Introduction to Selection and If Statements in Scratch Programming

This tutorial introduces the concept of selection in programming using Scratch. It explains how to use if and if-else statements to make decisions in a program. The example used is a simple program that categorizes users as 'old' or 'young' based on their age. The tutorial covers creating variables, using relational operators, and implementing decision-making logic. It concludes with running and testing the program to demonstrate how selection works in practice.

What is the primary purpose of selection in programming?

• To store data

• To perform calculations

• To make decisions based on conditions

• To display graphics

In programming, what does the 'if' statement allow a computer to do?

• Repeat actions

• Make decisions based on conditions

• Display text

• Store variables

What change is made to the Scratch program in the lesson?

• It asks for age instead of a number

• It calculates the sum of two numbers

• It asks for a name instead of a number

• It displays a welcome message

What is the difference between 'if' and 'if-else' blocks in Scratch?

• 'If' executes one action, 'if-else' executes two actions

• 'If' repeats actions, 'if-else' stops actions

• 'If' is for graphics, 'if-else' is for sound

• 'If' stores data, 'if-else' displays data

Which operator is used to compare if one value is greater than another?

• Not equal to

• Greater than

• Less than

• Equal to

In the Scratch program, what age is considered 'old'?

• 40

• 25

• 18

• 30

What does the program do if the age entered is more than 25?

• Ends the program

• Says 'You are old'

• Says 'You are young'

• Asks for another number

What is the purpose of using variables in the Scratch program?

• To store user input

• To display graphics

• To play sounds

• To repeat actions

What is the role of the 'else' part in an 'if-else' statement?

• To execute an action if the 'if' condition is true

• To display a message

• To execute an action if the 'if' condition is false

• To store data

What is the next topic to be covered in the following tutorial?

• Sound effects

• Graphics in Scratch

• Relational operators

• Loops in Scratch
