The Case of the Barfy Birthday (Science Detectives, No. 4)

In this fourth clever chapter book starring Drake Doyle and Nell Fossey, real science is seamlessly woven into four exciting cases, including a mysterious food-poisoning epidemic and a spooky tree-house ghost.

The snappy dialogue and wacky scenarios are perfect for middle-graders, who will enjoy discovering the appendix of science activities, which focus on such concepts as epidemiology, code breaking, phases of matter, and simple machines. Each corresponds to a case in the book and will have readers scrambling for their own lab notebooks and detective gear!
