The grand challenge for this legacy cycle unit is for students to design a way to help a recycler separate aluminum from steel scrap metal. In previous lessons, they have looked at how magnetism might be utilized. In this lesson, students think about how they might use magnets and how they might confront the problem of turning the magnetic field off. Through the accompanying activity students explore the nature of an electrically induced magnetic field and its applicability to the needed magnet.

This is an activity about electromagnetism and the Sun. First, learners will do a KWL activity using six vocabulary words. Next, they will build an electromagnet and investigate how it works. Finally, learners will relate the workings of their electromagnet to a Solar Dynamics Observatory magnetogram image of the Sun. Per group of learners, this activity requires materials such as a length of insulated wire, alligator clips, a 2-D-battery holder, two D-batteries, and a nail.

This resource provides ways for students to inquire and explore a variety of topics when it comes to producing power, delivering it, conserving it and the ethical, social and environmental considerations that go along with it. As students learn what goes into powering a province, it is hoped that they will also begin a journey of discovering the value of electricity in their lives and the role they can play to use less of it.
This resource was developed to provide teachers with the most up‐to‐date information on electricity in Saskatchewan. As the electrical industry is constantly evolving and regulations and innovations influence new directions, it's important that teachers have current information to share with students.
As much as possible, teachers are forwarded to the SaskPower website as that will have the most current content. Student handouts will be updated annually, but if there is a discrepancy between the printed copy and the website, please defer to the content on saskpower.com.
This resource was developed by SaskPower with input from educators who provided valuable ideas, feedback and expertise.

This lesson introduces students to the fundamental concepts of electricity. This is accomplished by addressing questions such as "How is electricity generated," and "How is it used in every-day life?" The lesson also includes illustrative examples of circuit diagrams to help explain how electricity flows.

Building on concepts taught in the associated lesson, students learn about bioelectricity, electrical circuits and biology as they use deductive and analytical thinking skills in connection with an engineering education. Students interact with a rudimentary electrocardiograph circuit (made by the teacher) and examine the simplicity of the device. They get to see their own cardiac signals and test the device themselves. During the second part of the activity, a series of worksheets, students examine different EKG print-outs and look for irregularities, as is done for heart disease detection.

This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion exchange, discuss and research the "softness" and "hardness" of water, and use the periodic table to identify elements and learn their characteristics. Background information, a glossary and more is included. Materials needed for each student group include a 9-volt battery, two electrodes (e.g. copper strips, or two #2 pencils sharpened at both ends), electrical wire and glass beakers or ceramic saucers. This activity is part of the Aquarius Hands-on Laboratory Activities.

This book offers an introduction to the electromagnetic spectrum using examples of data from a variety of NASA missions and satellite technologies. The 84 problem sets included allow students to explore the concepts of waves, wavelength, frequency, and speed; the Doppler Shift; light; and the energy carried by photons in various bands of the spectrum. Extensive background information is provided which describes the nature of electromagnetic radiation.

Students are presented with a hypothetical scenario that delivers the unit's Grand Challenge Question: To apply an understanding of nanoparticles to treat, detect and protect against skin cancer. Towards finding a solution, they begin the research phase by investigating the first research question: What is electromagnetic energy? Students learn about the electromagnetic spectrum, ultraviolet radiation (including UVA, UVB and UVC rays), photon energy, the relationship between wave frequency and energy (c = λν), as well as about the Earth's ozone-layer protection and that nanoparticles are being used for medical applications. The lecture material also includes information on photo energy and the dual particle/wave model of light. Students complete a problem set to calculate frequency and energy.

In this activity, students construct an analytical spectroscope and analyze the spectrum produced when various substances are heated or excited with electricity. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.

In this activity, students study the range of colors in a visible light spectrum created from either a glass prism or holographic diffraction grating. This activity is in unit 2 of the "Space-Based Astronomy" guide that contains background information, worksheets, assessment activities, extensions, and alignment to national education standards.

In this activity, a Whiffleå¨ ball containing a battery-operated buzzer is twirled in a circle to demonstrate the Doppler effect.åÊ The demonstration is an illustration of how stellar spectra can be used to measure a star's motion relative to Earth along the line of sight. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.

Using a paper and tape device, students experience how atoms and molecules of gas in Earth‰Ûªs atmosphere absorb electromagnetic energy through resonance. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.

In this activity, students demonstrate the relationship between wave frequency and energy in the electromagnetic spectrum by shaking a rope to identify the relationships. This activity is part of Unit 2 in the Space Based Astronomy guide that contains background information, worksheets, assessments, extensions, and standards.

In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with the magnetic field of a permanent magnet and must make the former look like the latter. They discover that looping the current produces the desired effect and find ways to further strengthen the magnetic field.

This is an activity about the properties of electromagnets, which is a crucial underpinning for understanding how magnetic fields are generated in nature, in the surface of the Sun, and in the interior of Earth. Learners will create an electromagnet by letting an electric current flow through a wire to generate a magnetic field, which is then detected using a compass. This activity requires a thin insulated wire, pencil, battery, compass and paper clips. This is Activity 2 of the Magnetism and Electromagnetism teachers guide.

So we ended last episode at the start of the 20th century with special purpose computing devices such as Herman Hollerith’s tabulating machines. But as the scale of human civilization continued to grow as did the demand for more sophisticated and powerful devices. Soon these cabinet-sized electro-mechanical computers would grow into room-sized behemoths that were prone to errors. But is was these computers that would help usher in a new era of computation - electronic computing.

Students learn about current electricity and necessary conditions for the existence of an electric current. Students construct a simple electric circuit and a galvanic cell to help them understand voltage, current and resistance.

The computer will give you a list of chemical symbols and a list of chemical names. Choose the chemical name that each chemical symbol represents. Press the 'Check my answers!' button after you have made your choices.
