COMPUTER SCIENCE Term I-II

8

Foreword Uolo’s Tekie program offers a coding-focused curriculum for grades 1 to 8, preparing students for the technology-driven world. We present a carefully crafted Teacher Manual to assist teachers in delivering effective and engaging lessons to students. Rather than prescribing teaching methods, the manual provides examples and demonstrates how and why teachers can apply these examples in their classes.

Within the academic year, the Tekie program prescribes the following types of chapters and sessions: Theory: these periods are dedicated to the Computer Science Theory chapters. These topics are mostly delivered in the classroom.

Tools: these periods are dedicated to the Computer Tools chapters. These topics involve almost equal numbers of classroom and computer labs sessions.

Coding: these periods are dedicated to the Coding chapters. These topics have more computer lab sessions.

Each chapter in this manual is structured to provide a comprehensive lesson plan. The chapters are divided into multiple sessions, each following the Warm up, Engage, Build, and Sum up (WEBS) strategy.

The Warm up phase sets the stage for learning by connecting to prior knowledge and building curiosity.

The Engage phase captures the students’ attention and motivates them to participate actively. In the Build phase, questions from various sections are discussed to build the understanding of the students.

Finally, the Sum up phase reinforces learning through easy-to-recall activities and questions. Time duration for each section has been suggested based on the requirements of the students. Additionally, an answer key for every chapter is provided to assist teachers in assessing their students’ understanding and guiding their learning effectively.

We hope that this teacher manual will empower teachers to use the curriculum effectively, support the learning of all students thoroughly, create learning opportunities and design interactive learning environments that cater to the students’ needs and interests.

Operating System Story Time

Story in a Nutshell…

It is another bright day in Avora. Mel, Conji, and Eva decide to utilise their time off to learn more about their city’s interesting history in the Museum. They find the legendary Keystone that Eva’s mother had used to drive Lord Ero away. Curious to know more about it, they read about the artefact when they find that it increases the power of a wizard’s spell by giving specific commands, like how an operating software executes commands for a computer. After learning about operating softwares from Mel, Conji and Eva begin to explore the Museum when suddenly, Ms Idea shows up, behaving strangely and claiming to be Eva’s mother. There is also a weird magical storm that is causing chaos in the city, made

by Dark Magic. She tries to attack the group but is defeated by her spell. The Elder Wizard shows up and reveals that the keystones can restore Ms Idea’s memories, as she was indeed Eva’s long-lost mother.

The trio go on a quest to find the remaining Keystones while also learning about Google Sheets, app development, algorithmic thinking, and Canva. Eva goes off to fight Lord Ero alone but is captured. Mel and Conji show up to save her and use the power of the Keystones to defeat Lord Ero. They arrive back in their city, where they are able to bring back Ms Idea’s memories and also drive away the storm that Lord Ero had created. Eva is finally reunited with her mother, and all is well again!

Mel, Conji, and Eva decide to explore the history of Avora in the Museum.

Mel expresses how interesting it is to learn about the city’s vast history of magic and technology.

Conji agrees with Mel and points out an artefact that seems to belong to Eva’s mother, encouraging Eva to take a look.

Eva recognises it as the legendary keystone, which she used to defeat Lord Ero, but she vanished right after its use.

The memories of her family and the events surrounding the keystone bring tears to Eva’s eyes, and she starts sobbing in a corner.

Conji reassures her that she does have a family and that they are there to support her.

They hear a loud thunder, which puzzles Conji, as the weather has been sunny when they enter the museum.

Conji says that the keystone is a powerful magical tool that can control many spells and make them more powerful.

Mel says that this sounds a lot like how an Operating System controls the execution of all programs on a computer.

●

Computational thinking: Computational thinking is the process of conceptualising problems in such a way that the resulting solutions can be viewed as computational operations and algorithms.

Decomposition: Decomposition is the process of dividing a difficult activity or problem into smaller, easy-to-solve components or sub-problems.

Pattern recognition: Pattern recognition is a data analysis method that uses machine learning algorithms to automatically recognise patterns and regularities in data.

Abstraction: Abstraction means focusing on the most important parts and ignoring the details that don’t matter.

Algorithmic design: Algorithmic design is a critical problem-solving skill. It strengthens the ability to create a process for finding a solution as opposed to focusing on the answer itself.

