What does application in a science fair project mean?
An application is how your science project could help someone in
a real life situation. For example, a simple science project like
which paper towel brand is stronger, the application for this
project could be "If someone in the world wanted to soak up more
with a paper towel, then that person could use 'this' brand instead
of 'this' one because the other towel brand is stronger and soaks
up more liquids.
