ALLEGRA BOVERMAN/Staff photo. Gloucester Daily Times. Gloucester: During a PTO-sponsored enrichment program at Beeman Elementary School on Friday given by the Museum of Science. Museum educator George Pechmann supervises third grader Logan Weickowski as he burns a piece of flash paper in a Jacob's Ladder device. This device explains how air acts as an insulator, demonstrates how heat rises as the current creates the heat, and that sparks then turn into other kinds of energy.
