La ciencia observa english

  1. 1. Unit 1 <ul><ul><li>Science watches and measures the Universe </li></ul></ul>
  2. 2. What is the Universe? <ul><ul><li>The Universe is everything existing </li></ul></ul><ul><ul><li>Everything existing in the Universe only can be </li></ul></ul><ul><ul><li>matter or energy </li></ul></ul>
  3. 3. What is matter? <ul><li>Matter is everything that takes up space and has mass </li></ul>
  4. 4. What is energy? <ul><ul><li>Energy is everything that can work </li></ul></ul>
  5. 5. What is Sciencie? <ul><li>Science is the knowledge based on observation, experimentation and logic reasoning. </li></ul><ul><li>The scientific method is the way Science works: watching, measuring, predicting, checking... </li></ul>
  6. 6. What is ”to measure”? <ul><li>T he properties of matter that can be measured are called magnitudes </li></ul><ul><li>Ejemplos: length, volume, surface area,... </li></ul><ul><li>Base Magnitudes define themselves. Example: length . </li></ul><ul><li>Derived Magnitudes are defined from a combination of the base magnitudes. Example: speed. </li></ul>
  7. 7. To measure is to compare a propertie of an object with a standard <ul><li>The unit of measurement is a reference or standard. </li></ul><ul><li>Example: the metre . </li></ul><ul><li>The measure instrument counts how many times are the standards in the object. </li></ul><ul><li>Example: tape measure . </li></ul>
  8. 8. The International System of Measurements
  9. 9. Multiples and submultiples
  10. 10. Derived units <ul><ul><li>The derived units are obtained from a combination of the base units. They are used to measure surface area, volume, speed, density, etc. These units are the square metre, cubic metre, metre per second, etc. </li></ul></ul>
  11. 11. Properties of matter : Mass <ul><li>The mass is the amount of matter in a body. </li></ul>
  12. 12. Weight <ul><li>Weight is the force generated by the gravitational attraction of the Earth on a body. </li></ul>
  13. 13. Volume <ul><li>Volume is the amount of space occupied by an object. </li></ul>
  14. 14. Surface Area <ul><li>The surface area is the space occupied by the length and width of a body. </li></ul>
  15. 15. Density <ul><li>The density is the relationship between the mass and the volume of a body, that is, how concentrated the mass is in a specific volume. </li></ul>d = m/v
  16. 16. What is matter made off? <ul><li>All matter is made up of atoms . </li></ul><ul><li>An atom is the smallest particle of matter which can exist alone. </li></ul>
  17. 17. The structure of an atom <ul><li>Proton </li></ul><ul><li>Electron </li></ul><ul><li>Neutron </li></ul><ul><li>Quarks </li></ul>
  18. 18. How are atoms organised? <ul><li>Molécules : are made up of two or more atoms. </li></ul><ul><li>Crystals : consist of atoms or molecules arranged in a regular, organised structure. </li></ul>
  19. 19. Elements in the Universe <ul><li>All atoms in the Universe are made up of the same particles, the only difference is the number of particles. </li></ul><ul><li>The number of protons in the nucleos of an atom is the atomic number. </li></ul><ul><li>Chemical Element is a substance that contains one type of atom, so all atoms have the same atomic number . </li></ul>
  20. 20. How are elements classified?
  21. 21. Elements and compound substances <ul><li>Chemical Element is a substance that contains one type of atom. It cannot be broken down into anything simpler by chemical reaction.. </li></ul><ul><li>The combination of elements produce millions of compound substances . </li></ul><ul><li>Each element has its own chemical symbol. To describe molecules a chemical formula is used. </li></ul>
