The Particle Model
You can use the idea of particles to explain the properties of solids, liquids and gases.The strength of bonds between particles is different in all three states. It explains why solids cannot flow, and why gases can be compressed.
Solids Liquids Gases Flowing Arrangement and movement
Behaviour of matter
Solids, liquids and gasses have physical properties. The way they behave is affected by heating and cooling. We will also look at pressure and diffusion in gases.
Expansion and contraction Pressure in gases Diffusion
Energy, electricity and forces TOP of Key stage 3Energy comes from renewable and non-renewable sources. Electrical energy is a measurable force that also creates magnetic fields.
This section includes Energy transfer and storage, Forces, Electric Current and Voltage, Magnets and electric current
|Energy transfer and storage
Energy can be stored or transferred from place to place in different ways. Let's look at some examples
Energy basics Energy transfer diagrams Heat and temperature Transfer of thermal energy
Non-renewable resources Renewable resources Saving energy
Forces can change the shape of objects and change the way they are moving. Weight, pressure and turning moments are all the result of forces too.
Electric circuits can be series or parallel. You need to know the symbols we use to draw circuit diagrams. An ammeter measures electric current, in amps, by measuring how much charge is flowing in the circuit. A voltmeter measures, in volts, the difference in electrical energy between two points of a circuit.
Electric charge Circuit symbols Series circuits and parallel circuits Measuring current and voltage Current in series circuits
|Organisms, behaviour and health TOP
Life processes, cells, health, variation and classification, feeding relationships
Humans, animals and plants have similar life processes. But, the cell functions, reproductive patterns, food chains and behaviour are very different for each species.
There are seven processes that are common to living things. These seven processes are movement, respiration, sensitivity, growth, reproduction, excretion and nutrition.

|The Environment, the Earth and the Universe TOP
Learn about the rock forms and habitats on Earth. And find out more about our planet and where it fits into the solar system.
|The Rock cycle
This Revision Bite looks at the three types of rock: sedimentary, igneous and metamorphic. It looks at how they are formed, the weathering of rocks and the way one form of rock turns into another, in the rock cycle.
What are rocks? Sedimentary rocks Igneous rocks Metamorphic rocks
Weathering Erosion and transport The rock cycle
Astronomy and Space Science
The solar system contains planets, their satellites, asteroids and comets. The planets orbit the Sun and take different amounts of time to do this.
We have night and day on Earth because the Earth spins on its axis. The tilt of the Earth's axis causes the seasons to change as we orbit the Sun in one Earth year.
The solar system Gravitational forces Days and nights Years and seasons
The Moon Artificial satellites and space probes
Changes in the Environment
This Revision Bite is about the relationships between organisms and the environments they live in.
A changing environment Extinction Humans and the environment Pollution Climate change
