Conditional Statements

Conditional Statement: A condition and a result. If the condition is true, the result occurs, if false the result does not occur.
 

Condition: A requirement that must be true for a result to occur.
 

Result: An outcome if a condition is met.

Describe this conditional

Variables

Variables in scratch hold a value until it is needed later. 

Variables can be strings (words or sentences) or numbers, and can change. 

When should we use variables?
