I learnt that in electrical circuit, the parallel arrangement is brighter than the series arrangement.(textbook). If two negative sides of two batteries is fixed together, the bulb cannot light up. Conserving electricity is easy. We can do it by using energy saving bulbs instead of our normal "filamental" bulbs. I also learnt that in the parallel arrangement, if a bulb fuses, the other bulbs can continue to light up. Most of the conductors of electricity as I have learnt in the textbook, is usually made of metals. But other materials can be conductors of electricity too In my opinion, my theory is that water is an insulator of electricity (textbook).

I learnt that water is an insulator of electricity ( Textbook) .

I learnt how to construct a circuit .

To construct a basic circuit , you will need a bulb , some batteries and some wires .

If batteries are placed facing each mother in a circuit , electricity will not be able to pass through, therefore the bulb in the circuit will not light up.

I learnt that electricity is the set of physical phenomena associated with the presence and flow of electric charge. Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and electrical current.

# data[].attributes.body
I learnt that a simple electric circuit consist of a switch,a light bulb, a battery and wires.

We should also use LED light bulbs instead of florescent light bulbs as LED light bulbs

consume less electricity and also lasts longer.All types of metal can conduct electricity.

Whereas,non-metals like,wood,glass and plastic do not conduct electricity. We should

not touch an electric appliance when our hands are wet.

# data[].attributes.body
i learnt that wind energy can be transformed into electricity.our skin has moisture which allows us to conduct electricity and so we get electric shock

of a light bulb,batteries and wires.

# data[].attributes.body
I learnt that a closed circuit is a circuit that works and a open circuit is a circuit that cannot work. Using charcoals to produce electricity is a bad way as burning charcoals will produce smoke and it will pollute the air. Light bulbs arranged in parallel is brighter than bulbs arranged in series.

# data[].attributes.body
I learnt what makes up an electric circuit and tungsten is not a good

conductor of electricity.Water is also a conductor of electricity so it is dangerous

to stay in a pool when there is lightning.

# data[].attributes.body
I learnt that a circuit is made of wires, batteries and light bulbs. I also learnt that conserving energy is very important to save the world from global warming. I also learnt that different materials can conduct electricity but all of them does not conduct electricity at the same way. I also learnt that water is a pretty good electric conductor.

# data[].attributes.body
I learnt that an electric circuit is only considered a closed circuit when it provides an uninterrupted or endless path for the flow of electric current.I also learnt that water is also a good conductor of electricity.When batteries are placed in parallel all the positive terminals are joined together with a single wire to one part of the circuit, and all the negative terminals are joined with a single wire to the rest of the circuit.

# data[].attributes.body
I learnt that how to use electricity wisely, parts of an

electric circuit and what is it made up of. I learnt the conductors and insulators of electricity. For example water is a conductor of electricity. I learnt that we should conserve electricity by turning off the lights and fans if not in use.

# data[].attributes.body
I learnt that it is the .amps that kill you, not the voltage. I learnt about conductors of electricity. I learnt that water is a conductor of electricity too, and Tungsten is not a conductor of electricity and is being used as filaments of light bulbs solely because of its ability to withstand a very high temperature.

# data[].attributes.body
I learnt that when a circuit does not let electricity to flow through completely,

it is considered as an open circuit.( adapted from textbook)

I learnt that metals are good conductor of electricity but non-metals are not.

Metals are good conductors

of electricity because the electrons are free to move in a
network of metal atom. So because of the "Sea of Electrons", these electrons do
not belong to just one atom but move freely about the metal's network which
makes them great conductors of heat and electricity. (copied from Yahoo! Answers)

I also learnt that cicuits can be put in

parallel or series

# data[].attributes.body
I learnt that electricity is one of the most basic forms of energy.It is composed of two forms,neutrons and electrons.Because of this, electricity is important for our daily routines everyday.There are also materials that are associated with electricity. they are called conductors/non-conductors of electricity e.g(iron,cloth, graphite wood...etc.) I have also learnt that electricity flows better in bulbs with parallel circuits as not only will it be brighter, when one bulb fuses,the others will still remain lit.This is why bulbs with parallel circuits are commonly installed in most households.

# data[].attributes.body
Batteries can be arranged in a parallel or series arrangement

Bulbs can be arranged in a parallel or series arrangement

Electricity can flow only if it is a closed circuit

Metals are conductors of electricity

Non-metals are insulators of electricity

# data[].attributes.body
I learnt the different conducters and insulators of electricity. Eg. wood(conducter), Metal(insulator) and more

I learnt that an electric circuit has to consist of a battery, wire, bulbs, in order for the bulb to light up.

