|---|---|---|---|
| 1 | What waves are | Unplugged: Shake a long rope or a slinky and make a wave travel down it; change how fast you shake and watch the wavelength change. | · |
| 2 | Pitch, loudness, and a check | · | |
| 3 | Wave speed and interference | · | |
| 4 | Behaviour check, then light | · | |
| 5 | Lenses and colour | Unplugged: Look at a distant light through a glass of water and watch it bend and flip. | · |
| 6 | Resonance and the boss | · |
