Paper is one of the simplest, most versatile, most available and least expensive materials known to humankind. Although most commonly used for writing, packaging, and wrapping, it is also perfect for doing science experiments. Humans have used paper or paper-like substances for thousands of years. The word paper comes from the word papyrus, a plant from which the ancient Egyptians produced a material like paper to write upon. Nowadays, wood pulp from trees is the usual source of paper fibres. To make paper, these fibres are mixed with a large amount of water. Small amounts of additives such as glue and clay are mixed in, and water is removed through wire screens. The paper fibres deposited on the screens are dried, smoothed, and cut to give many types, thicknesses, and sizes of paper. In this book, you will learn how to do 100 exciting science experiments with paper. Experiments are organised into these categories: air, balancing, chemistry, electricity and magnetism, flying things, heat, light, motion and inertia, noise- and sound-makers, topology, water, and other experiments. This book is easy enough for children to do but can be enjoyed by other people as well. The experiments in 100 Simple Science Experiments with Paper are fun, easy, and safe to do and can be performed using materials and equipment commonly found around the house. Teachers, parents, and children alike will delight in discovering the many ways in which paper can be used to learn and enjoy science at home and in the classroom. From paper bags to cardboard boxes, from crinkly crepe to thin tissue--pick any kind of paper and write your ticket to science fun! Just add some easy-to-find materials like ping-pong balls and combs, and create a weather vane to learn about air, a paper bridge and birds to demonstrate balance, and a spinning spiral snake to show the power of heat. Go up, up, and away with index-card helicopters. Make a bang with a paper popper. Cause static cling with a tissue-paper doll. Other experiments work with chemistry, light, motion, math, and water. It's the perfect combination of science and play--100 times over!
