Title: Geologic Time - When Was Coal Formed?
Level: Middle/Secondary
Day/Time: One to two days, one day for research, one day to construct time line.
KERA Goals: 2.4, 2.6, 2.9, 5.3, 6.16
Objective:
The student shall construct a time line of geologic periods and label the major happenings in each. The student should pay attention to the climate and conditions during the coal forming periods.
Materials:
Background Information:
The students should have a general knowledge of epochs, periods and eras. They should make a chart similar to the one provided. Research can be done ahead of time by dividing the class into groups and give each group a period to research. This information can be added to the chart. Students should work in groups of two to construct the time lines. Be sure to have a large area (a long hallway is good) in which to work.
