Reflection: Trust and Respect Radioactivity, Part Two - Section 2: Self-Directed Time: Electromagnetics Work


By this time in the investigation and, in a larger sense, this time of the year, students have developed a real sense of purpose and a wonderful sense of ownership. In the first of two short videos below, notice how, when the lights go out, not a single student changes focus - this "disruption" has no impact on student activity. Students know that some of the stations are light-sensitive and are expecting lighting conditions to change as necessary. It's also worth noting that students, not the teacher, adjust the lighting when necessary.


In this second video, one student advises another - not in his group - about the output of a specialized file being used to determine the energy output of the small turbine. I like the casual sharing and the sense of camaraderie that exists in this group and between groups. It's also a nice example of the turbine working - notice how quickly the blades are spinning.

Radioactivity, Part Two

Unit 4: Electromagnetics
Lesson 14 of 17

Objective: Students will examine radioactivity more closely and expand their understanding of the concept of "radiation."

Big Idea: The term "radiation" is complex and has many facets, including connections to the electromagnetic spectrum and nuclear decay.
