Lesson 3 matter
- 2. MATTER Science Teacher: T. Jen
- 3. What is MATTER? Matter is any living or non-living things in the universe All objects, things, plants, people, animals, etc are made up of matter.
- 4. What are the matters?
- 5. OBJECTIVES • Describe what matter is made up of • Distinguish between the physical properties and chemical properties of matter • Classify changes of matter as physical or chemical. • Cite the importance of matter in our daily life
- 6. Matter • Matter has mass and volume.
- 7. Mass: •the amount of matter in an object •measured with a balance
- 9. Volume: •the amount of space an object takes up •measured with a ruler or graduated cylinder
- 10. Matter • Matter is composed of tiny particles called atoms.
- 11. Atoms • Atoms are the basic building blocks of ordinary matter.
- 12. PARTS OF ATOM
- 13. • Molecules is a large particle formed by the combination of two or more atoms by chemical bonds
- 14. What matter can you observe in this picture?
- 15. What matter can you observe in this picture?
- 18. Physical Properties • are those that can be observed and measured without changing the substance into another substance. • changes in the size or shape of matter. • Changes of state—for example, from solid to liquid or from liquid to gas.
- 20. Physical Properties • Some of the processes that cause physical changes include cutting, bending, dissolving, freezing, boiling, and melting.
- 22. Examples include 1. Boiling point 2. Melting point 3. Malleability and Ductility
- 23. 1. Boiling Point - Is the temperature at which a liquid starts changing into gaseous phase.
- 24. 2. Melting Point - Is the temperature at which solid begins to melt.
- 25. 3. Metallic properties Malleability is the capacity of a material to be hammered into thin sheets. Ductility is the ability of a material to be drawn into wires.
- 27. Physical Changes terms to consider… Boil, melt, cut, break, split, grind, crush, bend, condense, freeze, dissolve and crack are examples of physical changes. ,
- 28. Chemical Properties • Are properties that can only be identified when one substance reacts with another substance. • Ability of a substance to undergo a chemical reaction C + O2 (reactants) CO2 (product)
- 29. If you cut an apple, the flesh of apples turn brown due to oxidation.
- 30. Chemical Properties Characteristics: 1.Change in odor 2.Change in color 3.Change in form 4.Change in temperature or energy 5.Form gas 6.Give off light and heat 7.Form precipitate
- 31. • Example include: –Charcoal burning in air – iron rust –Decomposition of wood Chemical Properties
- 32. CHEMICAL PROPERTIES •Consider terms such as: –burn –rot –rust –decompose –ferment –explode –oxidize –corrode –grow –precipitate –gas formation –digest
