Bernhardt, Carolyn

This series clearly explains engineering principles through hands-on projects. Six-page introductions define each engineered structure, briefly describing its construction, uses, and different types. Five or six activities follow, and "Digging Deeper" sidebars expand on the science involved. Simple directions, inexpensive materials lists, and plenty of helpful photographs make this series a good choice for budding engineers. Each book concludes with a three-question quiz. Glos.
