My IB seniors are just wrapping up our unit on electrochemistry and redox. This has always been a challenging topic within the IB curriculum. Admittedly, electrochemistry has not ever been my strong suit either, so this year I aimed to strengthen the unit with two additional demonstrations.
Providing Unique Learning Experiences
The February 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: metal–organic cage & host–guest interactions; safety; innovative teaching approaches; understanding kinetics; computer-based instruction; activities combining ethics and analysis; “play with your food” laboratories; synthesis and analysis in the laboratory; fluorescence-based experiments; chemical education research; mining the archives: copper.
Last winter I watched a webinar put on by ACS and AACT called "NGSS in the Chemistry Classroom." As a result of watching that webinar, I took an activity that had NGSS Science & Engineering Practices (SEP) integrated into it and tried it out in class. In this activity, students are required to develop their own procedures and data tables.
In this Activity, students investigate properties of radiation using a handheld radio.
In this Activity, students compare the properties of nitinol metal wire (known as "memory" metal) and ordinary wire.
In this Activity, students use an oatmeal canister to make a pinhole camera, load it with black and white photographic paper,
In this Activity, students remove tarnish from silver using the reaction of tarnish with aluminum.
As the raft of bubbles is stressed with the slider, dislocations move into and out of the grains and their boundaries.
