1 Types of Mixtures

2 Mixtures They are substances held together by physical forces, not chemical and are not chemically combined. This mean a mixture will keep it’s own identity. Can be separated by simple physical methods. Images are from

3 Heterogeneous The substances are not uniformly mixed.
Different substances can be seen. Example: Sand in a glass of water, cookie dough, lucky charms.

4 Homogeneous Uniformly distributed (are evenly mixed)
Particles are very small -- it is difficult to see each substance in the mixture. Examples: sugar and water, milk, air. Images are from

5 Types of Homogeneous Mixtures
Solutions – Well mixed mixtures that have the same properties throughout. (particles can’t bee seen and don’t settle over time) Examples: Colloids – well mixed mixture that has undissolved particles that will not settle over time.

6 Separating Mixtures

7 Physically picking apart a Mixture by hand
Picking apart different substances from a mixture and placing them in different containers or piles

8 Sieving Using screens of different sizes to separate a mixture into its different sized components.

9 Magnets Magnetic attraction can be used to separate the metals Iron (Fe), Nickel (Ni), and Cobalt (Co) from a mixture.

10 Filtration Using filters to separate solid materials from liquids

11 Decanting Pouring off liquids for solids

12 Evaporation or Boiling
Evaporation or boiling off a liquid separates liquids for dissolved solids

13 Distillation Separation of 2 liquids with different boiling point temperatures

14 Centrifuge Separates substances of different densities
Solids from liquids Different density liquids Blood platelets from blood plasma
