“Hyde and Shriek” by David Lubar; Starscape, $14.99.

Science teacher Ms. Clevis is one of the most popular teachers at Washington Irving Elementary School, which is gearing up for the school science fair.

Then one morning she accidentally mixes some chemicals into her breakfast smoothie. Suddenly, she finds herself switching back and forth between a sweet-tempered sixth-grader named Jackie and evil substitute teacher Ms. Hyde. (Ms. Hyde enjoys tormenting children in the halls but her true triumph is an incident where she takes kids on a field trip in a dumpster hitched to the back of her car and leaves them stranded without their shoes, so they have to walk home barefoot.) Will Jackie-Ms. Hyde be able to switch back to being Ms. Clevis, who is not all good or all bad but somewhere in between? Or will Ms. Hyde take over and create terrible havoc at the science fair?

This hilarious update of the Dr. Jekyll and Mr. Hyde story is the first installment in a new “Monsteriffic Tales” series from the author of the popular “Weenies” story collections.

While the noses of many dogs are wet, plenty of dogs have dry ones. What keeps a dog’s snout moist? No one knows for sure. One theory says that the wetness comes from mucus produced inside Fido’s nose. Another hypothesis suggests that because dogs lick their noses all the time, saliva keeps their noses moist. Despite popular belief, a warm nose does not mean a dog is sick.
