After 20 years of teaching at Brookfield Central, I am saying goodbye. Although I spent the majority of that time in the physics classroom alongside my learners. That changed for my last 18 weeks. I ended up in a place similar to where I started, teaching chemistry and biology. So, rather than dealing with juniors and seniors at the end of their high school careers, I was in classrooms with freshmen and sophomores still trying to find their place. At the same time, I was learning and teaching a set curriculum I hadn't taught in over a decade. So, we were learning. But, of course, I already knew the content. The point of this post is to take a step back, take in, and share the gratitude from the last students I had in my 20 years at Brookfield Central High School through the cards and notes they made for me on my last day with them. I don't take many yay me moments. But after 20 years, I think I'll soak this one in.
I have been slowly trying to implement the Next Generation Science Standards (NGSS) into my classroom. Our new Wisconsin State Science Standards were designed with the NGSS in mind. They align very well. So please forgive me if my language focuses on the NGSS in this post. In a previous post I discussed tools for dealing with models in science class. This post will focus on Planning and Carrying Out Investigations. As the name indicates, there are two major components to this practice 1) planning investigations 2) conducting investigations. Before looking closer at each aspect, we need to look at the purpose of investigations in science and engineering. To quote the practice according to Appendix F of the Next Generation Science Standards: Scientific investigations may be undertaken to describe a phenomenon, or to test a theory or model for how the world works. The purpose of engineering investigations might be to find out how to fix or improve the functioning of a technological sy...
