Sensemaking is actively trying to figure out how the world works (science) or how to design solutions to problems (engineering). Students do science and engineering through the science and engineering practices. Engaging in these practices necessitates that students be part of a learning community to be able to share ideas, evaluate competing ideas, give and receive critique, and reach consensus. Whether this community of learners is made up of classmates or family members, students and adults build and refine science and engineering knowledge together.
Students wonder why the trait for resistance to rust disease has different frequencies in different coffee growing areas. They decide to create a model to help them explain this difference. They notice this trait has a lot more variation than they thought and decide to first model a simpler example. They learn about variation in populations of rock pocket mice and create a model that explains how the distribution of the trait changes over time and reflect on the model to identify the components of Natural Selection. Students use this model to return to the initial phenomenon to explain how that changes over time.
