February 2023 Xchange

The February 2023 Xchange highlights just some of the contributions that have recently been published on ChemEd X. We hope you will take a moment to check in and see what you may have missed. 

     

TikTok and YouTube Shorts are video sharing platforms for short-form, vertical aspect videos. Both of these services are growing more quickly in popularity compared to more traditional video formats. Josh Kenney shares some of the ways that he is using short-form videos in his chemistry class and shares a free resource (an exam review worksheet that links to a YouTube Shorts playlist through a QR code).
     

The Diet Coke and Mentos reaction is used as the basis for this hands on experiment. Students work in groups to research, test, and adapt as needed with the goal to get the highest possible geyser! 
     

Egg cartons and small objects such as milk jug caps or plastic eggs can be used to illustrate chemical concepts. The egg cartons can be cut into trays to represent atoms or to represent energy levels associated with atomic orbitals. The plastic caps or eggs distributed among the dimples of the trays can be used to represent electrons or pairs of electrons.
     

Teaching and learning the concept of limiting reactants can be challenging. In this activity students manipulate beads to learn about stoichiometry. A virtual drag & drop version is also available. 
     

This Nobel Laureate crossword puzzle focuses on prizes awarded between 1920 and 1930. Learn and revisit some historical chemistry, terminology and background on key historical figures in this field. This is our third in a series of Nobel Laureate crossword puzzles.
     

Highlighting this previously published post from June 2019 - This physical analogy relates to dynamic equilibrium and pits students against each other in a classroom-wide “snowball” fight. Not only is this activity great for building students’ conceptualization of dynamic equilibrium, it is also really fun!
     

ChemEd X invites practitioners in the chemical education community to share their experiences, knowledge and the resources they use in their classroom and laboratory.
