Everything around you is made up of materials. We use materials to make objects such as tables and chairs, shoes and clothes, cars and aircraft. This book looks at how materials can be mixed and separated. When two materials are mixed together they can be separated by sieving, filtering, skimming or by evaporation. But when some materials are mixed together they cannot be separated because the materials have changed forever.
Everything around you is made up of materials. We use materials to make objects such as tables and chairs, shoes and clothes, cars and aircraft. Some materials come in blocks or sheets. Others come as liquids or powders. We have to shape them to turn them in to objects. This book looks at the ways we shape different materials, for example by cutting, folding or moulding.
Everything around you is made up of materials. We use materials to make objects such as tables and chairs, shoes and clothes, cars and aircraft. This book looks at how materials can change. Some materials, such as clay or plasticine, can change shape. Some materials, such as water, can freeze, condense or evaporate. Some materials can dissolve, such as sugar or salt, and some can change for ever, such as candles or wood.
Everything around you is made up of materials to make objects such as tables and chairs, shoes and clothes, cars and aircraft. This book look at how materials can be joined. Some materials can be joined using nuts, bolts, thread, staples or glue. Other materials can be welded or soldered together to make a strong joint.
This series covers the core science concept of how materials can be changed by physical processes such as heating. Each book uses real-life examples to illustrate the effects.
