Programming with Scratch: Using Relational Operators and Selection Statements

This tutorial covers programming in Scratch, focusing on using if statements and relational operators to make decisions based on user input. It explains relational operators like greater than, less than, and equal to, and demonstrates how to implement them in a Scratch program to evaluate age. The tutorial also includes a practical example of building and testing a program that categorizes age inputs as young, old, or perfect.

What is the primary purpose of using selection statements in programming?

• To display graphics

• To store data

• To make decisions based on conditions

• To perform calculations

Which of the following is NOT a relational operator in Scratch?

• Greater than

• Multiply

• Less than

• Equal to

How can you remember the 'less than' symbol using your hands?

• Left hand is less than

• Right hand is less than

• Neither hand is used

• Both hands are equal

In the Scratch program, what is the output if the age entered is exactly 25?

• No output

• You are still young

• You are old

• 25 is the perfect age

What happens if the age entered is less than 25 in the Scratch program?

• No output

• You are old

• You are still young

• 25 is the perfect age

Which statement is true about the use of multiple if blocks in Scratch?

• They allow for more than two conditions to be checked

• They can only check one condition

• They are used for looping

• They are not used in Scratch

What will the program output if the age entered is greater than 25?

• You are old

• No output

• You are still young

• 25 is the perfect age
