Exploring the Earth's Magnetic Field: #1 Playing with Magnetism
Topic: Magnetism
Grade Level: K-4
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students will identify items that are attracted to magnets, experiment with an invisible force and learn about polarity.
Exploring the Earth's Magnetic Field: #10 A Simple Magnetometer
Topic: Magnetism
Grade Level: 5-8
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students will create a magnetometer to monitor changes in the Earth's magnetic field. With this magnetometer they will discover properties of oscillation -- the period and amplitude.
Exploring the Earth's Magnetic Field: #12 What is an Oscillation Period?
Topic: Magnetism
Grade Level: 9-12
Body: Earth
Mission: Earth Science (Earth)
Short Description: Although the mirror sensor card has no pendular motion, it does oscillate from side to side in the horizontal plane. This motion can be studied by students to learn about oscillations in the horizontal plane, as opposed to the pendular oscillation in the vertical plane. Note also that perpendicular forces do not affect each other so although gravity is pulling on the magnet, this force does not disturb the horizontal motion.
Exploring the Earth's Magnetic Field: #13 What is an Oscillation Amplitude?
Topic: Magnetism
Grade Level: 9-12
Body: Earth
Mission: Earth Science (Earth)
Short Description: Although the mirror sensor card has no pendular motion, it does oscillate from side to side. This motion can be studied by students to learn about torsional oscillation in the horizontal plane, as opposed to the pendular oscillation in the vertical plane.
Exploring the Earth's Magnetic Field: #14 The Mathematics of the Simple Oscillator
Topic: Math
Grade Level: 9-12
Body: Earth
Mission: Earth Science (Earth)
Short Description: This lesson is for the calculus or honors physics student. The mathematics of the "simple magnetometer" are further explored to see how the systems of it work.
Exploring the Earth's Magnetic Field: #15 The Inverse-Cube Law of Magnetic Forces
Topic: Magnetism
Grade Level: 9-12
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students use their "simple magnetometer" to measure the deflection of the magnetometer spot and by plotting the data, discover that magnetism follows an inverse-cube law of change.
Exploring the Earth's Magnetic Field: #16 Magnetic Storms from the Ground
Topic: Magnetism
Grade Level: 9-12
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students will plot changes in Earth's magnetism, and identify the regions where magnetic storms are the most intense.
Exploring the Earth's Magnetic Field: #17 Investigating Magnetic Storms
Topic: Magnetism
Grade Level: 9-12
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students will identify how frequently magnetic storms of different severities occur during the year and during the solar sunspot cycle.
Exploring the Earth's Magnetic Field: #18 Magnetic Storms and Solar Activity
Topic: Magnetism
Grade Level: 5-8
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students discuss whether solar activity has any impact on the frequency of magnetic storms.
Exploring the Earth's Magnetic Field: #19 Magnetic Storms and Aurora
Topic: Magnetism
Grade Level: 5-8
Body: Earth
Mission: Earth Science (Earth)
Short Description: Students will compare the amount of energy dissipated by an aurora in the northern hemisphere, with the record Kp index of magnetic storm severity.
