Treehouses are Tree of Life pages designed for
k-16 learners, teachers and the young at heart. The information found on treehouses complements
the scientific core content presented on ToL branch pages, leaf pages,
other articles and notes. Our treehouse collection is growing and our goal is to have many treehouses sprinkled throughout the ToL. See About ToL Treehouses for more information, and Learning with the Tree of Life to get an overview of ToL learning resources.

Browse Sample Treehouses
- Where Bobcats Live
- Learn about where bobcats live in the desert near Tucson, Arizona, and why they sometimes move into human settlements. This page was created by a student at Catalina Foothills High School in Tucson, and features pictures of a bobcat in the author's backyard.
- Burrowing Owl Dispersal Movements in Tucson, Arizona
- Widely distributed throughout most of the western United States, Western Burrowing Owls are small, and they roost and nest in underground burrows in open grasslands and prairies, as well as other areas characterized by sparse vegetation. Due to noticeable population declines across most of its range, wildlife researchers are investigating potential causes for these declines and are focusing efforts to protect valuable habitat. This page was created by Lirain Urreiztieta, an employee of Arizona Game and Fish.
- The Galapagos Finches
- The Galapagos Finches are one of the most widely recognized examples of research in evolutionary biology. This treehouse provides access to a variety of data resources that can be used to think about the causes and relationships underlying the distribution and other characteristics of the Galapagos Finches. The materials featured on this page come from an NSF funded educational project called Beagle Investigation Returns with Darwinian Data (BIRDD).

- The Ninja Group Ecobottle Investigation
- Ecobottles are multi-environmental, closed habitats. They consist of 3 environments; terrestrial, decomposition, and aquatic. The point of the ecobottles was to see what happens in a closed environment; to see if organisms would be able to survive in a closed, previously uninhabited environment. If you are interested in learning a thing or two about this project, visit this treehouse. This treehouse is part of the City High School Ecobottle Investigations Portfolio.

fun and games
- Beetle Treehouse
- This treehouse isn't finished yet, but it will give you an hint about what one style of treehouse might be like.
- Frorio, the Fire Belly Toad Game
- This treehouse features the Fire Belly Toad game for all ages. Students created this game so that it is both fun to play and a learning experience. The game is a downloadable stand alone program for Windows only.
- Giants, Markets, and Pygmy Squids: A Game for All Ages

- The "Red" Green Algae: Watermelon Snow
- Although known for its bright pink-red color, watermelon snow, scientifically known as Chlamydomonas nivalis, is actually a species of green algae. Authored by a secondary school student at Havergal College in Ontario, Canada, who created her own clay models and word search games.
- The Sonoran Desert Endangered Species Card Game
- The Sonoran Desert Endangered Species Card Game teaches about the habitat, range and status of nine Sonoran Desert Endangered Species. This treehouse features materials from the Sonoran Desert Kids club, a ToL partner project.

art and culture
- Origami Organisms
Create origami birds, theropods, crocodiles, and dinosaurs. Learn about these organisms and how they are related.
- The Sea Star Song
- A song about sea stars written by secondary school students at Havergal College in Ontario, Canada.
- How to Make a Black Widow Spider Mobile
- An exercise meant to serve as a tool to help students learn about the Black Widow Spider. The activity provides information so students will have a basic understanding about where the Black Widow lives, what it eats, and how it interacts with other spiders. This craft is not only educational but fun to make as well!

- Introduction to Learning with the Tree of Life
- To learn with the Tree of Life (the ToL) and become a ToL contributor, it is important to first learn about the ToL. In this WebQuest you will play the role of students and/or biologists who have been invited to become contributors to the ToL and present at the ToL Biodiversity Conference in the Galapagos. In the process of exploring the ToL you will learn about different ToL page types, who authors ToL pages, how to browse the site and learn about phylogeny, and opportunities for contributing treehouses.

- City High School Ecobottle Investigations
- City High School 9th graders in Tucson, Arizona built ecobottles to explore ecosystems on a small scale. Each ecobottle contained three sections: a terrestrial section, an aquatic section and a decomposition section. Students devised plans for each section and researched the type of organisms they could add to each zone. The class agreed that they learned a lot in the process of creating "mini-worlds" and observing their development over the course of two months. The students' documentation of their work was an important part of the project, and provided the basis for the treehouse investigations that are part of this portfolio.
- Havergal College Student Treehouses
- Grade 11 Biology students at Havergal College, a secondary school for girls in Ontario, Canada, have created a wide variety of treehouses on organisms such as watermelon snow, black mambas, clownfish, ostriches, pacific treefrogs and more! We highly recommend checking out these fun, creative and educational story, game, art and culture and investigation treehouses. Havergal students are among the first to create treehouses on the Tree of Life and we applaud their efforts.

- Rutgers Preparatory Student Treehouses
- Rutgers Preparatory School is a coeducational independent school founded in 1766 and located in central New Jersey. The upper School has 325 students, all of whom take a biology course in their sophomore year. Biology begins with biodiversity, including an emphasis on evolutionary relationships and phylogenetics. As part of this unit, students write a creative short story or game from an organismís viewpoint. Creating treehouses on the Tree of Life gave students a unique opportunity to publish their work for a larger audience.
- Sonoran Desert Organism Investigations
