8. Matter and Physical Properties  Matter has in own sets of physical properties and can be used to identify an object by its name.  They can be observed and measured.

9. Observable Properties of Matter Physical properties can be observed using your 5 senses. Sight Sound Smell Taste but not in the laboratory Tactile Physical properties that can be observed include: colortastehardness conductivitymagnetismsolubility

10. Measurable Properties of Matter  Measurements in Science are especially useful because they provide more exact descriptions of matter than direct observations do.  Examples of measurements of physical properties include:  mass  weight  length/distance  volume  density  temperatures  time

11. Mass and Weight Mass Amount of matter in an object A balance can be used to measure mass. Mass stays the same between place to place. Weight Amount of matter pulled by the force of gravity. A weight/spring scale can be used to measure weight. Weight changes between place to place. Example: On Earth if you weigh 60 pounds, then you would weigh 10 pounds on the Moon. If the mass of an object is 10 kilograms on Earth, then it would have the same mass on the Moon. Measure in grams and kilograms

12. Measureable Physical Property: Volume  Volume is the amount of space that an object takes up.  There are several different ways of measuring volume:  graduated cylinder  graduated beaker  measuring cup  rain gauge  Volume can be found by multiplying length x width x height in regular shapes.  V = l x w x h

13. Volume Continued  One way to find the volume of irregular shaped objects is through the displacement of water in a measuring container.  Partially fill a measuring container with water.  Write down the beginning volume.  Place a solid in a liquid.  The level of the liquid will rise.  Write down the ending volume after the displacement.  Find the difference between the beginning volume and the ending volume.  Example: Ending Volume – Beginning Volume = Volume of irregular shaped object 57 ml - 50 ml= 7 cm³

14. Density  It is a characteristic property of matter.  It is unique and it will NEVER change.  When an object/matter sinks in water, we say that it is denser than water.  When an object/matter floats in water, we say that is less dense than water..  Density is found by using the following formula:  Density = Mass ÷ Volume
