Paper – useful material
People use paper for writing, printing, wrapping, and many other purposes. Hundreds of years ago people made paper by hand. Today machines produce most paper. First, the wood fibers are soaked in water and creates a soupy mixture. Next, this mixture is spread on a screen and rollers press out water. Once the fibers are dry, they have become a sheet of paper.
Paper is available in a wide variety of weights, colors, textures, and finishes for a multitude of purposes. Everyday writing and printer paper is thin and smooth. Paper used for arts and crafts is thicker and textured. Cardboard is a thick type of paper used to make packaging. Paper used for newspapers is thin and cheap. Recycled paper is made from used paper.
