This scientific article provides anatomical features and the adaptive advantages of those features of owls and giraffes. The text is written for native speakers 9 years and up.

This article provides a detailed flowchart of the processes that help trees to survive the winter: 1 dropping leaves, 2. create anti-freeze, 3. produce buds. Photos and photo series support the scientific elaborations. The text is in scientific, child-friendly language for children 10 and up.

This scientific article iluminates with three different examples, how animals produce venom and for which reason: poison dart frogs absorbs it by feeding on venomous plants; spitting cobras produce their own venom within the system; puffer fishes probably eat bacteria that produce the venom. The text is written for native speakers 9 years and up.

This OLogy activity takes a look at some of the more amusing traits that are determined by genetics. Students answer four yes/no questions, and then compare their answers with others.

In this classroom activity, young students are introduced to sets and subsets. The activity opens with background information for teachers about cladistics. After brainstorming different ways to group the class itself, students work in small groups to identify subsets of coins. The groups then complete a worksheet that challenges them to group dinosaurs into sets and subsets and share their results with the class.

This expository article, written for students in grades 4-5, explains why ice floats and how this is essential to life on earth. Modified versions are available for younger students.

In this biodiversity activity, students learn how to construct their own cladogram. They consider four coins (quarter, dime, nickel, penny), identifying defining characteristics. Then, students construct a Venn diagram, followed by a cladogram. The two-page printable PDF includes tips for both teachers and students.

In this biodiversity activity, students learn how to construct their own dichotomous keys. They use either specimens they've collected or ones you bring into class, such as shells, fruit, or leaves. The one-page printable PDF includes guidelines about what students should look for and include when creating their dichotomous keys.

These two biodiversity exercises will help students become familiar with the methods of scientific research. The printable seven-page PDF guide includes Studying Biodiversity in Arizona, where students review a paper written by one of the museum's Young Naturalist Award winners and deconstruct her scientific investigation and Biodiversity in Our Own Backyards,where students use a Biodiversity Counts activity (included in the guide) to investigate the interaction of living things near where they live.

This activity is designed to be used with the online text and graphics that are part of the Transformation of the Biosphere Wall in the Hall of Biodiversity. The one-page printable PDF includes two student activities: a general investigation of a threat to the world's biodiversity and a specific investigation of the concrete way in which one of these threats has affected the U.S. environment.

This printable PDF map of the museum's Hall of Biodiversity identifies the eight key stops to hit during your visit, including a photograph of each.

This treasure-hunt activity is designed to be completed during a trip to the museum's Hall of Biodiversity. The printable one-page PDF challenges students to find 31 animals and plants in the Hall's diorama. Photographs of 21 of these specimens are included.

The museum's Milstein Family Hall of Ocean Life explores the diverse, complex web of life supported by the ocean and the vital inter-relationships between human and aquatic systems. This insert to the hall guide is designed to help you maximize your trip to the museum.

In this classroom activity, young students compare their feet to the foot of a large Apatosaur. The activity opens with background information for teachers about the enormous size range of dinosaurs. After using personal references to describe the size of dinosaurs, students examine the outline of an Apatosaur footprint. Students then estimate how many of their footprints would fit inside the Apatosaur footprint and conduct an experiment to test their estimate.
