It is becoming increasingly important for citizens to understand various concepts related to climate change and global warming. This post describes several chemical concepts that are pertinent to these issues, in the hopes that teachers of science and chemistry can introduce the topic of climate change into their classrooms and everyday discussions.
To grasp the concept of oxidation and reduction reactions, I have my high school students write half reactions to show the loss and gain of electrons by the substances being oxidized and reduced. To help with this concept, I developed a quick lab activity involving the reaction between magnesium metal and dilute hydrochloric acid, which in turn led to the students collecting the hydrogen gas and then testing for its presence.
It’s the end of one semester and the beginning of another. Final exam week. For the first time in my teaching career, I had my grades caught up and posted prior to the beginning of final exams. This gave me time to reflect and plan ahead.
Whether you are introducing collision theory or something more demanding like reaction order, the reaction between sodium thiosulfate—Na2S2O3 and hydrochloric acid can provide a consistent, accurate, and engaging opportunity for investigating these topics.
This webinar will introduce the Claim, Evidence, Reasoning (CER) Framework, implementation strategies, and how it helps create a classroom culture that more accurately reflects the ways progress in scientific knowledge and communication take place in the real world.

The NGSS calls for the use of the engineering design process in science classrooms K12. Let’s discuss what this means for the modeling classroom. Bring your ideas about how and when to integrate the engineering design process and engineering projects into your classroom.
This session will be hosted by Kathy Malone and Anita Schuchardt.
This webinar will discuss how to approach teaching stoichiometry problems using a table set-up (commonly referred to as Before, Change, After tables) to make the process visually appealing and more intuitive for students. The process emphasizes proportional reasoning and explicitly connects the calculations to the particulate nature of matter.
Connections to equilibrium calculations will also be discussed to show how this method can easily be integrated in to your curriculum and benefit your students in more than one area.
A unique professional development opportunity for STEM teachers from Indiana and Alabama.
