The Devil's Milkshake is a simple, yet interesting chemistry experiment that fits well as a Halloween demo.
Erica Jacobsen shares highlights from the February 2018 issue of the Journal of Chemical Education.
During our “Periodic Table and Periodicity" unit, we take about 3 days to learn the content and another 3-4 days to practice the content (more for Chemistry 1, less for Honors). One way that I have my students review the content is by playing a board game that I recreated from an NSTA conference a few years ago.
Students will proceed through a pre-lab engagement activity, organize element cards based on similarities & trends, discuss trends with the class and then produce a periodic table that includes the trends discussed within the lab.
