Purpose: Students are introduced to debugging a problematic programs.

Journal: Your grandparents call you and say that they are unable to get music to play on their speakers. What could the problem be? How will you guide them to a solution?

Activity: Log on to Code.org U3Ch1L6 Debugging: Gradesheet

Debugging Process:

1. Describe your problem (what is happening).
2. Hunt for the bug.
3. Try small solutions and see how they effect your code.
4. Document what you learned.

Hint: Use the text visualizer: Turtle speed / Text mode / Turns Golden as it plays.

Level 1 – Debug Program: Strings need to Go In Quotes: ""

Level 2 – Debug Program (My Message): Strings need to Go In Quotes: ""

Level 3 – Run and Fix (Smiley Face): The range of values for the random numbers is too large.

Level 4 – Run and Fix (Music Player): Event handlers (onEvent) should not go inside other (onEvent) blocks.

Level 5 – Run and Fix (Red Button / Blue Button): The program does not "Run." Imagine that when you select the Blue Button, the Red Button changes size. Then when you select the Red Button, the Blue Button Changes size. Now view the program...can you see the problem? How do you fix it? Write it down.

Practice / Level 6 – 3 programs...Run and Fix: 

• Farm sounds -Debug this program to use the correct sound and text when the user clicks each animal.
• Club Fair App - Add code to the program so that the "Go Back" button takes the user back to the home screen.
• Mood Minder App - Run this program to see how it works. Then add code to the app to make all the buttons work.
  • Audio to use with "Excited."  Or, copy and paste this link into your program:    https://music.youtube.com/watch?v=szWX1HhMZvI
  • Image file to use with "Excited."     Or, copy and paste this link into your program:  https://free-images.com/lg/0793/daisy_flower_blossom_bloom_54.jpg
