  • Is solid water insulator or conductor?
    CONDUCTOR
  • What happen when two objects have zero/neutral charge?
    Two objects with zero net charge do not attract or repel each other.
  • What is the mission of the power source (battery)?
    The power source (battery) creates an electric current flows when the poles are connected through a conductor.
  • Complete the sentence. An object is negatively charged when it contains........ 
    An object is negatively charged when it contains more negative  charges than positive charges. (More electrons than protons)
  • Which part of a circuit conducts energy?
    wires
  • What type of charge has the protons got?
    POSITIVE
  • An object can have _______, ___________ or __________
    An object can have positively charged, negatively charged, or zero net charge.
  • In a simple circuit, there is only one path for current to go and only one load.... TRUE OR FALSE?
    TRUE
  • What are the parts of an atom?
    Protons, neutrons and electrons
  • In a parallel circuit, there is more than one path for current to flow.... TRUE OR FALSE?
    TRUE

    NEGATIVE
  • NAME 5 CONDUCTORS
    Metal, copper, iron, steel, water, aluminium, etc..
  • What type of circuit is it?
    Simple circuit
  • Complete the sentence. An object is positively charged when it contains........ 
    An object is positively  when it contains more positive charges than negative charges. (More protons than electrons)
  • Opposite poles ______ each other.
    attract 
  • It turns the electric current on or off. It is a simple mechanism that opens and closes a circuit.
    Switch
  • All magnets have ______ opposite poles
    Two
  • It's the power source of an electric circuit. It creates an electric current flows when the poles are connected through a conductor.
    Battery
  • NAME 5 INSULATORS
    Plastic, wood, glass, rubber, ceramic, fabric, wool, etc...
  • When do two objects attract?
    Two objects oppositely charged attract each other.
  • What parts has got an electrical circuit?
    Power source, switch, wires and load
  • What type of circuit is it?
    Series circuit
  • Complete the sentence. An object with an equal number of positive and negative charges……..
    An object with an equal number of positive and negative charges has zero net charge. (We also say that the object is neutral).
  • In a series circuit, there is only one path for current to go with three or more loads.
    FALSE. In a series circuit, there is only one path for current to go with two or more loads.
  • Identical poles ______ each other
    Repel
  • It connects all the parts and sets a closed path between the poles of the shower source through which the current flows.
    Wire
  • Neutrons have negative electric charge. True or false?
    False
  • What's a insulator?
    An insulator is a material through which an electric charge cannot move easily.
  • What type of circuit is it?
    Parallel circuit
  • What's elecricity?
    Electricity is the "flow" of electrons.
  • What is a conductor?
    A conductor is a material through which an electric charge can move easily.
  • Is a battery a power source? True or false?
    True
  • Name two magnetic materials
    Iron, steel, cobalt, nickel
  • Complete the sentence. We use electric circuits to transform ............
    We use electric circuits to transform electrical energy into other useful forms of energy: light energy, thermal energy, mechanical energy, sound energy, etc
  • When do two objects repel?
    Two objects with the same charge repel each other.
  • A switch opens or closes a circuit. True or false?
    TRUE
  • It transforms the electrical energy flowing into another form of energy: light, heat, movement, sound, etc.
    Load
  • What part of the atom is not inside the nucleous?
    ELECTRONS
