What is Matter? Chapter 1 Section 1 pp. 4-9 Bose Einstein Condensate (B.E.C.)

Do you need a picture? Matter: Anything that has mass and takes up space p. 4

Volume p. 4 How much space something takes up! Or, the measure of how big something is in 3 dimensional space.

Volume of liquids: How much space does your water take up? Use a graduated cylinder, beaker or Erlenmeyer flask to measure. The unit we use is “liters.” p. 5

Meniscus Curve at a liquid’s surface by which one measures the volume of the liquid. P. 5 Take your reading at the bottom of the curved surface

Volume of a regularly shaped object: L X W X H p. 6

Volume of Irregular Objects: Use water displacement p. 6 1)Fill water level in graduated cylinder above the height of the object going in to the cylinder. Take a reading. 2) Place object into the cylinder. The water level will rise. Take a new reading. 3) Subtract your first reading from the second reading The amount of water displaced by the object is the “volume.” 1 ml = 1 cm ³

Matter : p 7 Anything that has mass and takes up space. Mass: The amount of matter (or stuff) inside an object. We use a triple beam balance scale to measure this. Grams are the unit of measure.

Weight: pp. 7 & 8 Measure of gravitational force on an object. Weight can change with the location of the object in the universe.

Measuring Weight p. 8 We use the spring scale to measure weight. The metric units are called “Newtons.” One Newton is about equal to the weight of an Object that has a mass of 100g. DEMO: Try to find how many Newton a random object has?

Inertia It’s a property of matter. P 8 1) It’s not a thing! 2) It’s not something you buy! 3) It is merely the tendency of an object to resist a change in motion. Pushing a more massive object can be difficult, but once you get it going, it can be difficult to stop small mass- less inertia Large mass- greater inertia

Section 1 “Summary” 1)Volume and mass are two properties of matter 2) Volume is how much space something takes up 3) We use “liters” to measure Liquids 4) Mass is the amount of matter in an object 5) We use “grams” to measure mass 6) Weight is gravitational force on an object. 7) We use “Newtons” to measure weight. This changes depending on where you are in the universe. 8) Inertia is the tendency of an object to resist being moved.

Chapter 1 Section 2 Physical Properties pp

Physical Property p A characteristic of a substance that does not involve a chemical change, such as density, color, hardness or size.

Examples: Color, smell, taste, touch, sound or noise. A) Does it conduct electricity? Is it magnetic? B) Does it dissolve in another substance? C) State of matter? Can it be stretched, rolled or pounded? What are some examples of physical properties? p.11

Density D = M / V Density = Mass Divided by Volume ____________________________________ pp

Density Calculation p. 12 A block of wood has a mass of 120 g and a volume of 300 cm ³. What is the density of the wood? D = M / VD = M / V 120 g ÷ 300 cm ³ = 0.04 g/cm ³ *Water density: 1.00 g/cm ³ Will it Float? Why?

Which has the greater density? OR Golf Ball Ping Pong Ball

Physical Changes p. 14 Do not make new substances!!!!!

Physical Changes do not change the identity of the matter. P. 15 Hmmmm, Butter!!

Section 2 Summary p. 15 1) You can observe physical properties without changing the identity 2) Some properties include: conductivity, state, malleability, ductility, solubility and density 3) Density is the amount of matter In a given space 4) Density is used to identify substances 5) Physical changes (identity stays the same) 6) Examples of physical changes include: freezing, cutting, bending, breaking, dissolving and melting

Read the Section Review from page 15. Answer questions: 1-11 Section Review p. 15

Chapter 1 Section 3 pp Chemical Properties

Chemical Property p. 16 A property of matter that describes a substance’s ability to participate in chemical reactions.

Physical vs. Chemical Properties pp. 17 Bent nail Rusty Nail Rust is the result of iron reacting with oxygen to form iron oxide.

Chemical Change pp. 18 When one or more substances change into entirely new substances with different properties. Are you able to remove certain ingredients, like eggs or milk?

Chemical Change: “Signs of Change” p. 19 Change in color, odor, production of heat, fizzing, foaming, sound or light given off. Once chemical change has occurred, the process is difficult to reverse! P. 21

Quickie Quiz p. 20 1)Give an Example of a chemical change that occurs during the preparation of a meal 2) List three clues that a chemical change might be taking place. 3) Is a broken pencil an example of a physical or chemical change? Why?

Time for Vinegar and Baking soda p. 21 Watch you teacher combine vinegar and baking soda. What happens? Is some sort of substance being produced?

How can chemical reactions help us extinguish forest fires?

Chapter Summary p. 21 Chemical properties means the ability of a substance to change in a new substance that has different properties. Examples of chemical properties are: flammability and reactivity New substances form as a result of chemical change. A physical change does not alter the identity or make-up of the substance

Section Review p. 21 You are to read and answer the questions from page 21 (1-9). Write your answers in complete sentences. Write the “answers only” for the multiple choice questions.
