Here is a great way to use spreadsheets to both collect student data and provide instant feedback during labs with quantitative data.
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.
Identifying Unknowns: Intermolecular Forces and Properties
Ben Meacham | Sun, 06/19/2022 - 14:21
In this lab, students are presented with nine unknown substances. By performing a series of tests, analyzing chemical structures, and applying their understanding of how intermolecular forces affect the properties of a substance, students will ultimately determine the identity of each unknown.

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...
ChemEd X Talk: Using a Digital Interactive Notebook in the Chemistry Classroom
Digital notebooking is a dynamic process that integrates different learning experiences to challenge and reinforce student understanding. This method actively engages students in a manner that encourages discussion and collaboration. We hope you will join us on July 14th at 8pm EST to learn how Sarah English uses digital notebooks with her students.
