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.
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. If you would like to learn more, please join us for a ChemEd X Talk about formative assessment question categories that we will be leading on Thursday May 26 at 7:00 PM EST.
Rajasree Swaminathan has developed a series of books that combines story-telling and visual representation of the elements as human characters. Along with hands-on activities, these books have created enthusiasm in her chemistry classes.
