Learning About

Keywords:

Particle: Small part of matter. (2)
Solid: Contain closely packed particles which may vibrate but remain in position. Attraction between particles is very strong but kinetic energy of particles is very low. (2)
Gas: Particles are spread apart and move about randomly. So they have high amounts of kinetic energy but attraction between particles is weak. (2)
Liquid: Particles are touching but able to freely move over each other, resulting in substances in this state having no fixed shape. . Particles have moderate kinetic energy and attraction. (2)
Lattice: a regular repeated three-dimensional arrangement. (1)
Matter: Any substance that occupies space and possesses mass. (1)

Method	Precise Learning Objective	Question / Activity (Designed for maximum working out)
W	Solids hold their shape.	What are the properties of solids? Demo Solid, liquid, Gas in a beaker
W	Liquids take the shape of the bottom of their containers.	What are the properties of liquids? class practical
W	Gases fill their containers.	What are the properties of gases?
W	Liquids and gases are known as fluids because they can flow.	What is a fluid?
T	All matter (stuff) is made of particles.	What is anything with mass made of?
T	Particles in a solid form a lattice - regular pattern.	How are the particles arranged in solids?
T	Particles in a liquid are touching, but have no pattern.	How are the particles arranged in liquids?
T	Particles in a gas are spread out, with no pattern.	How are the particles arranged in gases?
T	Particles in a gas and liquids can move relative to each other, that is why they have no pattern.
W	When particles can move relative to each other, the material can flow.	What property do substances which have particles that are able to move relative to each other have?
T	The is no such thing as liquid or solid particles.
