LESSONS

States and Bonding - Why are some compounds solids, while others are liquids or gases? Why are solids, liquids and gases in the states they are? This section looks at the particles that make up different substances. It examines how particle size and bonding affect a substance's state.

• 1 PARTICLES AND GOLF
• 3 BOILING POINTS
• 5 MORE GOLF

Properties of Metals - Why do different metals have different properties? How can we test a range of metals to find their properties? This section considers the properties that metals can have, the practical uses each can be put to, and how alloys can combine the properties of different metals.

• 7 METALWORK
• 9 TESTING METALS
• 11 BRONZE AGE

Fuels and Energy - Where does the energy in fossil fuels come from? What happens when a fuel burns? This section asks why liquid fuel is so useful and considers alternatives to petrol and diesel as a liquid fuel.

• 13 ANCIENT SUNLIGHT
• 15 NEW FUELS
• 17 DRINK DRIVING

The Periodic Table - Where are the metals, gases and halogens in the periodic table? This section looks at how the periodic table is constructed and how you can work out the likely properties of 'mystery elements' from their position in the table.

• 19 FILL IN THE BLANKS
• 21 A CARD GAME
• 23 HUNT THE ELEMENT

Chemistry and the Environment - What do you know about the chemistry of pollution: acid rain, ozone layer holes, the greenhouse effect, photochemical smog and eutrophication? This section centres on a practical experiment to identify the various pollutants released by a burning fuel.

• 25 POLLUTION IS...?
• 27 CLEAN UP
• 29 DUCKFOOD

Electrolysis - Why do some compounds conduct electricity, while others don't? What is the relationship between conductivity, charged particles and the melting point of a compound?

• 31 ELECTRIC SOUP
• 33 WHICH LIQUIDS CONDUCT?
• 35 MELTING POINT

Speeding up Reaction - How can simple chemical reactions be speeded up? This section focuses on a practical experiment, which can be undertaken as an Assessed Practical.

• 37 QUICKER REACTIONS
• 39 GRANNY'S SPEEDY TEETH
• 41 A SORT OF RIDDLE

Materials and Particles - How do the particles from which a substance is made affect the properties it has? What materials have similar particles and structures? Students undertake a wide-ranging survey of various materials, focusing on the nature of the particles and their arrangement.

• 43 LIKE PEAS IN A POD
• 45 MIXED AND MATCHED
• 47 WHAT THINGS ARE MADE OF

Chemical Equations - How can you use chemical equations to show how new substances can be made from atoms? How do equations work to show the relationship between chemical products and reactants? This section answers these questions and looks at these principles operating in the cycle of respiration and photosynthesis.

• 49 ATOMS AND MOLECULES
• 51 CHEMICAL JIGSAW
• 53 GLOBAL CHEMISTRY

How Much? How is the mass of an atom measured? What is a mole? How does it differ from a conventional number? This last section extends the pack up to Key Stage 4 Level 7 and beyond, and provides a basic introduction to quantitative chemistry.

• 55 BRICKS AND ATOMS
• 57 ATOMS IN ACTION
• 59 MOLES

• 60 Appendix: A CARD GAME
