Explanation:

To solve this fill - in - the - blank problem about verb forms, we analyze each sentence:

Sentence 1: "We can all ____ to our school by helping to keep it safe and friendly."

• The modal verb "can" is followed by the base form of a verb. Among the given words "contribution" (noun), "contributing" (present participle/gerund), and "contribute" (verb, base form), we need a verb in base form. So we use "contribute".

Sentence 2: "Even things that seem small might make a big ____ to the school."

• The phrase "make a big..." requires a noun. "Contribution" is a noun, so we use "contribution" here.

Sentence 3: "For example, Brian is ____ by picking up litter during lunch break."

• The structure "is + verb - ing" is used for the present continuous tense. "Contributing" is the present participle form of the verb "contribute", so we use "contributing" here.

So the completed sentences are:

1. We can all $\boldsymbol{contribute}$ to our school by helping to keep it safe and friendly.
2. Even things that seem small might make a big $\boldsymbol{contribution}$ to the school.
3. For example, Brian is $\boldsymbol{contributing}$ by picking up litter during lunch break.
