"Effect" is most commonly used as a noun to refer to the consequence or result of some activity. The project title, "The Effects of Eating Ice Cream Too Fast," uses "effects" as a noun to refer to the result of eating ice cream too fast (the activity).
"Affect" is most commonly used as a verb to describe a change to something else. For instance, the project title, "Eating Ice Cream Too Fast Can Affect Your Brain," uses "affect" as the verb describing a change to "your brain." Notice the presence of the helper verb "can" just before "affect"? Big clue as to whether to use a noun or verb here!
Yes, there are some exceptions; but only in rare cases and not likely to show up in your project title. Remember, if you need a noun, use "effect." If you need a verb, "affect" is the one. (Hint: If you're not sure, ask an English teacher. They've all promised not to bite!)
