Mold Terrarium: What Grows on Leftover Food?
Source Institutions
This activity shows you how to make a mold terrarium using a jar and leftover food.

Plant Parts You Eat
Source Institutions
In this food science activity, learners observe different plant-originated foods.

Food Chains and Webs
Source Institutions
In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

Food Chain Game
Source Institutions
In this outdoor game, learners role play populations linked in a food chain.

Energy Sources
Source Institutions
In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

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

Energy For Life
Source Institutions
In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

Got Seaweed?
Source Institutions
In this activity, learners examine the properties of different seaweeds, investigate what happens when powdered seaweed (alginate) is added to water, and learn about food products made with seaweed.

For the Birds
Source Institutions
In this outdoor activity, learners turn the fun of feeding wild birds into an investigation of bird behavior.

Flocking for Food
Source Institutions
In this outdoor beach activity, learners use a variety of "beaks" (such as trowels, spoons or sticks) to hunt for organisms that shore birds might eat.

Fuel for Living Things
Source Institutions
In this activity, learners observe what happens when yeast cells are provided with a source of food (sugar). Red cabbage "juice" will serve as an indicator for the presence of carbon dioxide.

Deer Me: A Predator/Prey Simulation
Source Institutions
In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.

Clipbirds
Source Institutions
In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

Population Game
Source Institutions
In this outdoor game, learners simulate a herd of deer trying to survive in an area called the "home range." Learners explore the concept of "carrying capacity"—what size population of an organism can

Sustainable Grazing
Source Institutions
In this activity, learners investigate the food, water, and space needs of common livestock animals.

Composting Bioreactor
Source Institutions
In this activity (page 19 of the PDF) learners will create a soda bottle bioreactor by exploring the science of composting, comparing variables such as reactor design, moisture content, and nutrient r

Web of Life Game
Source Institutions
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.
Pesticide Watch Card
Source Institutions
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

Starting Your Container Garden
Source Institutions
This guide outlines how to plant a garden even if you don't have a yard!

Junk-in-the-Box
Source Institutions
In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.
