Congratulations to Grazyna Zreda who solved the Chemical Mystery of the Mentos candies! To conduct this trick, two white Mentos candies are placed in separate beakers that both contain universal indicator. One of the Mentos candies turns the indicator slightly green, indicating the presence of base.
Here in Michigan we are entering into our 4th week of school. My Honors Chemistry 1 students will be having their first test this week and my Chemistry 2 students will be having their stoichiometry test in 2 weeks. Things are moving along and I am daily observing improvement in my students.
I'm looking for a reliable procedure for an undergraduate organic lab experiment: oxidation of diphenylmethanol to benzophenone. I am updating our lab experiments and was thinking about introducing phase transfer catalysis, linked to a 2-step Grignard synthesis ( bromobenzene --> phenylmagnesium bromide --> diphenylmethanol --> benzophenone). I have found a JChem Ed paper that sug
Shelly Belleau is a chemistry and physics teacher from the Denver metro area. This school year she is working as a teacher on special assignment at the University of Coloroado, Boulder. Shelly anaitcipates returning to the high school classroom next fall. Below is our coversation about inquiry.
1. How do you define inquiry? or What does inquiry look like to you?
National Chemistry Week this October 19–25 offers a chance to take a trip to the candy shop with the theme "The Sweet Side of Chemistry—Candy." Looking for some tasty chemistry resources? Two upcoming webinars will help you stock up.
Another chemistry demonstration accident has happened. This one was at a museum in Nevada. In preliminary reports, it looks as if several children were injured. One child was held overnight in the hospital. See the article posted on Yahoo News. (Thanks to Tom Kuntzleman for the link.)
On September 2, the American Association of Chemistry Teachers (AACT) launched its official website, loaded with lots of resources and member benefits. If you visit teachchemistry.org, you will find many great tools that K–12 teachers of chemistry can use in their classrooms; the new online periodical, Chemistry Solutions; professional development opportunities; and a community for you, in addition to many other benefits.
