This lab guides students through taking data and constructing their own heating curve for water. It requires no special equipment, is low prep, is safe, and can even be done at home for homeschool or distance learning. Even though the lab activity itself is relatively simple and straightforward, the concepts still engage students in higher level thinking and gives them important practice with laboratory techniques and forming hypotheses.
Science Practice: Obtaining, Evaluating, and Communicating information
Use a simple experiment to get to know students, demonstrate experimental design and discuss classroom policies about cell phones.
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.
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.

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.
The Golden Drain is a case study developed by Sharma and Wolfgang where students work to uncover a company’s lost revenue due to the error of a new employee.
