GCF Learn   Goodwill Community Foundation provides a site to learn  free consumer math, life skills, and computer skills.  We've looked through the computer skills (Computer Basics, Word, Excel, etc.) and found them thorough.  There are different options for the courses--you can either go through the self tutorial (which provides tests) or sign up for one of their online seminars taught by an instructor in the field.

The Electronics Club is a GREAT site for learning basic electronics theory and skills such as identifying components, soldering, reading a circuit diagram, and more.  Lots of information, projects to do, and useful links!
Enature. A great site to find out what that creature or plant is in your back yard! From birds, to fish, to amphibians to shells to insects to wildflowers. It offers online field guides with input
help and even specific species for your location! There's even bird songs. Great nature resource for bird, plant or critter identification.
Gamequarium is a site with links to educational games and videos to access online.  Many games are represented across all subjects, mostly aimed at the elementary ages, but some high school subjects as well. School House Rock Videos, The Magic School Bus, and Bill Nye the Science Guy are included in the multi-linked repetroire.
Home Science Tools. Home Science Tools (formerly Home Training Tools) is a science supplies company. Has actual kits and/or printouts of materials needed for Apologia, Abeka and Bob Jones science as well as a host of the usual and unusual science supplies. HTT also provides an interesting free, monthly newsletter (upon sign up), that includes science lessons and information resources.
How Everyday Things Are Made - "If you've ever wondered how things are made (candy, cars, airplanes, or bottles) or you're interested in manufacturing processes (forging, casting, or injection molding), then you've come to the right place. This introductory website for kids and adults shows how 40 different products are made and includes almost 4 hours of video. Think of it as your own private online factory tour. The Alliance for Innovative Manufacturing (AIM) a cooperative venture among Stanford University's Graduate School of Business, School of Engineering, and member industrial firms. Optimized for high speed internet access. Requires Flash." Really cool site!!
JETS  Junior Engineer Technical Society's site to promote and encourage students to consider engineering and technical careers.  The provides information, resources, and online challenges for the budding engineering student.
Master Books. This publisher specializes in Christian perspective science reference materials: i.e. encyclopedia style and story style informational books that cover the areas of: Weather, Geology, Astronomy, Human Anatomy, World of Chemistry, World of Medicine, Planet Earth (with explorers), and Dinosaurs, among others. There are also downloadable study guides for a number of the books. Fabulous books! Great Site. Great links on it to other creation sites.
Molecular Expressions  This is a site containing "photo galleries that explore the fascinating world of optical microscopy... going where no microscope has gone before by offering one of the Web's largest collections of color photographs taken through an optical microscope (commonly referred to as "photo-micro-graphs").  Great slide photographs for those who do not have a good microscope to use in science (most student microscopes offer poor results). The pond scum gallery has video streams of microscopic pond life slides--really helpful if your biology lab's pond sample didn't yield much!  Full descriptions included with each video or slide photograph.  Use the "Real Player" option for best results (you will need to download Real Player if you don't have it on your computer).
My CAD site provides over 40 free tutorials to learn AutoCad (you will have to have AutoCad software installed on your computer).  It looks to be a good introduction to AutoCad for budding engineers. Lessons can also be purchased on cdrom for a low fee.  Provides link for a free trial of AutoCad software or go to Computer Products for Education to get a student version for a fraction of the cost (homeschoolers are eligible with verification).
National Parks Web Rangers provides games and online interaction for our nation's national parks regarding nature, science and history.  For all ages and levels of difficulties.
Neuroscience for Kids  From their website "Discover the exciting world of the brain, spinal cord, neurons and the senses. Use the experiments, activities and games to help you learn about the nervous system. There are plenty of links to other web sites for you to explore."  The lesson plans we viewed appeared to be geared towards the elementary age student.

Online Dissection Labs:Here's a good site for online lab links for those who would like help with their dissection or would like to view a dissection without the mess. Includes frog, cow eye, sheep brain, heart, plant cells, cat and earthworm etc.  Here is also a frog dissection worksheet.

Periodic Table. Los Alamos Lab provides an interactive periodic table that is both informative and fascinating.
Periodic Table by Elements Database has an interactive element chart, a hangman game to learn elements, an element quiz, and a printable periodic table. 
The Physics Classroom  This site provides help for the high school physics student.  It includes the Physics Tutorial (Learn basic physics concepts and review them in the Physics Tutorial. Check Your Understanding quizzes let you know you got it.), the Multimedia Physics Studio (Is physics difficult for you to visualize? Do you need to see it to understand it? Then visit the Multimedia Physics Studio.), and the Physics Help (Practice your skills in Physics Help. Hone your skills by graphing problems, recognizing forces, identifying vector magnitude and direction, and practice vector addition.). Secular site.
TryEngineering  This site is a resource for students (8-18), their parents, and teachers.  It gives information about engineering careers, associations, colleges, AND lesson plans and games to help get your budding engineer started!
 Scratch  Scratch is a new programming language that makes it easy to create your own interactive stories, animations, games, music, and art -- and share your creations on the web.  Scratch is designed to help young people (ages 8 and up) develop 21st century learning skills. As they create Scratch projects, young people learn important mathematical and computational ideas, while also gaining a deeper understanding of the process of design.
Scratch is downloadable from the site free of charge, and the Scratch site offers supports for students and educators.  Currently available for Mac OSX and Windows (Linnux available soon).

Sparkfun Electronics  is a company that likes to share, enable, and have fun with electronics.

Super Charged Science is the brain child of scientist Aurora Lipper, a former NASA engineer and Cal-Poly instructor who has a deep love of science and vision to help parents encourage that love in children.  She has created numerous science experiments which can be downloaded online and duplicated at home.  She offers a free manual and weekly experiment newsletter as well. Experiments are at various levels, k-12. We've not tried any of the free stuff, but they look promising. (Materials appear to be from a secular basis.)
Quick Study Labs  This site provides an online electronics course for homeschooled students, electronics summer clubs, and some cool links.  Currently, courses are about $110 ($55 for lab equipment--which is reusable for other courses, $55 course registration).  There are several courses, the Edison project for students ages 8-11, and Electronics I and II for students ages12-18.   Electronics I and II constitute 1 semester credit of science.  Taught by an enthusiastic community college electronics teacher who desires to bless the homeschool community. 

Virtual Science. A page full of science links including virtual caves, virtual labs, virtually EVERYTHING!  We have NOT gone through a lot of these links nor reviewed the info as there is SO much stuff, so please be careful, but there is a lot of interesting looking links there!
