This is a relatively short unit in my course and as a result, I only use two spreads for it. I have two fully developed spreads to share, with optional bonus material you could add on to the first and an alternative layout for the second that includes colligative properties.

Recently, Anne Schmidt and I published an article together in the Journal of Chemical Education.1 The article outlines a titration activity that students can carry out at home using only store-bought items. The objective of the activity is to determine the amount of Mg(OH)2 in milk of magnesia.

Demonstrating the densities of various liquids (oils, alcohol, detergent, syrup, etc.) in a tall glass container is a popular at-home science activity described on many websites.1-3 Colored sugar solutions of varying concentrations can similarly be layered to illustrate density and generally require the lower density solutions to be care

The “Exploring Concentration” formative assessment (FA) asks students to make their “ideal” Kool-aid solution and to make variations of their recipe to explore the different variables of concentration. This FA targets chemical control by allowing students to experience the processes and effects of changing concentration.
