Wind and Waves: How Does Wind Create Waves?

Ages 6-1210-15 minutesEasy Difficulty

About This Activity

Explore how wind creates ocean waves by blowing across the surface of the water, simulating the forces that shape the ocean.

Materials Needed

  • A large bowl or tub
  • Water
  • A straw

Safety Notes

  • Be careful not to spill water on slippery surfaces.
  • Avoid inhaling water through the straw.

Instructions

  1. Fill a large bowl or tub with water.
  2. Use a straw to gently blow across the surface and observe the ripples.
  3. Blow harder and see how the ripples grow into bigger waves.
  4. Experiment by changing the angle or strength of your breath to see different wave patterns.

How It Works

When wind blows across the ocean, it pushes the water and creates ripples that grow into waves. The stronger the wind, the bigger the waves, just like in this experiment where your breath mimics the effect of the wind on water.

Tips for Success

  • Try using different-sized bowls or tubs to see how the waves change.
  • Use a fan instead of a straw for a continuous wind effect.
  • Observe real-life waves in a lake, pond, or bathtub and compare them to your experiment.
