the bouncing turtle
  • Click the Drawing Center.
  • Click the square.
  • Click the line thickness.
  • Click the color blue.
  • Place the mouse in any corner and drag out a blue border.
  • Click on the blue again and enter "right 180" - we are telling the turtle to "about turn" whenever it runs into the color blue.
  • Click on the button on the Tool Palette, type "go" and click "Many times" and press "OK".
  • If you now try your new "go" button, the turtle says "I don't know how to go". We have to teach it to "go" and all I have in mind is: 
    
Ctrl-f (Command-f on a Mac)
to go
  forward 1
end
Ctrl-f (Command-f on a Mac)
Now try the "go" button and the turtle should bounce up and down. Note that you can stop it by pressing "go" again.

Note also that you can drag the turtle to a new position and that you can turn it by dragging its head.

further ideas:
  • make the bounce more interesting by adding a random element - get back to the "Instructions for blue" and change the instruction to 
    right 180 left random 20 right random 20
    You will need to press to get back to the Command Center.

  • give the turtle a challenge - add some blue shapes
Give yourself a real challenge! This turtle is bouncing around like a ball on a pool table.
