1. What’s the Matter? by Ms. Reardon

2. Standards: S.5.P.1 Students will verify that an object is the sum of its parts. a. Demonstrate that the mass of an object is equal to the sum of its parts by manipulating and measuring different objects made of various parts. b. Investigate how common items have parts that are too small to be seen without magnification. S.5.P.2 Students will explain the difference between a physical change and a chemical change. a. Investigate physical changes by separating mixtures and manipulating (cutting, tearing, folding) paper to demonstrate examples of physical change. b. Recognize that the changes in state of water ( water vapor/steam, liquid, ice) are due to temperature differences and are examples of physical change. c. Investigate the properties of a substance before, during,and after a chemical reaction to find evidence of change.

3. Let’s See What You Know About the Properties of Matter? Do you know the definition of any of these vocabulary terms? matter Physical change mass weight volume densitygravity Chemical reaction oxidation decay

4. Matter: Matter is everywhere you look, from the air you breathe to the shoes on your feet,that is because everything around you is made of matter. The definition of matter is : anything that has mass and can take up space. Objects made of matter can be very different from each other. We classify matter by their physical properties or their characteristics that can be observed or measured without changing the substance into something else.

5. Physical Properties of Matter: Many physical properties of matter can be observed, such as, color, taste, hardness… What are the physical properties of this apple? Other physical properties need to be measured. These physical properties are: mass, weight, volume, and density.

6. Mass vs. Weight: Although mass and weight may appear to be the same they are quite different. MassWeight The amount of matter in an object. A measure of the pull of gravity on an object. Measured on a balance to avoid the pull of gravity. Measured on a spring scale. (The amount the spring is squeezed depends on the pull of gravity.) Measured in grams.Measured in newtons. Which do you think is a more accurate way to measure the amount of matter in an object? Why?

7. Mass vs. Weight cont. Below are pictures of the same space shuttle, look carefully at the pictures to answer these questions. How does the mass of space shuttle A compare to space shuttle B? Explain. How does the weight of space shuttle A compare to space shuttle B? Explain. Space Shuttle A Space Shuttle B

8. Volume: Volume is the amount of space that an object takes up. Measuring Volume: graduated cylinder (for liquids) Read in milliliters ( always read from the bottom of the curve) calculate (for solids with a regular shape) Volume = length x width x height (measured in cm3) displacement (for irregular shaped objects) The volume is the difference between the volume of your liquid before and after.

9. Density: Density is the concentration of matter in an object. It is the amount of matter in a certain volume. Density = mass / volume Density is measured in g/cm3

10. Review of Physical Properties of Matter: 1) How can physical properties be used to identify objects and substances? 2) Does an object on Earth have the same mass as it does on the moon? 3) What physical properties are used to calculate the density of an object?

11. The States of Matter Do you know the four states of matter? SOLID Matter in its most rigid state that take up a definite amount of space Has a definite shape LIQUID Particles can slide past each other. Takes up a definite amount of space Does NOT have a definite shape GAS Particles can move past each other easily. Does NOT take up a definite amount of space Does NOT have a definite shape *PLAS mA Rarely occurs naturally on Earth’s surface Made of electrically charged particles of matter that glow
