August 11, 2009 Using the Data of the EarthScope in Education Susan Eriksson, UNAVCO Director of Education and Outreach

Approach for today PurposePurpose What types of data for EarthScope componentsWhat types of data for EarthScope components What will you use it for?What will you use it for? Resources for dataResources for data Resources for educational frameworkResources for educational framework Plan for after the workshopPlan for after the workshop

Why EarthScope?  Scientific discoveries - the ‘content’  things we know  things we don’t know  How we go about ‘finding out’  Skills of science -?  Exploration - inquiry
