First I must say what a reasonable price policy this company has. For less than £7 you are provided with four separate and very well written programs and I do wish more companies could adopt a similar price structure. So what are the programs involved?
The first is called Balance and involves calculating the movement of a weight and its balancing movement. Unfortunately, the examples are very simple but the graphics are very good.
There follows two Meter programs, one in colour and one in high resolution, for you to choose from.
Whilst the programs work well enough and the magnify facility is excellent, I can't really see the point in using a £400 computer for such a simple task. Also, there is no demand to use the correct units which is a pity.
Therm is a similar program involving the reading of thermometers of three types and has a magnify facility too. This is of more use I feel.
Finally, Light involves the prediction of refraction or reflection paths and is graphically excellent. All told the package could help those preparing for O-Level or CSE.
