Association | Control group | Experimental group |
---|---|---|
ELECTRIC CURRENT–Light/Lighting | The ELECTRIC CURRENT allows light in my house | I have light in my room because the ELECTRIC CURRENT circulates in the electrical circuit |
ELECTRIC CURRENT–Electrical plugs | The ELECTRIC CURRENT that reaches the electrical plugs allows me to charge my phone | N.A |
ELECTRIC CURRENT–Energy | Wind energy can generate ELECTRIC CURRENT | ELECTRIC CURRENT can be produced from solar energy |
VOLTAGE–Light/Lighting | The high VOLTAGE gives great illumination | N.A |
ELECTRIC CURRENT–Lamp | The ELECTRIC CURRENT circulates, and the lamp lights up | The lamp lights up when the ELECTRIC CURRENT passes through the electrical circuit |
ELECTRIC CURRENT–Electricity | Electricity is the ELECTRIC CURRENT of a closed circuit | Electricity is the ELECTRIC CURRENT that is due to the movement of the electrons in the circuit |
ELECTRIC CURRENT–Electrical shock | You get a shock from the ELECTRIC CURRENT | High ELECTRIC CURRENT can give a shock |
ELECTRIC CURRENT–Home appliances | The ELECTRIC CURRENT is for the iron and I can iron | The refrigerator needs ELECTRIC CURRENT to operate |
VOLTAGE–Home appliances | My dryer is plugged in and has a high VOLTAGE | N.A |
BATTERY–Energy | BATTERY energy is consumed for my tablet to work | N.A |
ELECTRIC CURRENT–Electrical circuit | The ELECTRIC CURRENT circulates in the ELECTRICAL CIRCUIT | The electrical circuit is the path of the ELECTRIC CURRENT |
VOLTAGE–Electrical circuit | The electrical circuit has a VOLTAGE | The battery in the electrical circuit creates a VOLTAGE |
BATTERY–Positive | The BATTERY has a positive pole and a negative pole | The BATTERY poles are positive and negative |
BATTERY–Power supply | The BATTERY is the power supply of the circuit | The BATTERY can be a power supply |
ELECTRIC CURRENT–Wires/cables | The ELECTRIC CURRENT passes through electrical wires and lamps | Electrical wires allow the passage of ELECTRIC CURRENT |
ELECTRIC CURRENT–BATTERY | The BATTERY is one of the elements of an electrical circuit through which the ELECTRIC CURRENT passes | The ELECTRICAL CIRCUIT has a BATTERY that provides electric current |
RESISTANCE–Stop | RESISTANCE is for electricity to stop | N.A |
ELECTRIC CURRENT–Ammeter | N.A | To measure the intensity of the ELECTRIC CURRENT in the electrical circuit I use the ammeter |
ELECTRIC CURRENT–Electrons | N.A | The ELECTRIC CURRENT is due to the flow of electrons |
BATTERY–Negative | N.A | The BATTERY has a negative pole |
VOLTAGE–Volt | N.A | The VOLTAGE unit is the volt |
VOLTAGE–Voltmeter | N.A | The voltmeter measures the circuit VOLTAGE |
RESISTANCE–Ohm | N.A | Ohm is the name of the one who invented the law and is the unit of RESISTANCE |
ELECTRIC CURRENT–Ampere | N.A | ELECTRIC CURRENT is measured in amperes |
VOLTAGE–Electrons | N.A | The electrons remain in the circuit and are oriented because of the VOLTAGE |
VOLTAGE–ELECTRIC CURRENT | N.A | The VOLTAGE is related to the generator of the electrical circuit, through which the ELECTRIC CURRENT passes |
BATTERY–Lamp | N.A | To light the lamp, I have to have a BATTERY |
RESISTANCE–BATTERY | N.A | RESISTANCE can be a component of the circuit that is connected to a BATTERY |
RESISTANCE–Light/Lighting | N.A | The high electrical RESISTANCE means that there is less current flow, and the brightness of the lamp is lower |
VOLTAGE–BATTERY | N.A | The BATTERY has negative and positive poles that relate to the VOLTAGE |
