All the basic subfields are covered: electromagnetism, acoustics, optics, weather, nuclear physics, etc., plus chaos and string theory, philosophy, and puzzles. | Chemistry - Find a wealth of student basics like the periodic table of elements and worked chemistry problems. Also find hobbyist projects like invisible ink, fake blood and a home-made lava lamp. From the basics to advanced topics, this is the place to start looking for chemistry. | Geology - Science and technology of the earth itself is the topic of this site that includes the basics for students, information on topics of general interest like earthquakes, fossils and climate change, news about geology and many photos and quizzes. | Science, Optics and You - An interesting site with many educational and fun pages, including student activities and teacher resources.
