Fire+and+Cup+Experiment

Fire!!!



Are fires hot or cold?



Fires are REALLY hot!

Fires can heat things up to the point where other objects may burn or even melt.





But what causes a fire to start? There are 4 elements that cause a fire to occur.



1) a heat source, 2) an oxygen source, 3) fuel, and 4) a kindling point.

Fires can be dangerous if your not careful, but they are also very helpful.



When your cold, a fire is a great way to stay warm.



Fire fighters, and before them, used controlled fires to clear away dead brush or plants which helped new plants to grow.



People also use fires for cooking! Sometimes there isn't a stove or oven around and you gotta cook the old fashion way.



Sometimes there isn't a substitute for a good open flame.

Have you ever cooked with an open flame? Well today we are, but first.....

Tomorrow.... we are going to do an experiment using fire!!!



Controlled baby fires though :)





For the first experiment, we are going to see what happens to a flame when we take away one of it's key element; oxygen.

Does anyone have a guess at what will happen to the flame? What about the water surrounding it?

The next experiment involves setting things on fire!!



What will happen when we hold this cup over an open flame? Will it catch on fire? What if there's water in the cup? Or what if we use a water balloon???

Let's not worry about that right now....

Can you guess what we are going to make using an open flame?

I'll give you 3 hints....







When you put this 3 awesome items together you have....



Smores.
