Uncrafty person needs help!

I am not creative but I was roped into giving a vermicomposting demonstration this Saturday. I know the subject and have bought supplies but I cannot come up with any ideas for a display board. I have a small worm bin I will use as part of the display but I wanted to go beyond bare bones without it looking like a kindergarten science project. Would anyone be willing to share ideas for this board?

Here's what I have:

Large 36x48" trifold cardboard display board in white
Some 4/6 sheets of sparkly foam, assorted colors
googly eyes
8x11 red foam

I was going to use the red foam and eyes to make a large worm for the board and the sparkly sheets for letters WORM but I am stumped on what else to do. I've never worked with a display board before, I am from the poster board era.

I have an article from Mother Earth that I am going to print and distribute also but I just wanted something to catch peoples attention and draw them in and find I am sadly lacking in ideas.... Please, please help?
