This year national chemistry week saw section members making their 11th visit to the Paradise Elementry School in Las Vegas. Three classes of students in the fifth grade were the audience for our team of chemists. Dick Gaglione and Don Betowski were the organizers. The team consisted of 6 from the EPA laboratory, 3 from the UNLV student chapter, and the sections counciler and past chair.
