Simple Things

Teaching has become a bit of a conundrum lately. Increasingly we are using more and more technology to engage the students and make learning more interesting. I support this effort fully and have agreed to be a CFF (Classrooms for the Future) teacher in my school. This means lots of training and the access to some great technology for the students. Having said that, I always marvel at the power of “low tech” demonstations and activities where there is no electronic/computer/internet component. In order to illustrate the umbra and penumbra of the Moon during a solar eclipse, it was marvelous to see students “get it” when a light source, styrofoam ball, and a globe were positioned in just the right way. Understanding the synchronous orbit of the Moon requires a student to circle the room, while always facing the earth in the center. Currently, my students are determining the percentage of oxygen in the air by observing the reaction of iron and oxygen (rusting) in a simple set up (see photo). Ah, the simple things!
