Civilizations have long used canals to move water, ships, cargo, and people from one location to another. The first canals were often trenches dug to bring water to crops. Some were dug to connect rivers or other bodies of water. Over the centuries, the techniques, technology, resources, and science used to construct canals has changed greatly. Today, canals all over the world help keep business booming and people moving! Readers will learn how engineers and scientists use STEM skills to bring canal systems to life--and how they make our lives easier. Diagrams, photographs, and primary sources help link this volume to both science and social studies curricula.

Ticks have been long known to transmit Lyme disease. However, there are more than 800 species of tick, and only two of these carry disease to humans at all! That doesn't stop tick bites from being a great annoyance, especially considering they're caused by a tick sucking your blood! Often grouped with another real-life vampire, the flea, ticks use this blood to complete their life cycle while fleas use it for food. Surprising facts about the life cycle, habitat, and feeding habits of these bugs engage readers while full-color photographs bring these tiny creatures into clear view.

Full-color photographs introduce these bloodthirsty birds, and fact boxes provide additional science information to enhance the main content.

We use machines every day, but most of us don't understand how they work. When they break down, most of us have no idea how to fix them. Mechanics are the masters of machines.

They often work long hours, sometimes in bad weather, to get us where we need to go. Your readers will see that mechanics keep our world moving and growing.
