We need to change science lessons so that they give children a correct view of modern science. Children are often taught in science lessons that matter can exist in three different states – solid, liquid and gas. However, developments in science suggest that this is far too simple a picture. Increased knowledge of the universe has shown that many other states of matter exist, for example, plasma and liquid crystal. Plasma is thought to be the state of 99% of matter in the universe, so the traditional states of matter are in a very small minority. So the traditional view is giving children a false, indeed unscientific, view of the universe.
