Welcome to the Chemical Education Xchange (ChemEd X)! We hope to strengthen the community of chemistry educators by providing learning resources and forums for discussion and collaboration on our interactive platform. Take a look, and join in.
Check out the schedule for upcoming ChemEd X Talks and ChemEd X ChemBasics Talks along with recordings of past events.
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.
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).
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.
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!
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.
Some metals and metal alloys undergo a transition to brittleness at cold temperature. This phenomenon likely contributed to the demise of the Titanic.
