Members of IUP’s Student Affiliate American Chemical Society (ACS club) will present three chemistry demonstrations at the Blairsville Elementary Science Fair on Thursday, February 25, 2010, from 6:00 to 8:00 p.m. in the auditorium.
The very popular liquid nitrogen demonstration, which the club demonstrated at last year’s fair, is a favorite for all ages. Students last year were particularly impressed by a frozen banana used to pound nails into a board. A new demonstration this year includes “hot ice,” a liquid mixture of sodium acetate (make from vinegar and baking soda) that under the right conditions will make a solid crystalline material that looks like ice. The chemical reaction, however, is exothermic (heat-emitting), and therefore the “ice” is warm to the touch.
A third, hands-on demonstration will involve colored bubbles that can be used to make bubble art on paper for the kids to take home.
The ACS Club at IUP, which was formed in the 1970s, is comprised predominantly of students in Chemistry, Biochemistry, Biology, and pre-professional majors. Members provide free chemistry tutoring four days a week during the semester, raise money via fundraising activities that is donated to local school science programs ($1,000 each year), and hold or participate in community outreach activities such as National Chemistry Week in Pittsburgh, Mole Day, and local science festivals.
The club was recently awarded two Honorable Mention Awards by the National Office of the ACS for their achievements and activities during the 2008–2009 and 2006–2007 academic years.
