EdGEO, initiated in the early 1970s, supports local workshops on earth science for Canadian teachers. It is coordinated by the Canadian Geoscience Education Network of the Canadian Federation of Earth Sciences .
While the resources are available in English only, the plan is to translate them into French in the near future. The activities seem geared to secondary, but can be easily adapted to Elementary students.
Bringing Earth Science to Life (one of the downloadable ressources) contains classroom-ready activities that have been used successfully and fine-tuned in EdGEO workshops all over Canada.
