Showing off her project, sophomore Hannah Brusca presents her mole to her fourth period class.

“I really wanted to do a Disney character and I wanted to do a princess who I like so I chose Rapunzel,” Brusca said “I did everything myself. The hair took over two hours and I learned how to hand sew.”

Chemistry students participate in mole day every year  during the week of Oct. 23.  The time and date are derived from Avogadro’s number, which is approximately 6.02×1023, defining the number of particles (atoms or molecules) in one mole of substance, one of the seven base SI units.
