When my DS was in 8th grade,, he did a science project. Title;; "WORMS EAT MY GARBAGE" He used Red Worms as his workers.I’ve decided to add a worm bin to compost our kitchen scraps
He aced out in Regional Finals, and took his science project to State Finals in Springfield Illinois.
I don't have any digital photos from there ,(before digital cameras time) but here is a pix from online to give idea how the Science Fair is presented.
He got a lot of his information from this book.
