2. What is Matter? Matter is the stuff around you Anything made of atoms and molecules Anything that has mass
3. What are Elements? The building blocks of matter Cannot be broken down into another substance Image from - http://www.vaughns-1-pagers.com/biology/human-periodic-table.gif
4. Atoms The smallest particle of an element that has the properties of the element
5. Parts of an Atom Nucleus – the center of an atom Proton – particle of an atom that has a positive charge Neutron – particle of an atom that has no charge Electron – particle of an atom that has a negative charge
6. What is a Molecule? Two or more atoms joined together
7. Compound A substance made up of atoms of more than one element joined together in a molecule
8. Compare Compounds and Molecules All compounds are molecules but not all molecules are compounds. Example - O2 and N2 are molecules (not compounds) because they have a single element Example - H2O and CO2 are compounds (and molecules) because they are made from more than one element.
9. Mixture Two or more substances that are mixed together, but can be separated out because their atoms are not combined
10. Solution A mixture in which substances break up into their most basic particle Are too small to be seen Spread evenly through another substance.
11. Physical Properties The characteristics of an object that you can observe with your senses or measure. Hardness-How hard or soft is it? Texture-What is its surface like? Mass-How heavy is it? Elasticity-How much will it stretch or bend before breaking? Odor-What does it smell like? Magnetism-It it magnetic? Melting Point-At what temperature will it melt or freeze?
12. States of Matter Solid It has a definite shape. It has a definite mass. It has a definite volume.
13. States of Matter Liquid It does not have a definite shape. It has a definite mass. It has a definite volume.
14. States of Matter Gas It does not have a definite shape. It does not have a definite mass. It does not have a definite volume.
15. Physical Change A change in any physical properties of a substance, not in the substance itself.
16. Sometimes its Difficult to Tell Ask Yourself: “Do I have the same substance that I started with?” If yes, then the changes it underwent were all physical changes.
17. Chemical Properties Describes the way a substance reacts with other substances and changes into a new substance, either by combining with other elements or breaking apart into a new substance.
18. Sometimes its Difficult to Tell Chemical properties are not as easy to observe a physical properties. Observe chemical properties when a substance is being changed. Examples: Wood burning Iron rusting
19. Chemical Change A change of one substance into another substance Wood Ashes http://www.stovesonline.co.uk/stove/img/wood-burning.jpghttp://urbangardenproject.files.wordpress.com/2009/03/wood-ashes-00.jpg
