OpenSciEd Physics + Earth & Space Unit 5: Electromagnetic Radiation Spanish Student Edition

OpenSciEd High School addresses all high school NGSS standards. This comprehensive science curriculum empowers students to question, design, investigate, and solve the world around them. 

• Phenomenon Based - Centered around exploring phenomena or solving problems
• Driven by Student Questions - Storyline based on students’ questions and ideas 
• Grounded in Evidence - Incremental building and revision of ideas based on evidence 
• Collaborative - class and teacher figure out ideas together
• Equitable - Builds a classroom culture that values ideas and learning of all

The OpenSciEd model uses a storyline approach, introducing phenomena that anchors storylines developing disciplinary core ideas, concepts, and science/engineering practices. Students are encouraged to dive deep into key points and solve problems through five activities. 

P.5 ¿Cómo usamos la radiación en nuestras vidas? ¿Es segura para los humanos?

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.
