04- Coding Computing Wonders

Computer programing or coding is the process of telling a computer to do
certain things by giving it instructions. There are two types of programming:

1. Visual or block programming.
2. Syntax or textual programming.

You will learn how to give instructions to the computer using block programming.
Code.org is the platform where you will the basics of block programming.

4.3 Artist: Sequence

In this lesson, you will learn how a code executes instructions. In a program, the
instructions are executed line by line which means the first line of instruction will
run before the second line and so on.

4.4 Getting Loopy

Let’s consider you want to move a character three steps forward, your normal
approach will be to connect three move forward blocks one after the other, and
you will get the desired result. But let’s say you have to move the character a
hundred steps forward, now it’s a bit difficult to place hundred move forward
blocks in your code. There must be a better way for doing this task. That’s where
loops come in. Loops are simply repeating blocks. If you want to perform a task
multiple times you will use loops. Let’s practice loops!

4.6 Bee: Debugging

What do you say when a program or block of code does not give you the right
results? You will say the program is incorrect or wrong. But in programming when
there is an issue in your code you say the code has errors. Now you know what
errors are let’s discuss what you call when you remove errors from your code. The
process of removing errors from your code is called debugging.

In this lesson you will be presented with a block of code that will have some errors
in it, your task is to remove the errors and get the desired result.

4.7 Bee: Conditionals

Let’s discuss what are conditionals? Suppose you want to perform a task only when
a certain condition is met and if the condition is not satisfied the program should
do nothing! To perform this function, you need conditionals. Conditionals are
simple coding blocks that only run when the condition inside them is met. For
example, keep collecting nectar if the nectar value is greater than one. Let’s dive
into the lesson!

6. Safety Online

05- Digital Literacy Computing Wonders

It's time to discover the amazing new Internet world, so grab your backpack and
let's go! You will learn what the Internet is and how to conduct an information
search. You're going to learn how wikis can help you increase your knowledge. But
be careful—virtual or not—every community has laws that you must abide by.
These guidelines set your conduct, but they also safeguard you and keep you
secure.

5.1 Internet Traffic Light You have to be safe when
visiting a website. But how?
What is a Green website or app?

1. The app or website that is right for you. You will get to know!
2. Right things for you to see and do.
3. Appropriate in every manner.
How to know which website or app is “Green” for you? What is safe or unsafe for
you?
Just read the questions carefully.
Discuss it with one or more person before taking decision.

What is a Yellow website or app?

1. A website which seems not right, or seems fishy.
2. Which asks you about your personal information i.e. your address etc.
3. The site which you cannot understand or it is hard for you to read what’s

in it.

What is a Red website or app?

1. It is quite similar to the Yellow one but little more dangerous.
2. A website or app that doesn’t seems right to you at all.
3. A website which you have not opened by your choice or got there by any

link or by mistake.
4. That contains inappropriate videos, pictures, links or anything which isn’t

for you or for the adults.
A website that allows you to chat with strangers without your consent or without
you knowing the other person you are chatting with.

5.2 Password Power-Up Strong password can protect your
privacy.
5.2.2 Password

A secret word, phrase, or group of numbers that a person must know to be allowed
to enter a place or use a computer system.

5.2.3 Phrase Password Tips to Remember

A phrase is a small group  Start with a memorable phrase.

contain a verb (as soon as  Never use any private identity information in your
a verb is included, the
group of words become a password.
clause).  Create passwords with at least eight characters.
 Use letters, numbers, and symbols in your

password.

5.3 Accessing the Internet

Because it is so easy and affordable to access the Internet, you can visit any
website and quickly and simply search for and locate any information you need. As
a result, the Internet is like a gigantic library. All you need is a computer, with an
Internet connection, and a program known as a web browser.
Microsoft Edge, Google Chrome, Opera, Safari, and Mozilla Firefox are a few
examples of web browsers. Every machine running Microsoft Windows will have
Microsoft Edge

Fig 5.2

62

05- Digital Literacy Computing Wonders

There is another way you can open the web browser i.e. to click the browsers icon
on the taskbar.

to reload the
web-page.

5.3.1 Searching on the Internet

Searching any information or anything directly from the address bar is not a
smart way. We always use a search engine instead.

Fig 5.5

Fig 5.6 > Kiddle.co is a search engine
for kids.
> You can search for any
information here, anything
from the world.
> Lists of result is here after
searching for plants.

63

05- Digital Literacy Computing Wonders

You can see thousands of results after searching something on internet. It can
vary to a large number of pages.

Choose pages
for best results.

You can get help from search engines
to find images, information, and news.

