If you missed the virtual conference from DiscoveryEducation SciCon then you can see the archives of the day's activities here! There are videos, presentations and downloadable pdf files of documents you can use in your classroom. Other links on the page lead to DiscoveryEducation Science Class, Integration Station, and Learning Lab. You don't even have to log in to Discovery to get to this page of resources., or this page of Thinking Green. There is also a link to homework helpers for science at this link.
It is worth looking around the site to find some little nugget you can use in your curriclulum! Enjoy :)
