The Amazonia Habitat is an exhibit from the National Zoo which highlights various aspects of the Amazon including habitat species, plant information, and more. The exhibit includes a virtual tour and an audio tour along with links to additional information.

In this Fizzy's Lunch Lab video, the kids are playing a baseball game but they need energy, so the Professor calls time to give them a quick snack of nuts and explains that nuts are full of protein and good fats, and give you enough energy to play a whole baseball game. [4:09]

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

In this interactive activity from Shedd Aquarium, build a fish and then release it into the reef to search for food and evade predators. Try different combinations and observe how each kind of fish has unique adaptations that help it survive in its habitat.

What are the state symbols of Colorado? Find them here, along with the date of their adoption, and links to pictures and more information.

This lesson introduces students to the idea of biomimicry or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.

While the creation of a dam provides many benefits, it can have negative impacts on local ecosystems. Students learn about the major environmental impacts of dams and the engineering solutions used to address them.

In this Fizzy's Lunch Lab video, the food group sings about why nuts are important to eat, and students learn that they contain protein and good fats to give them lots of energy for the day. [1:31]

This site has a colorful display of information about Oregon. It contains a map, pictures, a list of state symbols, and links to related information.

Introduction to the characteristics found in different animals and using the book: Feathers and hair, what animals wearAuthor:Jennifer Ward; Jing Jing Tsong

Students further their understanding of the salmon life cycle and the human structures and actions that aid in the migration of fish around hydroelectric dams by playing an animated PowerPoint game involving a fish that must climb a fish ladder to get over a dam. They first brainstorm their own ideas, and then learn about existing ways engineers have made dams "friendlier" to migrating fish, before being quizzed as part of the game.

This is a unit for K-2 students on fish habitats. The last day is a field trip to a local lake.

In this video segment from Evolution: "Great Transformations," paleontologist Jenny Clack explains that vertebrates evolved fingers before they invaded land.

See how Mississippi high school students confront the uncertainty and untidiness of science and develop problem-solving strategies in the context of local catfish farming. [5:40]
