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.
Bill Hammack, Michael Faraday, and the timeless beauty of the science behind the combustion of a candle. "There is no more open door by which you can enter into the study of science than by considering the physical phenomena of a candle," Michael Faraday.
The June, 2018 issue of the Journal of Chemical Education contains an article that describes a simple, yet fascinating experiment that you and your students are going to love! It involves the use of butterfly wings from the genus Morpho. I obtained some of these wings and enjoyed experimenting with them. You will too!
Simple methods to prepare liquid air are described. In addition, ways to test the properties of liquid air and other liquefied gases are explored.
Density Bottles can be used to teach a variety of chemical concepts such as density, solubility, and polarity. In this post it is shown that Density Bottles can also be used to differentiate between heterogeneous and homogeneous mixtures, and to explore light scattering.
Augmented reality is a type of technology that uses an app to turn a hidden QR code into a three dimensional object on a screen as viewed by your camera. Elements 4D attempts to bring augmented reality to chemistry.
I will share how I use the Target Inquiry activity, Change You Can Believe In. I have realized that I need to include particulate models within the assessments after the lab to fully evaluate my student's conceptual understanding.
You probably know what happens when you place dry ice in water. Do you know what happens when dry ice is placed in acetone or glycerin? Read this and find out!
The purpose of a lab practicum is to assess a student’s understanding of the content by completing a hands-on challenge. These assessments focus more on problem-solving skills than technique.
This exercise is intended as an ice-breaker for a first or second class meeting. It also serves as an introduction to physical & chemical properties and application of the macro/micro/symbolic representations of chemical phenomena. Finally, it also provides a framework to mention many of the topics to be covered in a general chem first semester course.
