Students draw a sketch and explain how they would shake the slinky. Observe Teacher asks students to find as many ways as they can to “shake the slinky” Students record observations by sketch and explanation. Explain Students will discover two distinct ways to shake the slinky (they do not know the names yet) Transverse Compression Explain Teacher gives a brief lesson on transverse and compression waves Sound is always transmitted as a compression wave. Light may be mentioned and that it is transmitted in a transverse wave form. Students should take notes or record their learning. It is encouraged that students take notes and teacher uses strategies to help students with vocabulary. Foldable, Concept Maps, Frayer Models, etc. Elaborate/Evaluate: Students act out “human waves” in small groups to demonstrate their knowledge of compression and transverse. Teacher evaluates student’s demonstrations for accuracy in depicting the waves. Making Waves – Frequency & Wavelength Resources Objective: Identify patterns in waves to interpret the relationship between frequency and wavelength Engage/Explore: Students will explore the changes in frequency and wavelength by shaking the slinky at different rates without removing it from the surface.
