Here is a link to a set of clips that deal with many of the issues that are dealt with or mentioned in the pre-release materials. Here is another link that will take you to a range of different websites that will help you in your research.
Here is a link to a site that animates a lot of the available data for you.
If you lose your copy of the pre-release then there is a copy here. There is also a copy of my version of the booklet I produced to help you.
I have used the web to collect these resources for you and would like to acknowledge the work of the teachers that contributed the original resources that I have either used or adapted.
