Julia created a model of the earth with all of its wind patterns and even a hurricane for her chapter challenge construction foreperson. She showed and explained the trade winds, jet streams, Coriolis effect, easterlies, and westerlies. She explained the trade winds are winds between the equator and 30 degrees latitude. The westerlies and easterlies are between 30 and 60 degrees latitude.The jet stream is a river of air that goes over America and Canada coming from the west. She also portrayed hurricane Irene and explained that it was a category three storm during its time near Florida. She made her model out of clay on a styrofoam ball. She even colored the clay herself.
Aaron showed us how cold air goes under warm air and how to make a cloud in a bottle for mini lab master. In the fronts lab, he put a blue ice cube in warm water and then put in red food coloring. The ice dropped because the cold water is more dense and it dropped below the less dense warm water. That proves that a cold more dense front will force up a warm less dense front. He also showed how to make a cloud in a bottle. He put warm water in a bottle and then put in matches. The water then condenses at the top like a cloud. Then he opened the bottle, releasing a cloud.
Rachel created a power point about the atmosphere for wild card. It included the layers of the atmosphere: the troposphere, stratosphere, mesosphere, thermosphere, and the exosphere. She also talked about aerosols which are particles of dust, salt, pollen, and acids that wind moves around the air. Rachel’s presentation concluded with a quiz. Team 2 defeated team 1 in the quiz by a large number due to there tremendous bell ringing ability and their knowledge of the power point and chapter. They won the glory of winning and of course bragging rights.
