December is a busy time for many educators as we try to wrap up content before a long break and maybe incorporate fun activities into the curriculum. There are concerts, field trips, projects, presentations, and even variety shows to “celebrate the season.” However, I find that when schools try to get into the “holiday spirit”, they may unintentionally create an environment where students and teachers may feel excluded.

One aspect of Argument Driven Inquiry that has not been discussed here is the peer editing piece. I have succesfully tried it out with my own students.

In an effort to implement the science and engineering practices of the NGSS, I have tried to introduce argumentation as a practice into my chemistry courses. I share some growing pains and what I have learned through the process in this blog post.

The solution to Chemical Mystery #13: Bye Bye Blue! is presented. This experiment is useful to demonstrate to students when discussing acid-base indicators, neutralization reactions, or the acidity of carbon dioxide when it dissolves in water.

Several teachers I know have had circumstances present themselves in which they may not always be able to provide lab experiences in a traditional lab setting. They still want to provide students with rigorous problem solving situations that require students to use the scientific method. Could rigorous take home labs possibly be the answer?

You are likely aware that diamonds are converted - albeit slowly - to graphite under normal conditions. Thus, diamonds don't last forever, in contrast to the popular advertising slogan. However, did you know that you can use chemistry to prove that diamonds are not forever? It's simpler than you think...

This five puzzle mystery aligns with my chemistry curriculum after instruction on the properties of elements and electron configurations. I use this mystery as a review to prepare for assessments over the properties of elements, symbols on the periodic table and the difference between groups and periods. Also incorporated within the puzzles are basic trends such as the number of subatomic particles, mass number, melting point, and other characteristics of specific elements.
