 Static electricity is what makes:  clothes stick together when they come out of a dryer  gives you a shock with you touch a metal doorknob.

 Electric charges allow an object to exert an electric force on another object without touching it.  The space around a particle where an electric charge can exert this force is called an electric field.  The strength of the field is greater near the particle and weaker farther away.

 All protons have a positive charge (+), and all electrons have a negative charge (-).  usually, atoms have an equal number of protons and electrons, so their charges balance each other, and the charge of the atom is neutral.

 Particles with the same type of charge (positive or negative ) have like charges, and particles with different charges have unlike charges.  Particles with like charges repel each other (push away)

 Particles with unlike charges attract each other, or pull toward each other.

 A static charge is a buildup of electric charge caused by particles with the same charge.  A material develops a static charge when it contains more of one type of charged particles than another.

 Electrons can move from one atom to another.  The movement of electrons through a material is called conduction.

 If electrons move from one atom to another.  The atom they move to develops a negative charge.  The atom they move away from develops a positive charge.

 Magnet’s work the same way:  Like charges repel each other  Unlike charges attract one another  Materials are magnetic based on how their atoms are arranged

1. Like Charges? 2. Unlike Charges? 3. Static Electricity is caused by the movement of: 4. Charge of Protons: 5. Charge of Electrons: 6. Charge of Neutrons: 7. Movement of electrons by physically touching something: 8. The charge around a magnet: 9. Magnets are stronger: (closer together, far away) 10. Can magnets become demagnetized?
