EXPLANATION TEXT

Making Paper from Woodchips General statement Woodchipping is a process used to obtain pulp and paper products from forest trees. The woodchipping process begins when the trees are cut down in a selected area of the forest called a coupe. Squence of explanation Next the tops and branches of the trees are cut out and then the logs are taken to the mill. At the mill the bark of the logs is removed and the logs are taken to a chipper which cuts them into small pieces called woodchips. The woodchips are then screened to remove dirt and other impurities. At this stage they are either exported in this form or changed into pulp by chemicals and heat. The pulp is then bleached and the water content is removed. Closing Finally the pulp is rolled out to make paper. Where does rain come from? [statement] Rain always comes from clouds. But where do clouds come from? How does all that water get into the sky? [explanation] Think about your bathroom. There is hot water in your bath. Steam goes up from the hot water. The steam makes small clouds in the bathroom. These warm clouds meet the cold walls and windows, and then we see small drops of water on the walls and windows. [explanation] The world is like your bathroom. The water in the oceans is warm when the sun shines on it. Some of this water goes up into the sky and makes clouds. The wind carries the clouds for hundreds of kilometers. Then the clouds meet cold air in the sky, and we see drops of water. The drops of water are rain. [conclusion] The rain falls and runs into rivers. Rivers run into oceans. And the water from oceans makes clouds and more rain. So water is always moving from oceans to clouds to rain to rivers to oceans. So the rain on your head was on other heads before! The water in your garden was in other gardens in other countries.
