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.
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.
Can Alkaline Water Change the pH of your body? We use chemistry to put this claim to the test!
In this blog the author describes how three components of a water tower reservoir is analogous to an acid-base buffer system.
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.
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.
