The 11 lessons in this module introduce students to single and compound pulleys and gear systems. Students investigate, design, and construct various pulley systems and gear mechanisms.Also included:materials lists activity descriptions questioning techniques activity centre and extension ideas assessment suggestions activity sheets and visuals The module offers a detailed introduction to the Hands-On Science program (guiding principles, implementation guidelines, an overview of the skills that young students use and develop during scientific inquiry), a list of children's books and websites related to the science topics introduced, and a classroom assessment plan with record-keeping templates.
Describes many different kinds, uses, and benefits of pulleys. Provides examples of pulleys by showing a flagpole, a crane, an elevator and window blinds.
Text and photographs present pulleys and their function as a simple machine.
What do flagpoles and some window blinds have in common? They use pulleys to perform work! Pulleys are simple machines. They help us to do jobs more easily. But don't take our word for it. Put pulleys to the test with the fun experiments you'll find in this book. As part of the Searchlight BooksTM collection, this series sheds light on a key science question―How Do Simple Machines Work? Hands-on experiments, interesting photos, and useful diagrams will help you find the answer!
Provides examples to describe pulleys as simple machines that make lifting, pulling, and moving easier.
What pulls a flag up a flagpole? How does a bicycle chain help the bicycle move? What makes an escalator move? Pulleys and gears are simple machines that can be used to make other machines work. When you take an escalator, ride in a car, use a fishing rod, or wear a watch you are using pulleys and gears. Pulleys and Gears explains what these machines are and how they help you do everyday things.
Pulleys are part of our daily lives, from elevators to giant cranes. We wouldn't even be able to raise the flag without the powerful pulley. Readers will learn all about this important, simple machine through detailed pictures with thorough annotations. They'll explore key engineering topics and learn about real-world examples of pulleys. Cool "Technology in Action" spreads give readers an inside look at how pulleys work. This accessible book is the perfect introduction to this simple machine and is sure to encourage an interest in STEM.
How does a pulley work? What is it? Colorful diagrams and fun-to-do experiments help you explore the many ways this simple machine can help make work easier and faster.
Pulleys help make up some of the most complicated machinery, from car engines to cranes. See up-close the different pulleys that help us move things and get us moving. Kids will love this wonderful look at pulleys, especially the fun with pulleys section.
