Guide 5 Geologic Time Objectives
This guide’s quiz has four questions; one matching each objective.
Eons & Eras
Describe how researchers study early earth, including stratigraphy and geochronology; provide the approximate time span, geologic changes, and representative organisms of the Precambrian Supereon; and provide the approximate time span, geologic changes, and representative organisms of the Phanerozoic Eon, including the Paleozoic, Mesozoic, and Cenozoic Eras.
Tentative & Durable
Explain how scientific knowledge can be both tentative and durable, providing examples of knowledge that exemplifies both of these characteristics; provide examples of large reptiles that used to be classified as dinosaurs and now are taxonomically classified in different groups; and tell the dinosaur story including evolutionary origins, structural features, major taxonomic groups, new avenues of research, and theories for their extinction.
Fossils
Describe how a fossil forms; explain the types of information that can be determined from fossil evidence; and identify the common bones shared by vertebrates, including the significance of homologous structures in determining species relatedness.
Speciation
Compare and contrast forms of speciation, including examples and the role of genetic analysis in tracking speciation; explain what a living fossil indicates and how the rate of change can vary in different species over time; and distinguish between data, information, knowledge and wisdom and provide examples of each.

Complete all four sections and take the quiz on Canvas.
Use the learning objectives above to guide your studying.
Guide 5 Journal Assignment #9
Introduced in the Eons & Eras section of this guide:
Journal Page #9: Geologic Timeline
It can be challenging to visualize the massive intervals of time being discussed in the Precambrian Supereon and Phanerozoic Eon. For this journal page, you are constructing a timeline that shows the relative lengths of geologic time.
Include the order and relative lengths of the Precambrian Supereon and its three Eons (Hadean, Archaen, Proterozoic) and the Phanaerozoic Eon and its three Eras (Paleozoic, Mesozoic, and Cenozoic).
The Precambrian will be very long relative to the Phanerozoic Eon; you may need to have a creative way of looping the timeline. The eras are also different relative lengths.
This can be challenging, but an effective way to learn the order of geologic time. The time spans can be found through Wikipedia and other online sources. Be aware, they often don’t show the relative lengths, many illustrations shorten the Precambrian for convenience.
Guide 5 Journal Assignment #10
Introduced in the Speciation section of this guide:
Journal Page #10: Data to Wisdom
For this journal page you will be describing the process of transforming data to wisdom, including an example of the process.
First, describe in your own words what data, information, knowledge and wisdom are, and then describe the process of transforming data to wisdom using your own example. It could be something you have experienced, or an example you are creating.
You are turning in a journal page that includes:
- a description of data, information, knowledge, and wisdom.
- an example of the process of transforming data to wisdom.
Journal Page Directions
To be completed after taking the quiz on Canvas.
Upload your two journal pages to Canvas. If the file is really large, it may help to host it on a webpage and submit the web link to reduce upload time.
All three assignments are due by Friday 11:59 p.m. P.S.T. Once you have taken the quiz on Canvas and uploaded your two journal pages, you have completed this guide.
