  3. 3. Not matter <ul><li>It is the matter that we can’t see </li></ul>

  5. 5. Element <ul><li>one of a class of substances that cannot be separated into simpler substances by chemical means </li></ul>It is Element because this substance cannot be separates to simple substances
  6. 6. Compounds <ul><li>composed of two or more parts, elements, or ingredients </li></ul>Soap has 2 and others matter.
  7. 7. Mixture <ul><li>any combination or blend of different elements, kinds, qualities </li></ul>It has salt and water, it is mixed
  8. 8. Heterogeneous Mixture <ul><li>The matters aren’t have exactly same ration </li></ul>Milk isn’t exactly knows about real ration
  9. 9. Homogenous Mixtures <ul><li>The mixture of the matter’s rations have exactly same. </li></ul>We can know the ration of sugar water exactly.
  10. 10. Mass <ul><li>Of an object is a measure of the amount of matter in the object, that object’s mass stays constant every where in the universe. </li></ul><ul><li>1KG=1000g </li></ul>
  11. 11. Volume <ul><li>It is the matter that takes a space </li></ul>It has a height, length and side
