Question.5126 - Module 7 discussion assignment: Building a class archive of stories from our planet's historyAssignment objective:Students will contribute a unique episode from our planet's history to a class archiveConnection to module objective:This assignment measures the module objective: Explore, research, and report on significant moments in Earth's history, place them in context, and synthesize their significanceDescription:Now that you've completed the "personalized exploration of Earth history" assignment, you know quite a bit about our planet's story. If you take a moment to reflect on the fact that all of your classmates have completed the same assignment, it quickly becomes apparent that, together, the amount of knowledge we possess as a class is truly impressive! In this assignment, each of you will contribute a unique entry to a class archive on Earth's history. We're going to build our own Earth history wiki!This assignment has two parts:Posting your contribution to the class archiveReading two other contributions you haven't seen before and letting the author know what you learned and thought was interestingSteps:Part 1âcontributing to the class archivePick an episode from our planet's history to contribute to the archive. You can pick one of the stories you used for the "personalized exploration of Earth history" assignment, or you can pick a new one. The only catch is that we don't want duplicate entries in our archive, so make sure and look through the entries your classmates have already contributed and ensure that the episode you're contributing hasn't already been added.Follow the same steps you used during the personalized exploration assignment:What video did you watch? (Title and hyper-link)What eon, era, and period did it take place in? If it took place over the course of multiple periods or eras, list all the eons and eras that apply. If it took place at a boundary between periods or eras, list bothWhat happened? Summarize in a paragraph what you learned about this episode in Earth's history. And feel free to supplement what you learn in the video with additional information you find online (Wikipedia is, as usual, a pretty solid first place to look)Why does it matter? Give me your take on the consequences or significance of the event you learned about, in a paragraphTell me what YOU found interesting about this story. What most stood out to you? Did anything surprise you?Post your responses to steps 1-5 above to this discussion thread. Your post will serve as an entry in our class wiki on stories from our planet's history!Format for each entryTo keep our archive organized and easy to use, we should use consistent formatting throughout. In writing your entry, use the following headers (in bold), followed by your text (not in bold):Title:Summary:Analysis:What I found fascinating:Part 2âexploring others' contributions to the archiveOnce everyone has added their contribution, we will have quite the archive of events from our planet's history.
