samples on the basis of color, mineral composition, and texture. Lesson 22: Students explore rates of crystalline Exploring Igneous texture, how three of the previous Rock Formation rocks have formed. Students review the rock cycle. Ash has constructive and Lesson 23: Students collect data on the destructive effects. Volcanic Ash properties of ash, including its hardness, settling rate, magnetism, texture, and appearance. Ash fall affects local and Lesson 24: Students design their own global weather. Effects of Ash experiments to simulate the eruption Fall of pyroclastic ash. They examine the constructive and destructive effects of ash fall on humans, the environment, and global weather. Tornadoes, hurricanes, Lesson 25: Students carry out an investigation in earthquakes, and Volcanoes which they explore the effects of ash volcanoes are examples of Assessment fall on the temperature of the Earth’s natural catastrophic surface. They must control variables, events. Where and why set up a data table to collect these natural catastrophic temperature and time data, record events occur reveals observations, graph data, and draw information about the conclusions that relate to concepts in Earth’s processes. the module. Students complete a series of thinking questions about Part 3 concepts. Students complete a post-module assessment that matches the assessment from Lesson 1.
