U3Ch1L5_Intro To Programming
Purpose: Students use and modify a series of simple apps to get familiar with a small set of programming commands. 

Activity: Log on to Code.org U3Ch1L5 Intro To Programming:
Guidelines:

• Code is running one line at a time.
• Strings need to go in quotes. Numbers do not need to.
• Yellow highlighting shows you which line of code is running in either block or text mode.
• The turtle slider changes the speed at which the code runs. At full speed (all the way to the right) there is no longer any highlighting.
• If there is an error in your code, a yellow triangle will appear…fix it , then Reset and Run!

Level 1 – Console Log: Run the Program - View the result in the Debug Console Window

• Add two lines of Code: One with a string of text and one with a number.

Level 2 – SetProperty: Run the Program – What is the difference between “Console.log” & “SetProperty”
“Console.log”  prints text in the Debug Console.
“SetProperty” changes the properties of elements on the screen.

• Add one “Console.log” & one “SetProperty” to the program.

Level 3 - onEvent (1): Run the Program – Explain how the “onEvent” block works? Be Specific. Do commands outside “onEvent” run different from those inside?
“onEvent” acts like a Conditional or If/Then statement.

• "onEvent" makes the program respond to the user. You can add code inside of it that will only run when something happens.
• Changing the second input changes the type of interaction that will make the code inside the "onEvent" run. 
• Code outside the "onEvent" runs right away. Code inside an "onEvent" will only run when the event happens.
• Even if code is after an "onEvent", it will run first if it's outside of any "onEvent"
• Add one command inside the  “onEvent” & one command outside.

Level 4 – on Event (2): View the Program and predict what will occur. Enter your prediction in the form field. Now, Run the Program – What allowed the screen to change?

Level 5 – setScreen: Run the Program – What allowed the screen to change?
A “setScreen(screenId) inside an onEvent allows the user to navigate between app screens.

• Add one command inside the second “onEvent” to set on property of the “homeIcon”.

Level 6 – playSound: Run the Program – How does “playSound” work? What does “//” do?
“playSound” will play a sound you pick from the Sound Library.
“//” are comments and don’t run but are used to help you understand your code.

• Add code so the dog button makes sound too.
• Change the message when each button is clicked.

Level 7 – randomNumber: Run the Program – How does “randomNumber” work?
“randomNumber” allows the computer to generate a different number.

• Challenge:
  • Make the birds move around the entire screen.
  • Add “mouseOver” & “click” to the program.
