2Benchmark Descriptions SC.4.P.8.1 – Measure and compare objects and materials based on their physical properties including: mass, shape, volume, color, hardness, texture, odor, taste, and attraction to magnets.SC.4.P.8.2 – Identify properties and common uses of water in each of its states.
3What is matter?Matter is everything around you, including you!Matter is what all things are made of.
4Solids A solid has its own shape. A solid does not change unless you cut, bend, or break it.Solids take up space and have mass.
5Liquids Liquids do not have their own shape. Liquids take the shape of their container.Liquids take up space and have mass.
6Gases Gases have no definite size or shape. Gases take the shape of its container.A gas will fill all the space inside a container.Gases take up space and have mass.
7Water is matter. Did you know it comes in all 3 forms? A SolidA LiquidA Gaswater vaporwaterice
8Matter has certain properties. Properties are the characteristics of matter, how something looks or feels.Matter can have color.Matter can be different sizes.Matter can have different shapes.Matter can have texture.Matter can be rigid or bendable.Matter also takes up space and has mass.
10Solid Liquid Gas Has definite shape Particles are close together and slow movingHas volume
11Solid Liquid Gas Has a definite shape Takes on shape of container Particles are close together and slow movingParticles are farther apart and faster-movingHas volume
12Solid Liquid Gas Has a definite shape Takes on shape of container Does not have definite shapeParticles are close together and move slowlyParticles are farther apart and faster movingParticles are farthest apart and move rapidlyHas volumeExpands to take up whatever space is available
14Review Questions1. What are the 3 forms of matter? Solids, Liquids and Gases 2. A solid has a definite shape. True or False True 3. A liquid has a definite shape. True or False False. A liquid has a definite size, but it takes the shape of its container. 4. A gas has a definite shape. True or False False. A gas has no definite size or shape, because it fills all the space of its container. 5. What are some properties of matter? color, size, shape, texture, odor, attraction to magnets, mass, hardness, taste, and volume
15Physical Properties of Matter Qualitative vs. Quantitative
16Qualitative Five Senses Sight - Looks Touch - Feels Hearing – Sounds when moving…Odor – SmellsTastes
19A second property is size. Small objectsSizeLarge objects
20A third property is shape. SquaresTrianglesCirclesShape
21We can group objects if they are rigid or bendable. Bendable means that the matter can bend, curve, or turn.Rigid means that the matter cannot bend, it is stiff.Can you name something that is rigid and something that is bendable?
22Which objects are rigid? Which objects are bendable?
23These objects are rigid. These objects are bendable.
31Game Rules Games Rules Name of Matter? Select an object from the tray. List the both qualitative and quantitative properties (begin with the most obvious properties).Use your five senses to identify the qualitative properties.Use the appropriate measurement tools to discover quantitative properties.Give descriptions to other group as they try to guess the object based on the properties.Qualitative: Sink/Float?Attracted to a Magnet?Other observations that will help identify this matter (use your five senses).Quantitative: Mass? Volume? Linear Measure?
33Big Idea 8: Properties of Matter SC. 4. P. 8 Big Idea 8: Properties of Matter SC.4.P.8.2 – Identify properties and common uses of water in each of its states.Keisha Kidd, Curriculum Support SpecialistMary Tweedy, Curriculum Support SpecialistMillard Lightburn, PHD Instructional SupervisorPacing Guide – Quarter 1 Topic 4 09/16-09/27Department of Mathematics and ScienceOffice of Academics and Transformation
34Benchmark Essential Content Understand phase changes as they relate to water.Recognize the properties of water and water’s common uses.Identify the properties of water.
