This course covers Measurement, the Theory of Plate Tectonics, Earthquakes and Volcanoes, and the Water Cycle. Measurement, the process of quantifying observations, is one of the cornerstones of science. Students develop an understanding and intuitive feel for the metric system. They learn how to use the appropriate tools to measure length, mass, liquid volume and temperature, and acquire the vocabulary associated with metric measurement. Students begin their study of Earth’s Interior and the theory of Plate Tectonics by building a model of Earth that depicts its surface creatively and interior layers to scale. They learn about the formation, movement and subduction of Earth’s plates, and why earthquakes and volcanoes occur along certain plate boundaries. Students develop and use their mapping and graphing skills to identify the more prone locations of earthquake and volcanic activity worldwide. They also look at the impacted communities and how they prepare for and sustain such potentially disastrous events. Students design and build a three-story “earthquake resistant” structure and test it on a specially designed shake board. Lastly, students learn about the Water Cycle and the ongoing need for clean drinking water in less developed countries. They design a water filtration system and propose solutions to bring greater attention to this crisis.