Fig 5.7

5.4 Knowledge Treasure Sites

5.4.1 Virtual Library Some examples of Wikis are:

The internet is like a Wikipedia → encyclopedia
big dictionary and Wiktionary → dictionary and thesaurus
vocabulary in your Wikisource → library
hands, you can search Wikinews → news site
for literally anything Wikibooks → texts and manuals bank
over internet. There Wikispecies → species directory
are some websites,
virtual dictionaries and
encyclopedias for free.

Wiki is a type of website written by a lot of experts,
from the Hawaiian word wiki, meaning "quick". They are
continuously updated and are available in many languages.

Almost all the wikis contains images, videos, clips and gives you a search box to
search for it.

The most popular amongst Wikis is the Wikipedia,
it’s the biggest free encyclopedia for all.

64

05- Digital Literacy Computing Wonders

> Open a browser and visit www.Wikipedia.com. (1)
> Type anything you need to search in the search box. (2)

> Then click the search icon or Enter. (3)

Fig 5.8

5.4.2 Copy Information

Copying text from Wiki is also possible and very easy. You can copy any
information or text you want for yourself.
To copy and paste text:

1. Open Wikipedia, search for anything, and find your text.
2. Select the text, right-click on the mouse and copy the selected text.
3. Paste the text anywhere like Microsoft Word or WordPad.

Fig 5.9

65

05- Digital Literacy Computing Wonders

Fig 5.10

5.4.3 Respect the Work of Others

Without the consent of the authors of the content, it is improper to copy and use
any text or images from the Internet. Would you appreciate it if someone used a
project you uploaded to the Internet as if it were their own? Obviously not.
Always credit the creator of an idea or the source from which it was taken when
borrowing something.
If you copy text from Wikipedia you have to add “Plants." Wikipedia.Online. at
the end.

5.5 Be Polite

5.5.1 Be Nice

Be polite! You may communicate with individuals all around the world through the
Internet, which also serves as a source of information. However, you must behave
politely both online and in person.
The term "Netiquette" refers to a set of guidelines for appropriate behavior
online. The term "netiquette" refers to the manners and practices that are
appropriate on the Internet, such as what to communicate or post and how to
conduct yourself.

The Golden Rule of Netiquette: do unto others online as you would have done to you.

Today, many schools and universities around the world teach their
students about moral and responsible behavior on the Internet.

66

05- Digital Literacy Computing Wonders

5.5.2 Communication Manners

When communicating via instant messaging, email, blogs, and chat rooms, you must
use caution and good manners. Don't engage in conversation with strangers. Your
parents have advised you against interacting with strangers. On the internet,
heed this advice as well.

5.5.3 Using E-mail

Always use a subject title and check your emails for spelling errors. If no one
responds right away, don't be concerned. Be tolerant! They can be busy or they
might not have seen your message yet. Email messages asking you to forward them
to your friends should not be forwarded or responded to. Beware of these
messages! They may actually cause harm. After showing your parents, erase the
documents.

5.5.4 Using Blogs

You must respect to the blog's creator's regulations and keep your messages
brief. Avoid conflicts, and don't point the finger at anyone. Never use foul
language, and be sure to express your viewpoint clearly. Always give others a
chance. Give as much information as you can if a friend wants assistance with a
website.

5.5.4 Using Chat Rooms

Use emoticons to express your feelings. People you communicate with online may
live all over the world, and their culture, language, and sense of humor may be
very different from yours. So, when using humor, sarcasm, or slang, exercise
extreme caution.

Before closing the chat, always say goodbye and double-check that your friend is
also leaving. This is essential when communicating with someone who lives a long
distance away.

Keep in mind that anyone can read your posts in a chat room, even your teachers.
So, avoid sending messages using inappropriate language. You should not send
heated messages ("flames"), even if you are provoked. Also, you shouldn't share
any information that you wouldn't share with a stranger.

Don't give any personal information to people that you don't know, especially if
someone asks for your age, phone number or address. If someone does, stop
talking to them at once and tell your parents.

67

05- Digital Literacy Computing Wonders

5.6 Safety Online

The internet is a great source of information, but it can also be a dangerous place
if you don't know what you're doing. There are numerous dangers to avoid, just
as there are in real life.

Viruses are the most common problem on the Internet. A virus is a program that
infiltrates your computer and attempts to harm it. Your computer becomes "ill,"
just as you become ill when you are careless and do not listen to your parents. A
virus may attempt to delete files or steal personal data.

The most important tool for protecting your computer is an antivirus program
that detects and eliminates viruses. Because new viruses emerge every day, an
antivirus program must always be kept up to date.

An antivirus program protects your computer. What should you do
to protect yourself?
