1 FIRE BY KAURI AND DENNON

2 What we want to learn: How fast does fire spread? Can you change the colour of fire? When was fire invented? What is the normal colour of fire? How does fire form? How does fire occur? Is fire one of the key elements?

3 What we already know: Fire is very dangerous Fire is deadly Fire spreads very quickly You can do many tricks with fire Fire can burn you up Fire can kill if played with

4 How Fast Does Fire Spread? It can travel 100 miles in 3 seconds flat Depending on what is being burnt and where its getting burnt. Fire is also faster than a speeding bullet. People describe an experience of driving down the road at 80 or 90 km/h and not being able to keep pace with the fire.

5 Can you change the colour of fire? Yes you can change the colour of fire and its not that hard to do. Red: any Strontium salt like Strontium carbonate, Strontium nitrate, and Strontium sulphate. It's commonly found in road flares so if you have one, gut it. Orange: calcium chloride. It's in laundry bleach but it's too difficult to separate out from there Yellow: Sodium Nitrate Green: Barium salts such as Barium nitrate or Barium chlorate. Chlorate works the best by far. Turquoise: Copper sulphate. It's found in algaecides for pools and ponds and possibly in a high enough concentration to work. Blue: Copper Chloride Purple: Potassium permanganate White: Magnesium Sulphate. It's found in Epsom salts but I haven't gotten it to react very well myself. I've heard plain old magnesium filings works so well, the intensity can damage your eyes so you might want to try that

6 The Steps On How To Change The Colour Of Fire The most important and first step is read all the warnings for this article. If you don't, very bad things could happen. 2 Now determine what colour you want to change the flame to. The options are red, orange, yellow, green, turquoise, blue, purple, and bright white. 3 Now you need to get some of the material required to give you your desired colour. Do note ahead of time that all of these materials are available on eBay or from specialized online retailers. You can search eBay or Google products to find someone that sells them. None of them are terribly expensive. But if there's an easier way to get some, I'll mention it below. Here's the breakdown by colour: 4 Build a campfire and let it burn until there is a decent bed of red embers present. Let the flames die down a little but there should still be some visible. Usually about 1 foot flames with brightly glowing red embers is about right. 5 Carefully add your chosen material directly onto the embers. Add only a small amount at first to test and make sure no unexpected chemical reactions like an explosion occurs. Keep adding more until you see a noticeable change. It may take up to a minute for the effect on the flame to be visible.

7 When Was Fire Invented And What It Was Used For It's disputed. The earliest evidence for the use of fire suggests that it was used in Africa by Homo Erectus as much as 1.5 million years ago. However, some people feel that hearths or scorched circles of stones are the only evidence of fire use, so the only evidence we have shows that fire was definitely being used somewhere between 200,000 and 500,000 years ago. The earliest (and still very popular) use of fire is for cooking food. It can also be used to create light at night time, so you can more easily see what's going on in your cave.

8 What is the normal colour of fire Orangey red but the other colours are red, green, orange, turquoise, purple, yellow, pink, blue and white

9 How does fire form Typically, fire comes from a chemical reaction between oxygen in the atmosphere and some sort of fuel (wood or gasoline, for example). Of course, wood and gasoline don't spontaneously catch on fire just because they're surrounded by oxygen. For the combustion reaction to happen, you have to heat the fuel to its ignition temperature.

10 How does fire occur Fire is one of the most destructive accidents that people usually have. Fire will cause a lot of danger for the human life. A lot of people will lose their family and also their prosperity. Unfortunately, a lot of fire is caused by the human error. This fact teaches us to be more aware in doing all of our activities and protecting our family. So there will be no more fire to surround you. There is some common human error that causes fire. For example, some people do not carefully use fire in their home, store and other public places. Fire is also possible happened because of the house hold utensils that is burned or stunned by fire. The burning of fuel oil such as gasoline, kerosene, gas and diesel also can be caused of fire. Fire also can happen because the occurrence of short-circuit the flow of electricity in your home or store electricity system. In particular region, the natural factors are also holding a prominent role, for example hot weather and winds that cause huge forest fires.

11 Is fire one of the key elements Yes it is. Fire water wind and earth are the four main elements that shape our world today.
