Correcting Science

What we call misconceptions

Science is cool. It allows us to step back and reason why things are the way they are.  Most importantly it fuels us to keep questioning why. Asking why is an important aspect of learning, and is a huge part of the way classrooms run, on average a teacher will ask 300-400 questions just in a day (Vogler 2008)! However, what happens when a student does not have the correct answer to a question? Are they deemed wrong? Is it a misconception that we must fix?

Extension Activity with Isotopes Matter

Isotopes Matter Interactive Periodic Table

After receiving positive feedback from Peter Mahaffy, the IUPAC project co-chair of Isotopes Matter, I decided to add an additional component to the original isotope assignment I posted. The second component of the assignment focuses on the applications of both radioactive and stable isotopes using the interactive IUPAC periodic table.

Time required: 

55-60 minutes for both parts of the extension activity

The Importance of Safety.

testing the safety shower

 Undergraduates Need a Safety Education is the title found in the commentary section of the September 2016 Journal of Chemical Education. It is written by Robert H. Hill Jr and it explains the lack of safety education in chemistry curriculum.  As I read this, I thought back to my safety education that prepared me for my role as a high school chemistry teacher and felt I was very fortunate to have had an undergradutae class that was specifically designed to teach chemical safety. 

Google Forms as an Assessment Tool

This school year my district is launching a 1:1 Chromebook initiative. 6th and 9th graders will receive their Chromebooks next semester as part of the rollout. In the meantime, I continue to have access to my Chromebook cart from the Blending Learning pilot I participated in last school year. My goal is to incorporate even more tech use when appropriate; so far, I have increased Chromebook use in my classroom for things like warm up questions, EdPuzzles, and quizzes. My experience with quizzes has been especially interesting.

Using IUPAC's Isotopes Matter as a Digital Learning Tool

Isotopes Matter

Isotopes Matter is a digital learning tool, developed by IUPAC Isotopic Periodic Table, designed to explain isotopes as well as their importance. This resource incorporates mass spectroscopy data into each of the key ideas as well as provides multiple examples as to how varying isotopes are commonly used.

Time required: 

Using Isotopes Matter and the class discussion: 55-60 minutes
