Seawater Chemistry and Global Trade: Part 4

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

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).

What do we want to know about our students' thinking? Categorizing chemistry formative assessments with ACCT.

Formative assessment questions provide a useful lens into students' minds regarding what they are thinking about chemistry. By ascertaining what students are thinking, teachers can make decisions regarding what to do with what they learn. The members of ACCT (Assessing for Change in Chemical Thinking) presented a ChemEd X Talk on the topic on May 26th. You can watch the edited recording of this Talk and find more resources here.
