In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this activity, learners create a sealed, mini ecosystem that supplies freshwater shrimp with food, oxygen, and waste processing for at least three months.

In this activity (on the left side of page 5, continued on the right side of page 4 of the PDF), learners make models of colorful butterflies.

In this hands-on activity, learners investigate the functional design of leaves on a tree.

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

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 (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 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 are divided into teams.

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

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

In this hands-on nature activity, learners observe the emergence of leaves and flowers. Branches from trees and bushes are collected in the early spring, brought indoors, and placed in water.
