The concepts of Measurement and Significant Figures can induce discomfort for both teacher and students. Michael Jansen shares his approach to teaching this important topic.
This activity allows for the simple and accurate determination of the heat of vaporization, ΔHvap, of water at 100°C, and ultimately the approximate strength of a hydrogen bond in boiling water, in kJ·mol–1.
There are many ways that assessment can be done well. Michael Jansen shares what worked for him.
Demonstrate the Law of Definite Proportions by quickly and easily preparing one or more esters!
Michael Jansen shares his thoughts about "softly" introducing topics before their formal appearance in the curriculum.
In this activity, students use their knowledge of thermochemistry to investigate a claim related to a kerosene fueled campstove.
Michael Jansen offers test taking strategies for students.
Try out this though-provoking capstone demonstration for the Chemical Reactions unit!
This activity allows for the simple and accurate determination of the heat of fusion, ΔHfusion, of water at 0°C.
From bond energies to thermochemical equations, explore the convergence of pathways to the same result in teaching Hess’s Law of Heat Summation.
