9 What is matter? Anything that has mass and takes up space Yes or no Air Light Noise Sunlight Person

10 Physical property Any characteristic of a material that can be observed or measured without changing the identity of the material

11 Make a foldable “Physical properties” 8 slits Mass – add this today Volume – add this today Density Boiling point Melting point Color, shape, size State of matter

12 Matter and Its Changes Measurements

13 Bellringers 11/18/09 Please write the questions and correct answer 1. Which object would have the greatest mass? A. Balloon B.feather C.baseball D.pencil 2. Which object would have the least volume? A.balloon B.ring C.baseball D.pencil

14 Review During the previous classes, we learned about matter. Not all things are classified as matter. Light, sound, and emotions are not matter. Matter must have mass and take up space. We have learned that matter can be described using physical properties. Physical properties can be observed or measured without changing the identity of the substance. We have briefly looked at how to obtain mass and volume using instruments and tools. We learned that the volume of an object can be obtained by either displacing water or by measuring length times width times height.

15 Preview Today we will be relating how measurements are used to describe matter. Measurements such as mass, volume, and density are used to differentiate matter. Measurements are physical properties. Hook: Students will be shown a beaker with three different liquids. This will be shaken. Why do these liquids separate into layers? The liquids have different densities. Students will be shown two tennis balls which look the same. However, they will realize that one is much heavier than the other.

16 Mass and volume Mass – amount of material in an object Use a scale (weight in grams) Volume – amount of space an object takes up Use a ruler to find length x width x height in cm Use a beaker to find out how much water is displaced (ml or cc; cm³)

17 Density Density – the amount of mass per volume Formula Density = mass / volume OR d = m/v

18 Video clip chemistry/measuringmatter/ chemistry/measuringmatter/ “Measuring matter”

19 Practice density BrainPOP graphic organizer and “Use the formula” worksheet(s)

20 Model density 1. Obtain the mass on the scale 2. Determine how you will obtain the volume Ask yourself: will it be by placing the object in water OR by measuring length x width X height

21 Hands-on density practice Find the density of the rock

22 Formative assessment 1. What is the correct formula to obtain density? A. Mass / volume B. Volume / mass C. Density / volume D. None of the above 2. What object would have the greatest density? A. Balloon B. Bowling ball C. Kickball 3. What is the density of a ball that has a mass of 40 grams and a volume of 10 cm³? A. 1 g / 4 cm³ B. 1 cm³ / 4 g C. 4 g / cm³

24 Metal properties Luster-does it shine? Malleability- can be hammered into thin sheets Ductility- can be drawn into wire Magnetism- attracted to a magnet

25 Metal video chemistry/metals/ chemistry/metals/ “Metals”

26 Give examples of objects in the classroom and not found in the classroom that have a metallic luster

27 Bellringer- 11/30/09 Match the following properties with their descriptions: 1. lusterA. Wiring in a house 2. malleableB. Paper clip picked up by 3. ductilea magnet 4. magnetismC. Aluminum foil is a thin sheet D. A shiny penny

28 Boiling point vs. Melting point Boiling point – temperature that a liquid boils to gas Water = 100˚ C or above (212˚F) Melting point – temperature that a solid melts into a liquid Water = 0˚ C or above (32 ˚F) Freezing point – temperature that a liquid freezes into a solid Water = 0˚ C or below (32 ˚F) Each of these temps are different for different materials
