Hi everyone! My name is Clarissa Sorensen-Unruh, and I am a new Lead Contributor/Blogger for the Two-Year College component of ChemEd Xchange. I am beyond thrilled, though, to join ChemEd Xchange and learn more about your interests on this platform. I am hoping you, as the audience, will help guide the topics I write about so that we can focus our discussions to interests both you and I share.
The history of the world is joined at the hip to the elements comprising the periodic table. The rise and fall of geopolitical empires, the quest to colonize new lands, the ballerina of regional and global diplomacy, the relentless exploitation of the natural landscape, and the driving force of world commerce past, present, and future- and not to mention what's in your refrigerator, pantry, on your person, and in your garbage can- all have the same starting point- the periodic table.
Have you ever seen the liquid nitrogen cloud? Do you wonder how the cloud forms when hot water is thrown onto liquid nitrogen? This post explores the liquid nitrogen cloud and possible explanations for its formation.
More students use YouTube than any other demographic. Considering this reality, I began creating my own video content on my YouTube channel, The Science Classroom. As a seasoned YouTube content creator, I offer tips for getting started with your own science tutorials.
Read Charlotte Allerton's career profile describing her background and her current position within Pfizer's Medicine Design organization.
In this activity your students will be introduced to the concepts of claim, evidence and reasoning. The activity is POGIL- like in nature in that no prior knowledge is needed on the part of the students.
For dynamic equilibrium, I like to use a physical analogy that pits students against each other in a classroom-wide “snowball” fight. Not only is this activity great for building students’ conceptualization of dynamic equilibrium, it is also really fun!
The solution to "Chemical Mystery #16: A Red, White, and Blue Chemistry Trick for You!" is presented. How this experiment can be used as a springboard to carry out a simple quantitative analysis of salt solubility is also discussed.
Watch this video and see if you can figure out how red, white, and blue colors can all be made from the same chemical solution!
Lawrence Technological University’s Marburger STEM Center recently collaborated with students enrolled in the Media Communications Program to develop a new 30-min student film, Women Untold, which celebrates the important contributions of three women of color in STEM (science, technology, engineering and mathematics).
