I'm 10 years old and I think we should clean air. Clea the mess we started. We should make clean coal plants. That's probably why China is so polluted.

dear bashir from WA. i am jeannette. fish can not breath like mammals (also known as humans) because they have gills. gills help fish breath underwater. fish can not breath like us because they do not have lungs.

Me and brother measured how long does paper airplanes last in the sky. It was kind of an experimant and I thought of it. It was kind of windy. We went out on Dec. 18, 2006. We made the Delta Fighter, and the Nasa Space shuttle. It was made of paper, of course. The Delta Fighter was mine. The Nasa space shuttle was my brother's, Eric. Eric's plane stayed up 2 seconds. Mine stayed up 4 seconds. Merry Christmas from Tiffany and Eric.
