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.

Simple Activities to Integrate Particle-Level Diagrams

There have been many conversations within the Chemistry Education community surrounding the revisions to the AP curriculum. Twitter has been buzzing with instructors debating how to implement the changes, conferences and workshops have participants deconstructing the data from last year’s exam, and classroom teachers are working diligently to prepare their students for this year’s test. One way the College Board has tried to shift the AP curriculum away from algorithmic problem solving and toward more meaningful conceptual understanding is through the use of particle diagrams.

The start of a new school year is fast approaching and as we begin to plan for our first days back with students I thought I’d share one of my favorite first day activities.

Cross-Discipline Discussions on Energy

Have you ever thought about the ways we, as chemistry teachers, talk about the concept of energy?  Think about all the different terms we use when we talk about the role of energy in our curriculum:  endothermic, exothermic, heat, specific heat, heat capacity, enthalpy, tempera

Connecting and Collaborating with ACS

As this is my first blog post, I’d like to introduce myself to the ChemEdX community. I currently teach Chemistry I, Introduction to Organic and Biochemistry, and AP Chemistry at The University High School of Indiana. I use the Chemistry Modeling Curriculum in my classroom
