Everyone loves playing with magnets and iron filings. Here, young scientists first observe and then participate in an activity demonstrating magnetic fields. After completing their observations, they apply this knowledge...

Help your young scientists learn which materials are affected by magnetic fields with an activity that presents the information about different types of materials — diamagnetic, paramagnetic, and ferromagnetic — and their interaction...

How do magnetic fields differ? Allow scholars to see the difference between 2-D and 3-D magnetic fields. They construct models of both and observe how they are similar and different. It is the fifth installment of an 18-part unit.

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...

What better way to understand how an object works than to make one! Learners take what they learned in the previous lessons and construct their own compasses. Using a needle, water, and styrofoam, they build and test compasses and verify...

What do magnetic fields look like? The best way to learn about magnetic fields is to try identifying them for yourself. Scholars will understand the importance of magnetic fields after completing this experiment. The extension activities...

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...

Electrical current going round and round,produces a magnetic field. After a demonstration of the magnetic field surrounding an electrical wire, class members use the provided formula associated with Biot-Savart's Law to calculate the...

Introduce your class to the idea of magnetic fields around electrical wires with an activity that provides the information about the direction of a magnetic field around a wire carrying an electric current.

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.

Here is a very good lesson on magnets, magnetism, and magnitic fields that is chock full of great activities for you to implement with your young scientists. Learners discover the properties of magnets, look at the forces of attraction...

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...

An MRI uses both a magnetic and electricity, so how do the two interact with each other? Class members observe the effects on a charged particle when it is subject to both an electrical and magnetic field. The teacher background...

Students explore how compass and Gauss meter detect a magnetic field. For this physics lesson, students build their own Gauss meter and sensor based on given procedure. They cite real world applications of magnetism.

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.

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...

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...

Fifth graders examine the different types of magnets (bar, horseshoe, disc, ball, etc.) and experiment with the magnets and iron filings to discover the magnetic fields of each type of magnet.

Take charge of your class and provide them with an electrical experience! Individuals investigate the basic principles of electricity and magnetism by creating a model to test electric current and the amount of electricity generated....
