The present work describes a simple hands-on experiment kit for colorimetric quantification of ferric (III) ion (Fe[superscript 3+]) in an aqueous medium using anthocyanin extracted from "Ruellia tuberosa" L. as a green indicator. The extraction of a high amount of anthocyanin was easily accomplished by using only hot water instead of an…

Given that students are constantly communicating and documenting special experiences in their social and private lives with digital devices, we suggest that this behavior could be used to record and deepen learning experiences-such as visualizing reactions at the molecular level-in a chemistry class. An example would be the creation of stop-motion…
