Earth's Magnetic Field and Magnetosphere
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.
Is the Earth Preparing to Flip?
In this Earth's magnetic poles worksheet, 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.
Magnetic Fields and Forces Homework/Electromagnetic Induction Homework
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.
Exploring Magnetic Fields
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.
Using Magnetotactic Bacteria to Study Natural Selection
Young scholars 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.
TE Activity: Northward Ho!
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.
The Earth and the Compass
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.
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 explore how compass and Gauss meter detect a magnetic field. In this physics instructional activity, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.
Activity: Slinkies and Magnetic Fields
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.
The Interplanetary Magnetic Field (IMF)
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.
Magnetic Field Activities
High schoolers explore the idea of magnetic field through investigations of magnetic fields as produced by various common magnetic materials and direct currents. They study the vector nature of fields, the ubiquity of field sources in the environment, and visualize such fields as 3-dimensional entities.
All phenomena concerning magnets, their field lines and impact on objects are covered. The trivia surrounding field lines and the earth, electric charges, repulsion and attraction is plentiful. The slide show continues after twenty slides of laboratory facts to give twenty more about Earth's magnetic field and the Aurora Borealis. This PowerPoint will be interesting to your learners, and could even be used to support note-taking during individual computer time or homework.
INTERPRETING MAGNETIC FIELD MAPS
Students interpret magnetic field maps, rotate the coordinates to obtain different views, change the coordinate representation, and produce alternate graphical representations.
The Earth's Magnetic Field
Students explain how the earth's magnetic field works and looks. They create their own free-floating compass using the everyday materials. After constructing their compass, they test it and determine north.
Young scholars study the earth in relation to the solar system. In this planetary lesson students complete several investigations into the measurement of the earth and its magnetic field.
Using Magnetotactic Bacteria to Study Natural Selection
Students demonstrate that living organisms may possess incredible adaptations which enable them to survive. They observe bacteria that are able to orient themselves using the Earth's magnetic field and formulate a hypothesis as to how this adaptation improves their chances for survival.
Planetary Magnetic Fields
Students use teacher constructed "planets" and test their magnetic field. They hold the planet hear the compa"equator." Students rotate the planet and observe the effect on the compass. They move the planet above the compass and repeat the experiment.
Magnetic Fields and Bermuda Triangles
Students 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.
The Magnetic Field in a Slinky
Students create a magnetic field. In this physics lesson, students use a metal slinky as a solenoid to explore how the magnetic field is different in various parts of the solenoid. They use their graphing calculator to determine the permeability constant.