Read aloud the questions provided in the Do It Yourself 3B and encourage students to solve them.

Instruct them to write the answers in their book.

Correct Responses: To plan and organise a school event like a science fair, I would use computational thinking elements as follows: Decomposition: Break down the event into smaller tasks, like setting up exhibits, scheduling presentations, and managing attendees.

Pattern matching: Identify the recurring elements, like registration procedures or equipment setup to streamline processes.

Abstraction: Focus on key details like coordinating with participants and judges, abstracting away less critical aspects.

Algorithm design: Develop step-by-step procedures for tasks like exhibit registration, judge assignment, and event scheduling to ensure smooth operation.

Build

●

7 mins

Conduct a group discussion in the class among the students based on the topic provided in the Discuss section as mentioned on page 37.

Possible Responses: Algorithmic thinking is crucial because it enhances a student’s ability to think critically. It broadens their minds to the additional capabilities of a particular solution and helps them see a problem more holistically. For example, imagine you have a list of numbers that you want to sort in ascending order. A small algorithm for this would be as given below: a. Start with the first element in the list. b. Compare the current element with the next element. c. If the current element is greater than the next element, swap them. d. Move to the next element and repeat the comparison and swap if necessary. e. Continue this process until no swaps are needed, indicating the list is sorted.

●

Ask the students to answer to the question “Imagine you have a box of colourful crayons. You want to arrange them in a pattern, but you can use only two colours at a time. How would you create a beautiful pattern using your crayons?” asked in the Think and Tell section on page 4.

Chapter 2 • Computational and Algorithmic Thinking

13

Possible Responses: To create a beautiful pattern, we would group the crayons into pairs of two colours and arrange them in a repeating sequence, such as alternating between red and blue, yellow and green, or any other combination that appeals to us. ●

Conduct a group discussion in the class among the students based on the topic provided in the Discuss section as mentioned on page 38.

Possible Responses: Computational thinking, like using algorithms, is like following a recipe to solve everyday problems step by step, whether you are completing your homework, planning a party, or even sorting your clothes. By breaking big tasks into smaller, manageable parts (decomposition), and finding patterns (pattern recognition) or creating steps to make things easier (algorithms), focusing on the tasks that require priority (abstraction), you can tackle almost any challenge more efficiently.

●

Ask the students to answer to the question “Imagine you are a chef, and your job is to bake a perfect chocolate cake. Just like following a recipe, you have to follow a set of step-by-step instructions.

What do you think would happen if you mixed up the steps or left some out? How important is it to follow the ‘algorithm’ (recipe) correctly when baking a cake?” asked in the Think and Tell section on page 39.

Possible Responses: If the steps are mixed, then the following may happen: a. Ingredients not mixing properly: If you add ingredients in the wrong order, they may not mix as intended. For example, mixing sugar into whipped eggs before adding the flour can affect the cake’s structure and texture. b. Inconsistent texture: Beating eggs and sugar before adding other ingredients incorporates air and gives the cake its lightness. Doing this out of order could result in a dense or uneven texture. c. Failed chemical reactions: Baking powder or baking soda, which causes the cake to rise, must be added at specific times for it to react properly. Mixing up the steps could lead to a cake that does not rise.

Sum Up

●

●

Conclude the session by summarising that an algorithm is a step-by-step guide to solve a problem or complete a task, and it is important because by using algorithms, we can clearly outline what we need to start with, the steps we need to take, and what we aim to achieve, making tasks simpler and more straightforward. Again, flowcharts help us see how to solve problems visually, using shapes to represent steps, like adding two numbers together and then checking if the result is even or odd with a decision step.

Formulas and Functions in Google Sheets Story Time

Story in a Nutshell…

Mel, Conji, and Eva are in the school playground when they hear an announcement from Elder Wizard.

On reaching the Council Room, the Elders inform them about Lord Ero’s attack on robot-kinds’ special ability to learn. The trio visits the control room to take the backup. But they were too late, as Mel had lost her ability to use the rising charm, and Elder Robot too is feeling weak. Elder Robot senses an attack on the main system. Lord Ero has created a dark spell to stop robots from using magic. While the trio is working hard to find the solution, Avora is under attack and loses its power backup. Elder Robot risks his life to find the solution. The trio works hard to create a magic-chain to be able to re-distribute the magical ability to all robots. To everyone’s surprise, Mel’s battery runs out, and she collapses. Elder Wizard comes to her rescue. Using computational thinking, they are able to restore harmony in Avora.

