Hey there, curious minds! Welcome to Fizz Pop Wow, the super fun 5-Minute Science Podcast where we answer big questions with quick, exciting answers. I'm Michelle, and today's question is making a splash. Why does the ocean have waves? Let's find out!
The Science of Waves
Have you ever stood on a beach and watched the ocean waves rolling in? They crash onto the shore, then pull back, only to come back again and again. But where do waves come from? What makes them move? It’s not magic—it’s science! Most ocean waves are created by wind. When the wind blows across the surface of the ocean, it pushes the water, creating small ripples. As the wind keeps blowing, those ripples grow bigger and bigger until they turn into waves. The stronger the wind, the bigger the waves!
Try It Yourself!
Want to see how wind makes waves? Try this at home!
Try It Yourself!
Materials Needed:
- A large bowl or tub filled with water
- A straw
Steps to Follow:
- Fill a large bowl or tub with water.
- Use a straw and gently blow across the surface.
- What happens? The water ripples!
- Now blow harder. What happens? The ripples get bigger—just like ocean waves when the wind is strong!
Other Forces That Create Waves
Wind isn't the only thing that makes waves. Underwater earthquakes can create giant waves called tsunamis. The moon's gravity pulls on the ocean, creating tidal waves that rise and fall every day. Even boats and people moving through the water can make waves! The ocean is always moving, and waves help spread energy across the sea.
Your Challenge
Try the straw experiment and see how wind makes waves. The next time you're near water, watch how waves form. Are they big, small, fast, or slow?

Key Takeaways
- Most ocean waves are made by wind pushing the water.
- Stronger wind equals bigger waves.
- Other forces like earthquakes and the moon’s gravity also create waves.
