4a __describing various dating methods to determine the age of different rock structures.__

What do these GSEs mean? What subtopics do students need to address to understand these GSEs?
This GSE will help show students that by studying the age of rock structures, scientists can determine the shape, structure, pattern, and age of the earth. Fossils and other archeological evidence found in ancient rock structures can be used to trace patterns in Earth's history. With this GSE, students will use mathematical equations to determine the age of different rocks through three types of dating methods:
 * Relative Dating
 * Absolute Dating
 * Radiometric Dating


 * Types of Rock
 * Sedimentary
 * Metamorphic
 * Igneous
 * Earth Systems
 * Global Climate Change
 * Energy Transfer
 * Differential heating/convection
 * Production of winds
 * Oceanic currents
 * Atmospheric movements
 * Temperature and Precipitation changes
 * Wind and Water Reshape the Land
 * Erosion
 * Sedimentation
 * Glaciation
 * Deposition
 * Sudden Change
 * Gradual Change

What phenomena and representations help students understand these topics?

 * Study today's Weather, Temperature, Precipitation changes
 * Study today's natural catastrophes
 * Earthquakes, Volcanoes, Hurricanes, Tornadoes, Floods
 * Following the catastrophes
 * Studying the damage done/the after results of the storm?
 * How did the earth's rock formations change? Structurally? Physically?
 * Were there any fossils/archeological evidences found during these changes?

What activities or activity sequences can be used to address these GSEs?
