The annual Research Fair is today. You and your classmates have prepared presentations on topics of your choosing that you researched and you get to present to family and friends today! The problem is, you went into the gym to check on your project and it is a mess! Posters are knocked down, papers are everywhere, and mysterious footprints line the gym floor. Who could’ve made this mess? Can you piece together the evidence to find out who made this mess and clean it up in time before the Research Fair begins?
