Teacher Notes

  • My students find this to be an extremely easy way to understand entropy. They go from knowing nothing about entropy to being proficient in less than half an hour. They start by identifying teacher desks (engagement), then they rank the desks from neatest to messiest. Lastly, they complete the PowerPoint lesson, referring back to the teacher desks. Sometimes they even present an entropy award to the winning teacher!
