=How does radon get into your house from underground?= =What are the percentages of deaths from radon?= by: Darcy media type="custom" key="3574910" Radon rises through the soil and gets trapped under the building. The trapped gases build up pressure. Air pressure inside homes are usually lower than the pressure in the soil. Therefore, the higher pressure under the building forces gasses through floors and walls and into the buildings. Most of the gas moves through cracks and other openings such as cracks in floors and walls, gaps in suspended floors, openings around pumps and drains, cavities in walls, joints in construction materials, gaps around utility penetrations (pipes and wires), and crawl spaces that open directly into the building.

This is what I did for my project...


 * In a plastic box with small air holes in the bottom, I showed layers of the top layer of the Earth, identifying each layer and explaining which one forms radon. I Created cracks in the layers and then put candles under the plastic box then I lit the candles, after that I blew out the candles which then created smoke and I tested to see if the smoke went through the soil and if so (wich it did), the smoke is in radon which went through. then after that I tested the same way with the candles but instead of feeling if the smoke went through with my hand I used a smoke detector. The smoke detector beeped wich meant that it worked!

=How does cigarette smoke effect plant growth?= media type="custom" key="3568574"

by: Cameron How does cigarette smoke effect plant growth? I had a large cardboard box and eight plants and I had some cigarettes. I put four of the plants in the box put a lit cigarette in the box then let the cigarette burn. Cigarette smoke is a combination of many chemicals, two of which are formaldehyde and hydrogen cyanide. Formaldehyde is used in many household products. Hydrogen cyanide was used as a genocide agent in WWII. My smoked plants didn't show much of a difference from the non-smoke plants. If I had kept on smoking the plants you would have been able to tell a difference between the two. I only had two weeks to smoke my plants but I really only did for seven days, because I smoked them every other day. Resources: [|**quitsmokingsupport**]**,** [|**cancer**]

=Effects on trees with air pollution=

=**By David**= Hello! My name is David and I polluted a tree with three different types of pollution (Febreeze, Fabric Refreshener, and Roach and ant killer). The way that I polluted the tree was by spraying it 4 times a day with the different pollutents. While I polluted the tree, I observed and compared a tree that I didn't pollute from the one that I did pollute.At the end ,my conclusions were that if a tree absorbs too much pollution, it will end up dying.** Don't pollute trees!!!!!!!!!!!!!!!!!!!