Elder Robot’s server is still affected, and while he and Eva attempt to reprogramme things, Mel and Conji help him re-organise his office.

Mel takes a nap in her room to recharge her system.

Conji and Eva go to visit her. They ask her if she is feeling better now.

Mel tells them that her circuits are still weak. She does not know what the virus has done to her.

Eva mentions Elder Robot can help, and Elder Wizard has an important message.

They meet Elder Wizard, who praises them for fighting off Lord Ero’s attack but explains it weakened Mel and Elder Robot.

Elder Wizard magically restores the Elder Robot’s circuits, but he’s still tired.

Elder Robot scans Mel, finding her internal circuits messed up by the dark virus, likely due to being built by Lord Ero. Mel asks to have her circuits destroyed, fearing she’s a danger.

Elder Robot reprograms Mel, securing her system from future attacks.

Eva suggests using the same method to secure the Magic-chain from dark magic.

Elder Robot agrees and plans to teach the children using Google Sheets. Mel explains what Google Sheets is.

Data Visualisation Using Google Sheets Story Time

Story in a Nutshell…

It is another bright day in Avora. Mel, Conji and Eva decide to utilise their time off to learn more about their city’s interesting history in the Museum. They find the legendary Keystone that Eva’s mother had used to drive Lord Ero away. Curious to know more about it, they read about the artefact when they find that it increases the power of a wizard’s spell by giving specific commands, like how an operating software executes commands for a computer. After learning about operating softwares from Mel, Conji and Eva begin to explore the Museum when suddenly, Ms Idea shows up, behaving strangely and claiming to be Eva’s mother. There is also a weird Magical storm that is causing chaos in the city, made

by Dark Magic. She tries to attack the group but is defeated by her own spell. The Elder Wizard shows up, and reveals that the keystones can restore Ms Idea’s memories as she was indeed Eva’s long lost mother. The trio go on a quest to find the remaining Keystones while also learning about Google Sheets, app development, algorithmic thinking and Canva. Eva goes off to fight Lord Ero alone but is captured.

Mel and Conji show up to save her and use the power of the Keystones to defeat Lord Ero. They arrive back to their city where they are able to bring back Ms Idea’s memories and also drive away the storm that Lord Ero had created. Eva is finally reunited with her mother and all is well again!

Story in This Chapter… ●

Mel and Conji meet with the Elders to discuss their next move against Lord Ero.

●

Elder Robot expresses disbelief at Eva’s decision to face Lord Ero alone.

●

Elder Wizard suggests that they must go to Lord Ero’s Dungeon to help Eva and find the last keystone.

●

Conji emphasises the importance of learning how to use the keystone in their final confrontation with Lord Ero.

●

Elder Wizard explains that Ms. Idea, who can control the keystones, is currently in a magical sleep.

●

Mel questions if Eva is under Lord Ero’s spell, showing concern for her well-being.

●

●

●

The Elders decide that Mel and Conji must trick Lord Ero into coming to them, while they work on bringing Eva back.

Elder Wizard equips the kids with powerful spells and instructs them to use the power of the keystones to enhance their magic.

Despite encountering unexpected obstacles with the awakening robots, Mel and Conji plan to document the spells on Google Sheets to remember them efficiently.

Your teacher wants to decide on the best day of the trip based on the weather forecasts for the upcoming week. However, the weather data is presented in a confusing table format, making it difficult to understand at a glance.

To improve the decision-making, you could create a simple bar chart showing the forecasted temperatures for each day of the week. Each bar represents a day, and its height corresponds to the forecasted temperature. You could colour-code the bars to indicate different weather conditions like sunny, cloudy, or rainy.

