hi all, i have a quesstion, please help me

[badminton]

So originally I chose to test if you could substitute nonionizing radiation (uv radiation) for ioninzing radiation when performing food irradiation. My teacher didn't know anyone with a lab so she chose this poject for me, which is only watching grapes that have been treated with 2 different preservatives and 1 organic. Last year I went to the state science fair and I didn't place so this year I'm hoping to get to state again and place as fourth. Which one do you think would i most likely win with? If it was my first one then wish me luck trying to last minute fine a college to work with. I should've went behind my teachers back to find a college in the first place because that's what all the other people did with their projects at the fair. They contacted all the colleges they could. Someone please help me I've just been stressing out a lot and I just don't think the project my teacher wants me to do will get that far.

It's up to you. But I suggest you chose one that will give info to the judges and interest them. I think you should choose the one you went with. The first choice.
