Why does the sunshield need multiple layers that don’t touch?
Lesson Snapshot
High school students, as scientists, investigate definitions of energy, conservation of energy and energy transfer, and electromagnetic radiation to answer the following driving question: Why does the sunshield need multiple layers that don’t touch? Students begin by taking stock of what parts of the anchoring phenomena they have explained, and which they still need to figure out. Next, students discuss how they could plan an investigation to answer their questions about conduction, radiation, and the James Webb Space Telescope (JWST) sunshield layers. Students plan the investigation and develop an initial model of the investigation system. Next, they conduct the investigation and use a simulation to investigate conduction at the particle scale. Finally, students revise their investigation system models based on data from the investigation and simulation.
