Energy waves in Year 9 Science
Start here
Focus on electromagnetic spectrum and ultrasound uses. Open support for “Describe How Waves Transfer Information by Microphones and Speakers”, then explain the idea in your own words.
Year 9 learners practise electromagnetic spectrum and ultrasound uses.
The activities include Describe How Waves Transfer Information by Microphones and Speakers, Describe Medical Uses of Ultrasound, Describe Non-Medical Uses of Ultrasound, and related practice. The checked support below includes video, worksheet, teaching, lesson. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
