I had the opportunity to develop an advanced chemical lab design course for a small group of ambitious students. I have outlined the resources I used and how I pulled the course together,
Science Practice: Asking Questions and Defining Problems
If you are looking for ideas to create an authentic opportunity for students to apply their knowledge of gas laws while integrating some of the most important science practices, then this activity may fit your needs.
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.
Erica Jacobsen shares highlights from the June 2019 issue of the Journal of Chemical Education of special interest to our ChemEd X community.
Biosorption is a method that can be used for the removal of pollutants from wastewater, especially those that are not easily biodegradable. This experiment uses citrus fruit peels as part of a iodometric titration to conduct a wastewater treatment binding copper.
This strategy has been very helpful in establishing relevance to topics taught and in making connections between topics taught within a unit. It also provides a way for students to ask questions and make written explanations of phenomena, which are “Science and Engineering Practices” of NGSS.
The summer is an ideal time for reflection, a time to process and grow as an educator. This summer I was fortunate enough to attend the POGIL® National Meeting at Washington University in Saint Louis as well as assist as one of the facilitators at the Northeast Regional Meeting at Manhattan College. While there are numerous ways to spend your summer vacation, I wanted to share some reasons why POGIL® draws me in time and again.
In an effort to align my lessons with the Next Generation Science Standards (NGSS), I have tried to take the content I have traditionally taught, and shift the design to focus on student engagement with the science and engineering practices outlined in the standards. For the topic of heat transfer I re-packaged the ice melting blocks discrepant event as a NGSS investigative phenomena.
Whether you are looking to add a bit more scientific inquiry to your labs or simply looking for a great stoichiometry lab that can be added to your collection, I encourage you to try something like this with your students!
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.
