Sound Maker Code Modifications

This video provides guidance for teachers on how to support students in modifying their code for an investigation in Lesson 12. The investigation involves a sound maker and a sound receiver, with guidance on coding and modifying these components. Teachers are encouraged to guide students in exploring different coding solutions and understanding the effects of their code changes. The video also covers how to represent data from the sound receiver using various tools.

What is the primary role of the sound maker in the investigation setup?

• To control the light levels inside the box.

• To measure the temperature inside the box.

• To generate sound signals inside the box.

• To receive sound signals from outside the box.

Which code block can be used to introduce a delay in the sound maker's operation?

• A repeat block

• A pause block

• A loop block

• A sound block

How can students modify the sound maker to play different notes automatically?

• By using a different sound receiver

• By changing the volume settings

• By altering the frequency variable

• By copying and modifying the existing code

What is a simple way to change the frequency of notes in the sound maker code?

• Remove the frequency variable and set it directly

• Use a different sound receiver

• Adjust the volume level

• Change the USB port settings

How can students alter the volume of the sound maker during the investigation?

• By changing the USB port

• By adjusting the frequency variable

• By copying and pasting the volume code to different sections

• By using a different sound receiver

What is one way to display sound data on the microbit?

• Changing the sound frequency

• Plotting a bar graph on the LED

• Using a temperature sensor

• Using a different sound maker

What is the purpose of using a serial write function in the sound receiver code?

• To change the sound frequency

• To modify the sound maker

• To display a line graph on the computer

• To adjust the volume

Which tool can be used to log sound data for later analysis?

• A temperature sensor

• A light sensor

• A Data Logger

• A sound receiver

How can students ensure they are effectively modifying their code?

• By avoiding any changes to the code

• By using only the sound maker

• By exploring and making sense of the code themselves

• By following a strict set of instructions

What should teachers encourage students to do during the investigation?

• Explore and be creative with their code modifications

• Use only the sound receiver

• Avoid making any changes

• Follow a strict set of instructions
