Question.5124 - Module 11 Discussion: Rare Earth metals and modern technologyAssignment objective:In this assignment, students will do a deep dive into a single use of a rare earth metal, learning all they can about why that rare earth does its job so well, then sharing that information with the class Connection to module objectives:Discuss and analyze how the low-carbon energy transition is changing the resources we need, and how to reach a sustainable industrialized societyDescription:Now that you know about rare earth elements (I strongly suggest you complete the rare earth assignment before participating in this discussion), you're ready to do a deep dive into a specific application or use of a rare earth element in modern life. Choose one of the following applicationsâor another one that's not listed below if you likeâand get lost down a rare earth rabbit hole researching every detail you can find about that particular rare earth metal and its use in this specific application. More than anything, this assignment is about engaging beginner's mind, leading with curiosity, and honing your ability to find, understand, vet, and synthesize new information. Once you've become the expert on this specific topic, tell the rest of us what you learned in a discussion post here.Note: the deeper you go down the rabbit hole of one specific application, the more you may initially feel lost, like Alice in Wonderland. Don't panic though! Slow down and stay curious :) It's ok not to understand everything. Look up terms and words you don't know and keep the big picture in mind as you go. This is actually a great place to use AI if you wish toâif you encounter a topic you don't understand, ask an AI algorithm to explain it to you in a simple way (keeping in mind that they can sometimes provide misleading information). At the end of the day, the goal is to learn as much as you can, and to hone your ability to research and assess new information, not to understand everything perfectly :)Steps:Pick one of the rare earth uses below, or choose another that's not on the listMagnets: Neodymium, praseodymium, and samarium are used to make powerful permanent magnetsPhosphors: Yttrium, europium, and terbium are used as phosphors to make the touch screens in smart phonesOptical Fibers: Erbium is used in optical fibers (the things that carry the information back and forth whenever you do an internet search, stream a show or movie online, watch Youtube, etc.)Medical Imaging: Gadolinium is used in MRI (a medical imaging technique that allows us to see inside the human body)Steel Making: Cerium, lanthanum, neodymium, and praseodymium are used to remove impurities and produce special alloysMilitary Applications: Rare earth elements are used in radar systems, missiles, and other military technologiesDo a deep dive researching how this rare earth element does its job so well and why it is used instead of something cheaper or easier to obtainShare what you learned with the class. Make sure to include the followingThe name of the rare earth element(s) and the specific application/use you are researchingWhy this element is used instead of something easier to obtain (why it's the best choice for this application)One common product (e.g. smart phone, wind turbine, etc.) that incorporates this rare earth element and why you think it's importantChoose a post that explores a different application than the one you researched and learn all about this new use of rare earths. Then leave a reply letting them know what you learnedHow this assignment will be graded:This assignment is worth 40 ptsâ30 pts for your own research deep dive and 10 pts for learning from and replying to one of your fellow students. I will be looking for evidence of beginner's mind and evidence that you developed your research skills along the way.Reply
