a functional bird feeder using familiar, every day materials.

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

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 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 Energy and Environment activity (page 9 of the PDF), learners calculate the mass of a piece of gum, compare it to the mass of the gum's packaging, and then create a bar graph of the results.