Benefits of using a bar chart ●

Computer Networks Story Time

Story in a Nutshell…

It is another bright day in Avora. Mel, Conji, and Eva decide to utilise their time off to learn more about their city’s interesting history in the Museum. They find the legendary Keystone that Eva’s mother had used to drive Lord Ero away. Curious to know more about it, they read about the artefact when they find that it increases the power of a wizard’s spell by giving specific commands, like how an operating software executes commands for a computer. After learning about operating softwares from Mel, Conji and Eva begin to explore the Museum when suddenly, Ms Idea shows up, behaving strangely and claiming to be Eva’s mother. There is also a weird magical storm that is causing chaos in the city, made by Dark Magic. She tries to attack the group, but is defeated by her own spell. Elder Wizard shows up, and reveals that the keystones can restore Ms Idea’s memories as she was indeed Eva’s long-lost mother. The trio go on a quest to find the remaining Keystones while also learning about Google Sheets, app development, algorithmic thinking, and Canva. Eva goes off to fight Lord Ero alone but is captured.

Mel and Conji show up to save her and use the power of the Keystones to defeat Lord Ero. They arrive back to their city, where they are able to bring back Ms Idea’s memories and also drive away the storm that Lord Ero had created. Eva is finally reunited with her mother, and all is well again!

Story in This Chapter… ●

●

Ms Idea is struck by her own spell and falls unconscious, leading to the questions about her being Eva’s mother.

The group learns from the Elder Wizard that Ms Idea is indeed her mother, but she lost her memories due to using a powerful artefact called the Keystone.

●

The Keystone is needed to defeat the Dark Magic but has the side effect of erasing memories.

●

There are four Keystones in total, and all are required to restore Ms Idea’s memories.

●

Elder Wizard admits to keeping this truth from Eva to protect her from the harsh reality.

●

●

The Keystones work by forming a magical network, enhancing the power of spells, similar to how computer networks operate.

Mel explains the concept of computer networks to Conji and Eva.

Spring has sprung! Mel, Conji, and Eva are enjoying a beautiful morning in Avora, when they think of their fairy friend, Joy. They go to the Magical Garden to visit her, where they realise that Joy has been captured with a spell by the evil Lord Ero! The Garden, is stuck in the winter and the trio must now find Joy who has left a strange riddle behind. The Elders tell our heroes that Dark Magic grows stronger in the cold, and they need to find a way to break it, otherwise, the entire city will get stuck in winters. They tell the trio to find an ancient spell that will restore the fairy’s magic, but Elder Wizard realises that there is a traitor in their midst. The trio promises to find the traitor and save Avora. They board a spaceship that will take them to the Space Centre, the place where the ancient spell is hidden. It turns out that they were too late. They see Avora’s Control Room being destroyed by Dark Magic. It is then that they decide to use the ancient spell to travel back in time and save Avora before Lord Ero’s attack. They find the spell, go back to the past where Mel and Conji realise it was Eva who had been betraying them all along! Joy and the Elders join them in a final showdown against Lord Ero and trap him in a powerful fairy crystal.

Eva is freed as spring comes back to Avora and all is well again!

After using the computational and algorithmic thinking to open the door to the spaceship, the trio of Mel, Conji, and Eva went to the Space Centre to find the ancient spell.

The trio desperately wants to stop Lord Ero’s destructive plans.

Conji suggests using a banned technique, time travel, to prevent Lord Ero’s actions. Despite the danger, they agree it’s their only option.

Mel suggests using the power of the spell to develop an app to track the digital presence of the Dark Magic. Eva then asks what an app is and how it can be developed.

Though they are unfamiliar with technology, they are willing to learn and combine magic and technology to achieve their goal.

Web Application Using a Database Story Time

Story in a Nutshell…

Spring has sprung! Mel, Conji, and Eva are enjoying a beautiful morning in Avora, when they think of their fairy friend, Joy. They go to the Magical Garden to visit her, where they realise that Joy has been captured with a spell by the evil Lord Ero! The Garden is stuck in winter and the trio must now find Joy who has left a strange riddle behind. The Elders tell our heroes that the Dark Magic grows stronger in the cold and they need to find a way to break it, otherwise the entire city will get stuck in winter. They tell the trio to find an ancient spell that will restore the fairy’s magic, but Elder Wizard realises that there is a traitor in their midst. The trio promises to find the traitor and save Avora. They board a spaceship that will take them to the Space Centre, the place where the ancient spell is hidden. It turns out that they were too late. They see Avora’s Control Room being destroyed by Dark Magic. It is then that they decide to use the ancient spell to travel back in time and save Avora before Lord Ero’s attack. They find the spell and go back to the past, where Mel and Conji realise it was Eva who had been betraying them all along! Joy and the Elders join them in a final showdown against Lord Ero and trap him in a powerful fairy crystal. Eva is freed as spring comes back to Avora, and all is well again!

