Deanna Cullen shares highlights from the April 2018 issue of the Journal of Chemical Education.
Matt Vonk and Peter Bohacek have just created a handful of new chemistry activities that are based on interactive high-resolution video. These classroom-ready experiments have interactive tools so that students can perform the analysis and record data themselves. In some cases, students can even change variables.
This past March, I ran a multi-day poll on Twitter that was designed to be a fun way to determine the “best” element on the periodic table. I’m sharing about the poll here on ChemEdX in case others might want to try something similar in their classrooms.
he Biennial Conference on Chemical Education (BCCE) will be held at Notre Dame in South Bend, Indiana from July 29 through August 2, 2018. This is an excellent professional development opportunity for high school and college chemistry instructors.
As a secondary science teacher, I have contact with my students everyday. Making relationships and learning about all of my students is key to letting them know that I am invested in their success.
The solution to Chemical Mystery #11, which involves the Leidenfrost Effect, is presented.
