I would suggest two different places to help you get started here. First, did your instructor assign you some kind of poetry guide as part of your reading material? If so, that could be an excellent place to scan over forms and give you an example to start from. If not, try searching the internet for poetry forms, or forms of poetry. There are countless types; haiku, tanga, concrete, free verse, and pantoum just to name a few. Any format can hold any subject manner, so it all boils down to what feels right to you.
