While toddling about the Australian Museum site being gobsmacked by science photography, I thought I'd locate a couple more useful links to pop on the blog.
The Education Services site has a bunch of possibilities to explore, including videoconferencing, teacher previews/talks, competitions and more. http://australianmuseum.net.au/education-services
The Collections section is the gateway to exploring an extensive number of options, including biodiversity, natural science collections, interactive science activities, cultural collections and more. http://australianmuseum.net.au/research-and-collections
Minerals and fossils http://australianmuseum.net.au/minerals-and-fossils
Cultures (including Australian Aboriginal and Ancient Egyptian material) http://australianmuseum.net.au/cultures
Worth sharing with your Science staff, Society and Culture teachers, Aboriginal committee/liaison group/Aboriginal studies teachers, History teachers and others. You don't have to be in Sydney or NSW to make use of many of the resources on the site.
