Astrobiology - The Living Universe

Astrobiology: The Living Universe is a comprehensive and educational guide to life on Earth and beyond. Astrobiology is a relatively new field of science that covers a wide range of topics. This site features sections on the chemical origin of life, evolution, planetary biology, the search for extra-terrestrial life, supporting humans in space and exobiology. Concepts presented in textual format are reinforced visually with images, diagrams, animations and interactive simulations in order to facilitate understanding and retention of knowledge. Features such as print-friendly texts, PDFs, worksheets, quizzes and a virtual classroom make this site ideal for implementation in schools. Astrobiology: The Living Universe encourages readers to learn about the remarkable phenomenon called life and to be open to the possibility that living organisms may not be unique to the planet Earth.

Creation vs Evolution II

Creation vs. Evolution II is an educational web site designed to help middle and high school-aged students develop critical thinking skills by participating in a debate about a controversial subject. The site has sections where students can research creation or evolution, then participate in an online debate in several formats. In the course of debating the subject, the students will be drawn into studying molecular biology, comparative zoology, paleontology, geology, theology, and the scientific method. This is our second year of developing this site. In the past year, we were hard pressed to keep up with the volume of messages and poll results we received, but in the process, we learned how our visitors were using the site and what improvements they wanted. For example, we know that individuals, and sometimes entire schools, were using the site to research the subjects of creation and evolution for school reports. For them, we added many new articles and a search engine. We also know that the message board was a popular feature, so we added several new ways to debate and share ideas. Finally, we know that not everyone visiting the site agreed with everything we had to say on the subject, so we went back and edited the existing sections to make them more fair and accurate. We even added a third team member with a strong pro-evolution stance to balance the coverage.
