The May 2018 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: electrochemistry and corrosion; textbooks; research on the chemistry teacher pipeline, argument-driven inquiry, and online homework; using everyday objects to teach; teaching organic chemistry with games; communication and writing; examining and creating innovative curriculum; computer-aided discovery activities; exploring kinetics; interdisciplinary laboratory investigations; from the archives: applications of 3D printing for teaching chemistry.
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. Students compare the abilities of conductive and dielectric materials to attenuate or block, radio waves, and compare the attenuation of AM versus FM radio waves. The radio is placed inside different objects and students record which materials blocked or attenuated the waves.
In this Activity, students compare the properties of nitinol metal wire (known as "memory" metal) and ordinary wire. Using the observed properties, they design (and possibly make) a toy that would use memory metal to operate. This Activity connects toys with science, and allows students to become inventors as they design a toy of their own.
In this Activity, students use an oatmeal canister to make a pinhole camera, load it with black and white photographic paper, and create a paper negative using the camera. This interdisciplinary Activity combines chemistry and art.
In this Activity, students remove tarnish from silver using the reaction of tarnish with aluminum. If only untarnished silver items are available, students first tarnish them using items that contain sulfur. This Activity could be used with topics such as chemical changes, metals, electrochemistry, and redox reactions. The Activity could introduce a discussion of silver and its reactions.
As the raft of bubbles is stressed with the slider, dislocations move into and out of the grains and their boundaries.
