Elements, Compounds, and a Vocabulary Card Sort

How many of you could recite, word for word, a definition you learned in school? When you first memorized the definition, you could state “inertia is a property of matter”, or “density is mass over volume.” However, you struggled to apply it to a new situation and maybe you were unsure of how to construct a model of what it meant.

Chemistry ROCKS!

With a Master's degree in geology, I have a deep and abiding love for rocks and minerals. The great thing about geology is, it's all about chemistry! I want to share one of my favorite links between geology and chemistry that my students think is pretty cool too. 

Introduction to Modeling Instruction: a distance learning course offered by AMTA

AMTA’s Introduction to Modeling Instruction distance learning course will focus on the role of models and modeling in learning as it relates to teaching STEM content in both formal and informal contexts. Participants will review fundamental theories of thinking and learning and examine the latest theoretical trends.

Two Simple and Cheap Illustrations of Phase Equilibrium and Vapor Pressure

A favorite demonstration is to boil water by lowering the pressure in a bell jar using a vacuum pump. Unfortunately, purchasing a bell jar, vacuum plate, and vacuum pump can run upwards of $1,000 which poses a hardship for many teachers. Here are two simple and inexpensive demonstrations of phase equilibrium and vapor pressure.

Drawing Particulate Models

Embracing the idea that students already create an image, create an idea, of what is happening when they observe a demonstration, lab or activity. The goal is to have the students make that model more concrete through drawing it.

Confessions of a Part-Time Modeler

In the summer of 2016, there was a Modeling WorkshopTM for High School Chemistry just before BCCE in Colorado. I already had planned to go to BCCE, so I took the plunge. Two weeks of daily instruction and labs in student mode as well as teacher mode debriefing was exhausting and exhilarating at the same time. I left with a folder and flashdrive of curriculum resources provided by AMTA (the American Modeling Teachers Association.
