It Takes Guts, How Your Body Turns Food Into Fuel (And Poop) is seemingly custom-made for the reading level, humor, patience, and temperament for sixth-grade students. It’s also intelligent enough to be appreciated by those older readers, even those who have no idea what chyme it is. That’s another reason that middle school ages will enjoy It Takes Guts, it’s funny and laden with puns or other learning pneumonic devices. The puns in the book are so sublime that some readers won’t even get them, but they’ll know that they’re there to make the book more palatable.
