Hands-on learning at it best! The K'NEX Education Intro to Simple Machines: Levers & Pulleys set is designed to introduce students to the scientific concepts associated with two types of Simple Machines – levers and pulleys. Students are provided with the opportunity to acquire skills using a hands-on, inquiry-based approach to information and concepts. Working cooperatively, students are encouraged to interact with each other as they build, investigate, discuss, and evaluate scientific principles in action. The

Teacher's Guide provides the information and resources needed to build students' understanding of scientific concepts and channel their inquiries into active and meaningful learning experiences. Extension activities that can be used to explore the concepts more deeply are also included.