Story in This Chapter… ● ●

●

Eva betrays her friends by siding with Lord Ero which shocks Mel because Avora is also Eva’s home.

Conji realises Eva is under a spell used by Lord Ero, similar to how Joy was forced to give up a password before.

Conji figures out Eva is under the spell because of her suspicious actions, such as knowing secrets she shouldn’t and coming back from the elders too quickly.

●

Lord Ero attempts to destroy Mel and Conji with a spell, but Joy saves them by blocking the attack.

●

Joy is freed from the spell by Elder Robot, who finds her through a riddle leading to the Fairy Cave.

●

The group plans to defeat Lord Ero using an ancient spell and to trap him in Fairy Stones.

●

●

To ensure Lord Ero cannot escape, Mel suggests linking the trap to a database and to the Fairy’s Web app, which can track him.

The team splits tasks: Joy prepares the ancient spell, while Mel explains the technical plan to Conji.

AI—Natural Language Processing Story Time

Story in a Nutshell…

Spring has sprung! Mel, Conji, and Eva are enjoying a beautiful morning in Avora, when they think of their fairy friend, Joy. They go to the Magical Garden to visit her, where they realise that Joy has been captured with a spell by the evil Lord Ero! The Garden is stuck in winter and the trio must now find Joy who has left a strange riddle behind. The Elders tell our heroes that the Dark Magic grows stronger in the cold and they need to find a way to break it, otherwise the entire city will get stuck in winter. They tell the trio to find an ancient spell that will restore the fairy’s magic, but Elder Wizard realises that there is a traitor in their midst. The trio promises to find the traitor and save Avora. They board a spaceship that will take them to the Space Centre, the place where the ancient spell is hidden. It turns out that they were too late. They see Avora’s Control Room being destroyed by Dark Magic. It is then that they decide to use the ancient spell to travel back in time and save Avora before Lord Ero’s attack. They find the spell and go back to the past, where Mel and Conji realise it was Eva who had been betraying them all along!

Joy and the Elders join them in a final showdown against Lord Ero and trap him in a powerful fairy crystal.

Eva is freed as spring comes back to Avora, and all is well again!

GUI stands for Graphical User Interface. It employs graphical elements such as icons, buttons, windows, and menus to enable users to interact with computers and software applications. It makes our work easier as it provides an intuitive and visual based means of navigating, controlling, and accessing digital content, making computing more user-friendly.

4. A single-user operating system is designed for personal use and allows only one person to use the computer at a time, whereas a multiuser operating system is a computer system that allows multiple users that are on different computers to access shared resources and data at the same time.

5. Features of a real-time operating system:

i. A real-time operating system is engineered to provide rapid and consistent responses to processes or tasks. ii. RTOS ensures that a task starts and finishes at a specific time, which is essential for applications such as data acquisition where data must be sampled at fixed intervals without deviation. iii. A RTOS guarantees that tasks are executed with precise and consistent timing. This reliability ensures that critical operations such as controlling machinery or processing data occur predictably and within specified time constraints.

1. A column chart is a practical and effective choice for visualising monthly expenditure data over a year that provides a clear representation of trends in expenditures over time.

Some of the reasons for using column charts are: ● Comparison: Column charts allow for easy comparison between different months. Each column

represents a month, making it simple to see how expenditures vary from one month to another.

● Sequential data: The sequence of months is well represented in a column chart. This makes it easy for

the viewers to follow the progression of expenditures throughout the year.

● Clear representation: Column charts provide a clear visual representation of data. The height of each

column directly corresponds to the expenditure amount making it straightforward for viewers to interpret the data accurately.

2. You can customise the chart by adjusting various options, such as chart styles, chart and axis titles, data series, legends, gridlines, etc., available under the Customise tab in the Chart editor pane. As you make changes in the Chart editor, you can preview your chart in real-time to see how it will look.

This variable cannot be used outside the block it has been initialised to. On the other hand, a variable declared inside a class but outside the body of methods is called an instance variable. Instance variables cannot be accessed directly. The new operator is used to create an instance of the class, which is used to access the instance variables.

