What an exciting week it has been in the Discovery Lab. The students (and teachers) learned many interesting facts from our career speakers. Click on the photo collages below to enlarge the images. Dr. Guido Cervone talked to Barrett students about being a researcher and university professor. The students and teachers learned a lot about remote sensing using birds, kites, balloons, airplanes, and satellites. We learned about geostationary and polar orbiting satellites. Dr. Cervone showed us how he uses satellite images to study hurricanes. You can visit the J-Track 3D from NASA to see different satellite orbits. http://science.nasa.gov/Realtime/jtrack/3d/JTrack3D.html Thank you Dr. Cervone for visiting Barrett! Maybe in the future we can come visit you and tour your labs George Mason University.
Mr. Hill talked about his many different roles at XM Satellite Radio. He is sometimes called a jack-of-all-trades. He showed us how the satellites are launched. We were surprised the rocket launches with the satellite from a ship! We watched videos of successful launches and not so successful launches. We learned the satellite is powered by solar panels and batteries. We watched a video clip of an antenna unfolding. The music playing during the video was Who Let the Dogs Out, so of course we all sang along with the chorus. It was fun to listen to music from XM radio. Mr. Hill brought in models which made his presentation even more interesting. Thank you Mr. Hill!
Mrs. Green is a wildlife biologist with the United States Fish and Wildlife. She showed how biologists attach radio transmitters to animals to learn more about them. This information helps the biologists protect the endangered species. She explained that what she learned in school is very important to her job. She must read scientific articles and write reports. She also has to keep notes when she is out in the field. Mrs. Green talked about invasive species that can take over an ecosystem. She also showed us items that had been made from endangered species that had been taken away from people. Mrs. Green brought bookmarks, stickers, and temporary tatoos for the students. Thanks Mrs. Green!
