Computers help you work faster, but to make them do what you want, you need to
give clear instructions called codes. You’ve already learnt about Scratch Jr and

now it’s time to try Scratch 3. With Scratch 3, you can bring your ideas to life by
arranging colourful blocks to create exciting projects.

INTRODUCTION TO SCRATCH

Scratch is a free and fun way to learn coding. You

can make your own stories, games and cartoons by
snapping colourful blocks together. It’s easy to use Scratch was created by

and helps you see how computers follow instructions Mitchel Resnick at the

ADVANTAGES OF SCRATCH

Scratch is the preferred language for young learners for the following reasons:

Commands are block-based, so there is nothing to remember.

Blocks can be dragged and snapped to build programs.
They fit together like puzzle pieces.

Each block has its own colour and group for easy finding.
Projects can be shared with others.

Suppose, you have to code an environmental conservation game in Scratch
where players work to protect endangered species and preserve ecosystems.
What environmental challenges would they tackle and how would they make
a positive impact?
