Collisions - Chemistry Learning Games for High-School and College Students with Jen Lee

Collisions is a system of eight digital games, grounded in the rules of chemistry, that can be used to introduce, teach, and review more than 50 key concepts in your chemistry classroom. Collisions makes abstract concepts tangible by allowing students to visualize and manipulate the building blocks of matter, while providing a safe space to make mistakes and learn by introducing content through gameplay. On March 24th, 2021, Jen Lee presented a ChemEd X Talk about how instructors can use these games with their high school and college students. Besides explaining how the games work and interconnect, she outlined how to find and use premade lesson plans and answered questions posed by participants. You can watch the edited recording of Jen's Talk here.

Energizer Lab with Virtual Options

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!

Teaching, The Best Kept Secret!

This Zoom presentation (= free registration) will share strategies and resources for communicating the facts about the teaching profession so students have accurate information about career prospects. Can't make it? Feel free to share this information with a colleague (or two).

The Carbon Dioxide Spiral Staircase

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.
