Task 3: Option 2

Learning tasks

  1. Explore audio, video, text and image files to examine standard encoding formats such as MP3 for audio files, ASCII or Unicode for text, JPEG for images and MOV, AVI and WMV for video.
  2. Make a chart of the different formats. Share ideas and decide on common file types and ones with which students are familiar. Explain that all these files use the binary system of encoding.
  3. Provide resources to explore the binary number system with the aim of finding interesting information about the binary system and to raise questions for inquiry. As students explore the fundamentals of the binary system, challenge them to find out and share three things they have learned and any questions that arise.
  4. Write a list about what the class knows about binary. Then view an informative video about binary numbers. Update the list with revisions and new ideas.
