Using the application Inspiration,I created a concept map designed to help students understand the variety of ways in which genetic changes can occur in a population over time. This was a timely, since I was teaching the topic in my current Tier 2 High School Biology Foundations long-term substitute-teaching assignment. While my trial subscription to Inspiration has expired, I can still show you the image of the concept map that I created. We did use several of the links and associated videos in Biology Foundations class.
