Simple formation of metal mirrors
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.
Organic nomenclature is usually taught as an introduction to organic chemistry. To help introduce students to organic nomenclature in a way that clearly summarizes the patterns that exist, a paper tool for naming hydrocarbons was developed.
This post addresses concerns about the quality of the future of chemistry education in an online environment.
The session begins by asking participants to discuss teaching dilemmas and identify those that have come up for them at their school or in their instruction. Participants focus on examining and commenting on their videos, specifically with regard to eliciting and advancing moves. They then learn about the advantages and purposes for taking a dialogic or an authoritative stance when probing students’ chemical thinking. Time is set aside to support teachers with adjusting or modifying their final formative assessment and receiving feedback from their peers before they give the FA to their students.
The goal for session 8 is to focus on the formative assessment enactment model. Teachers revisit the formative assessment enactment model and reflect upon its versatility and value for classroom use. This session uses videos of student discourse to help participants grapple with the critical aspects of the Formative Assessment Enactment Model. Participants explore a spectrum of teacher decision-making in the moment with regard to questioning students. Participants examine and analyze the following: eliciting moves; how to narrow or open up student responses; advancing moves; and whether to use directing or responding questions.
