Anchor Phenomenon Ideas: Share this looking through water phenomenon with your students and/or let them play with slinkies. Then, use the questions they come up with about waves to make connections throughout your unit.
Make it Relevant: Focus on sound waves and music as you engage students in this unit. This TED-Ed talk answers the question: Can loud music damage your hearing?
Tips and Tricks: Encourage students to take the time to really explore waves within the two PhET simulations: Waves and Waves on a String. Their boxes for question four should be completely filled with observations, wonderings and questions.
Continue to support play as learning as kids work with the flashlights, beakers, water, mirrors and other materials you have available for question five. Challenge students to show examples of wave transmission, reflection and absorption in the lab and record their observations in detail. Again, fill the box entirely!
To the right is a student sample of question five. When reviewing the drawings, I asked how they know the light is reflected off the mirror. They explained that they could see the light bounce off the mirror and onto their hand!
