World of Machines - An Introduction to Simple Machines for Young Scientists
Takes students on a learning journey into the six types of simple machines (levers, wheel and axle, pulley, inclined plane, wedge and screw) as well as matter and mass, density, inertia, force, force and motion, gravity, friction, and work. Conclude with a study on making a compound machine. Recommended materials include a standard size brick, block of wood, 12” ruler, spring scale, small box, small cart, 500g and 1000g weights, large pry bar, 2x4 wood, meter or yard stick, bind clips, wooden dowel, single wheel pulleys (2), double wheel pulleys (2), 1” thick board, wooden wedges, large wood screws, pine, screw driver, hammer or mallet, and other household items. A complete list is included in the Teacher Resources material.
World of Machines: An Introduction to Simple Machines for Young Scientists is an exploration of basic laws of physics, and the functions and uses of six simple machines. Students are introduced to simple fundamentals of matter, mass, density, inertia, force, the laws of motion, gravity, friction and work. They learn how machines reduce effort, then focus in on six simple machines: the lever, wheel and axle, pulley, inclined plane, wedge and screw. Let's Do This! activities give students opportunities to test out basic physics concepts in the real world and to experiment with each simple machine. The result is a grounding in the uses of simple machines to reduce effort and make it possible to carry out tasks that would not be possible without them. This can be an empowering experience!
Hands-on and self-pacing, this new science series meets the learning needs of diverse learners. Courses are well-written, engaging, and focus on mastery of information. With the flexible, independent pacing, students should expect to complete each course in 10-17 hours, with an end of unit exam to ensure mastery. Home Study Kits include several components: the softcover Student Text, the Student Learning Guide, and Teacher Resource Packet. Written from a religiously neutral perspective, so no evolution or intelligent design is discussed.
Abundantly illustrated, the textbook is written to the student and provides many hands-on activities. Students will appreciate the well placed spacing of text and graphics. The layout is truly inviting and not visually overwhelming. The Student Learning Guide supports independent learning by giving students the course purpose and basic instructions to follow. Following this brief introduction, the guide provides steps to complete in order. Steps cover chapter readings and activities. After completing each step, lines are provided for students to initial, and on occasion, the teacher/parent also verifies the step is completed, and initials. Activities vary and include drawing and labeling in a science journal, finding related items, discussing with the teacher, and related hands-on activities or experiments. See individual courses for more detail. The Teacher Resource Packet includes the overall publisher philosophy called Swimming Upstream, background information with materials list, the end of unit exam, exam answers, and a Certificate of Achievement. Components are sold in sets called Home Study Kits and are not available individually. Topical Home Study Kits are available individually or in grade level packages that align with the publisher’s recommended sequence:
