May 2022 Xchange

The May 2022 Xchange highlights 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. 

     

Nora Walsh has been using interactive notebooks for some time. Here she outlines her stoichiometry unit and explains how she uses the interactive notebooks with her students. Documents and foldable templates are provided.
     

The "Two-Faced" thionin reaction involves causing a purple solution to fade to colorless by shining light on the solution. I wondered if it could be demonstrated the color of light that caused this transition.
     

It can be frustrating when students are always on their phones. What if we meet them where they are at with some chemistry content? This is one teacher's journey into the world of Tik Tok.
     

Here is a quick way to use DocHub to update the formatting of the older AP Chemistry Free Response questions so it matches the new (2021) format!
     

Many chemistry teachers use models and diagrams to help students describe how matter behaves at the particle level. On April 14, 2022, Doug Ragan explained how he uses colored magnets in his classroom to represent things such as subatomic particles, states of matter, balancing chemical equations, types of bonding, molecular geometry and much more. View a recording of his presentation and access materials he uses. 
     

Flat, symmetrical molecules can be modeled by folding a sheet of paper, cutting patterns into the folded structure, and unfolding to produce the flat paper models. The finished models resemble paper snowflakes, but have a variety of rotational symmetries. Template patterns for several molecules are available for download in the Supporting Information.
     

Please welcome Phil Root as a new ChemEd X two-year college (2YC) lead contributor. This is his first blog. Enjoy...
     

A kaleidocycle is presented in which the entire periodic table has been collected. In this three-dimensional figure are the elements organized in four blocks according to their final electronic structure. It is intended that students with this playful figure actively participate in classes by rotating their kaleidocycle looking for the groups or elements that are being studied. The entire periodic table fits in one palm of their hands.
     

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