TERM TWO PLANNER CHECKLIST Natural Science and Technology - 6 MATTER AND MATERIALS DATE DATE TOPICS AND SUB-TOPICS STARTED COMPLETED TOPIC 1 (½ WEEK) SOLIDS, LIQUIDS AND GASES Arrangement of particles All matter (solids, liquids and gases) is made up of particles. • The particles are arranged differently in solids, liquids and gases. • -- In solids the particles are closely packed in a regular pattern spaces – between the particles are small and particles vibrate in one place. 1 -- In liquids the particles are closely packed in no fixed pattern spaces – between the particles are small but particles can move around each other. -- In gases the particles are far apart from each other spaces between – the particles are big and particles move in all directions. 2 (1 WEEK) MIXTURES Mixtures of materials A mixture consists of at least two different substances/materials mixed • together In some mixtures, the different substances are clearly visible after 3 • mixing -- The substances in such mixtures can be separated by physical such as sieving, filtering, hand sorting, settling and decanting.
