Does the color dye in clear water effect it's temperature?
The dye will not affect the temperature of the water unless you have very small quantities of water. There can be a change of temperature when a solid dissolves but we are unlikely to observe this if there is a small amount of solid compared to the volume of water. If you are using less than a cup of water you may observe a temperature change.
Whether presence of water cause forest fire?
What causes the forest fire is not the presence of water, but rather the absence of it. Water puts out fires and prevents wet items from burning - you cannot hope to burn a wet towel unless the fire is there for long enough that the heat causes all the water in a particular area to evaporate. However when the object is dehydrated and then overheated, or if a spark lands on it, it will burn easily. A drought resulting in many dehydrated branches and leaves would increase the likelihood of a forest fire.

What is a quanitive and qualitive observation?

Qualitive observation is using descriptions and words to describe parts of the experiment. One example is the chemical color change of a gas (what shade of color does it have?)
What can Mercury dental fillings do to you?
The answer from the dental community has been "Not Much". There is no conclusive evidence that the amount of Mercury contained in a dental filling can hurt you. You should know that they are not comprised entirely of Mercury and the substance is referred to as amalgam. There are alternatives to Mercury amalgam fillings and you should ask you dentist if these are available if your concern is that great.
