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

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.
