Trace a marked spot on a rope or a floating cork as a disturbance passes by. Separate the motion of the wave pattern from the back-and-forth or up-and-down motion of the material itself.

Use what you learned in the previous lesson to solve real-world problems.

Compare the direction a wave travels with the direction the medium moves locally. Classify rope waves as transverse and spring compression or sound waves as longitudinal using arrows, not memorized labels.

Distinguish a single pulse from a wave train by looking at how the source moves. Connect one flick or tap to one traveling disturbance, and repeated shaking to a continuing series of disturbances.

Use what you learned in the previous lesson to solve real-world problems.

Reason through sound as a mechanical wave even though you cannot see air moving. Follow compressions and rarefactions traveling from a speaker to an ear while individual air molecules only jiggle nearby.

Use ripples, ocean swells, and a bobbing object to describe water surface waves. Recognize that the visible pattern spreads across the surface while the water mostly moves locally rather than riding to shore with the wave.

Use what you learned in the previous lesson to solve real-world problems.

Treat an earthquake as a disturbance moving through rock and soil from a source. Recognize seismic waves by the medium they shake, the direction they travel, and whether the ground motion is more like a compression or a sideways shear.
