This is a two day project: One day research-collect, one day build

• As a group we will all be building a timeline of the Earth's Geologic History.
• We looked at these types of timelines in our previous lesson on Geologic Time

 

Day 1: Research: build your list of 20 key events that occured during the period you choose, print out 15 images to attach to the timeline (these can be key start-stop dates, organism, events, etc, See the criteria listed below)

Day 2: Build : As a group we will create our timeline by attaching our selected-researched items to the timeline at the appropriate timepoints.

 

• This timeline will be marked with a scale: 1 inch to to 1 million years:

 

• We will research and mark on the timeline "those major events that occured within the period chosen"; including these elements
• clearly mark where the subdivisions of eras, periods, and epochs occurs. Label them by name and their start-stop dates in millions of years
• mark the arrival, growth or extinction of new evolutionary "life forms"
• key developments in the evolution of life forms (such as flight, backbones, lungs, legs to walk on land, etc)
• key developments in the seas or oceans
• plants, new types of
• major geological events (major volcanic activity, continental movements)
• key extinctions: who perished- who survived
• ice ages: when and where
• glacial movements
• mountain building activities
• breakups or formations of supercontinents
• major climate shifts or trends

 

• Each student will pick an area of the time scale to concentrate on
• PreCambrian ( before 550 million) PowerPoint
• Paleozoic (550 - 250 million years ago) PowerPoint and PowerPoint B
• Mesozoic ( 250 - 60 million ) PowerPoint
• Cenozoic (60 - present) PowerPoint

You must research and label on your portion of the timeline, 20 key events that occured during the period that you have chosen. (sign-initial each piece you post on the timeline with your name clearly so I can tell who has credit for which parts of the timeline. If you do not post 15 parts, you do not get full credit)

 

You must also submit your list: your 20 key events in the period of your choice.

 

Grading: You get 5 points for every item you include in yout timeline. 20 items and you have a perfect 100 score. The teacher (Mr. Copel) holds the final right to say which items are appropriate or not and are worth the full credit.
