Computer science Lesson Plan
Class: 7th - Lesson:11 Text to Speech & Video sensing

Purpose:Understand how to use Text to Speech to create talking sprites and How to apply Video Sensing to detect motion from a webcam and trigger events.

No. of Classes

One or two classes (Teacher's decision).

Materials Required

Scratch 3.0.

Curriculum Content
  • 2.10) Text to Speech
  • 2.11) Video Sensing
    •

    Prior knowledge

    Familiarity with basic Scratch concepts (Events, Loops, Variables, Clones, Custom Blocks).

    Exercises

    Exercise:1


  • Create a scratch code in which you have to use text speech. For example create a scratch in which you have to explain the benifits of walking, running etc..

    • Exercise:2


  • Create a code in which you should use video sensing. For example when a video on sprite will change to another backdrop or change to next costumes.

    • Solutions


  • Link to copy solution program for exercise-1.
  • Link to copy solution program for exercise-2.

    • Teacher's Instruction
    1. Before starting, ensure students are familiar with basic Scratch blocks like Events, Motion, Looks, Operators, and how to create simple programs.
    2. Teach students how to add extensions (Text to speech, Video sensing) in Scratch.
