BELLWORK What are some common uses for magnets? Why are they important? Use complete sentences. At least two sentence.

MAGNETS AND ELECTRICITY

NEXT GENERATION SCIENCE STANDARDS:  MS-PS2-3. Ask questions about data to determine the factors that affect the strength of electric and magnetic forces.

OBJECTIVES Content Objectives:  Identify some properties of magnets.  Identify the causes of magnetism  Identify types of magnets  Build an electromagnetic device that produces a magnetic field from an electric current. Language Objectives:  Define magnets, magnetic force, magnetic poles, and magnetic field in your science dictionary.  Read a subtopic of a chapter and summarize important information and present their information.  Complete a quick lab on electromagnetic and answer each question using complete sentences.

VOCABULARY:  Magnet: any material that attracts iron or objects made of iron.  Magnetic force: when you bring two magnets together, they exert a push or a pull on each other.  Magnetic poles: two magnets can push each other apart because of their ends.  Magnetic field: the area surrounding a magnet where magnetic forces can be detected.

WHAT ARE SOME PROPERTIES OF MAGNETS?  Many magnets are made of iron, nickel, cobalt, or mixtures of these metals.  Magnetic force is one of the only three forces in nature that can act at a distance.  Electrostatic force and gravity are also forces in nature.  Magnetic force results from spinning electric charges in magnets.  The force can either push the magnets apart or pull them together.

WHAT ARE SOME PROPERTIES OF MAGNETS?  Every magnet has a north pole and a south pole.  If you place the north poles of two magnets together, they will repel, or push away.  If you place the north pole and south pole of two magnets near each other, they will attract, or come together.  A magnet’s magnetic field is strongest near its poles.  The greater the distance from the poles, the weaker the magnetic field.

EVERY DAY MAGNETS Using a blank piece of paper, create something similar like this and paste it into your notebook. Be creative.

EVERY DAY MAGNETS Cut the pictures and its descriptions and paste it inside the magnet template.

EVERYDAY MAGNETS The inside should look like this.

WHAT CAUSES MAGNETISM?  As an electron moves in an atom, it makes a magnetic field.  The electron will then have a north and a south magnetic pole.

WHAT ARE SOME TYPES OF MAGNETS?  Ferromagnetic: a material that can be turned into a magnet  Electromagnet: an iron core wrapped with electrical wire. When an electric current is in the wire, a magnetic field forms.

HOW IS EARTH LIKE A GIANT MAGNET?  Earth has a magnetic field. Earth also has a north magnetic pole and a south magnetic pole.

HOW IS EARTH LIKE A GIANT MAGNET? Scientists now think that Earth’s inner structure produces its magnetic field. Earth’s inner core is made of solid metals. Earth’s outer core is made of liquid iron and nickel, which are ferromagnetic. As Earth rotates, the liquid outer core moves. Charged particles, including electrons, move in the liquid and form a magnetic field. The constant rotation keeps Earth magnetized.

EVERYONE SHOULD HAVE THIS PASTED IN THEIR NOTEBOOK

PRESENTATION:  Each group will be assigned a subtopic of the chapter.  Each group will be responsible for reading their assigned topic and summarize it.  Group Twitter:  Group IG:  Group Skype:  Group YouTube:  Group Tumblr:  Group Facebook:
