Driftwood is wood, usually branches from trees, that has fallen into the water and then drifted around for a while before washing up on a beach that may be a long way from where it fell into the water. Driftwood is often polished smooth by the waves and water, and bleached to a dull grey.
Firewood is wood that has been collected just to be burnt as fuel. Firewood is usually cut into small pieces so it can fit inside a fireplace.
A hood is a part of another piece of clothing that goes over your head. Hoods are often seen on cloaks, some jackets or hooded sweaters.
Wood is what the trunks and branches of trees are made from. Trees get thicker as they grow, so when you cut them down you can see rings of colors in the inside of the tree, like in the picture. When you cut a tree lengthways the rings become lines called grain, which you can see in most things made out of wood. Wood is used to make houses, furniture and some toys.
