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.
If a student “gets the wrong answer” while performing mole conversions, it can be difficult (for both student and the teacher) to discern where an error was made. Inevitably sometime toward the beginning of learning these conversions, students can become overly confident, plugging numbers in without thinking about whether they are sensical. This card set slows students down to think about the order and purpose of each of the steps in mole conversions.
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!
Assembling a large graduated cylinder with colored sugar solutions of various densities is described. By filling the cylinder in the reverse order from bottom up, very little mixing occurs resulting in an attractive classroom demonstration to illustrate density. Students also have to opportunity to practice density and dilution calculations.
3DL4US: A New podcast explores the extension of three-dimensional learning to higher education. Many episodes are relevant for K-12 educators as well.
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.
