Some explorations and explanations regarding superconductors and the quantum levitation (also known as quantum locking) experiment.
During the last few semesters, a small survey has been deployed at Bradley University where students were to describe and classify items of litter that they found. The purposes of the surveys were to get students thinking about some of the chemical implications of solid waste and give the students some experience with a citizen science project. The most recent iteration of the survey, and some of its results, are described.
After teaching the concepts and calculations for acid and base strength, concentration, percent ionization, and pH I noticed many of my students were struggling to make meaningful connections between these calculations.This lesson was created to strengthen the understanding of the relationships between these concepts and skills.
The May 2021 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: teaching biochemistry, assessment, learning to think like a scientist, environmental chemistry, forensic chemistry, surface chemistry, solution mixing, organic chemistry laboratory experiments and activities, computer-based experiences, research on promoting student success, from the archives: systems thinking.
Beautiful, metallic mirrors of copper or silver can easily be formed in test tubes. Simply add the appropriate metal salt to a test tube, and heat! These reactions should be performed in a fume hood.
To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist in the IUPAC system, a series of paper tools were developed. The paper tool in this activity can be used to introduce the IUPAC naming of major classes of organic compounds. These paper tools are easy to print and distribute to every student each semester.
In order to teach chemistry effectively, we must ascertain what our students are thinking about chemistry and make a decision regarding what to do with what we learn. Formative assessment questions provide a useful lens into students' minds regarding what they are thinking about chemistry. Let us consider then, how categorizing formative assessment questions could help us plan out our classes more deliberately, in order to better design purposeful written formative assessments that align with our curricular goals.
Evaluations are part of everyday life. This multi-part blog has aimed to expand the collective understanding on what is evaluation and what are some ways that it is done.
This year so many in-person events at school have not been able to happen due to COVID restrictions. One activity that the author's science honor society students have enjoyed greatly is the Skype with a Scientist Live sessions. Students register in advance and then have the opportunity to be face to face with a scientist.
This post describes a simple way to generate blue, green, orange, and yellow copper complexes, and to use these complexes to introduce students to the effect of temperature on chemical equilibria. The protcol avoids the use of caustic agents, allowing the experiments to be conducted by students as a laboratory-based investigation.
