Name: _________________________________ Date___________________ Period: _________ Geological Time Scale Before beginning the study of the Earth, geology, we must first understand and comprehend the time scale of the Earth. We all know the origin of the Earth precedes us by approximately 4.6 million years. However, that time scale is too large for most of us to comprehend. In order to better understand this enormous time scale you are going to construct a metaphorical time scale. Directions: Design a time scale of Earth which will include all 4.6 million years of Earth using a unit much smaller than million years. Basically, we are going to be squeezing all 4.6 billion years into a small comprehendible time scale. You must include a minimum of 15 events or important dates on your time scale. Events can include geological eras, important dates, and personal dates. Examples of metaphorical time scales include 1 football field, 1 day, the length of this room in blocks, 1 city block, mass, volume, etc… Be original and creative!!! Example: In this example I am going to create a metaphorical time scale of 1 football field. Basically, I am going to squeeze all 4.6 million years, and there events, into 1 football field. The event I am going to include is the age of humans (approximately 100,000 years ago). Known Age of Past Event = Unknown Time Scale Metaphor Known Age of the Earth Maximum Measurement in Metaphor (100,000 years) = (X) 1st human on football field in yards (4,600,000,000 years) 100 yards (100,000years)(100yards) = (X yards)(4,600,000,000 years) 10,000,000 4,600,000,000 X = .002 Yards You must create a visual representation of your time scale. You may use items such as construction paper, toilet paper, popsicle sticks, tooth picks, pens, toys, etc.. We are going to hang these in the room. Make sure they are creative and look nice! Here are some important dates in Earth’s history. However, you may also use your own.
