I was quite excited to learn about the “So You Think You Can Demo” competition at the upcoming ChemEd 2015 conference. I enjoy learning about new chemistry dem
Science is creative; it requires new ideas, new patterns, and new solutions to old problems. A deep understanding of the periodic table is the most critical knowledge in chemistry. I want my students to experience the table and conceptualize its trends in a deeper way.
Some orange peels can cause balloons to pop. The compound in orange peels called limonene is responsible for this effect. Limonene is responsible for the wonderful smell of oranges, and it is a liquid at room temperature.
Today in my IB Chemistry class we were reviewing the Born-Haber cycle. This has proven particularly challenging in the past so I wanted to try something a bit different and have the students review in groups. The task for each group of students was to create a visual Born-Haber cycle for potassium oxide - ignoring the math and calculations but instead focusing on each process within the cycle. I'd like to share how I grouped students using periodic properties.
With spring just around the corner and warmer weather approaching, I find that I’m in active summer preparation mode. This is the time of year when I’m trying to plan for the perfect summer balance between professional development and relaxation – both professional growth experiences in my
Labs! They have been the most overwhelming part of my career in chemistry. I felt the least prepared in this area when I began teaching and walked into my first lab as a teacher. Knowing all of the chemicals and equipment were under my care was a bit terrifying.
In this age of scientific inquiry, molecular modeling, digital classrooms, and differentiation, I felt downright guilty about any teacher-centered time. My classroom is flipped after all. I’m not supposed to be lecturing, right?
A fun experiment to conduct when discussing phase diagrams is the melting of solid carbon dioxide (dry ice).
