PSRC Physical Sciences
Resource Center. It's aimed more at college
teaching, but it has a section on demonstrations and labs that might be
inspirational.
From Stargazer to Starships
A book-on-the-web about spaceflight, spacecraft, and orbital motion of the
earth, with digressions into Newton's Laws. By David P. Stern
Also available in Spanish , French and Italian
Ask AmyA review of websites
for children, emphasizing content. The
backissues archive is well worth browsing.
Physics toys that you can make
It's quite an amazing collection. Some require special materials (which are
offered for sale) or more than ordinary mechanical skills, but they are fun
to read about.
Sites-for-Teachers
Many pages of resources for teachers, ranked by "popularity."
Applets.
These are interactive demonstrations, in the form of
programs that run on your computer.
Kamikawa's applets
The Convex Lens, Rainbow, and Colors applets are particularly recommended.
Fu-Kwun Hwang's applets
Some of these are complicated, but correspondingly there is more to
learn. And there are lots of them! Click on the bar "light/optics"
and then choose one of the many applets on the list. Particularly
interesting are "reflection/refraction", "physics of rainbow",
"the world above the water surface", "The world through a hole",
and
"prism: reflection and refraction" -- and that's just from the
optics list!
Kiselev's applets
Check out the one called
"Image formation by a converging lens"
Optics examples
Pages that discuss particular issues relevant to optics.
A set of pages about colour
from the Australian Museum. Most of this
site deals with the wonderful plants and animals and people of
Australia, but this set of pages deals with the physics/psychological
concept of color.
3DLens.com A supplier of Fresnel lenses, polarizers, and other optical materials
Question and Answer pages
There are several sites that offer to
answer any questions sent in. The quality of the answers
are rather highly variable.
If you would like your question incompetently answered by a
Kentucky professor, you could send it to the
Question Board!
How Things Work
according to Professor Louis Bloomfield at the University of
Virginia. And he is quite generally right!
PhyslinkWhat we like
about this one is that several of the answers have corrections posted -- so
someone is paying attention to accuracy.
Ask-a-scientist
Answers to various physics questions, of somewhat variable quality
from Argonne National Laboratory.
Questions and answers on all sorts of science questions.
Unfortunately, no one checks the answers, and too many of them
are poorly presented, fail to answer the original question, or are
simply wrong.
