LC: To write an explanation text focusing on cause and effect complex sentences, present tense, formal language and paragraphing.

For your first literacy lesson today, you are going to write the second and third section of your explanation plan.

These sections

- must be written in present tense (is, are, have, has)

- use formal language (known as, made by)

- use paragraphs to organise ideas

- have cause and effect complex sentences

You will be starting these sections under your opening statement from yesterday.

You will need the second and third section of your explanation plan to help you. 

See mine below.

Original text (How are humans able to hear sounds?)

Sound is a type of energy that is made by vibrations and vibration is the word used to describe something that is shaking backwards and forwards really quickly. When any object vibrates, it causes the air around it to move. Humans do not see this happening due to tiny things known as molecules that are doing the vibrating. The molecules bump into each other passing the vibrations through the air which is known as a sound wave.

       Furthermore, if your ears are close to the vibrations, then you hear them clearly, whereas the further a sound wave travels, the weaker it gets and they are harder to hear. Sound waves can travel through anything that can vibrate like metal, water or air. Sound travels faster through water than air and even faster through metals like steel. What the sound travels through is known as a medium. In fact, sound needs a medium to travel through otherwise there is no sound.

New text - teacher (How electricity reaches people's homes)

To start, mains electricity is the type of electrical current that is needed to supply power to people’s homes. This type of electricity is made by resources such as coal, oil and natural gas in places known as power stations.  In a power station, the fuel is burned before large spinning turbines can generate electricity. Once the electricity has been created, it is sent to a machine known as a generator. The generator prepares the electricity to be sent to a transformer through wire cables. As a result of electricity losing some of its energy as it travels through wire cables, the transformer’s task is to boost the electricity to a very high voltage before it leaves the power station. This is because high voltage electricity loses less energy than low voltage electricity.

       When it has been boosted, the extremely high voltage electricity is sent out of the power station. It is carried along cables that are held up in the air by huge metal towers known as pylons. Because pylons are very tall and spaced out over large areas, electricity can be sent over long distances at a great speed. Eventually, the high voltage electricity will arrive at substations which can be located in or near to towns and cities.

Use the scaffold below to help you write the second and third section of your explanation. 

You can change the conjunctions to fit in with your explanation. 

Do not forget to paragraph. Use the colour coding to remind you.

To start, ________________ is __________________________.  

In a ____________, _________________ before _____________. 

Once ________ has been created, it _______________ known as _____________. ______________________________. As a result of __________________________, _____________________. This is because ______________________.

        When __________________, __________________. _____ is carried ___________________ known as _________. Because _____________________________, _______________. Eventually, _______________________________________________________.