I also learnt that tungsten is a conducter of electricity so that electricity is able to pass through to reach the batteries.

# data[].attributes.body
I learnt that we should use energy saving bulbs to save electricity. I also learnt that a circuit can only consist of wires and batteries only. I learnt that lightning is a natural source of electricity. Our body is a poor conductor of electricity as we also can get electric shocks.(not that our body is NOT a conductor of electricity, but our body is a POOR conductor of heat.) Batteries also has positive and negative poles. There is electric charge if the positive and negative poles comes in contact with each other. Conductors of electricity are:water, metal and graphite. (Research) and insulators of heat are:wood, glass, plastic etc.(textbook)

# data[].attributes.body
I learnt that a closed circuit is considered as a closed circuit

if electric current is able to flow. Metals are good conductors

of electricity while plastic and other materials are poor

conductors of electricity. Water can also conduct electricity.

Bulbs arranged in parallel light up more brightly than bulbs

arranged in series. Tungsten is used in bulbs NOT because

it is a poor conductor of electricity, but because it has a very

very high melting point.

# data[].attributes.body
I learnt that electricity is a form of energy that powers electronical devices. A circuit allows electricity to flow through. A basic circuit is made up of a few basic objects e.g. batteries/ wire/ bulb. Conductors of electricity allow electricity to flow through it easily, especially metals. However, there are other non-metals that allow electricity to flow such as water, carbon ,graphite etc. The light bulb is made up of a metal tip, metal casing, glass casing and a filament. The filament, usually made of tungsten, is actually a poor conductor of electricity that is able to withstand high temperatures.

# data[].attributes.body
I learnt that tungsten is a poor conductor of electricity.

It(tungsten) can withstand about 3000 volts while other

metals could not. Other metals could only withstand

about 1000 volts.

# data[].attributes.body
I learnt that the tungsten is not a good conductor of

electricity. It can light up as when electricity passes through it,

the tungsten heats up and gives off light. It is a good material

to use as its melting point is higher than other materials. All metals

are conductors of electricity but there are other things that conduct electricity like water and graphite.

# data[].attributes.body
I learnt an electric circuit needs a battery and wires, and that tungsten is not a good conductor of electricity. I also learnt that water can conduct electricity. Electricity is running out soon, so we have to save them by switching off electical appliances when they are not in use.

# data[].attributes.body
I learnt:

Batteries have a negative and postive side.

Electricity can come from lightning

If a bulb receives too many volts, it will fuse.

Electricity flows from the negative side of the battery to the psotive side of the battery.

Metal conducts electricity while wood,glass,plastic,paper etc. are insulators of electricity.

# data[].attributes.body
I learnt the different conductors and insulators of electricity

insulator-wood conductor- water. I also learnt that a closed circuit not necessarily need a light bulb and a closed circuit only needs batteries and wires.

Bulbs arranged in a parallel circuit would be brighter then bulbs arranged in a series arrangement

I also learnt that batteries have a negative and positive terminal.

# data[].attributes.body
I learnt that a circuit needs batteries, wires and bulbs to work. Also, with a closed circuit, the light bulb might not light up as the batteries might be put in the wrong way. Plastic, glass are examples of insulators of electricity, while metals are examples of conductors of electricity

# data[].attributes.body
I learnt that water is a conductor of electricity and

not all solid is a conductor of electricity examples like wood and plastic.

When the switch is a close circuit, the bulb will light up while it is a open

circuit, the bulb will not light up . The close circuit allows electric current to

flow. A parallel circuit is brighter then a series circuit.

# data[].attributes.body
I learnt that amperage (amp) is the number of electrons in a circuit

and volts is the pressure (or power) in a circuit. (research)

I also learnt that tungsten is a conductor of

electricity AND heat. (further research)

And I ALSO learnt that skin is NOT a conductor of electricity, but is

still vulnerable to shock. (textbook)

# data[].attributes.body
I learnt that using charcoals to produce electricity is a bad idea but we have

no choice as we have to burn to produce electricity. The smoke will then pollute

the air(textbook). Bulb fuses when the voltage gets too high(Research). Water is a

good conductor of electricity(textbook).

# data[].attributes.body
-->I learnt that we should save electricity as the smoke from burning coals to make electricity pollutes the environment. Also, your electricity bills would be lower (textbook). I learnt that the correct way to say that the bulb exploded is that the bulb fused ( Jing Jing's note). Conductors of electricity are water, metal and graphite (textbook). Insulators of electricity are wood, glass, plastic, etc. (textbook). I also learnt that tungsten was actually not a good conductor of electricity, it can produce light as it can withstand strong heat (Mrs Khan's toondoo).
