Science!* New Photoessay: Lynn Holmes http://www.keystone.fi.edu/visits/lynnholmes.shtml Step inside Lynn Holmes's classroom as she and her first grade students at Edgewood Elementary School in the Pennsbury School District explore the states of matter with FOSS's Solids and Liquids module. Her students made wonderful observations and prompted all kinds of new thoughts and discussions. Take a look and see what they learned. Web Pick of the Week ISS EarthKAM Lets Students Take Pictures of Earth http://www.earthkam.ucsd.edu/ ISS EarthKAM is a NASA-sponsored program that allows students to photograph a wide range of features of Earth, using a remotely operated digital camera mounted in a window on the International Space Station. Since 1996, ISS EarthKAM students have taken thousands of photographs of Earth by using the world wide web to direct a digital camera on select space flights and currently on the International Space Station. The website contains thorough and well-thought-out sections for educators and students as well as an image library. Awesome Science! Scientists Confirm Massive Black Hole in Milky Way http://www.reuters.com/news_article.jhtml?type=sciencenews&S toryID=1586318 Scientists from the Max-Planck Institute for Extraterrestrial Physics said they have discovered a huge black hole at the center of our galaxy, a mysterious celestial object that sucks in everything around it including light. By observing the orbit of a star around the invisible gravitational field, an international team of scientists has eliminated other possibilities of explaining the phenomenon. "It is a great step forward," said Dr. Reinhard Genzel, who led the team. He continues, "We have been able to exclude some still possible alternative configurations... there is nothing left that one would consider realistic and possible, other than a black hole." Black holes are thought to be the remains of dead quasars—the powerful, super-bright hearts of galaxies. Read more about this discovery through the link above. |
