Game+plan+Outline


 * Demonstration Outline:**

For my demonstration I would first explain what my experiment was called and capture their attention with a catchy phrase or something. Then while pouring the soap onto the gas funnel, I would explain that this experiment could be completed with basic house hold items such as soap and water, a pop bottle etc. Next I would clarify that the gas is rising, and getting captured, because the gas is less dense then air. After I think the snake chain is a tall enough length I will add a few droplets of water and make it bow, and relate that adding the water increases the density and hence making it move. I will wet my hands in just plain water and describe that by wetting my hands I am preventing the bubbles from popping, and even more interesting is protecting myself from getting burnt. I will then demonstrate the combustion of the ( methane) gas while translating the point that chemically this experiment is exothermic which means produces a lot of energy. The important thing to mention is the chemical components of how methane will react with oxygen to produce carbon dioxide and water, like many combustion reactions. Nearing the end of my presentation now, I will ask for volunteers who want to try this harmless, but awesome^_^ blaze of bubbles, yet before anyone tries I will state they must be respectable so no one gets hurt, and state that if there is any arm hair they will miss they shouldn't do the flaming. If there is still some time i will allow some questions. It would go something like below, however It should be more technical and chemical for the reason for this is to teach people while Burning stuff :D it should be fun for everyone because how often can you say you are allowed to set stuff on fire at school?

[Have bowl of water already set up]

[Setting up mechanism begin speaking]

Hello class, my name is Jessica Szabo! Do you like bubbles or burning things? well then do I have a great presentation for you. My experiment is called the methane mamba! Today we will delve into the amazing art of snake charming! I know what you are thinking, I couldn't possibly have any live snakes to tame, and although this is the case we can create our own snakes out of some soapy water and methane gas.

[Indicate to the mechanism] [Pour water and measure soap into beaker]

In a few moments i will turn on the gas and allow the bubbles to brew it is important that we have the right density of bubbles so the snake will grow to its highest potential.

[Turn on gas] [Pour solution in] [Talk and let the snake rise] Methane gas is trapped in the bubbles coming up from the soapy solution and will continue to rise until disturbed. One of the cool things that you can do with this methane snake is by adding droplets of water to a specific spot you can make the snake move. [Take droplets with eye dropper from the bowl of water] This movement is because the water increases the density of the bubbles causing it to bow. [Wet hands] I am wetting my hands to protect the bubbles from breaking as I scoop up a portion of the snake [scoop up some. if it floats up high leave a lone grab a new batch with both hands] Now for the exciting stuff. I will ask my trusted associate who has a lit splint to come here and set my bubble stack ablaze.

Fwoom! Woo! Wasn’t that cool? Want to see it again?

[Repeat steps to burn while talking] The combustion of Methane is a very exothermic reaction producing oodles of energy, with the total enthalpy change being -891 kJ. In the Industrial world, heating companies utilize this type of reaction (minus the bubbles) and harness the energy given off, to heat homes, fuel stoves etc.

[burn it again] Fwoom! Does any one want to try this experiment? I must caution you that if you have some arm hair that you will miss then this is not the fun-filled experiment for you!

However if that side-affect is not an issue with you then I will take some volunteers. Raise your hand if you want to try.

Before you do this you must wet your hands and wrists to prevent bubbles from breaking when you scoop it and protect you from getting burnt. You see, When the flame is set, it will evaporate the water on your hands leaving you unscathed. Please be respectable when doing this experiment as you could easily hurt someone or yourself if done wrong or if you fool around.

[Depending on time pick a few volunteers]

Does anyone have any questions? [Answer a few questions if time. and hopefully have good answers]
