GCSE
This one is somewhat heavy on text, but is still an interactive textbook that higher GCSE & A-level students will find very useful.
This site contains good illustrations and suitable text to explain fractional distillation in depth. A very useful resource for GCSE student or A-level chemists.
Although primarily aimed at GCSE students, this site will be of use to students between the ages of fourteen and sixteen worldwide. It is clear from the first page that considerable thought has been put into making the site easy to navigate, and whilst the presentation is kept pleasingly simple, it is never simplistic. Touches such as the colour coding of key words, and the amusing explanation of why visitors should bother to acquaint themselves with the about this site page all serve to reinforce the excellent first impressions.
An essential resource for all GCSE students. The site includes revision pages on ecology, humans, inheritance, life processes & cells, plants and variation. These topics are followed by an interactive quiz. There is also a search engine with links to most GCSE subjects.
