4. What is a Wave? Wave: The Movement of energy through a body of water Most waves form when winds blowing across the water’s surface transmit their energy to the water

5. Wave Properties Wave Size: Waves start in open ocean The size of wave depends on: 1.Strength of Wind 2.Length of blowing 3.Distance

8. Parts of a Wave Crest Trough Wave Height Wave Length Frequency

9. Parts of a Wave What would the wave look like if you shortened the wave height? Made it higher? What would the wave look like if you increased the wavelength?

11. Breakers Near the shore, wave height increases and wavelength decreases Friction between the ocean floor and water causes waves to slow down and the shape to change This is called “Breakers” The Blue Planet: Episode 1 Video (Netflix)

15. Circular Motion of Water Particles Water particles don’t move very much due to waves (we’ll talk about how they move far when we get to currents) Water particles move in a circular motion They move forward slightly, then down and around with the wave This circle gets smaller with deeper water Hallway Demo!

17. What happens when waves run into each other? When a crest and a trough of 2 waves run into each other, they cancel out, which makes When a crest and a crest of 2 waves run into each other, they make a bigger wave Rouge Waves National Geographic Video

18. The Science of Surfing Catching the Biggest Wave: National Geographic Video How could you use science in your daily life?
