Phil is in a dark place with the Hub Lab in this latest experiment which we don't think you should try at home, as it involves FIRE!
In this Hub Lab we will get to...
1. Understand fire and what is needed for it.
2. Take our understanding and predict how we might extinguish fires.
3. Learn about chemical reactions and their products.
What is fire?
Fires start when a flammable and/or a combustible material with an adequate supply of oxygen is subjected to enough heat. For a fire to exist it requires three elements to be in place Heat, Oxygen and Fuel. This is known as the Fire Triangle.
The triangle shows what you need to ignite and burn a fire. Removing any one of them means that the fire goes out. Without enough heat, a fire cannot start, and it cannot continue. So pouring water on some fires can help.
Without fuel, a fire will stop. Therefore, moving things that can burn away from the fire can help stop the spread. Without enough oxygen (02) , a fire cannot begin, and it cannot continue. So, replacing the oxygen with something else can stop the fire.
Carbon dioxide (CO2) is a gas that humans interact with every day. Sure, you exhale it from your lungs and plants use it to make food. It's heavier than air and we can use it to extinguish certain types of fires.
