Students examine the concept of relative dating. They observe a teacher demonstration of geologic layers with a sandwich representing the various layers, analyze a cross section of bedrock, and create a drawing of a cross section of bedrock that includes an intrusion, extrusion, inclusion, and fossils.

Students understand the difference between relative and absolute location using the grid map as an example of an absolute location. They observe a class map showing longitude and latitude lines and learn that they provide exact locations. They then draw pictures of their homes, the classroom, or the way home. Full Review »

Students explore how to read fossil range charts. They develop an knowledge of the strengths and weaknesses of the fossil record. Students become familiar with the concepts index fossil and fossil range. Students use bar graphs to plot fossil ranges. They develop an knowledge of 'relative time' using fossil range charts.
