Flour can be poured and take the shape of its container, like a liquid, but it also can be picked up and held, like a solid. A cluster of non-metal atoms that are chemically bonded together. Ask students to watch closely as you add one or two drops of food coloring to the water. A gas is a substance that behaves like the air around us. The particles of a liquid are attracted to one another, are in motion, and are able to move past one another. Adding heat energy to particles either raises the temperature and they move faster, or bonds are broken to change from solid to liquid (melting) or liquid to gas (boiling). You need to ask yourself questions and then do problems to answer those questions. Carbohydrates and fats are made up of carbon, hydrogen and oxygen. Give students time after the activity to record their observations by answering the following questions on their activity sheet. There are some gaps, but liquids cannot usually be compressed or squashed. SOLIDS, LIQUIDS AND GASES DEFINITION.
