Today I will be able to:
Differentiate between the properties of solids liquids and gases
Differentiate between elements, compounds and mixtures by completing a close reading
Differentiate between a element, compound, homogeneous or heterogeneous mixture
Informal assessment – monitor student interactions as they complete the practice
Formal assessment – analyze student responses to the exit ticket and concept maps
Common core connection
Build Strong Content Knowledge
Value Evidence
Reason abstractly and quantitatively

Homogeneous
Heterogeneous

12. Mixtures

13. Mixtures
Two or more substances together which are NOT chemically combined
Properties
- Substances keep separate identities and properties
- Substances may be present in any amount
- Substances can be separated by simple physical means (filtering, magnet, etc)

14. Mixtures
Heterogeneous - not the same throughout (trail mix, bird seed)
- Particles are large enough to be seen
- Mixtures separate on standing

15. Mixtures Homogeneous - the same throughout (salt water)
- Particles are small and not easily recognized – uniform mixture of particles
- Does not settle on standing

16. Mixtures Solution – example of a homogeneous mixture
- one substance dissolved in another (lemonade, ocean water, gold jewelry)
- Particles are very small and evenly spread out
- Cannot be separated by simple physical means

17. Pure Substances

18. Elements
Pure substance that cannot be broken down into simpler substances by ordinary chemical means (Iron, Copper, Tungsten)

19. Elements All matter is composed of elements Have definite properties
Made up of one type of atom
Periodic Table organizes elements according to their properties

20. Compounds
Two or more different elements combine in a chemical reaction
New substances with new properties are formed
Elements combine in fixed proportions
- water (H2O) always has two hydrogen atoms and one oxygen atom

21. Compounds Examples of Fixed Proportions C3H7OH - Propanol
- 3 carbon, 8 hydrogen, 1 oxygen
(NH4)2O – Ammonium Oxide
- 2 nitrogen, 8 hydrogen, 1 oxygen

22. Compounds Two elements = binary compound (CO2)
Three elements = ternary compound (C6H12O6)
