Science · Year 9 · Ready-made course
Four Year 9 Science lessons in the order textbooks teach the topic: what a wave is (through the Thousand-Hand Guanyin dance canon), how sound is made and what sets pitch and loudness, the speed of sound and v = fλ, and echoes, sonar and controlling sound in a room. Each lesson teaches the science first, with worked examples and a practical, then uses TEU interactives to investigate it.
Copy it into your account, change anything you like, and share it with your class using a class code or your LMS. Free for 30 days.
Across 4 lessons: 5 interactive activities, 4 knowledge checks, 4 practice tasks, 4 reflections and 6 data tables, using 4 different TEU interactives. Every lesson opens with a real question or scenario, states its learning intention, lists its learning outcomes and checks understanding with instant feedback.
In the Thousand-Hand Guanyin, a line of dancers makes one figure with a thousand moving arms. Something travels down the line - but none of the dancers do. What is it?
Students learn what a wave is, the two types of wave, and the words used to describe and measure any wave.

You can feel your throat buzz when you hum. How does that buzz reach someone across the room — and why can't astronauts hear each other in space without a radio?
Students learn how vibrations make sound, why sound needs a medium, and how the frequency and amplitude of a sound wave change what we hear.

Put your ear on a long metal railing while a friend taps the far end. You hear the tap twice — first through the metal, then through the air. Why?
Students learn why sound travels at different speeds through solids, liquids and gases, and how to calculate wave speed using v = fλ.

A ship sends a sound pulse down into the sea and hears it return 0.4 seconds later. How deep is the water?
Students learn how sound reflects from surfaces, how echoes can be used to measure distance, and how materials can be used to control sound in a room.

Each one can also be used on its own or in your own lessons.
Every copy of a course is yours. Reorder or remove lessons, rewrite text, swap questions and add your own interactives, images and video. Students join with a class code (no student accounts needed) or from Canvas, Moodle, Schoolbox or Brightspace, and you see each student's answers and progress as they work.
