A share-a-thon is a place where teachers can voluntarily upload their files for other teachers to use. When a teacher submits a file, it is catalogued and placed into a database. The share-a-thon is new to this subject. Check out the established Earth Science webshare and see the possibilities of this share-a-thon. Please consider sharing pieces of work that you feel is your best by clicking here. Thanks! Christopher Sheehan
