Solution to Chemical Mystery #6 is presented. Also, concepts related to the chemical can crush demo are briefly discussed.
Can you figure out how this experiment works?
I met Jenelle Ball in Denver, CO at the Spring 2015 National ACS meeting. She is soft spoken and easy to get to know quickly. Jenelle’s biographical information is impressive. She earned a BS and MS in chemistry. While in graduate school, she recognized a passion for the process of teaching and learning which led her to teach high school chemistry. Most of her career has been spent at Chico Senior High School in Chico, CA. She was also fortunate to have the opportunity to take a rare sabbatical from high school teaching and earn a MA degree in teaching and learning.
This past week, as part of our Thermochemistry unit, my students were completing one of my favorite Target Inquiry Labs entitled “ A Very Cool Investigation”. We were using calorimeters, dissolving ammonium nitrate, and my students were recording the change in temperature using a digital thermometer. Some of my students had noticed that with si
As with most conferences, even the small ones, there is way more than I could put in one blog. Here is what impressed me the most. Several people from the national and local ACS made a point of doing whatever they could to reach out to teachers. As Dr. George Bodner said (and I am paraphrasing), the ACS first looked at what they could do to teachers. They then examined what they could to for teachers. Now they are asking, "How can we work WITH teachers.
Chemistry education faculty at Stony Brook and Carnegie Mellon University want to help AP chemistry teachers adapt to the new AP curriculum, and will create a new website to help support teacher needs: the APChemCollaborative (APCC). Could you please take a moment and help us understand you and your needs better, so we can create a successful design?
I recently stumbled across a blog about the use of BCA (Before Change After) tables for stoichiometry written by Lowell Thomson. I was thrilled to discover ChemEd Xchange! I wanted to share my journey, spurred on by my students, into the extensive use of the BCA approach in AP and IB chemistry. I hav
For my students and me, the AP Chemistry exam does not mark the end of the school year. Once the AP exam is over, my students are exhausted but our class continues to meet for three more weeks. Each year we complete a qualitative analysis lab, but this year we finished earlier than I anticipated. For the first time all year, I have the luxury of time.
