The “stuff” in the world can be roughly divided into…..
If you take all the stuff in the world, you know that there are many different types
1Matter “stuff ”
2Energy
“is what makes the “stuff ” moves.

Matter is the stuff around you. Matter is everything around you. Matter is anything made of atoms and molecules. Matter is anything that has a '''mass, weight, volume, or takes up space. Matter makes up everything from the mountains to the oceans to your fingernail and brain.
Matter = “stuff” around the world.

Electromagnetism
The term "magnetic effect of current" means that "a current flowing in a wire produces a magnetic field around it".
The magnetic effect of current was discovered by Oersted in 1820. He concluded that a current flowing in a wire always gives rise to a magnetic field round it. The magnetic effect of current is called electromagnetism which means that electricity produces magnetism.
Guiding Question:How can you create a magnetic characteristic from a non-magnet material?

Conductivity is the measure of the ease at which an electric charge or heat can pass through a material.
Electrical conductivity tells us how well a material will allow electricity to travel through it. Many people think of copper wires as something that has great electrical conductivity.
Thermal Conductors = a material that allows energy in the form of heat, to be transferred within the material, without any movement of the material itself.

Conductors
Electrical and thermal conductivity are closely related. For the most part good electrical conductors are also good thermal conductors.
![Page 24: Matter and energy ppt](https://reader035.vdocuments.us/reader035/viewer/2022081506/558e5a701a28abfc388b45be/html5/thumbnails/24.jpg)
Conductors
Different Types of Conductors(1) Metals are traditional conducting materials. You see them around the house all of the time. It's a metal wire or one of the metal prongs in an electric plug. There are a lot of free electrons in metallic conductors. Free electrons are electrons that are not being held in atoms, and so, can move easily. Some of the best metallic conductors are copper (Cu), silver (Ag), and gold (Au).
There are some conductors that are not metals. Carbon is the best example.
A solution such as saltwater has a lot of free ions floating around. Those ions (charged atoms) can flow easily, and ionic solutions are very good conductors. One of the reasons you need to get out of the water if there is lightning around, is that water normally contains dissolved ions, and if lightning hits the liquid (solution), it might conduct electricity long distances and electrocute you.

Heat Conductors
Heat passes through some materials easily and these materials are called thermal conductors.
Heat loves to travel and will travel from a warmer material to a colder material. The heat will only travel from hot things to colder things and never the other way around.
![Page 27: Matter and energy ppt](https://reader035.vdocuments.us/reader035/viewer/2022081506/558e5a701a28abfc388b45be/html5/thumbnails/27.jpg)
Electrical Insulator
Handling electricity can have very dangerous consequences, so it is necessary to insulate it from the surrounding environment. Therefore, conductors, such as copper wire, are wrapped in insulating material. Insulating material does not readily share electrons.
Insulators are nonconductive materials that do not readily share electrons throughout themselves. Examples of these are most plastics and rubber, wood, glass and many ceramics. In general, many nonmetals are good insulators. There are always some exceptions (graphite fibers), so it is safest to test if a material is a good insulator.
