Here Are Some Great Science Links!

Below are listed some of the sites that The Science Notebook staff has found useful in one way or another.Please bear in mind, however, that The Science Notebook has no control over any external link, and what is good today may be gone tomorrow.  If you find a link that no longer works, please contact us.  NOTE: All external links open in a new window.

Useful Links By Subject


NASA - The National Aeronautics and Space Administration maintains a wealth of information on astronomy and space exploration.  This information is actually spread over dozens of sites and includes NASA TV, multimedia, stunning photos and activities for children of all ages. It's a huge collection of information, so you might have to do several searches to find what you want. - This is a great way to keep up with space in the news. This is a commercial website with lots of content, but it is very well organized, and some of their slide shows are just outstanding!


Biology at - has a wealth of information written by outstanding teachers and/or experts in their field that provide lots of information for students and those who are just interested in the subject.  This, along with several other sites are given here just because they are so good!


Chemistry at - This site covers the fundamentals of chemistry and is certainly worth checking out if you are just getting started.  There are also some excellent experiments.

Chemistry at - This site also has a wealth of information on beginning chemistry as well as some great experiments to try.  Check them out!


Physics at - This is another of the educational sites that presents an excellent overview of the subject.  There are also some pretty neat experiments here as well.

Physics Lecture Demonstrations from the Department of Physics of University of California at Berkeley - this is a collection of physics experiments designed for teachers, but since they use simple equipment, many are also suitable for advanced students and experimenters.

Simple Machines - This is a contribution from thirteen year old Marcus who was inspired by his experience at a summer science camp to create a web page dealing with simple machines.

Earth Science

Geology at - Another of the sites.

USGS - The United State Geological Survey is the U.S. government agency responsible for the study of all things related to geology.  Just as with NASA above, and NOAA below, there is a wealth of information, and your biggest challenge may simply be to find what you need.  But the search is half the fun!


Weather at - What can we say other than some of the best teachers have collected some of the best information?

NOAA - Otherwise known as the National Oceanograhic and Atmospheric Administration, this is the agency responsible for public weather forecasting in the United States.  NOAA has many sites nationwide with a lot of material for both students and teachers, and this is the starting point for all that information.  Start by clicking on "NOAA Education."


Some Simple Electricity Experiments - These are from the "The Exploratorium Science Snacks" website.

Electric Math - This site was suggested by a Science Notebook user and explains some of the math and technical terms used in the study of everyday objects powered by electricity.

Lessons in Electric Circuits - This site contains a complete textbook covering basic electricity and electronics.  It is probably geared more toward older students.


Electronics For Kids - A nice collection of simple electronics experiments.

The American Radio Relay League - If you are interested in electronics as a hobby, you can't do better that amateur radio.  And the best place to learn about amateur radio in the U.S. is the ARRL website.

The TEARA-SCARS Volunteer Examiner Team - In the U.S., amateur radio exams are administered by accredited volunteer examiner teams. One such team, located in eastern North Carolina, has some great pages on the Triangle East Amateur Radio Association's new website.  And their "Links of Interest to All Hams" page is a great resources as well!

Electronics Tutorials - Here you will find a series of lessons on electricity and electronics that are geared toward preparing for for an amateur radio license.   The theory portion is applicable everywhere.


How Stuff Works - This is the absolute best site for anyone who wants to know how the items we use everyday works.  Browse and learn!

Morse Code and Radio for Kinds and Amateurs - The owner of this commercial site has gathered some excellent reources and information and resources aimed primarily at folks, but some of us "old timers" on the Science Notebook staff, thoroughly enjoyed them as well.

Just Learn Morse Code - Go to this link to get a free Morse code trainer that teaches you to receive Morse code by sound.  If you learn to receive it, you will have no problem sending it!

WD8LQB Learning Morse Code Podcast Podcasts - This series of free podcasts will take you through learning the code step by step!

Morse Cat
- Another good free Morse code trainer is found on this site.  This one features a kitty cat doing the sending!   The author's site is in German by default, but this link will take you to an English version.

G4FON Trainer - This free Morse code trainer will teach you how to receive Morse code via radio under realistic conditions.  Use one of the trainers to above to learn the code, and then "graduate" to this one.

WinMorse 2
- A free program that converts typed text into Morse code is available on this site.  It won't really help you learn all that much, but it will help you hear what the code is supposed to sound like.

SuperAldis - The free program on this site teaches you how to receive Morse code by flashing light.

Flags - The free program on this site will train you to recognize nautical flags once you have memorized them.

Semaphore flags information
- This Boy Scout site has lots of great information for anyone who wants to learn Semaphore signaling.

Lab Equipment

School Science Lessons - Queensland College - This site contains a wealth of experiments based on the 1979 edition of the "New UNESCO Source Book for Science Teaching."  For many years, this material has provided teachers and experimenters with instructions on how to make science equipment from common items.

UNESCO Guidebooks - This site, maintained by "International Council of Associations for Science Education" contains an archive of the UNESCO guidebooks on its old site.  Much of the content of the "School Science Lessons" site comes from these guides.  You can still download these guides in .pdf form, but since ICASE has moved to a new site,this link could go away at any time.  If you are a teacher or serious hobbyist, I strongly urge you to download this information while you can.

UNESCO Handbook - A pdf scan of the 1973 "New UNESCO Source Book for Science Teaching." is available here. This book contains much of the information found on the previous two sites, and is an excellent resource for the student or experimenter.

Fun Stuff

Science Paper Models - This site allows you to print out a variety of science related models and to then cut and glue them together.  Check out the sundial, globe and dinosaurs!  And if you enjoy this sort of thing, be sure to plug "paper models" into your favorite search engine.  There are tons of free paper models online.

The Science Toymaker Page
- quite a few neat projects, and most are very simple. I wish I'd thought of some of these.  Check it out!

Other Great Sites For Science Experiments and Activities

There are probably hundreds, if not thousands of sites like this online, but here are a few of the favorites of The Science Notebook staff.  

Bill Beatty's "Science Hobbyist" - This site has a little something for everybody.  You'll find all kinds of information for science projects appropriate for all ages.

Society for Amateur Scientists - There was a time when ordinary citizens could make significant contributions to science.  This group believes that time is now, and their membership is proving it.

Bizarre Stuff You Can Make In Your Kitchen - This site pays tribute to the science experiments and tricks of days gone by.  You can still do many of them, just like your parents (or grandparents) used to do when they were kids!
