Elementary students learn by doing with this hands-on resource about simple machines. The 15 investigations begin with a question that the student then explores. After exploring the types of simple machines (inclined plane, wedge, lever, screw, wheel and axle, and pulley), students evaluate common household items to classify them.

Each lesson lists the skills required, fast facts, vocabulary, materials needed, simple preparation, guided exploration, reflection and analysis, and home investigation for further activities. A reproducible Discovery Journal is included so students can record their observations. An assessment tool and literature connections are also provided.
