Scratch Programming

Lesson 2:

Learning intentions: I am learning how to create a project, move a sprite around using motion, save and retrieve my project.

Success criteria: I can create a project, move a sprite around the screen using the move command and save and retrieve my work.

Step 1: Click on ‘Learn how to make a project in Scratch’.

Step 2:

Start Scratch Program.

Sprite Editor lets you edit a Sprite’s Scripts, Costumes, and Sounds. Tool Box is like a bucket of Lego; it provides single script blocks for building combo script blocks.

Task 1 move Scratchy around the screen.

Click and drag Scratchy to the top left hand corner of the Stage.

Now lets see if we can move him around the stage in a circle.

The first command we need to drag to the Editor is

MOVE 15 STEPS

Change it to 300 steps so he reaches the end of the stage.

Click on the MOVE 300 command to make him move to the end of the Stage.

Now we need to turn him so he can move down the screen.

To do this drag Turn 15 degrees on the Script area

Change it to TURN 90 degrees.

Now click on the command TURN 90 DEGREES.

Scratchy should now have turned 90 degrees to face down the screen.

Move Scratchy to the bottom of the Stage by dragging the MOVE 10 STEPS Command into the Script area. DO NOT JOIN THE COMMANDS UP LIKE BUILDING BLOCKS YET.

Change the number of steps to 200.

Now click on MOVE 200 STEPS.

Scratchy should now be here:

Challenge: Can you make Scratchy TURN

Then WALK UPSIDE DOWN ALONG THE BOTTOM

TURN

THEN Walk up to where he started.

Use the Move and Turn Commands.

ANSWER:

TURN 90 DEGREES CLOCKWIZE

MOVE 300 STEPS

TURN 90 DEGREES CLOCKWIZE

MOVE 200 STEPS.

How do you get the Scratchy to face forwards again?

Answer: TURN 90 DEGREES Clockwize.

Now Join the each command together in twos like building blocks and click on them.

What happens?

Now join them together in 3s leaving one on its own at the end. What happens now?

What will happen if you join them all together and click?

Try it. Why does it look like nothing is happening.

Remove the last command off the end and try it now.

Saving our Projects

Where it says Untitled, delete that and instead give your project the title Lesson 1 Motion

To Save go to the Tool bar along the top and click on FILE then select SAVE now

Click on the Large SCRATCH on the top left hand side to return to the main menu.

To see your Project click on your name on the top right hand side. Then Click on Mystuff.

Your project should be there saved as Lesson 1. You can access your work anywhere there is an internet and you can create your own projects at home.
