No GPS allowed! High school scientists continue to explore magnetic fields with a hands-on activity. After mapping the ambient magnetic field in the classroom and completing data analysis, they write about the similarities and...

Young scholars 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...

Introduce your class to magnetic fields with an activity that demonstrates that a compass is affected by the magnetic field of the earth, unless a closer, stronger magnetic field is present. Pupils can use this fact in the...

So you built a magnetometer, now what? High school scientists use their magnetometer made in a previous lesson to map the union of magnetic fields of dipole magnets. They experiment with different alignments and draw conclusions about...

High school scientists build their own magnetometer and use it to map the field surrounding a bar magnet. Excellent background resources is included, as well as a diagram of how to build the magnetometer.

Feel the pull of science! The final installment of this 18-part series is an application of everything learned in the previous high school lessons. Scholars are given a magnetic field map and must propose an arrangement of magnets that...

Clever! Earth science learners construct a model of a planet containing a magnetic core. The planet, Terrabagga, is made out of a paper grocery bag, magnets, a dead D battery, and rubber bands. Pictures of each step of the construction...

Young scholars map the magnetic field of a room (classroom or room at home -- recommend kitchen) at two or more heights. They create a coordinate grid within the room and make a relatively accurate map of the room to super impose the...

Students investigate magnetic evidence that supports the theory of sea floor spreading.

Young scholars 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.

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.

Students explain why compass angles need to be corrected for regional magnetic variation. They observe the difference between magnetic and true north. Each student measures the angle of variation for a town in a different state.

How do spacecraft detect magnetic fields? The fourth installment of a five-part unit has learners develop a device with magnets that allows for the detection of magnetic fields. They use a map of an imaginary planet to try out their...

Learners 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. 

Learners discover that sunspots are the result of intense magnetic forces on the photosphere of the sun by observing images from the SOHO satellite.

Students interpret magnetic field maps, rotate the coordinates to obtain different views, change the coordinate representation, and produce alternate graphical representations.

Students determine that moving charges create a magnetic field. They discover that the speed and direction of motion, the amount of charge, and the deflection angle observed are closely linked. A voltmeter, pendulum, and a constructed...

Students use a magnetometer to determine the orientation of a magnetic field. In this magnetism instructional activity, students build a simulated planet and use a simple magnetometer to determine the orientation of their planet's...

Young scholars create a 3D vector field map of an electric field. In this physics lesson, students measure the voltage inside an aquarium with water. They present their findings and map to class..

Students are introduced to the concepts of latitude and longitude. In groups, they identify the Earth's magnetic field and the disadvantages of using compasses for navigation. They identify the major lines of latitude and longitude on a...

Students work in pairs to construct a simple stereoscope.

Introduce learners to set of complete instructions that describe how to build a magnetometer that works just like the ones professional photographers use to predict auroras. The diagrams are wonderfully descriptive, and the written...

What's the difference between true north and magnetic north? Lesson 9 has your class practicing mapping using a compass and taking the correct declination into account. This lesson is one part of a 10 lesson unit on orienteering....

Students compare and contrast maps of New Haven, Connecticut from today and the past. After taking a field trip, they draw sketches of the types of architecture and discuss how the buildings have changed over time. They read journal...
