Across
- 2. made from wood that has been chopped very small and turned into “pulp”, which is then bleached, flattened, cut, and dried
- 4. bright reddish color, easy to form and mold, good electric and heat conductor, a bit expensive, used in electrical cables and heating pipes
- 6. silver color, very light, soft and easy to shape, used for drink cans, many kitchen things, and building materials
- 8. hardwood, resistant, durable, very hard, heavy, expensive
- 9. hardwood, flexible, often used in furniture
- 10. taken directly from tree trunks, classified as hardwood or softwood
- 12. separating the metal from inside a mineral, usually for steel and iron
- 14. turning metals into useful products
- 15. softwood, cheap, resistant, easy to work with, durable (lasts a long time)
- 17. bluish white color, soft, resistant to rust, used in a lot of things to prevent rust and erosion
- 20. copper/zinc alloy, bright yellow, easy to shape and mold, used in hardware and musical instruments
- 21. metals that contain iron, classified by amount of carbon they contain (soft iron, steel, cast iron)
- 23. can be shaped using a hammer, light gray or silver, not used in many things
- 25. extracting materials from the Earth’s crust
- 26. tropical wood, very durable for use outside, does not rot
- 27. softwood, doesn’t last long, rots easily, found in the mountains of the Iberian Peninsula
- 28. made from combining particles (pieces) of wood with glue to make new boards
- 29. resistant to being stretched or bent, soft enough for screws and nails, electrical and thermal insulator, biodegradable, float in water
Down
- 1. easy to weld, high mechanical strength, lower price, most commonly used type of iron
- 3. metals that do not contain iron, classified by density, do not rust, conduct heat and electricity better, melt at lower temperatures
- 5. several different woods combined into stronger boards
- 7. very light, very expensive, flammable, used in fireworks and automotive components
- 11. boards lower quality wood made into larger boards, less expensive, usually very strong
- 13. soft, heavy, toxic, easy to mold, used in car batteries and x-ray technology
- 14. good heat and electricity conductors, high density (heavy), solid at room temp, shiny
- 16. very light, very hard, very expensive, bright and shiny, used in medicine because the human body does not reject it
- 18. melts easily, cannot be forged or welded, cheaper than steel, mostly used in engines
- 19. copper/tin alloy, dark yellow or brown, harder than copper, used in boat propellers and gears
- 22. bright white, melts easily, good electrical and thermal conductor, used in food cans mostly
- 24. plant cells from destroyed wood that are glued to make panels
