Mind Games by Jeanne Marie Grunwell is a fantastic fictional novel written as a scientific journal from the point of view of a group of 7th grade students. It explores the scientific process and has a character every student can relate to. It's funny, emotional and most importantly scientifically sound (although the topic of their study is ESP- the author does a good job at remaining objective). It's a quick read- I love to do it right before Christmas Break or after end-of-year testing. I also like to have my students conduct the same "experiments" (all you need are dice and index cards).
