  • 1. Identifying Chemistry In Our World By Hannah Lim
  • 2.
    • What is MATTER?
    • Is FIRE matter?
    • What is matter and what is not
    • Vocabulary
    • References
    - Content -
  • 3. What is MATTER?
    • Matter is thing that has volume and mass
    I am matter too!
  • 4. Is FIRE matter?
    • YES fire is a matter!!
    • Why- Many people think fire don’t has mass but fire use oxygen to burn so fire has mass. Of course it has volume because it o ccupy place to burn .
  • 5. What is matter and what is not
    • Matter- air, desk, water, fire and me (people)
    • Not Matter- light, time, motion
    ← Time is not a matter ← Papers are matter
  • 6. Vocabulary 7-21
  • 7. Matter
    • Matter is the thing that has volume and mass.
    • For example food, human, and water are matter.
    Sun and moon is matter too.
  • 8. Not Matter
    • Not matter is thing that neither has volume nor mass.
    • For example time, shadow, light, and motion are not matter.
    Love is not matter. ← Love is feeling. Sun light!!
  • 9. Pure Substance
    • Pure substance is matter that has only 1 chemical.
    • For example pure water, gold, and silver are pure substance.
  • 10. Element
    • Element is 1 small chemical substance that can’t be separated.
    It’s Periodic Table
  • 11. Compounds
    • Compounds are 2 or more elements combined together.
    H2 Water= O O H2 O O Water=H2O=H2+O+O
  • 12. Mixtures
    • Mixtures are 2 or more elements mixed with no chemical reaction.
    A and B is mixed together.
  • 13. Heterogeneous Mixtures
    • Heterogeneous mixtures are different parts of mixtures that we can clarify easily.
    • For example we can clarify cereal easily by just looking at it.
    Strawberry, corns, and milk!!
  • 14. Homogenous Mixtures
    • Homogenous mixtures are mixtures that look like a mixture when something mixed together.
    • For example coffee is made of sugar, water, milk, and coffee bean flour.
    It’s made of sugar, water, milk, coffee bean flour , and cream!
  • 15. Mass
    • Mass is amount of matter in particular thing.
    • Shadow has no mass
    Our body has mass too!!
  • 16. Volume
    • Volume is amount of space that matter takes place.
    Balloon has volume too.
  • 17. Suspension
    • Suspension is liquid with some solid matter in it and it cannot be dissolved.
  • 18. Emulsion
    • Emulsion is liquid or thing when you can see the different substances in a mixture
    • For example oil and water is emulsion.
  • 19. Mechanical Mixture
    • Mechanical mixture is mixture which can be separated by mechanical way.
  • 20. Reversible Change
    • Reversible change is mixture that can be separated like before it mixed.
    • For example salt water is reversible change.
    Dissolve salt in water Water evaporate! Salt!!
  • 21. Non-Reversible Change
    • Non-reversible change is matter that can’t be separated from when it mixed.
    • For example milk can’t be separated.
  • 22. Physical Change
    • Physical change is that something changed physically, and we can see the change.
    • If I rip the paper it’s physical change.
    • If salt dissolve in the water it’s physical change.
  • 23. Chemical Change
    • Chemical change is like water evaporating, water freeze, and ice melt.
  • 24. Pictures Matter Not Matter
