Oh dont worry ok, calm down. the presentation part is the easiest. get a poster board, glue, scissors, and nicely colored construction paper, from office depo or staples or something. Do research on google or yahoo or ur preference for “greenhouse effects” this is an easy, broad topic that is good for what u are doing. It’s not that important what you choose, as long as you do the work and research for it.

what do u mean “the matter which i have is perfect”? glue, tape, or make slots with scissors in a background and slide papers into the corners.

Greenhouse result’s led to with the help of the absorption of infrared radiation with the help of molecules interior the ambience that have infrared lively bonds. to be certain that a bond to be infrared lively, that’s going to be polar (notice the full molecule does not could be polar, however the bonds could be). for that reason, the three greatest factors of air (nitrogen, oxygen, and argon) do not make contributions to the greenhouse result. different factors of air, including carbon dioxide, water vapor, and methane, do take in infrared radiation. If it weren’t for this result, a great area of the warmth hitting the earth from the solar does not be trapped with the help of the ambience, and Earth’s frequently occurring temperature would be approximately -60 stages Fahrenheit.

please include your grade level so we can help provide you with acceptable resources
