Waves are caused by the transfer of energy - in this case ocean energy caused by the wind. We talked about wave parts and how to measure waves.
We discussed tsunamis and how countries around the globe are teaching native peoples to recognize the signs of a tsunami and setting buoys to measure if a tsunami is coming. Students decided that they were glad they didn't live somewhere where the threat of a tsunami is imminent... well except if the Canary Islands fall into the sea.
Last we discussed tides and their causes. Tides are caused by the gravitational tug of the sun and moon on the big wet mass of the oceans. The moon has a larger effect on the tides because it is much closer to the earth.
We finished the notes with Blue Planet Tidal Seas. We watched parts one and two to see tides in action and lifestyle of the organisms that live in tidal areas- both on the small scale from a sand bubbler crab's point of view and on a large scale. The Bay of Fundy in Canada has a tidal range from high tide to low tide of one hundred and fifty feet!
We finished the day with a "Where in the World Map Challenge." Here you can see Oneisha, Rick, and Stacey hard at work scrutinizing the map. In the background you can see TJ, Victoria, and Sharron also working hard. Courtney was the first person do, but Mariah, Mariah, Meg, and Michelle were the first group done. All received goofy prizes.
