Using Interactive Notebooks in Chemistry - Stoichiometry

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.

     

Exploring The “Two-Faced” Thionin Reaction

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.

     

The Evolution of Social Media in the Chemistry Classroom

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.

     

Updating your AP Chemistry Free Response Format

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!

     

Making Chemistry Visible with Doug Ragan 

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. 

     

Paper Snowflakes to Model Flat Symmetrical Molecules

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.

     

An Educator’s Journey to Now…

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

     

Three-dimensional figure to improve the didactics of the Periodic Table

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.
