Earth's Magnetic Field Teacher Resources
Find Earth's Magnetic Field educational ideas and activities
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.
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.
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.
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.
This is a stellar lab exercise, but know up-front that special equipment is needed: LabPro or Universal lab interface, LoggerPro data collection software, Vernier magnetic field sensor, a computer, and a Slinky® spring toy. An electrical current is run through the toy, and the technology equipment is used to determine if current and solenoid spacing affect the resulting electric field. This five-page resource has a professional appearance and tremendous experiential value.
Students 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.
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.
High schoolers 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.
