This simulated ice core lab provides a great opportunity for students to use different units of concentration beyond molarity, explore how knowledge of chemistry can uncover past events on Earth and practice the skill of generating a calibration curve.
Nora Walsh outlines the interactive notebook pages she uses for her unit on Solutions. All of the documents and foldables are available for download.
This is the third post in a series dealing with seawater chemistry and global maritime trade. This classroom activity introduces the concept of salinity and tasks students to predict the range of salinities in certain regions of the ocean (coastal and open water, all four hemispheres, high and lower latitudes).

Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
Natural food dyes are being sold online and in stores that can be used as acid-base indicators. These dyes open up a host of possibilities for at-home and in-class. For example, these food dyes can be used as indicators in the quantitative titration of the Mg(OH)2 in milk of magnesia.
Boredom needs no explanation; we were all (Chemistry) students. A bored student is not an engaged student, and likely not a student who wants to learn. How can we make our lessons more engaging?
Assembling a large graduated cylinder with colored sugar solutions of various densities is described. By filling the cylinder in the reverse order from bottom up, very little mixing occurs resulting in an attractive classroom demonstration to illustrate density. Students also have to opportunity to practice density and dilution calculations.
In this activity, students learn about solubility and concentration. They watch videos that explain the dissolving process, how to calculate the molarity, supersaturation and how to make rock candy. They also use a PhET simulation to explore factors that affect the concentration of a solution.
A formative assessment designed by an ACCT cohort member designed to investigate student understanding of chemical control.
This activity goes beyond having students calculate concentration and dilutions. Students prepare a solution and the instructor can use a simple test to evaluate the result.
