👩‍🏫 Teacher’s Guide

Objective
Students will explain that images, audio, and video are stored as data and identify basic ideas like pixels, samples, and frames.

Teaching Notes

• Use a zoomed-in picture to show pixels as tiny squares.
• Explain audio as sound samples over time.
• Explain video as many pictures (frames) shown quickly.
• Keep math minimal; focus on understanding and vocabulary.

🧒 Student Worksheet

Concept and Helping Material

Images, audio, and video are all stored as data. Images are made of pixels, audio is stored as sound samples, and video is made of many frames shown quickly to look like motion.

Computer Vocabulary and Definition

• — A tiny dot that makes up an image.
• — How clear an image is based on pixels.
• — A small piece of sound data.
• — One picture in a video.
• — The type of file, like JPG or MP4.

Computer QA

1. What is a pixel?
2. What does resolution mean?
3. What is a sample in audio?
4. What is a frame?
5. What is a format?
6. True or False: Images are made of pixels.
7. True or False: Video is one single picture.
8. What happens when resolution is higher?
9. What happens when resolution is low?
10. How is audio stored as data?
11. How is video stored as data?
12. What file format is common for photos?
13. What file format is common for videos?
14. Can audio be saved as a file?
15. Can video be shared online?
16. What is one example of an audio file?
17. True or False: A pixel is a kind of sound.
18. Why do videos look like they move?
19. What is one device that records video?
20. What is one way to make a file smaller?

Computer Prtactices

• Pixel art: Draw a small 10x10 grid picture using colored squares.
• Frame flipbook: Draw 6 frames of a ball moving to show motion.
• File format match: JPG → photo, MP3 → audio, MP4 → video.
• Resolution talk: Compare a clear image vs blurry image and explain why.

Reflection

• What is a pixel?
• How is video made from frames?
