Student Internet investigation or "webquest" that explores the subject of Earth's oceans, chemical make-up, currents, waves and tides.
The activity is divided into three parts. Part one investigates the origins of Earth's oceans, chemical properties and the process of desalinization. Part two explores the Coriolis Effect, surface & density currents and how it affects Earth. Part three discusses ocean wave formation, ocean water movement and how tides are formed.
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 VII "Oceans" review but it can also be used as a basic 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 VII "Oceans" zip file folder.
