The color of a thermochromic system depends on its temperature. The colors of leuco dye-based systems can also be influenced by adding acids or bases to the thermochromic reactions. These can be used to create colorful demonstrations of acid-base chemistry. Thermochromism found in color changing cups can also be used to visualize heat flow, and therefore thermodynamic principles, associated with stretching and contracting elastomers.

A lab practical with an escape room story turned out to be a great final exam.
POGIL activities can be used to engage students in chemistry lessons through the use of student teams, effective models, and tiered questioning. Kristen Drury and Stephanie O'Brien presented in a ChemEd X Talk on April 21, 2021 and provided teachers with guidance on fostering student buy-in, student role formation, and POGIL implementation. Additionally, information was shared on how to assess students' participation in POGIL activities holistically and through individual examination of process skills such as communication, teamwork, and problem solving. You can watch the edited recording of their Talk here.

A couple of days ago on Twitter, the ever-lasting debate between lecture and active learning reignited due to some talks at an Educational Research Conference held in Dublin. These talks stated direct guidance (which includes lecture) was superior in terms of student learning due its reduction of students’ cognitive load. The main citation used for this argument was an article by Kirschner, Sweller, and Clark published in 2006. So, let’s dive into what this article says.
My top 5 reasons for using Green Chemistry in my classroom along with a few examples of replacement labs that follow Green Chemistry principles.
Lawrence Technological University’s Marburger STEM Center recently collaborated with students enrolled in the Media Communications Program to develop a new 30-min student film, Women Untold, which celebrates the important contributions of three women of color in STEM (science, technology, engineering and mathematics).
Given a guiding question, students determined what they wanted to test, did the experiment and got their CER boards ready for review. Instead of a regular argumentation session, we had a glow and grow session, where students had to provide positive and negative feedback for each board.
