Conditional statements like if-then-else are the way you code your program to make decisions. It's very similar to how we make decisions, like if it is going to rain, then I should take my umbrella, else if it is sunny, then I should bring my sunglasses.
Unplugged Activities:
if I land on a color,
then perform the action associated with that color
if this character bumps into another character, then run the attached code (which is disappear in this example)
if the sensing condition is true (like touching Apple sprite) then run the attached code (which is say Yum! in this example)
