What you are about to see is a small selection of sample lesson slides from a selection of the eight lessons on the ‘Meteorology ... Simply for Yachties’

CD.On this demonstration disc, the slides under each lesson

title do not necessarily follow any specific order and there are many other linking slide animations that are not show that normally provide the lesson with the ‘flow’ that is not immediately apparent in this demonstration. Naturally, the

full version has all the links and ‘flow’ necessary to understand and absorb the topic in question.

The full version of the ‘Meteorology .... Simply for Yachties’ CD is made up of well over 370 animated lesson slides covering all

8 lesson topics. Let’s now have a look at some of the lesson slides .......

At each stage during viewing, allow the animation to run for a couple of seconds before using the mouse button or scroll wheel to move on. On the full version CD, each lesson has a self testing

interactive quiz at the end of the lesson. An example is also given on this disc.
