BEAKER - Mix Chemicals

This week, one of my students alerted me to some mobile apps featuring chemistry. One, in particular, seems to be mostly free and incorporates a hands-on approach to conducting virtual laboratory experiments. The app is called BEAKER - Mix Chemicals and is offered by THIX on the Apple and Google Play Stores. My student demonstrated how the app works and I gotta say - it's pretty sleek.

LED lights and the Periodic Table

Every LED light has a "band gap". Electrons are pushed into an empty orbital which is negative and then the positive end of the circuit attracts the electrons. As they go down in energy through the band gap, they emit light. The larger the band gap, the more energy, the smaller the wavelength and the closer to the "blue" end of the spectrum. So, the key is to try to control the band gap and thus control the color of light. 

My First Experience Using Claim-Evidence-Reasoning (CER) in the IB Chemistry Classroom

Whiteboard for C.E.R. Discussion

In a recent blog post, Ben Meacham shared his use of the Claim-Evidence-Reasoning Framework. I have started using this approach for class discussion as well, and will share some ideas and thoughts about the process.

Chem101

Chem 101 is a FREE (for a limited time) app for any apple or android device designed to improve engagement in college chemistry courses. Although the intended audience is college level, there are modules appropriate for high school as well. Students can use the app to practice on their own, or instructors can create in-class or at home assignments.

Implementing the Claim, Evidence, Reasoning Framework in the Chemistry Classroom

Claims, Evidence & Reasoning example

For me, the first step toward teaching my students how to critically think about how they structured an argument or explanation was to implement the Claim, Evidence, Reasoning (CER) framework. While the premise behind CER isn’t anything new to the way science teachers already think, it provides an entirely different approach toward how students connect their experiences and previously learned content into something that is much more reflective of being scientifically literate.
