EL6.2
Investigate the characteristics and applications of static electric charges, conductors, insulators, switches, and electromagnetism.

SI

Indicators for this outcome
(a)

Conduct investigations to determine the attraction and repulsion of electrostatically charged materials and represent the results of those investigations using drawings, sketches, tables, charts, and/or other representations.

(b)

Describe how results of similar and repeated investigations into the characteristics of static electric charges (e.g., the rubbing together of different substances) may vary and suggest possible explanations for identified variations.

(c)

Identify natural and man-made applications of static electric charge and discharge (e.g., lightning, photocopiers, laser printers, air filters, and electrostatic paint sprayers).

(d)

Pose questions related to the physical properties of conductors, insulators, simple circuits, and electromagnets (e.g., "How can we determine if an unknown material is a conductor or an insulator?", "How does a switch work in a simple electric circuit?", "What materials work best to create an electromagnet?").

(e)

Make predictions, based on observed patterns of events, related to the physical properties of conductors, insulators, simple circuits, and electromagnets and conduct investigations to test those predictions.

(f)

Identify appropriate tools, instruments, and materials (e.g., bulbs, batteries, and wires) to use when investigating the properties of conductors, insulators, simple circuits, and electromagnets and use those tools and apparatus in a manner that ensures personal safety and the safety of others.

(g)

Test the conductivity of a variety of solids and liquids, following a given set of procedures, to identify which materials are conductors and which are insulators, and draw conclusions about the types of materials that work best as conductors and which work best as insulators.

(h)

Explain the role of switches in electrical circuits.

(i)

Describe the operation of an electromagnet and contrast magnets and electromagnets.

(j)

Plan a set of steps to carry out a fair test of a science-related idea related to electromagnets, such as how to increase the strength of an electromagnet.

(k)

Use evidence gathered through research and observation to answer questions related to the physical properties of conductors, insulators, simple circuits, and electromagnets.

(l)

Describe the operation of common technologies based on properties of static electricity, current electricity, or electromagnetism.

The Power of Electricity
In this program, viewers learn about various ways in which electricity is generated, the different kinds of electricity (alternating and direct), and the importance of electricity in our everyday lives. Computer animations illustrate how a turbine and generator work, as well as the function of transformers. The Hoover Dam is used as a primary example of how flowing water may be harnessed to produce electricity. This program also touches on the importance of energy efficiency, as well as alternatives to using fossil fuels in the area of transportation. Examples include electric cars and trains. The need for reducing consumption of electricity is not directly addressed.

Pearson Saskatchewan Science 6. Student Text
Saskatchewan Science 6 is custom published for Saskatchewan and developed by a team of Saskatchewan teachers. Each unit starts with a list of "Big Ideas" that sets 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 term is provided. All key terms and explanations are also listed in a glossary at the back of the text. First Nations and Métis content, perspectives, and ways of knowing are an integral part of the Saskatchewan science text. Highlights of the activities and achievements of Saskatchewan men and women are provided in the "Ask ..." feature. In each unit, the "Ask ..." feature provides access to the wisdom of a First Nations or Métis Elder or Traditional Knowledge Keeper, who shares an oral story related to the content of that unit.

Understanding Electricity
This video program consists of four segments. Part 1, Tune in to TV, looks at the history of television and how images travel from the camera to the screen. Part 2, Generating Electricity, focuses on the generation and transmission of electricity from power plants to cities and homes. Some of the dangers of electricity are also addressed. In Part 3, Bright Lights, Big Benefits, viewers visit Las Vegas as they consider some of the uses of electricity. They also learn about the role of electricity in improving the lives of heart patients and amputees. Part 4, Energy from the Earth, presents a brief description of electric generators and discusses how geothermal energy may be used to generate electricity.

Transformed. How Everyday Things are Made
Slavin shows the process of how objects are changed from raw materials to the finished products. He uses common items that students are familiar with, such as baseballs. Each two-page spread describes how the object is made by breaking the process down into steps. Illustrations complement the text and show the technology behind the science. Slavin demonstrates the connection between science and technology in making objects. The book includes a table of contents, a glossary, suggestions for further research and an index.
