The representation must be on a linear scale (not logarithmic) . Have the student to present the years in a way that really helps the audience to visualize just how long Earth has been around compared to how short an amount of time humans have been on earth, for example. 2. Have the student include a legend that allows the audience to interpret how they are representing the time since each event has occurred (e.g., 1cm = 1000 years, 1mL = 100,000

1. The representation must be on a linear scale (not logarithmic)

• . Have the student to present the years in a way that really helps the audience to visualize just how long Earth has been around compared to how short an amount of time humans have been on earth, for example.

2. Have the student include a legend that allows the audience to interpret how they are representing the time since each event has occurred (e.g., 1cm = 1000 years, 1mL = 100,000 years, 1 second = 10,000 years)

4. The student is to include the following important events:

• Start of life (~3.8 GYA^[1])
• Origin of eukaryotes (~2–3.5 GYA - your choice within that range)
• Origin of multicellularity (~2 GYA)
• Origin of Homo sapiens(~200 KYA)
• Present time (0 YA)

5. The student is to include at least 3 other events. The events must relate to the history of Earth, not human history. The student will need to find the dates of these events

• Formation of Earth
• Oxygenation of Earth’s atmosphere
• Origin of vertebrates
• Mass extinctions
• Origin of land animals and land plants
• Origin of mammals
• Origin and/or Extinction of dinosaurs
