1. MATTER (S UBSTANCES ) M1

2. C LASSIFYING M ATTER Element - a pure substance Compound – 2 or more elements chemically combined Mixture – 2 or more substances physically combined

3. ELEMENT

4. COMPOUND

5. MIXTURE

7. MIXTURES Solution – a clear mixture (less than 1nm diameter in it) Colloid – a cloudy substance (1nm to 1,000 m in diameter) Suspension – a muddy substance (more than 1,000 nm in diameter)

8. SOLUTIONS

9. COLLOIDS

10. SUSPENSIONS

11. STATE OF MATTER Solid – has volume and shape Liquid – has volume, no definite shape Gas – no definite volume and shape

12. CLASSIFY ELEMENTS Metals – solid at room temperature except mercury (ductile, malleable, good conductors, high boiling point & melting points) Non-metals – mostly gases (low boiling points & melting points, poor conductors) Metalloids – have both properties of metal and non-metals VOCABULARY Ductile – Malleable – Conductor

13. THE PERIODIC TABLE OF ELEMENTS

14. METALS Shiny surface Malleable Ductile Good Heat Conduction Good Electricity Conduction High Melting and boiling point PROPERTIES

15. Ductility is the ability for a material to be pulled into a thin wire. Malleability is the ability for a material to be flattened into a thin sheet.

16. G OOD VS. POOR HEAT CONDUCTION

17. N ON -M ETALS Dull Not malleable Poor Heat Conduction Poor Electricity Conduction Low melting and boiling point Brittle PROPERTIES

18. METALLOIDS

19. W ORK ASSIGNMENT CLASSWORK: Write in your notebook: 1. What is matter? 2. What are the three states of matter? Describe each one of them. LAB MATERIAL: Bring 1 pack of Ice tomorrow (whole class) HOMEWORK Find at least 5 metals and 5 non-metals in your home or in school and identify their properties and uses.

20. S CIENCE PROJECT TOPICS (EP ½) G1: What is the Effect of Salt on the Boiling Temperature of Water? G2: Does Music Have an effect on plant growth(green beans)? G3: Can We Identify the Gender by just Looking at the Hand of a Person? G4: How Can We Tell that Tomato is a Fruit or a Vegetable? G5: Does Music Affect on Animal Behavior (dogs & cats)?
