With quick set up and execution, Large Demonstration Electroscopes give educators more time to work with students.

• Affordable
• Electroscope Size: 77 cm
• Simple Assembly and Operation
• Zinc Plate Provided
• Topics Include the Photoelectric Effect and Einstein's Discoveries

The exciting demonstrations connect students to core physics and physical science concepts. Perfect for introducing a unit or as reinforcement after a lesson, these demos also explore the phenomena of the photoelectric effect and Einstein's extraordinary discoveries.

Rubbing the provided zinc plate with steel wool leaves a charge on the electroscope. When a strong UV light source (not included) is close to the plate, it frees the electrons, providing a fascinating viewing experience. Balloons are recommended but not included.
