  1. Why does a shadow form?An object blocks light
  2. What happens to pitch as frequency rises?Pitch becomes higher
  3. What energy change occurs in a speaker?Electrical energy becomes sound
  4. What does a switch control?Whether a circuit is open or closed
  5. What affects electromagnet strength?Current, coil turns, and core material
  6. What can happen when light enters water?It refracts, or bends
  7. Why does sound travel faster in solids?Close particles transfer vibrations quickly
  8. Why are parallel circuit branches useful?Each branch can operate independently

Worked example

Use a model to track energy, forces, and waves through a system.

Common mistake

Assuming energy travels without a path or medium.

Helpful hint

Draw the source, path, interaction, and result.
