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.
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...
This is the second blog post describing a classroom activity relating seawater chemistry to oceanic shipping. Included are questions that challenge students to apply conclusions drawn from observations to making predictions.
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.
