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.

This final ACCT session will offer opportunities for participants to work collaboratively as we use the LASW protocol to review each of the final formative assessments that were given to students. Time will be spent reflecting on the ACCT course and engaging in discussion of the course objectives and components.
