Michael Jansen runs this engaging "big picture" lab on day 1 of Grade 11 Chemistry, which is the students' first dedicated Chemistry course.
In recent years, the fluorescence properties of pumpkin seeds have been highlighted on social media. When illuminated with a UV lamp, pumpkin seed extract appears orange/red to the human eye due to fluorescence associated with protochlorophyllide that is present in the seeds. Chlorophyll extracts can also be used as a fluorescent dye in “glowstick” chemiluminescence experiments. The similarities between chlorophylls and protochlorophyllide raised the question, is it possible to use pumpkin seed extract as a fluorescent dye in chemiluminescence experiments? In this short article, some results are reported from attempts to use pumpkin seed extracts for chemiluminescence experiments.
Engage your students with this stoichiometry scavenger hunt!
Finding demos related to nuclear chemistry that are interesting, relevant, and manageable is challenging. Melanie Harvey is both a chemistry professor and a ceramic artist. Using Fiestaware to talk about the historical use of radioisotopes is one of her favorite demonstrations.
