This activity shows you how to make a mold terrarium using a jar and leftover food.

In this activity, learners play a game to simulate the food chain.

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

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

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

In this activity (page 5 of the PDF), learners will create a food web and explore food sources for different organisms. They will identify relationships between organisms in an ecosystem.

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.

In this activity, learners play an active version of freeze tag based on predator/prey relationships.

In this outdoor game, learners play the roles of gray or red squirrels gathering and storing a supply of food in "fall" and recovering enough of them to survive the "winter." Learners carry bags repre

This activity is on page 10 (continued on the right side of page 11) of the pdf, part of the Forest Animals Discovery Box. In this game, learners act out the food web.

In this outdoor activity, learners investigate ant behavior by testing ant feeding reactions to different types of food.

Birds' beaks are designed to allow birds to get the most of whatever food they need. In this activity, learners get an idea of how different beak shapes suit different food sources.

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 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.

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.

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

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.

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.

In this activity, groups of learners work together to create edible models of chemicals involved in autotrophic nutrition.

In this activity, learners will simulate the interactions between a predator population of gray wolves and a prey population of deer in a forest.
