Thankyou for visiting this page. 

I produced these booklets for the Science Faculty at Astrea Academy Dearne. As such, they are protected by intellectual property rights. 
 
If you choose to use them, or parts of them, please give credit where it is due. 

Also, I need to acknowledge the generosity of all those that have shared their booklets. These helped immensely in shaping ours.
 
Any feedback would be appreciated. 

Best wishes,

Derrick (Jamie) Venning
