Starting an oldie but goodie thread. I am getting ready to start Threshold 5 on Monday and I am looking for the lessons that I cannot miss for the week? Does anyone have an idea that is original or outside the BHP curriculum to inspire a new idea? I would love to hear your thoughts and recommendations.

Jason Manning I do two activities that I adapted from their original online versions and that help students visualize the concepts of natural selection and DNA structure. For natural selection I get two types of candies that I place in equal numbers inside a bowl and pass it around for students to choose while we are covering the lesson. The tastier ones will be picked up first representing their reduced adaptability to survive in that environment. The least tasteful will survive the competition of predators. After two rounds of candies I look at the bowl, count the candies, and reflect upon the results.
For DNA my students build a DNA sequence pairing bases or nucleotides using twizzlers, gummies, and toothpicks. It also contributes to enhance the concept of scale and contextualization by zooming into the process. In my pedagogical sequence I do it after we read the article Crick, Watson, and Franklin, also including Rosalind Franklin story with this video.
