This week the students were introduced to Light and Optics. Monday the students completed an activity in which the students researched the Electromagnetic Spectrum. Tuesday, with guided notes we went over some examples of problems that included time and distance calcuations with the speed of light in addition to going over the visible spectrum and a review of the Electromagnetic Spectrum from the previous day. On Wednesday the students participated in four different stations in which they explored the nature of light. The students explored images of flames projected onto a screen, and also discovered why laser beams themselves aren't visible. Finally they developed the Law of Reflection, and also explored polarized light.
Thursday the we developed the students understanding of the Law of Reflection, and introduced Snell's Law and Refraction. On Friday we tried a new technology in the classroom. It was an online quiz. We had a couple hiccups (computer's not logging in quickly) but overall, the quizzing technology is one that I will implement again. This tool helps me quickly assess where the students are at in their understanding, and what we may need to brush up on.
