1. Sound Monitor KS2: Design, write and debug programs which control physical systems.

2. ●I can create a sound monitor in Scratch

4. Sound monitor design ●Task: In pairs you have 5 minutes to create a design for your sound monitor. ●Your design should include: ○A sketch showing what you will use and what will happen when the volume changes. ○An algorithm describing how your sound monitor will work. ○Commands you think you might need in Scratch. Example sound monitor design

5. Programming your sound monitor ●Task: You have 20 minutes to write the program for your sound monitor. ●Remember to regularly test and debug your program. ○Identify what the program should do. ○Observe what the the program does do. ○Use your knowledge of the Scratch commands to work out where it went wrong. ○Fix it.

6. ●I can write a control program ●I can create a control system Today we have been learning about: Control, inputs and outputs

7. Control systems ●How many control systems can you think of in the world around you? ●What is the input? ●What is the output?
