Unit 2 Debug it!

HELP! CAN YOU DEBUG THESE THREE SCRATCH PROGRAMS?

DEBUG IT! 2.1 http://scratch.mit.edu/projects/10437439

In this project, the Scratch Cat should pace back and forth across the stage, when it is clicked. But the Scratch Cat is flipping out – and is walking upside down! How do we fix the program?

DEBUG IT! 2.2 http://scratch.mit.edu/projects/10437476

In this project, when the green flag is clicked, the Scratch Cat should saw ‘Meow, meow, meow!’ in a speech bubble and as a sound. But the speech bubble happens before the sound – and the Scratch Cat only makes one ‘Meow’ sound! How do we fix the program?

• Keep track of your work! This can be a useful reminder of what you have already tried and point you toward what to try next.
• Share and compare your problem finding and problem solving approaches with a neighbor until you find something that works for you!
• Help your neighbor!

If you have finished with the debugging, you can go back to your Simple Chase Game project and keep working on it.
