Writing

WALT: inform 

Secsess criteria:

• use a range of verbs (evaporate, melt, etc.)
• use a variety of specific vocabulary (matter, solid, liquid, gas)
• add significant detail to describe each part (examples, diagram, giff)
• vary sentence starters

• organise my ideas into at least 5 paragraphs
  
  

DESCRIPTION: Write an explanation about something you have learned about energy. 
Evaluation: I think I did great at this activity and I put a lot of effort into it but I think it would make it even better if I could add a tiny bit more detail on the sumare

Ways that heat travels 

Introduction:

There are three ways that heat travels radiation, convection and conduction. 

Radiation is transferred by waves, convection travels by movement and finally conduction travels by touch. Three of the main ways that heat energy travels.

Radiation:

Radiation is heat that travels in waves. Think of the sun as a light bulb, warm it up until It is really hot then place you hands about 3cm away from it. You should be able to feel the ray of heat from the light bulb. This is called radiation. This is what the sun does to you on a hot day at the beach. This is how you get sun burn. That proves that the suns radiation is very powerful.

Conduction: 

Conduction is another way that heat travels. It travels by touch. This occurs when something is touched against something else. Say that there was a battery and a black wire and a red wire both hooked to a battery. If you tuch the red end with the black end you will get a spark because of the conduction between the positive and the negative.

Convection:

The final way that heat is transferred from one place to another is convection. Convection takes place when heated molecules move from one place to another, taking the heat with them. Convection is common in both the atmosphere as well as in the oceans.

So in this writing I have told you the three main ways that heat energy travels.
