STUDENT QUESTIONS NEEDED: EARTH DAY VIDEO CHAT

To celebrate Earth Day 2011, the Education Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif., is hosting a live Web video chat where your students can ask a NASA/JPL scientist questions emailed in advance. Questions should be on the topic of Earth science. Our chat is best suited for students and afterschool groups in grades 4-6. 

Our guest will be NASA/JPL research scientist Annemarie Eldering, who specializes in clouds, aerosols and trace gases in Earth's atmosphere. She is currently the deputy project scientist for the Orbiting Carbon Observatory-2, a NASA satellite mission now in development that will measure atmospheric carbon dioxide, the leading human-produced greenhouse gas driving changes in Earth's climate.
