Sensemaking Checklist

What is Sensemaking?

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.

Lesson Snapshot

High school students as scientists investigate genetics, natural selection, and evolution to answer the following driving question: How does reduced genetic diversity impact survival and reproduction? Students analyze a graph to see that genetic diversity varies in different crops, but all populations do have some degree of genetic diversity. After analyzing genetic diversity across different species worldwide, students wonder why some populations have higher levels of genetic diversity than others and if this difference is significant. Next, students read two different articles about artificial selection and monocultures to look for patterns between the case studies. Students use this new information to discuss why scientists are concerned that both wild and cultivated arabica coffee populations have low genetic diversity. They then use what they have learned throughout this unit to explain how genetic diversity is maintained in populations and why genetic diversity is important, and they think about how they want to use this information to learn more and to help educate others. Then students return to their initial Driving Question Board to determine which questions they had can now be answered.
