Because of the different densities. The density of wood is less than water while the density of a penny is greater than water.

because the pieces that make up the wood are spaced out are the reasons it can stay afloat for a while no matter how large it is but when it does stay in the water for a long time the start to become more close together and when that happends they sink.
Wood contain C, O, H, etc.
No mammals eat logs. However, beavers and porcupines chew on logs to eat the bark and soft fibers between the bark and the wood. Mammals cannot break down the cellulose of wood.
Green logs are used because logs of green wood absorb oxides and other volatile impurities effectively.
a cord of wood is the amount of wood in a stack of 48-inch logs (or cut logs equaling 48 inches) that is 4 feet high and 8 feet wide
Most logs float because the density is less than that of water . (One cubic centimeter of wood weighs (has less mass) less that one cubic centimeter of water (or liquid in which it is placed). However given a LONG time is water, logs can become "waterlogged", soaked through with water and their density becomes greater that of water and they sink.
