By the end of the lesson you will…
Objective› Be able to create and understand simple
programs
Level 3 Level 4 Level 5
Create a simple program (script)
Predict the actions of a simple program (script)
Explain the stages of a simple program (script)

Scratch
A Scratch program contains sprites that ‘perform’ on a stage. Sprites and the stage have three properties or settings

Scripts
These are the instructions that control a sprite
Scripts are made from blocks
Over a 100 blocks in total
Sprites need scripts to perform

Costumes/Backgrounds
These are ‘outfits’ for a sprite
The stage can also have different backgrounds which can be changed

Sounds
Sprites and the stage can use sounds
Scratch lets you import recorded sounds or even record you own using a microphone

Adding Actions
To add an action you click on the object (sprite or background) and build the scripts up like Lego
