1. Draw a sprite using Paint editor in Scratch. Select different colours, brush tool to draw the picture. Use the stamp tool and the eyedropper tool.
2. Use the picture your draw and write a script. Save your project. Write a story to show what is happening in the project.
3. Write a script to show ___________ asana. [Vijaya, suggest what asana can be put]
To do this activity, divide the class into groups of five students each. Get Rangoli powder (coloured powder) and spread it on a sheet of a newspaper. Now take a wet sponge and dip it in the rangoli powder. One student has to draw a picture on the chart paper as per her group’s instruction. Each group draws different pictures such as sun, mountains, farm, etc. The teacher discusses the steps involved in doing the activity, compares it to giving instructions to the computer using scratch.
Find out how to make the sprite move in a circle.
Begin the class with playing a game. Blind fold one student and ask other students to give her directions to do an activity. For example, pick up a chalk from the table and write something on the blackboard. You can also draw a picture of an animal and ask the student to draw its tail. Note that other students are supposed to give directions to do the activity. Explain that doing the activity requires step by step instructions to their classmate. Just as we follow the instructions, the computer also needs instructions from us to do the activity. What we call step by step instructions; in computer language it is called programming.
Encourage the students to discuss what a particular object is called in their mother tongue. You will come across a variety of names for that object. Ask the students to imagine that they are visiting their friend’s grandparents, who do not understand your language. How will you communicate with them? The students might say that they will use non-verbal signs to convey what they are saying or take help from their friend. Inform the students, that just as you need to learn a few words of the language to communicate in the new region, you need to learn the language of the computer.
Introduce scratch as an interactive language of the computer. Explain that the sprite is like your blind folded friend, who needs proper instructions from you to do the activity. Demonstrate how you can make the sprite move 20 steps and change directions.
Ask the students if they want the sprite to make a sound as the activity is done. Import the sounds and add it from the stack of blocks. [Ensure that the speakers are connected]. You may also show them how to introduce a callout to make the sprite say or think something. Let the students give you the dialogue for the sprite.
Ask the students if they want another sprite. Demonstrate how to get the new sprite or create a sprite using the paint editor. You can ask the students to explore the options on their own and figure out how to change the background. Explain that sprites sounds and backgrounds are stored in sub-folders. The names of the sub-folders convey its contents, for their convenience. Revise the concept of folders and sub-folders. Ask questions such as “What would happen if the sub-folders were not used and all of them were placed in a single folder?” Encourage students to think and reason out the necessity of organising files into folders.
Explain that the instructions are placed in the appropriate blocks. For example, all the instructions about pen down are in the block called ‘pen’. Similarly, all the instructions for sound are in the folder called ‘sound’. Demonstrate the use of pen down and write a script to draw a square. Explain that the instructions given to the sprite is called script. This can be saved as project in the appropriate folder.
Summarise the lesson and ask the students to write their projects. You can ask them to write a story about the project they created.
You can end the class by asking students to do an exercise where students move their hands in the different directions --- forward, right, left, up, down, backward directions are given. Change the sequence of directions and make the game enjoyable. [In case of space constraints, ask them to move their neck instead of hands.]
