Waves & How They Move
CONCEPTUALDevelop a model of waves to describe patterns in terms of amplitude and wavelength, and understand that waves can cause objects to move
Mastery Evidence
- Describe a wave using the terms amplitude (height) and wavelength (distance between peaks)
- Demonstrate that larger amplitude means more energy (bigger waves move objects more)
- Model wave patterns using a slinky, rope, or water and describe what they observe
Assessment Prompt
“Can [child] use a slinky or rope to show how waves work, and explain that bigger waves have more energy and can move things more?”
