SCIENCE GRADE THREE – ELECTRICITY AND MAGNETISM Electricity used to make a magnet Charges Magnetism is used to produce Electricity Electricity and Magnetism Energy Force Fields Conductors Attraction Insulators Vocabulary: All K-2 process vocabulary plus: Data table Forceps Graduated cylinder Attract Battery Circuit Conductor Insulator Magnetism Repel Essential Understandings: There are two types of charges, positive and negative. Negative charges move from one thing to another Electricity is used to provide energy for many different things in our world Wires are used to transfer electricity from one object to another. Conductors transfer electricity, insulators are poor conductors of electric current Magnets are useful because they are attractive to certain objects Magnets and electricity have an invisible force field around them Electricity can produce magnetism, and magnetism can produce electricity
