In today's lesson:

You will be remixing your Variable projects from Lesson 11.

Objectives

Students will be able to...

• use conditionals using AND/OR

• explain the concept of conditionals.

• apply knowledge of conditionals.

• enhance a variable program with conditionals.

• utilize conditionals and loops appropriately to build an algorithm.

• use descriptively named variables to store data.

• manipulate data stored in constants and variables.

​Essential Question

How can we use conditions and variables to direct the flow of our programs?

​ Conditionals and Variables

Open Ended

What happened in this program? (What has to happen for things to kick off?)

What is a "conditional"?

A piece of code that needs to check if something is true or false before it runs.

Multiple Choice

In Basketball, what are good variables?

• Score

• If the team wins

• If the team loses

• Whether the team listens to the coach

Multiple Choice

A variable is used to...

• tell if an expression is true or false

• repeat the same instructions over and over again

• store information to be referenced and used by programs

• store information so that it is never used in the program

Multiple Choice

Statements that can only run under certain conditions or situations such as: if the seat is taken, then move to the next available seat.

• conditionals (if/then statements)

• variable

• abstractions

• binary

Multiple Choice

The information that’s stored inside a variable, such as a number or a name, is called what?

• Variable

• Value

• Object

• Conditional

Today's Assignment

Today and tomorrow, you will be working on improving your food game. Go to your completed game project (click the my stuff folder in your Scratch account) and save a new copy of it in Scratch so that you don't lose that particular project. You will need to upgrade it by including the following:

• add more food sprites (eg. traditional/native foods) by importing images (crawfish, gumbo, etc.....)

• play a sound when a food item is clicked (eg. cheer when healthy, boo when unhealthy)

• turn the project into a game where the foods move around randomly on the screen and/or disappear when clicked

• add a new variable named life points

  • If the number of nutrition points drops below -4, subtract a fixed number of life points. If the number of points is greater than 9, then add a fixed number of life points

• A message about being nutritious if the number of points becomes greater than 9

• A message about eating healthier food if the number of points becomes less than -4
