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 definitions of energy and electromagnetic radiation to answer the following driving question: How does the JWST’s sunshield help maintain the operating temperature of the infrared instruments? Students are introduced to a phenomenon: the JWST system has a hot side and a cold side with instruments that need to stay at very cold operating temperatures. Separating the two sides is a sunshield. Students evaluate information about the JWST’s open design and a different space telescope with a closed design (Hubble). Students record observations and questions and develop initial models. Students next consider related phenomena. Students plan and carry out investigations that help them identify patterns related to light and energy transfer. Next, students use two simulations to investigate energy transfer and temperature at the atomic scale. Students also evaluate information in an article about electromagnetic radiation. Students revise their initial models using data, simulation observations, and information from the article. Finally, students create a Driving Question Board (DQB) to capture their questions about the phenomenon and discuss what they will investigate in the next lesson.
