Overview

Magnetism is a force that causes objects to attract or repel each other. An object's magnetic force is how strong that attraction is. Magnetic fields are the areas where the magnetic force will work. Magnets also have opposite poles, negative and positive. Remember, opposites attract!

The classroom resource provides a slide show that will introduce magnets, magnetic fields, and magnetic forces. This resource can provide background information for students before they create their own models and conduct their own investigations. There is also a short test that can be used to assess students' understanding.

SC15.3.3

Explore objects that can be manipulated in order to determine cause-and-effect relationships (e.g., distance between objects affecting strength of a force, orientation of magnets affecting direction of a magnetic force) of electric interactions between two objects not in contact with one another (e.g., force on hair from an electrically charged balloon, electrical forces between a charged rod and pieces of paper) or magnetic interactions between two objects not in contact with one another (e.g., force between two permanent magnets or between an electromagnet and steel paperclips, force exerted by one magnet versus the force exerted by two magnets).

Knowledge

Students know:
  • The size of the force can affect the electrical and magnetic interaction of two objects not in contact with one another.
  • The orientation of magnets can affect the magnetic interaction of two objects not in contact with one another.
  • The repulsion or attraction of magnets can affect the magnetic interaction of two objects not in contact with one another.
  • The presence of a magnet and the force the magnet exerts on other objects affects the magnetic force of two objects not in contact with one another.
  • The electrical charge of an object can affect the electrical force of two objects not in contact with one another.

Skills

Students are able to:
  • Explore electrical interactions between two objects not in contact with one another.
  • Explore magnetic interactions between two objects not in contact with one another.
  • Determine cause-and-effect relationships of electrical interactions between two objects not in contact with one another.
  • Determine cause-and-effect relationships of magnetic interactions not in contact with one another.

Understanding

SC15.3.4

Apply scientific ideas about magnets to solve a problem through an engineering design project (e.g., constructing a latch to keep a door shut, creating a device to keep two moving objects from touching each other such as a maglev system).*

UP:SC15.3.4

Vocabulary

  • Magnet
  • Properties
  • Engineering Design Process (Ask, Imagine, Plan, Create, Improve)
  • Attract
  • Repel
  • Forces

Knowledge

Students know:
  • Magnetic forces between a pair of objects do not require that the objects be in contact with each other.
  • The sizes of the forces in a magnetic situation depend on the properties of the objects, the distances apart, and their orientation relative to each other.

Skills

Students are able to:
  • Define a problem that can be solved with magnets.
  • Apply scientific ideas about magnets.
  • Solve a problem with scientific ideas about magnets through an engineering design project.

Understanding

Students understand that:
  • Scientific discoveries about the natural world, such as magnets, can often lead to new and improved technologies, which are developed through the engineering design process.

SC15.6.11

Develop and use models of Earth’s interior composition to illustrate the resulting magnetic field (e.g., magnetic poles) and to explain its measureable effects (e.g., protection from cosmic radiation).

UP:SC15.6.11

Vocabulary

  • Interior
  • Inner Core
  • Outer Core
  • Mantle
  • Crust
  • Molten
  • Magnetic field
  • Magnetosphere
  • Magnetic poles
  • Particles
  • Solar wind
  • Cosmic radiation
  • Solar radiation
  • Waves

Knowledge

Students know:
  • The Earth's interior consists of rock and metal. It is made up of four main layers:
    1. the inner core: a solid metal core,
    2. the outer core: a liquid molten core,
    3. the mantle: dense and mostly solid rock, and
    4. the crust: thin rock material.
  • The temperature in the core is hotter than the Sun's surface. This intense heat from the inner core causes material in the outer core and mantle to move around.
  • It is possible that the movements of material deep within the Earth generate the Earth's magnetic field, called the magnetosphere.
  • The Earth has a magnetic field with north and south poles. The Earth's magnetic field reaches 36,000 miles into space.
  • The magnetosphere prevents most of the particles from the sun, carried in solar wind, from hitting the Earth.
  • Cosmic radiation, which includes solar radiation, is energy from space transmitted in the form of waves or particles.
  • The Sun and other planets have magnetospheres, but the Earth has the strongest one of all the rocky planets.
  • The Earth's north and south magnetic poles reverse at irregular intervals of hundreds of thousands of years.
  • Conditions inside the magnetosphere can create "space weather" that can affect technological systems and human activities. Technological systems that can be impacted may include the operations of satellites, the orbits of low-altitude Earth orbiting satellites, communication and navigations systems.

Skills

Students are able to:
  • Develop a model of Earth's internal composition and identify the relevant components.
  • Describe the relationships between components of the model.
  • Use observations from the model to provide causal accounts for events and make predictions for events by constructing explanations.

Understanding

Students understand that:
  • The composition of Earth's interior may produce a magnetic field with effects that can be measured.
