Upon sharing my array of apps with some future chemistry teachers, they asked why so many Periodic Tables? My response was “Well not all periodic tables are the same”, upon which was followed by several blank stares...Let me explain: I currently have the following periodic table apps loaded on my iPad...
In this blog post will describe a process I now use for providing specific lab report feedback using an online Comment Bank.
How can I engage my students (and myself) for the last half of the semester? I read recently that the human attention span in 2015 is 8.25 seconds(link is external), which is down from 2000’s 12-second span. Currently, we are just beneath goldfish, who can attend to one thought for 9 seconds. I’m not sure of the methods of the research study, and I maintain a level of healthy skepticism. However, I admit my thoughts often spring from topic to topic like a bubble gum machine bouncy ball.
Students who are tired of "pen and paper" work now get to get up and use their answers to mass something or find the volume of something and see if they are correct.
In my high school chemistry class, a unit we cover is that of atomic structure. In particular, given an elements symbol, mass number, atomic number, and charge, the objective would be for the student to determine the atoms number of protons, neutrons, and electrons. I have several apps/program suggestions that can be useful for this purpose.
I’m a first year AP chemistry teacher. My emotions swing from fear of inadequacy to confusion in pacing to acute awareness of the number of years since college chemistry to desperation in grading 55 lab notebooks to exhaustion with inexperience. Honest truth: I'm studying. I'm studying a lot.
Technology is a word that can generate a great deal of debate in a chemistry classroom. I got into an interesting conversation with a teacher who is new to my school this year as she was moving into her classroom next to mine.
Over the last few weeks, I have been working with a middle school physical science teacher, Morgan, to develop a PBL experience for her students as they learn the basics of the atom, periodic trends, and bonding types. She is a first year teacher and has been so fun to work with. It has been really eye opening to work with her - in a good way. As I work with another teacher, I have realized that I have forgotten how big of a task it is to create ALL OF THE PIECES of these experiences for students (and let’s be real, we are a bit crazy to create this during the school year). My goal is always to be real with my writing and experiences, and here is something a bit more real for you all. In this post, I am sharing what it is like to develop a project from both my perspective and, most importantly, from Morgan’s. Think of it as a view from the trenches.
We had just had some snow days and I had the feeling that I was getting behind. In one class we were approaching the topic of orbital diagrams and electron configurations. I was tempted to just say, "Here are the notes." Sometimes there is nothing wrong with that. This time, something was eating at me. Instead I picked a POGIL (link is external) from the "High School Chemistry" (link is external) book that presented the ideas through guided inquiry.
The new IB curriculum includes compound identification using NMR, IR and Mass spectroscopy. My current high school lab does not have any of these available. And that's no surprise, given the cost of these machines is far out of our budget. And while some of you may be lucky enough to have a connection to a local university or college, for the rest of us what are the options when it comes to teaching spectroscopy?
