After studying about the Coriolis effect (the rotation of the earth that results in deflection of objects to the right in the northern hemisphere and to the left in the southern hemisphere) YME members created their own earth and put this theory to test. By inflating a large ballon YME members drew in the equator the north and south pole along with various countries. The globes ranged from the traditional with the 7 continents to the imaginative with Rolle’s Island and Wilson country. THE CHALLENGE - In pairs students were asked to have one person rotate the ballon just as the earth rotates as the other partner had to try and draw a straight line from the north pole to the equator and then from the south pole to the equator. In doing this it became clear that it was impossible to draw a straight line but rather the line would curve with the rotation of the “Earth”. The curvature of the line represented how objects suspended in air or water when traveling over a long distance would be impacted by the rotation of the earth. Understanding the coriolis effect was the first step to understanding the major wind patters on earth and how the wind then influences ocean currents and waves.
