All organisms live in ecosystems where they depend on each other and the natural resources of the environment.  Learn how living and non-living things interact, survive, and change over time.

This video segment from Wild Europe: "Wild Arctic" explores the struggle for survival in one of Earth's most extreme environments.

This video segment from NOVA: A Desert Place describes the physical characteristics and organisms that define the desert biome.

Students will demonstrate their comprehension of primary and secondary succession by illustration succession in a chosen biome. This will be accomplished through notes and an activity.

This activity involves student research on the Internet to create a PowerPoint presentation showing the various parts that make up a biome (abiotic & biotic factors).

In this lesson designed to enhance literacy skills, students learn about the unique environment of southern Florida's Everglades and gain insights into the interrelatedness of living things, nonliving things, and climate.

Students use an inquiry approach to describe the major biomes of Minnesota before taking a look at adaptations that make organisms successful in their environments.

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents possesses, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents possesses. These physical features are then compared to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?
