Mentoring Science Teachers

Perhaps one of the most important roles that science teachers play, apart from helping their students become excited about and learn science, is being a mentor to an apprentice or beginning teacher.   My own experience in the mentoring process was as a beginning teacher at Weston High School where I was mentored by Irv Marsden, physics teacher and department head.  Although there was not a formal mentoring process at Weston High, Irv took me under his wing, and created an environment of support and encouragement, and shared his knowledge of science teaching in a way that was open and humanistic.  … Read more

Why the film, “Waiting for Superman” demonizes public education

Over the past month, I’ve written several posts about the film Waiting for Superman, and wanted to return to it today, and point you to the Bridging Differences Weblog by Diane Ravitch and Deborah Meier, and their criticism not only of this film, but how the forces behind the film, and the standards and test culture have resorted to the demonization of public schools, and misleading the public about the “success” of charter schools.

Water on the Moon

NASA has reported that if astronauts heated lunar soil, it would yield water that could be purified and used for drinking, or separated into Oxygen and Hydrogen and used for rocket fuel.

Science at the White House: An Oxymoron?

Science at the White House.  This is not a contradiction in terms.  This is not an oxymoron.  For the first time, the President of the United States brought to the White House award winning science projects, much like bringing the championship football or baseball team to take pictures with the President.  Yet, this event was much different.  The winning science fair projects were set up in the State Dining room, and the President, as well all of the invited guests spent more than hour perusing the science projects, and in the case of the President, talking with the students about their projects.… Read more

Geology of Chile

Chile is a very long but narrow country located in one of the most active tectonic regions of the earth. As seen in the map below, Chile is close to or part of four tectonic plates: the Antarctic Plate, the Nazca Plate, the Scotia Plate and the South American Plate. The eastern edge of the Nazca Plate is a convergent boundary in which crustal rock is moving under the South American Plate and the Andes Mountains, forming the Peru-Chile Trench.… Read more
