In this lab, students connect the workings of an electrochemical cell in the lab with the symbolic equations used in electrochemistry and manipulate a model representing the particulate level of what is happening during the electrochemical process. Although this lab was previously highlighted on ChemEd X, there are now virtual options offered!
Many of us have molecular kits we only use once a year. Dust them off and find new lessons to use them in!
Melissa Hemling shares her favorite manipulatives along with cheap at-home alternatives to help students visualize VSEPR.
Ben Meacham decided to alter his approach to teaching about enthalpy and focus on getting students to first develop the mathematical model for enthalpy of solution so they could eventually apply it to make predictions for different solutes being dissolved. In this blog post he shares the process he used with his class.
March is Women's History Month and talking about female chemists' work during class is a great way to celebrate the month. Here, the author discusses three ways to highlight female chemists in a chemistry class.
The demonstration where CO2 is generated and used to snuff out a candle in an aquarium or other container is well known. This article describes a dramatic variation on these demonstrations that allows for discussion of such topics as the ideal gas law, densities of different gases, gas density changes with temperature, miscibility, and viscosity. The device described is easily and inexpensively produced and stored. The demonstration is large scale and works well for classrooms and community outreach events.
Infrared technology (FLIR Cameras) can be used to investigate intermolecular forces.
Per label, 39 grams of table sugar (sucrose) are in a 12fl.oz. can of a Red Bull beverage. Visually, how much is 39 grams of anything? Check it out in this post.
