    Study Notes

    Lesson Topic Structure

    Digital Images

    • 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

    • Self-checker tool: Quizzes in Microsoft Forms for each lesson.
    • Knowledge organisers provided for each topic: Bitmap, Vector, Compression, Analogue and Digital Data, and Measuring and Storing Data.
    • Revision workbook provided with teacher and student versions.
