Student Internet investigation that explores the subject of the geologic time scale; early, ancient and recent Earth history.
The activity is divided into three parts. Part one investigates the geologic timescale and how it is used to describe Earth's history. Part two explores the different life forms, evolution and geology of the Precambrian and Paleozoic time periods. Part three explores the Mesozoic and Cenozoic. The latest links containing images and data are presented as well for these topics. I use this computer lab activity for my Earth/Space class as part of the Unit V "Geologic Time" review but it can also be used as a high school level webquest review or as an introduction to the subjects. (Some students will finish the activity within one class period but generally it will take about an hour to complete.)
This activity as well as PowerPoint lessons, worksheets, review programs and assessments can be found under the Earth/Space Complete Unit V "Geologic Time" zip file folder.
