Students learn how to use the Make-Make board, which interacts with conductive materials, to create music and games. The video also covers sound synthesis and introduces scientific tools like synthesizers for audio modulation. The practical lesson encourages students to explore and create their own projects, while also offering a fun, interactive way to understand electronic circuits and programming in a meaningful, real-world context.

Takeaways

• 😀 The lesson focuses on computational artifacts in Informatics for 7th-grade students as part of the Merdeka curriculum.
• 😀 Computational artifacts are objects created through computational thinking, such as programs, websites, photos, videos, and presentations.
• 😀 Tools for developing computational artifacts include integrated development environments (IDEs), video editing tools, 3D drawing software, and more.
• 😀 Make:Make is an electronic circuit board that can be used as an interactive input device, similar to a keyboard, and can connect to a computer.
• 😀 Make:Make allows for the creation of input devices using everyday conductive objects like fruits, wet leaves, and coins.
• 😀 The Make:Make board has 6 input holes for key functions (arrows, space bar, click) and additional inputs for other keyboard and mouse actions.
• 😀 The lesson demonstrates how to create a homemade musical instrument by connecting coins and a metal spoon to the Make:Make board and programming it with Scratch.
• 😀 Students are guided to connect the Make:Make board's inputs to different objects to trigger different sounds, such as bass drum, snare drum, etc.
• 😀 A metal spoon can be used as a drumstick and connected to the ground input, allowing students to interact with the circuit to create sound effects.
• 😀 The lesson introduces synthesizers and how they generate audio signals using methods like subtractive synthesis and frequency modulation.
• 😀 Sound is explained as a vibration transmitted through media like air or water, with humans able to hear frequencies between 20 Hz and 20k Hz.

Q & A

What is a computational artifact?

A computational artifact is an object created as a result of computational thinking. It can be in the form of a program code, application, website, image, audio, video, presentation, and other digital content.

What tools are used for the development of computational artifacts?

Tools used for developing computational artifacts include software integrated development environments (IDEs), video editing applications, office software, 3D drawing and printing tools, and other digital development platforms.

What is the Make:Make board and how does it work?

The Make:Make board is an electronic circuit board that can be connected to a computer and used to simulate a keyboard. It allows the creation of input devices from conductive materials, such as fruits or wet leaves, that interact with a computer.

Can everyday objects be used with the Make:Make board? Give examples.

Yes, everyday objects can be used with the Make:Make board if they are conductive. For example, bananas, tomatoes, and apples can be used to play a piano game, or wet leaves can be used to interact with a game.

What are the components of the Make:Make board?

The Make:Make board has several inputs: 6 non-ground holes and 6 ground holes on the front, and 12 additional inputs on the back for controlling keyboard buttons and mouse movements.

How do you create a musical instrument using the Make:Make board and Scratch?

To create a musical instrument, you need a computer, the Make:Make board, 6 crocodile clips, coins, and a metal spoon. You connect the clips to the coins as inputs for the drums (bass drum, snare drum, etc.) and use the metal spoon as a drumstick, connected to the ground.

How are the inputs for the drum set mapped in the Scratch project?

In the Scratch project, the inputs are mapped as follows: space for the bass drum, the up arrow for the snare drum, the right arrow for the hit head, the left arrow for the high head, and the down arrow for the crash cymbal.

What is sound, and how is it transmitted?

Sound is a vibration that travels as an acoustic wave through a medium like air, water, or solid substances. Humans can hear sounds within a frequency range of 20 Hz to 20 kHz.

What is a synthesizer and how does it generate audio?

A synthesizer is a musical instrument that generates audio through various synthesis methods, such as subtractive synthesis and frequency modulation synthesis. It uses components like oscillators, filters, and low-frequency oscillators to create sound.

What are the key characteristics of sound that make it recognizable?

The key characteristics of sound include its frequency (pitch), duration (length), intensity (loudness), and timbre (tone quality). These factors help distinguish different sounds.
