The scientific concepts of big and small are explained in this book which is one of a series intended to encourage children to explore the science of the world around them. The concepts are explained simply and are supported by activities on every page. Activities are suggested using a variety of simple measuring devices to establish the size of objects: two different sized clay balls explain the relative sizes of Earth and Jupiter; a magnifying glass creates the illusion of size; a home-made calliper as a useful measuring instrument; a coin held up against the moon, can look the same size; a drop of water magnifies the printed word on a page; a piece of cut string measures size; a pooter for collecting insects; a method for estimating the approximate height of a tree; an arched bridge to demonstrate strength and a method for showing how atoms arrange themselves, through clustering marbles in clay.
