PIRA Code(s): 1L20.40 Set up time:5 minutes Operation: Remove pieces from the cone to show different conic sections. Physics and Science Concepts: Gravity Safety: Nails that connect pieces may be sharp.
PIRA Code(s): 1Q40.40 Set up time:5 minutes Operation: Place the train on the track. Plug the track into the variac and start the train by moving the dial. Physics and Science Concepts: Mechanics, Angular Momentum, Rotational Dynamics, Angular Momentum, Relative Motion Safety: Watch for sparks from the train. Maintain a cautious distance from the wheel.
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.
