Detailed site, lots of pictures, and easy to understand descriptions of the phylum known as Porifera. This one is a winner!
A site from the University of California-Berkeley that details the process by which scorpions have evolved. Includes identifying characteristics of modern-day scorpions.
Evidence from the fossil record is used to support bird evolution from small carnivorous dinosaurs. In the student module, feathers, behavior, and skeletal structure are examined in an interactive lesson designed to impart a complete understanding of fossil bird evolution. In the teacher module, lesson plans, rubrics, assessments and references are clearly outlined.
A brief overview and links to more detailed information about the Miocene Era, as well as an interactive table of the subdivisions of this Epoch.
Biographical profile of Thomas Henry Huxley's life and work.
A good review of the natural history of the extinct species, the Sabertooth. Includes pictures of bones of this animal.
Berkeley offers a brief introduction to these Sphenophyta. At the bottom of the page, you can go to sections such as fossil record, ecology/history and systematics.
This extensive look at the arthropod provides enough information for any budding naturalist, but will also be interesting to one casually interested in insects, spiders, and crustaceans. The pictures are outstanding, and the writing is accessible and fun to read. Several interactive activities hold the reader's interest throughout the site.
Evolution can be supported by the lines of evidence which are presented in this resource. Recognize these lines: fossil evidence, homologies, distribution in time and space, and evidence by example.
A slideshow for teachers and students exploring Earth's geologic timeline and history. Click the buttons at left to select the teacher or student version.
A simple lesson where each group of students turns over word cards creating sentences from them. As the student turns over more cards, the group modifies the meaning of the sentence, leading them to discuss how scientists change their theories based on new information.
In this tutorial students can learn the definition of species, how new species evolve, and the processes that can cause new species to arise. At the end of the tutorial students can take a quiz to evaluate what they learned about speciation.
This site presents and defines the general parts of a research paper: title, abstract, introduction, material and methods, results, discussion, acknowledgments, and literature cited. Several helpful questions are presented to the reader throughout the site.
The Museum of Pealeontology at Berkeley offers an online geological time machine which allows you to catch a glimpse of ancient eras in earth's history. Click into an "Era" to learn about its stratigraphy, life forms, localities, and tectonics.
Complete biographical information with links to his theories. Contains links to interactives on plate tectonics.
What is evolution? This thorough site provides the basics of evolution focusing on the history of life, processes of evolution, microevolution, macroevolution, and more.
This UC Berkeley site extensively covers the death of the dinosaurs. It includes history, theories, invalid hypotheses, and current arguments.
A very good explanation of the scientific process and the differences between science and non-science. This is a concise and clearly written description.