35Let’s Explore!Adapted from Inquiry in Action Chapter 6
41Physical change-a change in state The substance is still the same substanceForm changes but chemical makeup doesn’t
42Ice changes to water—water changes to ice, frozen water is still water
43Water changes to steam, a gas, when it is heated to its boiling point,water vapor condenses to form a liquid
44Changing States of Matter-Water Water freezes at 0 degrees Celsius, 32 degrees FahrenheitWater boils at 100 degrees Celsius, 212 degrees Fahrenheit
45Properties of WaterWater is unique in that it is the only natural substance that is found in all three states -- liquid, solid (ice), and gas (steam) on Earth.Water as a liquid is sticky and elastic, and tends to clump together in drops rather than spread out in a thin film.Water as a solid (ice) is less dense than liquid water and floats on it.Water changes state when enough heat or thermal energy is added to it or removed from it.Water changing one from state to another is an example of a physical change.Water freezes at 32o Fahrenheit (F) and 0o on the Celsius scale.Water boils at 212o F and 100o on the Celsius scale.
46Big Idea 8: Properties of Matter SC. 4. P. 8 Big Idea 8: Properties of Matter SC.4.P.8.3 – Explore the law of conservation of mass by demonstrating that the mass of a whole object is always the same as the sum of the masses of its parts.
47Conservation of Matter Chemical changes don’t make new matterThe total mass of the products that form equals the total mass of the substances that react.

49SC.4.P.8.4 – Magnetic Properties Investigate and describe that magnets can attract magnetic materials and attract and repel other magnets.
50William Gilbert, an English physician, first proposed in 1600 that the Earth itself is a magnet, and he predicted that the Earth would be found to have magnetic poles.Engage: Story slide 2:Do magnetism cloze activity.
51VocabularyAttract To pull toward one another, as opposite poles of two magnets pull toward one another.Force A push or a pull.Magnetism A property of certain kinds of materials that causes them to attract iron or steel.Repel To push away, as similar poles of two magnets push away from one another.Pole Either of two opposing forces or parts, such as the poles of a magnet.
52What is Magnetism?Magnetism is the force of attraction or repulsion of a magnetic material due to the arrangement of its atoms.Explain
53Defined by: http://science.howstuffworks.com/magnet.htm Magnet BasicsMagnets are objects that produce magnetic fields and attract metals like iron, nickel and cobalt.The magnetic field's lines of force exit the magnet from its north pole and enter its south pole.Some magnets occur in nature, they are called natural magnets.ex. magnetite (also called lodestone)Defined by:
54Magnetism Magnetism is a force. Magnets have different strengths Metals stick to magnetsMagnets have different strengthsMagnets have two poles:north and southLike Poles repelOpposite poles attractThe force of magnetism can travelthrough some objects.ExplainStudents share reflections: What do you know aboutmagnetism now?
55The Earth is a magnet:Geographic North PoleIt exerts magnetic forces and is surrounded by amagnetic field that is strongest near the North and Southmagnetic poles.Magnetic South PoleExtend/ElaborateGeographic South PoleMagnetic North Pole
56The ends of a magnet are where the magnetic effect is the strongest The ends of a magnet are where the magnetic effect is the strongest. These are called “poles.” Each magnet has 2 poles – 1 north, 1 south.Explain
58Properties of Magnets Like magnetic poles repel each other. Unlike magnetic poles attract each other.Not all objects are affected by the force of magnetismex. wood, glass, paper, plasticCommon metals affected by magnetism are iron, nickel, and cobalt
59Let’s Explore What happens if you put together two magnets? Do they become stronger together?Experiment with magnets, a variety of sizes of magnetic objects, and write observations about strengths of different combinations of magnets.
61Exploring Magnetism Stations: An Absolutely Magnetic Experience! Station #1 Which Objects are Magnetic?Station #2 Can you Fish?Station #3 Can Magnets Float?Station #4 Can you Play Marbles?Station #5 Are all Magnets the Same?Station #6 How can you Define a Magnetic Field?Reflection:What do you know about magnetism now?Explore magnetic concepts through the stations.Explain: Students share what they did and learned from each station. Then they reflect: What do you know aboutmagnetism now? See next slide.
