Name:______________________________Period_________Date_____ Plate Tectonics or Does the earth move under your feet? The earth is a planet whose surface is constantly changing. In Alaska we experience many of the ramifications of this crustal movement. During our unit on plate tectonics we will explore how, why and when the earths crust changes. • You will be completing a 5-section lesson on plate tectonics. • Each of the lessons will take several days to complete. • The study will be assembled as a book at the end of the unit. • The first three sections will be done as a web quest: each section will be presented as a packet. • Upon satisfactory completion of the packet the next section will be made available. • You will be working in teams while doing the web quest but note each student needs to complete all portions of the quest. • We will be using the computer lab for part of the study. • Much of the material is also available in the class textbooks. • Books may be checked out for use if the Internet is not available to you at home.
