In this lab, students are presented with nine unknown substances. By performing a series of tests, analyzing chemical structures, and applying their understanding of how intermolecular forces affect the properties of a substance, students will ultimately determine the identity of each unknown.
Science Practice: Analyzing and Interpreting Data
Michael Jansen runs this engaging "big picture" lab on day 1 of Grade 11 Chemistry, which is the students' first dedicated Chemistry course.
This is a simple small-scale distillation that can be used several different ways.
Did you know that sand can be converted into a mixture of gases that spontaneously ignites in air? The procedures involved are relatively simple to perform, spectacular to observe, and relate to a rich assortment of chemical principles.

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.
Chad Husting explains how he used two hands on activities to get a sense of where his students were at within the realm of labwork and the scientific process as school began.
Michael Jansen reflects on a very common empirical formula lab that asks students to determine the empirical formula of MgxOy. He then explains how he continues to use it as a "successful failure", how he demonstrates an alternate procedure and leads his students to an important lesson.
A lab practical with an escape room story turned out to be a great final exam.
This classroom activity challenges students to figure out the volume of gaseous carbon dioxide emitted from the combustion of 1 gallon of gasoline fuel.
