  1. What can happen when light enters water?It refracts, or bends
  2. What happens to pitch as frequency rises?Pitch becomes higher
  3. Why are parallel circuit branches useful?Each branch can operate independently
  4. What is the electromagnetic spectrum?The full range of electromagnetic waves
  5. What does a switch control?Whether a circuit is open or closed
  6. What affects electromagnet strength?Current, coil turns, and core material
  7. Why can you hear an echo?Sound reflects from a surface
  8. Why does sound travel faster in solids?Close particles transfer vibrations quickly

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.
