__ Questions: __ In a Paragraph or more tell the class your Interests, favorite subjects, favorite topics in science, least favorite topics in science, and what you Would Like to Learn This Year.

====Hi, my name is Ivonne. I love to play soccer,draw pictures then paint them, and build new things out of stuff that I don't use anymore. My favorite subjects are Math and World Geography. My favorite topics in science are The Three Forms of Water, Physical and Chemical changes, and Weathering. The topics in science that I don't like are The Water Cycle, The Plant Cycle, and Plant Parts because they're all too easy. I would like to learn about chemistry, and how technology works.====

Problem Statement : What factors affect burning?
Flammability Flammability is defined as how easily something will burn cause [|__fire__] or [|__combustion__] . The amount of difficulty required to cause the ignition of a substance is quantified through [|__fire testing__]. globally, a variety of test protocols exist to quantify flammability. The rankings achieved are used in [|__building codes__], insurance requirements, fire codes and other regulations controlling the use of building materials, as well as the storage and handling of highly flammable substances inside and outside of buildings and in surface and air transportation. For instance, changing an [|__occupancy__] by changing the flammability of the contents requires the owner of a [|__building__] to apply for a building permit to make sure that the overall [|__fire protection__] design basis of the facility can take the change into account.

The //Flammable Range// (Explosive Range) is the range of a concentration of a gas or vapor that will burn (or explode) if an ignition source is introduced. Below the explosive or flammable range the mixture is too lean to burn and above the upper explosive or flammable limit the mixture is too rich to burn. The limits are commonly called the "Lower Explosive or Flammable Limit" (LEL/LFL) and the "Upper Explosive or Flammable Limit" (UEL/UFL). The lower and upper explosion concentration limits for some common gases are indicated in the table below. Some of the gases are commonly used as fuel in combustion processes.

Chemical Properties of matter describes its "potential" to undergo some chemical reaction by feature of its composition. What elements, electrons, and bonding are present to give the potential for a chemical change? It’s kind of difficult to define a chemical property without using the word "change". Sooner or Later, you should be able to look at the formula of a compound and state some chemical property. At this time this is a lot difficult to do and you aren’t expected to be able to do it. For example hydrogen has the potential to burn and blow up given the right conditions. This is a chemical property. Metals in general have their chemical property of reacting with an acid. Zinc reacts with hydrochloric acid to make hydrogen gas. This is a chemical property.

Hypothesis

If I burn different objects with different types of matter, then it will affect the time it takes for the fire to burn it.

Variables:
Independent: The type of matter of the object

Dependent: The time it takes to burn the object

Controls


 * The type of fuel of the fire
 * The chemical properties of the object
 * The temperature of the fire
 * The location of the fire
 * How much damage does the fire do
