Start a new Scratch project - "File" and then "New"
Delete the cat sprite; right click and select "Delete".
Add a new sprite by clicking on "Paint new sprite".
Use the "paint" facility to make a small ball.
Use the "elipse" tool to draw a circle. Make sure that you use the filled elipse and if you hold "shift" while you draw it will be a circle not an elipse (although a circle is a special elipse mathematically speaking).
Press "OK" to save the sprite.
The sprite is called "sprite1" and we need a better name than this.1. Screenshot your project so far and describe creating a sprite using paint.

To make the bat create a new sprite by clicking on "Paint new sprite".
Use the line tool to draw a short line parallel to the bottom of the screen. Use the checkered squares to help you to get the line level and straight.
Rename the sprite as "paddle"2. Screenshot your project so far and describe adding the paddle.
Now give the ball this script. The ball will be set to the centre of the screen (0,0) and pointed in a random direction and then iot will move "forever".
Give the paddle this script.
See if you can make the ball bounce on the paddle.3. Screenshot your project so far and describe making the ball bounce on the paddle.
You will need a variable to store the number of lives that you use up (if you miss the ball!)
Make a variable called "Lives".
Lives should be visible on the screen.
Add this script to the stage. This set the number of lives to be 3 at the start. The idea is that every time that you miss the ball you will lose a life. When you have no lives left, the game will end.4. Screenshot your project so far and describe how the project keeps score.
Now create a floor for the ball to land on if you miss.
Create a new sprite and draw a straight line the width of the screen. Again use the checkered design of the background to make the line straight and level. Choose "Red" as the colour so that the ball can recognise when it has hit the floor.
This is the line, it will appear in the middle of the screen. Change the name of the sprite to be "Floor".
Add this script to the floor to make it move to the right place by itself.It needs to be lower than the paddle that you made earlier.
Screenshot your project so far and describe changing the background of a project using paint.5. Screenshot your project so far and describe how the floor was added.
Note that when the ball hits the floor it will start at the centre of the screen again.6. Screenshot your project so far and describe how the project keeps score when the floor is touched.
Change the script so that the game counts how many times the ball has bounced onthe paddle and then at set intervals the ball speeds up..7. Screenshot your project so far and describe how the ball can be made to speed up.
Turn the game through 90 degrees so that the bat and the floor is on the right hand side of the game as is the wall. Add a second bat and floor on the left hand side to be controlled by another player and make it a two player game.8. Screenshot your project so far and describe how you made the two player game.
