2.The bulb consists of the filament, metal casing ,metal tip and glass bulb which has no air.
3.When the Filament gets too hot, it emits light and it is made of tungsten.

# data[].attributes.body

# data[].attributes.body
I learnt that electrical systems may comprise of two or more electrical circuits, which are carefully connected so that the electrical system functions properly.

It also has four parts, filament, metal casing, metal tip and glass bulb.

3 Things I Learnt
1 The glass bulb does not contain any air so it protects the filament from potential damages.
2 Bulbs will only light up if the wire is connected from one pole to another.
3 A bulb will light up if the wire is connected with only the the metal casing and the metal tip.

# data[].attributes.body
I learnt that:
1. The bulb has different crucial parts (filament, metal casing/tip, glass bulb, etc)
2. There is a difference when a electrical circuit is opened or closed (the switch is one example).
3. There are chemicals inside a battery. (I wonder what they are. Uranium?)
You may use any but please do not copy.
Bonus: Tungsten is the element that can withstand more heat than any other elements. In second place, ceramic.

# things I learned after watching the video
1) I learnt that the filament inside the Light bulb is made out tungsten.
2) The glass casing helps the light bulb by making it not overheat and it will explode.
3) The electrical system is made out of  a switch, Wires, A light bulb and a battery

# data[].attributes.body
3 things I learnt about electrical systems :
1] I learnt that the filament glows and emits light when having electricity.
2] I learnt that the glass contains no air to protect the bulb from being damaged or exploding.
3] The tungsten material: A special strong piece of metal which can stand against a lot of heat.This amazing feature of this strong material helps the filament against melting and thus, the filament will emit a lot of light. The tungsten is the right choice for the material of the filament due to its astonishing characteristic/s

Hope I learn more!:D:D:D

3 things I learnt today:
1. When there is no gap in a circuit,it is called a closed circuit. When there is a gap in a circuit, it is called a open circuit.

2. I learnt that the light bulb is made up of different parts such as the filament, glass bulb, metal tip, metal casing.

3.The filament of the light bulb is made up of a special material called the tungsten.

3 Things I learnt today

The glass bulb has no air in it so that it can protect the filament which is made of a material called tungsten.

It is important to have a closed circuit if you want to light up a bulb in a simple set-up which includes a battery, two wires and a light bulb.

Last but not least, I learnt that there are chemicals in the battery.( no wonder that day a battery spoilt and leaked some brownish stuff out)

I had fun learning this and i hope to do more of flipped classroom.

# data[].attributes.body
1. I learnt that the filament is made of tungsten which is can conduct heat without melting easily.
2. I learnt that if you want to light up the bulb,  the wire must connected to the metal tip and then out through the metal casing .
3.There is almost NO air in the bulb

# data[].attributes.body
(1)The light bulb is more dangerous than it seems because if you on it for too long it would explode.(Not that dangerous because it takes a really long time until it explodes)

(2)The filament that is made of tungsten(a metal that conducts heat well without melting easily) actually lights up because of the heat from the  electricity(I didn't know that!)

(3) I finally understand how the light switches actually work ~ On: The electricity will be able to flow smoothly that enables the whole circuit to work( ~  ~Off: The electricity will not be able to flow throughout the circuit that means the whole circuit  "experiment"( I don't know what you call it)will not work ~

This is seriously what I learnt so  ~ (just to tell you that I did not take it from anyone)---------:)

# data[].attributes.body
3 things I learnt:
* The glass bulb is sort of vacuumed so there is almost no air in it so it protects the filament like a shield. ( I had no idea! )
* There must not be a gap in the electrical circuit else, the electrical charges will not be able to flow through it.
* The positive(+), negative(-)  sides of the battery,metal tip and metal casing are crucial parts of a simple experiment of electrical circuits that have to be connected with the wires.

By the way, I did not copy from anyone. You may use them but in your own way.

# data[].attributes.body
The three things i learnt are ..................
1. The glass bulb contains no air in it so that it can stop /prevent from any damage  happening
2. The filament in the light bulb is made of a material callled tungsten.
3 . The bulb will light up if one wire is connected to the metal casing and the other in the metal tip.(Very Important!)

I learnt that...
~the glass bulb contains no air so that it can protect the filament from potential damage.
~it is important to connect the wire to both the metal casing and the metal tip. If the metal casing or the metal tip is not connected, the bulb will not light up
~the filament is made of a special type of metal called "tungsten" and it can withstand a lot of heat which lights up the bulb.
