PIRA Code(s): 5C30.40 Set up time:5 minutes Operation: Jars can be charged with either the Wimshurst generator (5A50.10) or Van de Graaf generator (5A50.30). Charge Leyden jars in parallel and discharge, charge in parallel again and connect in series before discharging. The intensity of the sparks as well as their duration is much greater for the series connection. Physics and Science Concepts: Electricity and Magnetism, Capacitance Safety: Do not touch the charged capacitor. Make sure the jar is discharged before storing or touching.
PIRA Code(s): 6A20.45 Set up time:none Operation: Use the different types of mirrors to compare reflection. Physics and Science Concepts: Geometrical Optics, Reflection Safety: Do not shine bright light into mirror.
