The document summarizes a presentation about engaging middle school science students in mathematics and computational thinking through the use of predictive graphing. It discusses how predictive graphing can scaffold student understanding of SEP 5 (Using Mathematics and Computational Thinking). The presentation guides teachers to have students explore and graph frequency data about antibiotic resistance over generations, make predictions about how the data would change with a new antibiotic, and reflect on how this relates to developing explanations for changes in species survival.
