NASA Explorer Schools and the National Science Teachers Association are hosting a 90-minute Web seminar for educators on Jan. 10, 2013, at 6:30 p.m. EST. This web seminar features two lessons: one on extremophiles and the other on searching for life. Review criteria for determining if something is alive and learn how students apply the criteria in a hands-on activity. A video will be shown that connects the activity to a NASA mission. Collaborate with other participants about ways of using and adapting the activity. Extension activities for students interested in the topic will be provided.

This seminar is offered again on April 18, 2013.
