Grade 8: Penny Lab

Students in Jen Chen’s Grade 8 science classroom have been learning about how metal ions give off unique emission spectra when heated. She also introduced them to the concept of why heated elements emanate colorful light. During remote learning, eighth graders watched a video to see what it looked like to burn copper compounds off pennies.
 
Upon resuming in-person learning, eighth graders were able to return to the lab where they learned how to use the Bunsen burners. As they heated pennies coated with copper acetate in the Bunsen burner flame, students were able to make first-hand observations of the characteristic green flame produced by copper ions.
