Seawater Chemistry and Global Trade: Part 4
Scott Donnelly | Wed, 06/22/2022 - 14:32
Continuation of the practical application of chemistry to seemingly something unrelated- global maritime trade. In this classroom activity students predict the buoyancy (and hence stability) of a merchant cargo ship based on interpretation of seawater surface salinity values. Like in the first three posts, the question types are conceptual.
Seawater Chemistry and Global Trade: Part 3
Scott Donnelly | Sun, 06/12/2022 - 15:36
This is the third post in a series dealing with seawater chemistry and global maritime trade. This classroom activity introduces the concept of salinity and tasks students to predict the range of salinities in certain regions of the ocean (coastal and open water, all four hemispheres, high and lower latitudes). Enjoy...
Lessons from the Early College High School Model
Josh Kenney | Thu, 05/19/2022 - 12:13
Early Middle College High Schools are growing in popularity. They are an alternative public high school program where students earn up to 60 college credits while completing their high school diploma. Here, the author describes some lessons learned while teaching at an early college program that helps prepare students for college and careers.
Can Alkaline Water Change Body pH?

Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
Too Hot to Handle? Hydrogen Reacts with Oxygen on Palladium Foil
Dean Campbell | Thu, 04/28/2022 - 20:50
The reaction of hydrogen and oxygen gases to form water is well known to be an exothermic reaction. That reaction can occur by first absorbing the hydrogen into palladium metal, and then placing the resulting palladium hydride into contact with oxygen in the air. Infrared and visible light videos were recorded for this process involving palladium foil, and the Green Chemistry and safety aspects of these activities are considered.
The Evolution of Social Media in the Chemistry Classroom
Chad Husting | Tue, 04/19/2022 - 14:29
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.
Exploring The “Two-Faced” Thionin Reaction
Tom Kuntzleman | Tue, 04/19/2022 - 11:44
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.
Updating your AP Chemistry Free Response Format
Melissa Hemling | Fri, 04/08/2022 - 10:40
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!
Paper Snowflakes to Model Flat Symmetrical Molecules
Dean Campbell | Wed, 04/06/2022 - 13:39
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.
