Can I Scream Now?

This science teacher gave us an assignment to do where we have to find things in life and bring out the science from it. I came up with a few great ideas and he told me that won't work. What the heck am i supposed to do? 

I feel like over the years my creativity has increased but i'm not getting the chance to show it. I am so frustrated right now and don't know what to do. Our group got a dumbass topic on herbal medicine which is total crap. I want to do something more fun.

My advice: If you have a science project to do and the topic sucks, scream! Don't hold it in. And after you are done with screaming, suck it up and do your part in the groupwork and get it over with.
