Description:

By the end of this lesson, students will be able to:

Describe the magnetic field produced by current in a straight conductor and in a solenoid.

Use the right-hand-rule to determine the direction of the magnetic field in a current-carrying wire.

Given the force on a charge in a magnetic field, determine the strength of the magnetic field.

Use the right-hand-rule to find the direction of the force on a charge moving through a magnetic field.

Determine the magnitude and direction of the force on a wire carrying current in a magnetic field.

Subject: English Language Arts & Literacy in History/Social Studies, Science, and Technical Subjects

Grade : Grades 11–12 students:

Content Area:  Literacy in Science and Technical Subjects

Strand:  Reading Standards

Domain:  Key Ideas and Details

Standard:  2. Determine the central ideas or conclusions of a text; summarize complex concepts, processes, or information presented in a text by paraphrasing them in simpler but still accurate terms.

Standard:  3. Follow precisely a complex multistep procedure when carrying out experiments, taking measurements, or performing technical tasks; analyze the specific results based on explanations in the text.

Domain:  Integration of Knowledge and Ideas

Standard:  8. Evaluate the hypotheses, data, analysis, and conclusions in a science or technical text, verifying the data when possible and corroborating or challenging conclusions with other sources of information.

 

Technology Standards Addressed – you can find the technology standards on the International Society for Technology in Education (ISTE) Website (http://www.iste.org)

ISTE: National Educational Technology Standards for Students: The Next Generation

Standard : 1. Creativity and Innovation- Students demonstrate creative thinking, construct knowledge, and develop innovative products and processes using technology.

Indicator : Students: a. apply existing knowledge to generate new ideas, products, or processes.

Indicator : Students: c. use models and simulations to explore complex systems and issues.

Indicator : Students: d. identify trends and forecast possibilities.

Standard : 2. Communication and Collaboration- Students use digital media and environments to communicate and work collaboratively, including at a distance, to support individual learning and contribute to the learning of others.

Indicator : Students: d. contribute to project teams to produce original works or solve problems.

Standard : 3. Research and Information Fluency- Students apply digital tools to gather, evaluate, and use information.

Indicator : Students: b. locate, organize, analyze, evaluate, synthesize, and ethically use information from a variety of sources and media.

Indicator : Students: c. evaluate and select information sources and digital tools based on the appropriateness to specific tasks.

Indicator : Students: d. process data and report results.

In this lesson, the students will explore the relationship between magnetic fields, electric current, and the forces applied therein.  The students will discover a pattern that allows for the prediction of motion, current flow, and magnetic field direction.  Using these predictive behaviors, the students will learn and apply the Right-Hand-Rule to motors, generators, and galvanometers alike.

Tutorial

Motors & Magnets

After this lesson you will be able to:

Describe the magnetic field produced by current in a straight conductor and in a solenoid.

Use the right-hand-rule to determine the direction of the magnetic field in a current-carrying wire.

Given the force on a charge in a magnetic field, determine the strength of the magnetic field.

Determine the magnitude and direction of the force on a wire carrying current in a magnetic field.


 

You will, on your own, with your device will explore the relationship between magnetic fields, electric current, and the forces applied therein.  Look for a pattern that allows for the prediction of motion, current flow, and magnetic field direction.  Using these predictive behaviors, you will be able apply the Right-Hand-Rule to motors, generators, and galvanometers alike.

 

You need to take (at minimum) one full page of notes based on the PowerPoint and lesson.

You will watch the short clip on motors and generators.

Take the quick quiz to check for understanding.

Then  proceed to work collaboratively on your own devices to create and edit a slide presentation explaining how to use the Right Hand Rule for a coil of wire and how that applies to motors or generators.

Tomorrow you will finish by previewing the other groups’ presentations and filling out the feedback critique form.
