Well, in a Harry Potter potion class fanfiction, you could have a plot where a new student from a very different magical culture joins the class and has their own unique approach to potion - making. This could lead to some interesting exchanges with Snape or other students. Or perhaps there's a mystery surrounding a particular ingredient in a potion that the students have to figure out. It might be that this ingredient is being hoarded by a dark wizard, and the students' discovery of it puts them in danger. Also, a fun idea could be that a student accidentally switches two ingredients in a potion and creates a brand - new potion with unexpected but useful effects.
A great plot for Harry Potter potion class fanfiction could be centered around a cursed potion ingredient. Say, a student finds an ingredient that seems normal but is actually cursed.

The students then have to figure out how to reverse the curse before it spreads throughout Hogwarts. Another idea is a story where the potion class is combined with a time - travel experiment. The students end up making a potion that sends them back in time to when the founders of Hogwarts were creating the first potions, and they learn some ancient secrets of potion - making. And, you could have a story where a student tries to create a love potion but instead makes a potion that reveals people's true feelings, which causes all sorts of drama in the class.
One idea could be a potion that reveals long - lost family secrets. For example, a character discovers through the heritage potion that they have a connection to a powerful but forgotten wizarding family. This could lead to a whole new adventure as they explore their new - found heritage.
One idea could be a situation where a group of Hogwarts students accidentally use the Polyjuice Potion and swap identities in the middle of an important exam. It would lead to chaos as they struggle to answer questions in each other's forms.
Well, perhaps a character uses the potion to turn into a teacher to change grades in order to get a friend out of academic trouble. They end up having to teach a class while in the teacher's form and hilarity ensues as they struggle to keep up with the subject matter.

One idea could be a story where a young, inexperienced wizard accidentally creates a super - powerful luck potion.

Well, there are several interesting characters for Harry Potter potion class fanfiction. Snape, of course, as he is the potions master. But you could also include some of the house - elves.

He might visit the potion class to show the students some rare ingredients he has collected from the Forbidden Forest. And then there are the ghosts of Hogwarts. The Bloody Baron could be lurking around the potion class, and his presence could add an eerie atmosphere.

Also, it could be that a dark wizard wants to use this potion to embarrass and control the Hogwarts students, which then leads to a battle of wits between the good guys and the bad guy.
