1. Focus Activity: Reading Check- POP QUIZ- copy down the homework and then clear off your desk.
Homework: Find/Draw pictures/diagrams for your foldable flipbook.

2. Compound Heterogeneous
Focus Activity: Get 1 of each of the colored sheets of colored paper. Put the bright pink on top of the lavender on top of the gold on top of the blue. Shift each paper up so that 1.5 cm of the color is showing. Fold from the top down so that the 2 bright pink parts meet. See Board for Example!! See below for labeling.

6. Matter – top page flap Anything that has mass and takes up space
Matter can have many different properties or characteristics.
These properties and characteristics are used to classify matter in much the same way that the characteristics of living things are used to classify organisms.
Chemistry is the study of the properties of matter and how matter changes.

7. Substance Matter that is pure
Has a specific composition (what it’s made of) All particles are the same.
Specific properties
Properties
Physical – characteristic of a pure substance that can be observed without changing it into another substance Examples of physical properties are: boiling point and freezing point, hardness, texture, color, solubility, phase of matter, flexibility, magnetism, conductivity, etc.
Chemical – characteristic of a pure substance that describes its ability to change into different substances Examples of chemical properties are flammability and reactivity with other substances.

8. Take a baggie. Sort the objects in your baggies into 3 groups
Take a baggie. Sort the objects in your baggies into 3 groups. Describe the differences between the groups and make a list of characteristics.

9. Examples of Substances
Has specific properties
All the Same
Has a specific composition.

10. Elements
Pure substance that can not be broken down into any other substances by chemical or physical means.
Composed of identical
atoms.

11. Atoms
Basic particle from which all elements are made.

12. Compounds -composed of 2 or more elements in a fixed ratio
properties differ from those of the individual elements
Chemical Bonds hold the elements together
EX: table salt (NaCl)

13. Molecules Groups of two or more atoms bound by chemical bonds
Can be two of the same element

14. Focus Activity: Make a graphic organizer to…
Show the relationships between:
Substances
Atoms
Compounds
Molecules
Elements
Grab a markerboard, marker and sock, place it under your desk for use later in the period. DO NOT DRAW ON THE MARKERBOARD!

15. Chemical Formula-Extra Info
Shows the compound and the ratio of atoms.

16. Mixtures
Variable combination of 2 or more pure substances. Each keep individual properties
Heterogeneous –
You can see the different Parts
Homogeneous –
Evenly Mixed
Can not see the different
Parts

17. Tyndall Effect (Extra Info)
The scattering
of light by particles
in a mixture

18. Mixtures Suspension heterogeneous large particles Tyndall effect
particles settle
EX:
fresh-squeezed lemonade
Sand in water

19. Mixtures Colloid heterogeneous medium-sized particles Tyndall effect
particles don’t settle
EX:
milk
Clouds
Smoke
mayo

20. Mixtures Solution very small particles homogeneous no Tyndall effect
particles don’t settle
EX:
rubbing alcohol (ethyl alcohol and water)
Air (N2 + O2)

21. What type of Mixture am I?
Colloid
Suspension
Solution
mayonnaise
muddy water
fog
saltwater
Italian salad dressing

23. Pure Substances (Extra Info)
Law of Definite Composition
A given compound always contains the same, fixed ratio of elements.
Two different compounds, each has a definite composition.

24. Pure Substances (Extra Info)
Law of Multiple Proportions
Elements can combine in different ratios to form different compounds.
