A student of mine, Anthony Shepherd, and I worked together to develop a new chemical riddle. Check out the video and see if you can come up with an answer.
I am honored for the invitation to write for ChemEd X and am looking forward to being part of this collaborative chemistry teaching community! I’m Shelly Belleau, a Chemistry and Physics teacher in Colorado.
In the video below, you can find the solution to the chemical riddle involving the food dye and bleach experiment. You can also find a description of how to set up and carry out the experiment. Finally, an extension to the activity is prese
Can you solve the chemical riddle described in the video below?
I attended 5th grade camp with my son, Stevie, this week. Camp Miniwanca is a beautiful property between the vastness of Lake Michigan and a much smaller inland Stony Lake. The program is based upon the "experiential learning cycle". Small groups of campers work through a series of challenges. The counselors and chaperones allow the children to struggle, disagree and fail. Of course, success is congratulated and enjoyed. Children choose their own goals for individual challenges, so they have an opportunity to strive for their "best self" and meeting or exceeding whatever goal they have made is celebrated. Children were given many team and individual responsibilities. Every part of the day at camp had a purpose. Stevie is the youngest of my children. I have chaperoned several camps before and I attended a few as a child myself and one as an adult participant. This one was by far the best run camp I have attended. Many camps give lip service to experiential learning, but the thing that I observed at Camp Miniwanca that impressed me was there attentiveness to the entire process of the experiential learning cycle.
Here’s a great project to try with your students: build a periodic table out of Lego blocks. We did this a few years ago at Spring Arbor University, working with teachers and students from Hardin Valley Academy in Tennessee. After we built our Lego Periodic Table, we used Velcro strips to hang it on a wall on the chemistry floor of the science building on campus.
Earth Day is just around the corner. If you are looking for some ideas to highlight environmental issues, the Journal of Chemical Education is offering free access to many articles and activities that you will find interesting.
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
