Join the Sassafras Twins as they travel to fascinating locales to learn about the human body.
Together, you will learn all about the human body as Blaine and Tracey zip around the globe. In the book, you will visit locations like:
An ancient tomb in Ethiopia to learn about the skeletal system;
A garbage landfill in Texas to study the digestive system;
And a bistro in Italy to experience the five senses!
The twins will meet a variety of local experts who help them along the way to learn about the different systems of the human body.
