Science Experiment: Energy with Popsicle Sticks

Presenter

• Stephen, Science Interpreter at the Franklin Institute

Experiment Overview

• Objective: Demonstrate energy transformation using Popsicle sticks.
• Materials Needed:
  • Popsicle sticks (also known as tongue depressors or craft sticks).

Procedure

• Popsicle Stick Weaving:
  • The sticks are woven together in a pattern known as "cobra weave."
  • This pattern can be learned online, with tutorials available on platforms like YouTube.

Key Concepts

• Elasticity of Popsicle Sticks:

  • Popsicle sticks are made of wood and are elastic.
  • When bent, they store energy and can "boing" back to their original shape.

• Energy Transformation:

  • Potential Energy:
    • Energy stored when the Popsicle stick is bent.
    • Referred to as potential energy because it is not yet causing movement.
  • Kinetic Energy:
    • When released, the stored potential energy transforms into kinetic energy, causing movement.

Demonstration

• Holding Energy:
  • Instead of using hands, other Popsicle sticks hold the bent sticks in place.
  • When one stick is removed, the energy release demonstrates kinetic energy.

Conclusion

• The experiment visually demonstrates the transformation of energy from potential to kinetic using a simple and easily accessible material like Popsicle sticks.

This experiment serves as an engaging way to illustrate core principles of physics like energy storage and transformation using everyday materials.
