You can perform an orange to black chemistry demonstration using materials commonly found in stores. The reaction appears to be similar to the Old Nassau reaction, but uses greener reagents. This is a great demonstration to do around Halloween time.

In this blog, lessons learned and strategies for utilizing choice boards in chemistry classroom are discussed.
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.
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.
Are you having a hard time describing 3-D drawings or or showing motion of particles in your digital assignments? GIFs can help!
Chad Husting presented in a ChemEd X Talk and spoke about how he has transitioned to standards based grading during a pandemic! He shared some tips that have solved many of the problems that teachers struggle with including having a mix of face to face and virtual students and keeping up with late work, make-up work and missing assignments! You can watch the edited recording of Chad's Talk here.
Have you seen the rainbow candy experiment? It's a very simple experiment that involves pouring water into a plate that has M&M's candies or Skittles arranged in a pattern. Very curious shapes of sharply divided regions form spontaneously. How does this happen?!
