● Discuss:

■ Which kind of memory do you think is faster, primary memory or secondary memory?

Possible Responses: Primary memory; Secondary memory.

Explanation: Primary memory is faster than secondary memory. Primary memory stores all the important data which is essential for the computer to run. We know that RAM holds data about all the active programs. ROM holds all the essential routines. Hence, primary memory is faster so that our computer can process smoothly.

■ “My data is stored in cloud storage.” Does that mean my data is floating around in a real cloud which brings rain?

Possible Responses: Yes; No; May be; Not sure.

Explanation: No. Data is not stored in a real physical cloud. Data is actually in some distant device. We can access this data using the internet.

● Conduct Fill Up on Page 10:

■ Say: Meteorites are approaching Avora. Let’s help Mel complete the sentences to get the magic wand and save Avora.

■ Read Q5 aloud, one by one.

■ Invite some students to share their responses.

■ Discuss and validate the answers with the whole class.

■ Instruct: Fill in the final answers in your books.

● Conduct Find the Truth section:

■ Say: Let’s practise more to revise what we have learned.

■ Read Q3, 4 and 5 aloud. Ask if it is true or false.

■ Invite some students to share their answers and others to validate their peers’ answers.

■ Instruct: Write the correct answers in your books.

Note

● If time permits, discuss Tick the Correct Answer - Q 1, 3 or, assign it in the homework.

● Conclude: Today, we learned about secondary memory and cloud storage.

● Ask the following probing questions:

■ Can we run the computer without primary memory?

Possible Answers: Yes; No; May be.

Explanation: No. Because Primary memory holds all the essential routines to run a computer. So, we cannot run the computer without primary memory.

● Assign the following homework:
