Electrostatics Kit Simple PSSC for Static Electricity Experiments

Description

The Electrostatics Kit Simple PSSC, also known as a basic electrostatics experiment kit, PSSC static electricity kit or electrostatic charging demonstration set, is designed for investigating fundamental electrostatic principles through practical physics experiments. Manufactured by IEC (Industrial Equipment & Control Pty Ltd), this Australian-made educational kit contains a selection of plastic strips, rubbing cloths, polystyrene balls and supporting accessories for demonstrating electrical charging and electrostatic forces. The kit follows the Physical Science Study Committee (PSSC) approach, supporting hands-on investigations where students observe the behaviour of charged materials and draw conclusions from experimental results.

The supplied five transparent acrylic strips and five vinyl strips allow students to investigate how different insulating materials develop electrostatic charges when rubbed with suitable cloths. The two woollen cloths are particularly useful for charging vinyl strips, while the two cotton cloths are used to charge acrylic strips. The resulting charges depend on the materials and experimental conditions. Students can suspend charged plastic strips and position another charged strip nearby to observe electrostatic attraction and repulsion. These experiments introduce the behaviour of like and unlike electrical charges.

The kit includes nine polystyrene balls that can be prepared for use as lightweight conductive demonstration spheres. A supplied 25 mL bottle of graphite-in-alcohol coating creates a conductive film on their surfaces. Once the graphite coating has dried, the balls can be suspended using the supplied 3.5 m nylon filament. Their movement provides a visible indication of electrostatic forces acting between charged objects. The six polythene insulators, measuring 130 × 10 × 3 mm, support the preparation of demonstration arrangements and help reduce unwanted electrical conduction between components. Six wooden clothes pegs provide convenient supports for holding the insulating strips upright during experiments. Five pins and a small paintbrush assist with preparing and coating the polystyrene balls.

The kit also supports investigations of electrostatic induction, where nearby charged objects cause electrical charges to redistribute within conductors without direct contact. For these experiments, IEC specifies two 200 mL glass beakers and two 150 mm metal rods as additional equipment. These items are required separately and are not included in the kit. Students can observe how a charged plastic strip influences the charge distribution of metal rods supported on insulating glass beakers. The manufacturer’s instruction sheet describes three experiment sequences, including charged plastic strips, suspended polystyrene balls and electrostatic induction using metal conductors. The kit is supplied in a 350 × 250 mm bag and weighs approximately 270 g, making it convenient for classroom storage and practical laboratory activities.

Effective electrostatic demonstrations require clean, completely dry materials. Surface moisture, oils and contamination can reduce charge retention and make experimental results less consistent. Safety Precautions: The graphite coating contains alcohol and must be kept away from heat, sparks and open flames. Use adequate ventilation and allow coated components to dry before experiments. Sharp pins and any cutting tools should be handled under appropriate supervision. Each kit contains 11 types of components, as detailed below. Additional laboratory equipment required for certain experiments must be supplied separately.
