OpenSciEd is a nonprofit organization that brings together educators, philanthropic organizations, curriculum developers, and professional development providers to improve science education through the development and implementation of high-quality, freely available science instructional materials. The goal of OpenSciEd is to ensure that all educators, from elementary to high school, have access to a free, coherent, rigorous, research-based set of instructional materials that will support all students in meeting the vision for science literacy described in A Framework for K-12 Science Education and the Next Generation Science Standards.

How do we use radiation in our lives, and is it safe for humans? This unit begins with a news article about the unconventional use of microwave ovens to store electronics. Students are motivated to test the behavior of a Bluetooth speaker playing music from a device inside the oven when it is not running. They also test what happens when it runs and heats up food. This phenomenon sets the stage for exploring wave behavior, the interactions of matter with electromagnetic radiation, and how we can use these interactions in different technologies to digitize, store and transfer information. ​​Throughout the unit, students use simulations to model field interactions and energy transfer through electromagnetic radiation. They conduct investigations using the microwave oven to explore how different materials interact with microwave radiation, and how the structure of this device affects energy transfer. Students explain how the frequency and amplitude of electromagnetic radiation affects its interactions with matter and evaluate the wave and photon models of electromagnetic radiation. Students obtain and communicate information about the uses of electromagnetic radiation, its safety, and methods of protection. They apply these ideas in a culminating task to evaluate whether 5G technology is safe.
