1.Students read information on the Precambrian period and see example answers to the worksheet. This enables them to see what is required and become research readers. 2.Find information, asked on the worksheet, on three periods in Earth's History. 3.Re-write the information on three index cards. Place index cards on a time line that stretches across a classroom wall.
Students can be creative with their representation of each period.
They are not limited to index cards. However, the index cards provide the opportunity to consolidate their notes and better understand it. Edward Colley teaches science at Murry Bergtraum High School in Manhattan.
