Discovering Antarctica is an interactive website and resource developed by the British Antarctic Survey and the Royal Geographical Society. It has a host of features suitable for an introductory level to Antarctica (~11-14 years; UK key stage 3).
There is a number of resources, including ecosystems and food webs, science and exploration, tourism, challenges, and of course, introducing Antarctica. There are interactive activities designed for individual, group or pair work, many of which are in interactive multimedia format.
The website is not a scheme of work, but is a resource for teachers to dip into depending on their curriculum needs and priorities.
