Experiment

Sound Waves and Vibrations (Part 3)

What You'll Learn

Waves transfer energy without transferring matter. Transverse waves (like light) vibrate perpendicular to the direction of travel. Longitudinal waves (like sound) vibrate parallel.

Key Words

  • observation
  • conclusion

Materials Needed

  • cardboard
  • tape
  • scissors
  • straws
  • paper clips

Safety First

  • Work in a well-ventilated area when using vinegar or other strong-smelling substances.
  • Dispose of materials properly after the experiment.
