Building Your Own Geologic Time Scale (Marie Bryan) by Marie Bryan https://padlet.com/mariehbryan/n2j6ftf5vn1wviee Scroll down to go BACK IN TIME! As you go along you will see the different time periods from the Geologic Time Scale. Throughout Unit 2, we are going to be adding onto this time scale to try and understand the unit question: Why do species change over time? For our first assignment: Use the information slides to attach the evolution events to the correct time period. Then, edit the posts to add traits to the new organisms. en-us 2025-03-02 19:45:33 UTC 2025-03-02 19:45:35 UTC hello@padlet.com First vascular plants mariehbryan https://padlet.com/mariehbryan/n2j6ftf5vn1wviee/wish/3348140880 Edit post to add traits of this organism from the picture and the slides:
