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.
Student: "Why do I have to take this chemistry class?" Heard it before, perhaps numerous times right? Let's see what an astrophysicist has to say about this ubiquitous student question.
Maritime shipping is the backbone of global commerce and trade. How is the chemistry of seawater involved in the complex, intertwined network of international trade? Let's find out.

"Make it Stick" is filled with research-based recommendations to improve the effectiveness of learning.
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.
The major component of a non-carbonated drink such as KoolAid or a similar beverage is usually a fruit acid, either citric acid or malic acid. The titratable acid (H+) concentration of such drinks has been found to be in the range of 0.02 to 0.04 M. A weak acid-strong base titration of these drinks with 0.1 M NaOH solution is feasible as a student exercise. The use of such drinks as reagents is safe, convenient, and inexpensive. Experiment instructions are included.

This engaging activity uses wrapped and unwrapped candy to simulate alpha and beta decay.
In this blog the author describes how three components of a water tower reservoir is analogous to an acid-base buffer system.
