States of Matter 06.12.17 Starter: What is an atom? What is an element? What is the difference between mixture and compound? LO: • State the 3 states of matter and List their general properties • explain the differences between physical and chemical changes • explain the limitations in the particle model using water A Element D Compound B C Mixture of elements Element E Mixture of Compounds F Compound WHAT IS MATTER? Matter is the name for the material from which everything is made up from. There are three ways in which matter can exist as: A Solid A Liquid A Gas We call these The Three States of Matter Tiny particles Scientists believe that all matter is made from tiny particles called ATOMS. The atom is the smallest unit that any matter can be made from. Atoms are arranged in different ways in solids, liquids and gases. These are called ‘ the three states of matter’ Particles are close together and can’t move around a lot Particles are close together but can move a little Particles have lots of energy and can move around Properties of solids, liquids and gases Tick the relevant boxes to show the properties of solids, liquids and gases. Property Solid Fixed shape Cannot be compressed Can flow Takes the shape of the container No fixed shape or volume Fairly easy to compress Fill in the handout 3 min Liquid Gas Answers Solid Liquid Gas Fixed shape Cannot be compressed Can flow Takes the shape of the container No fixed volume Fairly easy to compress What are the 3 states of matter? Solid Liquid Gas Fill in the blanks to complete the names of the state changes in the handout (3 min) What are the 3 states of matter? Solid melting freezing subliming condensing Liquid Gas Evaporating Fill in the blanks to complete the names of the state changes Changing States of Water -The Particles scittscience.co.uk Changing States In the boxes draw what the particles look like at each stage of the Water Cycle? www.abernet.org.uk
