Investigate characteristics of simple machines, including levers, wheels and axles, pulleys, inclined planes, screws, and wedges, for moving and lifting loads.


Indicators for this outcome

Pose and refine testable questions about the operation of simple machines.


Demonstrate how simple machines (e.g., hammer, screwdriver, pliers, bottle opener, ramp, splitting wedges, and scissors) act to reduce effort, increase the distance a load moves, and/or change the direction of an applied force.


Select and safely use tools and materials in a manner that ensures personal safety and the safety of others when investigating the characteristics of simple machines.


Design and carry out an experiment to compare the force needed to lift a load manually with that required to lift it using various simple machines.


Demonstrate how the position of the fulcrum, the load, and the applied force differs for each of the three classes of levers.


Determine the relationship between the applied force and the distance the load is moved for each class of lever.


Compare the operation of wheel and axle mechanisms (e.g., Ferris wheel, bicycle wheel, rolling pin, in-line skate, windmill, and door knob) with the operation of levers.


Determine the effectiveness of wheel and axle mechanisms (e.g., screwdrivers, wheels, doorknobs, and gear systems) of various diameters, rotational speeds, and rotational directions for accomplishing specific tasks.


Investigate the relationship between the amount of applied force and the distance that the load is moved in single and multiple pulley systems, including determining the mechanical advantage of the system.


Explain the operating principles of an inclined plane, such as a ramp or ladder, with reference to the applied load and the distance that the load is moved.


Design and construct a prototype of a simple machine which is meant to accomplish a student-identified task.


Evaluate the efficiency and effectiveness of a prototype of a simple machine using student-identified criteria, and refine the prototype based on data.


Create a representation of the characteristics and operating principles of each type of simple machine.


Recognize that scientific processes and ideas help explain how and why simple machines operate.


Pose new questions to investigate about the characteristics of simple machines.

Everyday Simple Machines
This video examines simple machines. Six types of simple machines are explored. Examples demonstrate how simple machines make our lives easier: inclined planes, wedges, screws, wheels and axles and pulleys.

The Chinese Thought of It: Amazing Inventions and Innovations
The Chinese people used the resources around them to improve their lives. Travel and trade were facilitated with the development of the paddleboat. The dragon-spine water lift allowed the Chinese to move water from the river to a field or reservoir. The Chinese were among the first to invent processes for working with metal. Health and healing practices, such as inoculations, are believed to be used as early as the 10th century CE. The book includes photographs, illustrations, a table of con...

Pearson Saskatchewan Science 5. Student Edition
Pearson Saskatchewan Science 5 is custom published for Saskatchewan and developed by a team of Saskatchewan teachers. Each unit starts with a list of "Big Ideas" that set the focus for the unit. A Big Idea then provides the title for each section in the unit. Throughout the unit, opportunities are provided for students to work together, communicate ideas, perform experiments and carry out library and Internet research. Key vocabulary is bolded throughout the unit and an explanation of each te...
