(Material) 1. Metals can be beaten into sheets. What is that property called? 2. Why is copper used to make wire in circuit? 3. Class 6 want to find out which material is best at keeping drinking chocolate hot. The class have four identical plastic cups. They wrap each one in a different material. They put the same amount of chocolate drink in each cup and put lids on. ( Newspaper, Foil, Food wrap, Bubble wrap ) what property the material should have if it is best at keeping the drink hot. The material should be 4. A material that does NOT let electricity pass through it is called. 5. Draw a line to match the best material for each of these uses. Used for building walls as it is strong glass and can be joined together. paper Used for windows as light passes metal through it easily. metal Used to make water pipes as it brick is strong, but easy to shape into hollow, watertight tubes. 6. What is the correct order of materials, from the best insulator to the worst? A B C D ceramic, polystyrene, plastic, metal metal, ceramic, plastic, polystyrene polystyrene, plastic, ceramic, metal polystyrene, plastic, metal, ceramic 7. Most magnets are made of A B C Iron or paper Paper or steel Iron or steel 8. Stainless steel pans are usually provided with copper bottoms. The reason for this could be that A B C D copper bottom makes the pan more durable. such pans appear colourful. copper is a better conductor of heat than the stainless steel. copper is easier to clean than the stainless steel. 9. Modern aircraft are made of aluminum, this is because it is A brittle. B lightweight. C elastic. D magnetic. 10.The temperature of something is best measured with... Your hands a thermometer a clock 3
11.Temperature is measured in... Kilograms degrees degrees Celsius 12.What do we call materials that let heat pass through them easily? Thermal conductors thermal insulators transparent 13.Which of these is a good thermal conductor? Plastic wood steel 14.What do we call materials that do NOT let heat pass through them easily? Thermal conductors Thermal insulators Opaque 15.Which of these is a good thermal insulator? Steel, iron, Polystyrene 16.Which one of these things can a thermal insulator NOT do? Keep cold things cold Make cold things hot Keep warm things warm 17.To save on heating bills, do you think the roof of a building should be lined with... a thermal conductor a thermal insulator nothing 18.A room at a temperature of 20 degrees Celsius would feel colder than a room at a temperature of -20 degrees Celsius. True or false? True False They would both feel equally cold 19.How does heat travel? From cold things to hotter things From hot things to colder things Between things of the same temperature 4
Separation of Materials 1. Which of these materials will dissolve in water? sand salt sugar clay chalk wax 2. When a solid is dissolved in water, what is the mixture called? sludge, solution, powder, filter 3. Tom had 3 powders. He added 20g of powder A to jar A. He added 20g of powder B to jar B. He added 20g of powder C to jar C. Each jar contained 100ml of water at the same temperature. He stirred the water in each jar ten times. Explain what happened to the powder in jar B when it was added to the water and stirred....... 4. When a solid dissolves what happens to the particles of the solid? They disappear they change colour they are still there but are too small to be seen 5. Sieving would separate which of these mixtures? Salt and water Sand and salt Sand and gravel Soil and salt 6. What is a suspension? A mixture created by combining two liquids A mixture of two gases A clear solution A mixture of a solid and liquid, where the solid will not dissolve in the liquid 7. Which of these would help sugar dissolve more quickly in coffee? Using hot coffee Using cold coffee Using cold sugar Not disturbing the sugar as it dissolves 8. What is a solvent? The material which has been dissolved in a liquid The liquid in which a material has been dissolved. The particles remaining in suspension 9. If you mixed sand, sugar and water, which material would dissolve? The material left after evaporation Sand Sugar Sand and sugar Neither sand nor sugar 10. Which of these materials would not dissolve in water? Icing sugar Gelatine crystals A candle sea salt 11. When a material is dissolved, what does it make? A new substance or material A gas A solution A force 12.
