Standard 4.3.1
Develop and use a model to describe the regular patterns of waves. Emphasize patterns in terms of amplitude and wavelength. Examples of models could include diagrams, analogies, and physical models such as water or rope. (PS4.A)
Standard 4.3.2
Develop and use a model to describe how visible light waves reflected from objects enter the eye causing objects to be seen. Emphasize the reflection and movement of light. The structure and function of organs and organ systems and the relationship between color and wavelength will be taught in Grades 6 through 8. (PS4.B)
Standard 4.3.3
Design a solution to an information transfer problem using wave patterns. Define the problem, identify criteria and constraints, develop possible solutions using models, analyze data from testing solutions, and propose modifications for optimizing a solution. Examples could include using light to transmit a message in Morse code or using lenses and mirrors to see objects that are far away. (PS4.C, ETS1.A, ETS1.B, ETS1.C)

Materials: Plastic Slinkys, 10-foot nylon ropes, masking tape. [1]
Transverse Waves: Tie one end of the rope to a doorknob. Have a student shake the other end up and down. Place tape on one spot of the rope. Students observe that the tape only moves up and down (amplitude), while the wave moves forward. [1, 2, 3, 4, 5]
Longitudinal Waves: Stretch the Slinky on the floor. Gather a few coils and release. Students observe compression and rarefaction, mapping how "amplitude" in this analogy equals the density of the compressed coils. [1, 2, 3]
