Your students can learn about the motion and arrangement of particles in the states of matter with this informative presentation.   To begin with, an overview of the scientific advances that built the particle knowledge is provided. This explains how the particles give a substance its observable properties. Animated images then help to illustrate the motion and arrangement of the particles in solids, liquids and gases. Information is also provided on non-Newtonian fluids.   This resource is part of our Chemical Sciences Year 5 UNIT PLAN.
