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!
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.
Learn how to create cognitively demanding tasks for your classroom during this Knowles Academy virtual course.
For your enjoyment, we present lists of chemically-related words that end in the letters “-cation” but do not actually refer to the positively-charged chemical species. The lists are available for download in the Supporting Information.
Practice problem answer keys that provide correct and incorrect answers increase student metacognition and lead to more thorough learning.
Bring the fun of the viral word game "Wordle" into the chemistry classroom!
Recently, Josh Kenney took time from his regular scheduled chemistry curriculum to investigate a student's claim that chocolate cake was an acid-base indicator.
Tom Kuntzleman conducts a safer "mercury-like" beating heart experiment with an added splash of gratefulness.

Balloons that inflate using carbon dioxide produced from the reaction of citric acid and sodium hydrogen carbonate can be used to demonstrate a number of aspects of chemistry. Gas laws were used with the balloons to illustrate limiting reactants, molar mass of gases, and rockets. The endothermic reaction in the balloon was visualized with an infrared camera, and the Green Chemistry aspects of these balloons were considered.
