Nora Walsh reflects on her experience using phenomena in her chemistry courses and assessments for the first time.
Part 4 of Colourful Chemistry of Canning explores how to make gold in an old tin can!
With a little chemical investigation, you can figure out how Jet-Puffed's new color changing marshmallows work!
Part 3 includes further anthocyanin experiments to make a connection between the food we eat and the chemical principles that are employed to ensure that canned foodstuffs can be preserved properly. These recent studies have focused on the reaction of tinplate cans with iodine.
Ariel Serkin shares an activity she has explored using natural acid base indicators with her food chemistry elective students.
Laser cutters can be used to cut and engrave a variety of thin materials. Compact discs, composed of layers of polycarbonate plastic and aluminum metal, were explored for their ability to be shaped with a laser cutter. The laser can successfully cut and engrave the compact discs into the shape of snowflake. However, each disc must first be coated with a material like glue in order to protect the plastic from discoloration and the byproducts from cutting the plastic that can accumulate on the disc surface.
Diffusion of HCl(g) from concentrated solutions of HCl can be used to illustrate some chemistry related to the train accident in Ohio.
This activity is an interesting way to engage students before formally beginning the study of Thermochemistry. Students experiment and compare the use of 1% milk and half & half cream in coffee.
Part 2 includes further anthocyanin experiments to make a connection between the food we eat and the chemical principles that are employed to ensure that canned foodstuffs can be preserved properly.
This Pumpkinator is a fantastic orange-to-blue-to-orange chemical reaction that will make a great addition to your Halloween-themed chemistry demonstrations.
