Students investigate the magnitude of Earth's magnetic field using PASCO. In this physics lesson, students describe the features of the magnetosphere. They explain how atmosphere layers protect the Earth.
If you need a visual demonstration of Earth's magnetic field and how it shields us from solar wind, this will meet your need. Although it is short, it includes a variety of computer animations and footage, and more than one narrator leads us through the footage. Your physical science class will benefit from viewing this video.
Students brainstorm on what they believe causes the Earth's magnetic field. After watching a video, they discuss how the magnetic field is shifting and losing strength. To end the lesson, they work together to test the magnetic field with different types of magnets.
Students design a simple compass. They examine how the Earth's magnetic field has both horizontal and vertical components. They determine how a compass works and work with cardinal directions.
In this Earth's magnetic poles activity, students read about the changes observed in Earth's magnetic field and the possible geomagnetic reversal of the north and south magnetic poles. Students answer 5 questions about the reading and Earth's magnetic poles and polarity.
Students explore the concept that magnets attract and repel items and exert a magnetic field that can vary in strength. They see evidence of the magnetic field of a small magnet. They see that there are forces on earth which cannot be seen.
Your advanced physics class will appreciate this lesson in which they use magnetic field sensors to determine the relationship between the number of turns per meter of a solenoid and the magnetic field produced. The materials for this lesson are costly and ample time is required to prepare for the lesson. It is explained in detail, however, and outstanding resources are included. This is ideal for your stronger science scholars.
Ninth graders discover why aurora's are visible only in some places. In this earth science lesson, 9th graders explain how auroras form. They color and label magnetic field lines diagram.
Students brainstorm background knowledge and any questions they may have about magnetic fields. They investigate the role that William Gilbert had in laying the groundwork for modern experimental science. Students observe magnetic fields by working with iron fillings and bar magnets. They record their observations.
Learners observe bacteria that are able to orient themselves using the Earth's magnetic field.They comprehend the difference between anaerobic and aerobic organisms. Students can tell the difference of the shape of magnetic force field lines around a bar magnet and around the Earth itself.
Middle and high schoolers use the Pythagorean Theorem to complete a table showing with the magnetic field strengths in given cities. They find the average value of the Earth's magnetic field and plot one of the three-dimensional values that make up the magnetic field on a map to observe any patterns.
Students observe magnetic fields and locate the position of "ore deposits" patterns using models and maps.  In this magnetometer lesson students complete a hands on activity and a reading/writing exercise. 
Students design an experiment for NASA's STEREO/IMPACT mission to measure the interplanetary magnetic field. This lesson includes 3 excellent hands-on and critical thinking activities in which students explore magnetism in the solar wind.
Fifth graders construct a water compass to investigate the effects of Earth's magnetic field and other sources of magnetism. They predict, observe and draw conclusions from their investigation.
Learners map magnetic fields of a magnet using a compass and predict where fields cancel each other to create 'Bermuda Triangles'. In this magnetism lesson, students use a compass to map the magnetic field of a magnet. They explain how magnetic fields can combine and cancel each other.
Do you believe in Santa Clause? Or a more practical question might be to ask if you believe in the location of the North Pole. Because of the convection currents in Earth's out core, the magnetic north pole drifts about 55 km per year. As an enrichment when covering Earth's structure, you could assign this as homework and then incorporate a discussion into your class the next day.
Students explore how compass and Gauss meter detect a magnetic field. In this physics lesson, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.
Here are two electromagnetism homework assignments rolled into one. The first eight practice problems deal with the magnetic field and magnetic force exerted by current-carrying wires. The second set of seven problems are specific to electromagnetic induction. The answers for each problem follow immediately after, making these physics worksheets unsuitable to use as assessments. You can, however, add them to your collection of homework choices.
Written for a college physics course, this midterm examination deals with electric and magnetic fields. When taking this test, learners answer multiple choice questions, solve problems, and analyze a variety of attractive diagrams. Because it was designed for a general physics college course, it would also be appropriate to administer to your high school advanced placement physics classes.
In this satellite synchrony worksheet, students use a spreadsheet or Least Common Multiples to solve 4 problems related to the satellite orbits, orbital periods and their synchronicity. Students determine when the satellites launched in space at different distances to the Earth's magnetic field will line up again given their orbital periods.
