1 To be in radiation balance Earth would have to be warmer by about 12C. Clouds cool the planet by reflecting sunlight back into space, much as they chill a summer's day at the beach.  Clouds warm the Earth by absorbing infrared radiation emitted from the surface and reradiating it back down. The process traps heat like a blanket and slows the rate at which the surface can cool. The blanketing effect warms Earth's surface by some 7C.
Making mold grow on bread is not only a great project for the local science fair, it also teaches the ins-and-outs of keeping your bread fresh.With a bit of moisture, a little heat, and a bit of time, you'll have a furry green sandwich that will impress your classmates and gross out your friends.Ad.aking mold grow on bread is not only a great project for the local science fair, it also teaches the ins-and-outs of keeping your bread fresh.
Â© Contributed by Leanne Guenther. This experiment uses 4 samples to test what conditions mold grow the best in. Depending on the age of the child(ren) you can use only 2 or 3 samples instead of all 4.olds will develop on some of the samples. Molds grow best in warm, dark and moist conditions. In the first sample, the sealed bread should develop mold more slowly than the unsealed bread.
