Here are some good informational sites for the main subject areas of school science. Use these as an aid if you need more science background, or as a refresher before you teach a particular unit.
Academic Resources.Net: Online Research and Referencehttp://www.academicresources.net/
This site provides numerous links to information dealing with general science, biology, chemistry, physics, genetics, laser science, nanobiology, nanotechnology, agricultural research, artificial intelligence, and robotics.
Biology Online: Information in the Life Scienceshttp://biology-online.org/
This highly useful site provides a dictionary of biology, including thousands of terms, that can be navigated using a searching tool. There are also biology tutorials focusing on various aspects of biology including adaptation, cell biology, developmental biology, freshwater ecology, genetics and evolution, neurology, regulations in biological systems, and origins and evolution of life. Links to a number of other earth and life sciences sites are also provided.
The Biology Project: An Online Interactive Resource for Learning Biologyhttp://www.biology.arizona.edu/
An excellent resource! An easily navigated site that provides useful tutorials and problem sets for biochemistry, cell biology, chemicals and human health, developmental biology, human biology, immunology, Mendelian genetics, and molecular biology. Chemistry reviews and tutorials are also available on the site.
Cell Biologyhttp://www.geocities.com/bunni20004/CellBiology
Created by kids for kids, this site provides an introduction to cell structure and types. A great resource for students.
Cellupediahttp://library.thinkquest.org/C004535/
This site provides an introduction to the intricacies of cells and cell biology. Users have the option of exploring the site on their own to gather information or being led through the site on a "guided tour." Discussion boards and "cell simulation" are other highlights of the site. May be useful for both teachers and students.
DNA from the Beginninghttp://www.dnaftb.org/
This engaging site can be used by both students and teachers to gain information about DNA, genetics, and molecular biology. Animation, image galleries, and videos help demonstrate the concepts.
Genetics Science Learning Center: The Basics and Beyondhttp://gslc.genetics.utah.edu/units/basics/
This site uses a multimedia approach to explain genetic concepts and how they relate to our lives. You can take an animated tour to learn about concepts such as chromosomes or mitosis, and you can "build" a DNA molecule. The site can be used by students, but it also includes teacher resources.
MIT Biology Hypertextbookhttp://web.mit.edu/esgbio/www/7001main.html
This online biology textbook from MIT covers a wide range of biology topics. It includes practice problems, quizzes, and a search engine for the site.
National Science Teachers Associationhttp://www.nsta.org/
This site provides a multitude of teacher resources for science education at the elementary, middle, high school, and college levels. It includes teacher interaction and discussion boards where teachers can aid each other in learning about and teaching various science topics.
Online Biology Bookhttp://www.emc.maricopa.edu/faculty/farabee/BIOBK/BioBookTOC.html
Filled with information, this site is like a textbook online, complete with charts, tables, and graphics. It includes an extensive glossary, review questions, and links to science websites.
