Problem Solving for General Chemistry
http://www.chem.purdue.edu/gchelp/
Discussess techniques for solving problems in the topics of Chemical Equilibrium, Kinetics, Solutions, Electrochemistry, Nuclear Chemistry, Thermodynamics etc..
Has static & dynamic past papers (including answers). A resource well suited for A’level chemistry students.
Matter Initiative for Schools
http://schools.matter.org.uk/Default.htm
MATTER Initiative for Schools website contains interactive resources (such as simulations, interactive exercises, experiments, tasks, etc.) designed to assist teachers and students of physical sciences at both 11-16 and A-level.

A sourcebook for teachers of Physics contains ideas of how to demostrate concepts in the topics of Motion, Heat, Sound, Electricity, Magnetism and Light.
In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds.* – Albert Einstein
Physics Applets and Shockwave Animations
A very good list of websites with Physics animations for diffrent topics. In fact, a one-stop centre.

PhysicsLab
This site offers free programs that are about serious physics of up to A and A S level or College standard. They are experiments you can do with your mouse.
The Doppler effect is a phenomenon related to the movement.The percieved sound has a different frequency from that emitted.
You can listen to the apparent frequecies.
The following well-known experiments serve as a motivation for studying quantum theory.
Very good simulations for Blackboday Radiation, Photoelectric effect and Compton effect.
The experimental results cannot be explained using ideas from classical physics
