  1. Anything that takes up space (volume) and has mass
    matter
  2. Describe the size of matter particles
    Atoms are too small to be seen
  3. Describe the properties of a solid
    • definite volume
    • definite shape
    • particles close together 
    • vibrate, but stay in one place
  4. Describe the properties of a liquid
    • definite volume
    • takes on the shape of its container
    • particles are close together but able to move apart and flow
  5. Describe the properties of a gas
    • definite volume
    • take on the shape and volume of container
    • filing the space
    • particles move far apart
  6. How is the volume of a rectangular solid calculated?
    • Measure with ruler then use formula V=LxWxH
    • (Volume= Length x Width x Height)
  7. How is the volume of an irregular figure calculated?
    Displacement
  8. how is the volume of a liquid calculated?
    • graduated cylinder (ex: measuring cup)
    • syringe
  9. What is a mixture?
    • 2 substances combined together, each substance keeps the original property
    • made up of 2 or more substances mixed together, but can be separated 
    • ex: chex mix
  10. Do the substances that make up a mixture change? Explain:
    • No they do not change
    • they keep their separate properties
  11. What is a solution?
    • made when a solid dissolves in a liquid
    • mixture made up of 2 or more substances mixed together so completely that can not be distinguished as separate or individual substances
    • ex: lemonade or kool aid
  12. Do the substances that make up a solution change? explain:
    • Yes they do change
    • they mix so completely that you can't tell them apart the solid dissolved in the liquid
    • ex: lemonade or kool aid
  13. What is an example of a mixture?
    Trail Mix (chex mix)
  14. What is an example of a solution?
    Lemonade or kool-aid
  15. Is a mixture a solution?
    No
  16. Is a solution a mixture?
    • Yes  
    • special kind of mixture (solute must dissolve)
  17. What is filtration used for?
    to separate solid particles from a liquid
  18. How does filtration work?
    Pour mixture through filter paper in a funnel to trap the solid particles.
  19. Give an example of filtration…
    • water treatment plants do to make water clean enough to drink
    • Make coffee using a coffee filter, the filter prevents the coffee grinds from getting into coffee
  20. What is sifting?
    • separating smaller particles from larger particles 
    • sifting flower
  21. How does sifting work?
    A mixture of different sizes of particles can be put in container that has a screen at the bottom
