1. Properties of Matter

2. Classifying Matter Matter- anything that has mass and takes up space 2 categories 1.Mixtures- contain more than one kind of matter that can be separated out 2. Substances Some are made up of only one kind of matter - elements Some are made of more than one kind of matter but cannot be separated without changing the substance

3. Mixtures Homogeneous mixture- contains more than one type of matter and is the same throughout(soda pop, air, chocolate ice cream) Heterogeneous mixture- contains more than one type of matter and is not the same throughout (chicken noodle soup)

4. Substances All substances are either elements or compounds Elements Compounds- substances that are made of 2 or more elements that cannot be separated by physical means

5. Measuring Matter Mass- the amount of matter an object has Volume- the amount of space an object takes up Density

6. Volume Rectangular solid or cube –Length x width x height Cylinder –pi x radius 2 x height Cone –1/3 x pi x radius 2 x height Sphere –4/3 x pi x radius 3

7. Volume Irregular shapes? –Displacement method Use graduated cylinder Object displaces water Read water level at the bottom of the meniscus

8. Mass Use a scale- measures the gravitational force between an object and Earth, calculates mass from weight Use a balance- measures mass of unknown object by comparing it with objects whose masses are known

9. Mass Measuring very large and very small amounts –Use indirect measurement (pg 282)

10. States of Matter Molecule- smallest particle of a compound that retains the properties of the compound Atom- smallest particle of an element

11. Water Compound Each molecule has one atom of oxygen ad 3 atoms of hydrogen

12. Mixtures

13. The Building Blocks Atoms Molecules

14. The Atom Building blocks of matter –Subatomic particles Electrons Protons Neutrons
