This unit focuses on spiraling concepts of the atom, the electromagnetic spectrum, energy, material properties and nanotechnology. All lab activities are student-centered inquiry labs which are open-ended. The unit also includes two POGIL activities, which should be completed within student groups of 3-4 students.

Reviewer Comments:

This 2 – 3 week unit is targeted for an upper high school audience and incorporates topics in chemistry, physics and engineering as they relate to light production within LED devices. The lessons are structured to provide the opportunity for students to frequently revisit and extend their understanding of electromagnetic waves, material properties and energy throughout the course of the unit. This unit is very student-focused and set up for student success. For example, students are able to “requiz” to demonstrate their growth in a particular content area. Throughout all activities, there is a strong emphasis on student inquiry and discovery, and include the Process Oriented Guided Inquiry Learning, or POGIL, model. The teacher materials are detailed and clear. The lessons include clarifying images, detailed instructions, hints for implementation, assessments and answer keys for lab questions and quizzes. This well-organized unit provides materials to be challenging and engaging for high school students, as well as successfully implemented by educators in their own classrooms.
