Snakes and Ladders game for Year 7 to introduce ideas of factors that affect population numbers. Just download and laminate a snakes and ladders board e.g. from http://www.printableboardgames.net/preview/Snakes_and_Ladders, then students play the game as normal. The only difference is that when they land on a snake or ladder they take a 'snake' or 'ladder' card and read out the cause of their good or bad fortune ie. a reason why their population has increased or decreased. To be honest, I've rushed it a bit so I'm sure someone could adapt it. It could also be adapted for older years; they could come up with their own reasons for population changes.

Includes line drawings that can be used for colouring in the structure of the eye, including an outline font so this can be coloured in the same colour as each eye structure. 2 different versions of labelling activities are included plus a sheets for labelling and then describing the function of each part (with answers). There are also activities with diagrams to help understand accommodation on near and far objects, correction lenses and links to useful Scientific Eye video clips. I have included a pdf in case the fonts do not open correctly in powerpoint. But do let me know if you have difficulties. There is also some information about the requirements for each exam board. *Freeware font from Jess Latham, Blue Vinyl Fonts
