You probably know what happens when you place dry ice in water. Do you know what happens when dry ice is placed in acetone or glycerin? Read this and find out!
The American Modeling Teachers Association (AMTA) is an international, professional community comprised of over 2800 passionate, innovative, and connected educators. Members include high school and university level STEM educators, educational research professionals, as well as pre-service and retired teachers.
In this "Pick" I'll briefly describe how I use the ChemDraw iPad App for creating structures for my teaching. I also provide a link to a tutorial where I share some tips on how to get started using ChemDraw on your iPad.
Last month, I shared about a new PD opportunity I had the privilege of participating in called Gizmos. You can read about it here. After Thanksgiving break, my Chemistry 1 and Honors Chemistry 1 classes began our Chemical Reactions unit.
I have used several different versions of the Silver Mirror or Tollen's Test lab. I am sharing the method that has proven to be the most reliable for me. The solutions should be made fresh, the directions must be followed closely and timing is very important. I like the fact that relatively small amounts of the chemicals are required, but as always you must be vigilant with safety precautions.
15 minutes of prep time and 20 minutes of class time if you have multiple hoods available for students to use. I only have one hood, so I have another activity for students to complete while two groups rotate through the lab over two 60 minute class periods.
Improving Student Understanding
The December 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: synthesis in the laboratory, examining and using a flipped classroom, improving labs through multimedia-based and student-directed learning, using applied math for better understanding, improving student understanding of thermodynamics, inclusive chemistry teaching, using manuscript review for assessment, climate chemistry, spectroscopy experiments, performing safe demonstrations.
Sharing the topics of measurement and the metric system could at first thought be seen as largely a visual endeavor. Students might measure the lengths of various objects and then convert their results from one metric prefix to another. Ditto mass or volume, with their respective measuring tools. What if the sense of touch could be incorporated to provide a different aspect of learning, beyond simply manipulating the objects?
High school chemistry teachers in U.S. and U.S. territories can apply for a Hach Professional Development grant to fund up to $1500 of expenses. Applications will be accepted through January 4th. Qualified expenses include registration, travel, tuition, books/resources and substitute teacher pay. Activities must be completed by August 31, 2017. Decision/notification date is February 28, 2017.