2. Arithmetic operators in Java are used along with the integer or float values and variables to perform mathematical operations on them.

Subtracts one value from public class another.

SubtractTwoNumbers { public static void main(String[] args) { int num1 = 5; int num2 = 6; int difference = num1 - num2; System.out.println(“The difference between “ +

num1 + “ and “ + num2 + “ is: “ + difference); } }

3. The purpose of variables in Java is: ● Variables are the containers that hold data values. ● Variables can be updated or modified during the execution of a program. ● Variables reserve a specific memory location for the stored data. ● A variable can be used multiple times in a program.

Answer the Following.

1. T 2. T 3. T 4. T 5. F 1. Artificial intelligence is the process of giving a computer the capability to think, learn, and make decisions, just like humans do.

Two applications of AI are: Chatbots: AI-powered chatbots in education can assist both students and teachers with various tasks, such as preparing study material, doing school work, answering questions, etc. They also help in the customer service industry.

Recommendation Systems: AI can suggest books, movies, or music based on users’ tastes. It learns from their preferences.

2. Narrow AI, also known as Weak AI, is good at doing one specific task, but it does not understand or think as humans do. Voice assistants such as Alexa, Apple Siri, and Google Assistant are all examples of narrow artificial intelligence.

On the other hand, Super AI (Super Artificial Intelligence) is like a super-smart computer program that can think, learn, and solve complicated problems all on its own.

3. General AI, also known as Artificial General Intelligence or AGI, is like a super-smart computer that can learn, understand, and do many different tasks just like human beings. A self-driving car is an example of a general AI. 4. MIT App Inventor is an online platform for creating apps for mobile phones and tablets.

5.

Super AI is still an imaginary concept of Artificial Intelligence. It is still a hard effort to develop such systems in the real world.

1. The different domains of AI are: Computer Vision Machine Learning Natural Language Processing 2. Uses of AI in everyday life: Recommendation Systems: AI can suggest books, movies, or music based on users’ tastes.

Voice Assistants: AI is used in voice assistants like Siri or Alexa to recognise and carry out spoken orders.

Image Recognition: AI can identify objects in pictures.

Language Translation: AI can translate languages, making it simpler to communicate with individuals throughout the world.

Medical Diagnosis: AI helps doctors analyse medical images like X-rays and MRIs to detect diseases.

Autonomous Vehicles: Self-driving cars use AI to navigate and make decisions, like avoiding obstacles.

3. Super AI (Super Artificial Intelligence) is like a super-smart computer program that can think, learn, and solve complicated problems all on its own. It is far more intelligent than typical computer programs and is even capable of understanding and performing tasks that only humans can do, including making decisions, having conversations, and other activities. Super AI is like a super-brain for computers.

4. Rohan’s pet dog is an example of a general AI. A general AI machine can do all sorts of things, from solving problems to talking and learning new things on its own.

Conditional Statements in Java

Chapter Checkup A.

Fill in the Blanks.

B.

Write T for True and F for False.

1. Scanner 2. nextLine() 3. nested 4. else 5. object 1. T 2. T 3. F 4. T 5. T

C. Answer the Following.

1. Nest means within, and in Java an ‘if statement’ is referred to as being nested if it is stated inside another ‘if statement’ or an ‘if-else statement’.

2. The types of control flow statements for decision making in Java are: a. if statement

b. if-else statement

c. Nested if statements d. if-else-if statements

3. Difference between if and if-else statements: if statement

if-else statement

The if statement is used to execute a statement only when the given condition becomes true.

The if-else statement has two sets of code to be executed, whether the given condition is true or false.

if(condition){

if(condition){

//Task to be performed

//Task to be performed

}

} else{ //Task to be performed }

4. The if-else-if ladder statement is used in situations where multiple cases need to be checked. If one of the conditions in an if-else-if ladder statement is true, the statements defined in the if block will be executed.

If some other condition is true, the statements defined in the else-if block will be executed. Eventually, the statements defined in the else block will be executed if none of the conditions are true.

5. a. nextLong(): Reads a long value from the user.

b. nextFloat(): Reads a float value from the user. c. nextInt(): Reads an int value from the user.
