Journal before Exihbition

I am excited about exibition, but I am worried that some people are going to talk and distract other groups from doing their work. I like our main idea for this years exhibition, I think it has to do with the Earth and how we are in our minds. The only thing that I am worried about, is how we are going to present our idea and our projects to the other fourth grade and other grade students. That is what I am thinking about exhibition.
