Answer 2

This depends on what you want to do. There are millions of things. but, if you only have a month. Do you want somthing easy? Or somthing inventive?

I say, somthing with radish plants, they grow super fast. Maybe test them with diffrent colors of light. Or, diffrent fertilizers.

There are lots of things. Try somthing that you are intrested in?
