- The lesson introduces students to binary and its meaning through a starter activity.
- Three in-class activities:
- Activity 1: Identify binary values based on colors and complete a bitmap image.
- Activity 2: Understand memory requirements for storing digital images on computers.
- Activity 3: Compress a lossless image to lossy, identifying quality and size differences.
Digital Sound
- Starter activity: Retrieval practice with an exam-style question on last week's learning.
- Two in-class activities:
- Activity 1: Understand the difference between analogue and digital devices, illustrating the ADC process.
- Activity 2: Change sample rates to observe differences in quality and sound.
Measuring and Storing Data
- Starter activity: Retrieval practice with an exam-style question on last week's learning.
- One in-class activity:
- Understand different units of digital data and their sizes, converting file sizes between units (e.g., MB to GB).
Resources and Assessment
