Electromagnetic Radiation and Forces of Nature
1 Guided Practice
- I will begin my lesson my showing my students this video over electromagnetic radiation: https://www.youtube.com/watch?v=gtgBHsSzCPE&feature=em-share_video_user
- After showing the video, I will break my students into groups and let them work in groups to determine the difference between waves and forces of nature.
- While students are in their groups, I will walk around the classroom and monitor student work.
- When students are finished with their group work we will come together for a class discussion over what the students have learned.
- Students will watch the video of Bill Nye: The Science Guy.
- The class will break into groups of five, four, and four.
- In group one, I will provide the students with a slinky they will be able to work with and learn about the different types of waves that are on the electromagnetic spectrum. They will give me examples of how forces of nature (air, water, and solids) affect waves.
- In group two, I will provide students with a glass of water and a spoon so they can learn about refraction, reflection, diffraction, and absorption.
- In group three, students will make their own form of type of series and parallel circuit and discuss how they transfer energy. Students will explain that electric currents and magnets can exert force on each other.
- Students will end class with a group discussion playing Kahoot that will allow me to see what the students have learned about forces of nature and electromagnetic waves.
