Still I Rise: A Student Perspective

Black History Month

In this blog post, I’ve asked Natalie about her journey as a woman of color along the path toward a future in a STEM field. I can’t begin to understand her perspective, so I’ve asked her to lend her voice to this issue. I believe it is important that we, as educators, take some time to reflect on what she has to say. Sometimes, the things we don’t say are resonating just as loudly as the things we do.

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.

Boiling Water, Heating Curves, and Can Crushes

In an effort to better understand my high school students' knowledge of what is happening during phase changes, heating curve calculations, and the ever popular can crush demo, I run them through a series of activities. First, I ask my students "What Temperature Does Water Boil At? 

Time required: 

1.5 days to do all the activities including lecture on heating curve calculations.

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.
