![]() ![]() If it is used by older students, it is possible toĬhange the Events and to divide them into three time intervals, such as This activity provides a good introduction to the Geologic Time Scale which has beenĪrranged (and developed) in a similar manner. Probably can place it between two events which you can remember. You probably cannot remember the exact year when that occurred, but you Think of another event which has occurred in your life. AnĮxample: I started Kindergarten at the beginning of Schoolian time, four years ago. See if you can describe a single event using the information in all three columns. Worksheet now resembles a complete time line for the events in your life. Preschoolian below the line and the word Schoolian above the line. In the first column entitled Time Interval, write the word The line took place after you started kindergarten and every event below the line took placeīefore you started kindergarten. Draw a horizontal lineĪbove the last event that happened before you started kindergarten. I started kindergarten four years ago, after I learned to walk but before I lost my first tooth.Ĥ) Now you are going to divide the events into two time intervals. Using both of these, describe when you started kindergarten. Now you can use both the sequential and the numerical information to describe events in These numbers are the numerical ages of the Guess and round off to the nearest whole year. These numbers in the column in front of each event. ![]() Then think of the number of years ago each event happened. In the middle column entitled, Numerical Time, placeĪ zero by today's date. Students describe events in their lives in a similar way.ī) Now, using sequential time, how could you describe when Tyrannosaurus rex roamed the earth?ģ) Return to your time line worksheet. Learned to ride my bike after I learned to walk but before I started second grade. ![]() Your completed list is now similar to what a geologist might refer to as a Sequential TimeĪ) You can use your own sequential time line to describe events in your life. For example: "When you learned to walk" could be written simply as "Learned to Walk".) (Students do not need to write out the entire event. Recent event is at the top of the list and the event that occurred first is at the bottom of the list. Order in the third column, Sequential Time, but you will be writing them so that the most Order, by placing the number 1 in front of the event that occurred first in your life, a number 2 for the second, etc.Ģ) On the worksheet entitled Your Personal Time Line, you will be writing these events in (click here to download a pdf version)ġ) Look at the events listed on the sheet entitled Events in Your Life. ![]() This activity will help students to understand the methods used by geologists in creating theġ) Students will place events in sequence and assign relative times to each event.Ģ) Students will gain an understanding of relative and numerical time.ģ) Students will become familiar with the methods used by scientists to develop the GeologicĮxplore this link for additional information on the topics covered in this lesson:ġ) Each student will need: A copy of the worksheet Events in Your Life.Ģ) A copy of the sheet Your Personal Time Line. Make sense out of the enormous expanse of time that has elapsed since the origin of the earth. TELLING THE history of the earth requires placing events in sequence so that reference canīe given to the relative and/or numerical time at which each event occurred.
