  2. Grade 5 Pacing Guide Topic 1: Practicing ScienceBenchmarks • SC.5.P.8.1 Compare and contrast the basic properties of solids, liquids, and gases, such as mass, volume, color, texture, and temperature. • SC.5.N.1.1Define a problem, use appropriate reference materials to support scientific understanding, plan and carry out scientific investigations of various types such as: systematic observations, experiments requiring the identification of variables, collecting and organizing data, interpreting data in charts, tables, and graphics, analyze information, make predictions, and defend conclusions. AA • SC.5.N.2.1 Recognize and explain that science is grounded in empirical observations that are testable; explaining must always be linked with evidence. AA • SC.5.N.2.2 Recognize and explain that when scientific investigations are carried out, the evidence produced by those investigations should be replicable by others. AA • MACC.5.MD.1.2 Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots. For example, given different measurements of liquid in identical beakers, find the amount of liquid each beaker would contain if the total amount in all the beakers were redistributed equally.

  3. Practicing Science:Observing the Natural World of Matter What Is Matter? Matter is the material or “stuff” everything is made of. What are you doing if you are observing matter? Observing matter means to carefully explore all of its properties. Look around the room and identify some matter. What are some physical properties matter can have? Color, texture, odor, shape… What are two properties that all matter share? All matter has mass and takes up space. What are the three states of matter? solid, liquid, and gas

  4. What physical properties doall solids have in common? The particles in solids are close together and vibrate in place. For this reason: • A solid has its own definite shape and definite volume. • A solid keeps its shape even when it moves.

  5. What physical properties do all liquids have in common? The particles in liquidsare not as close together as the particles in solids and move more freely than particles of solids. For this reason: • Liquids have a definite volume. • Liquids take the shape of their container. • Liquids can be poured from one container to another.

  6. What physical properties do all gases have in common? Theparticles in gases move freely in all directions. For this reason: • Gases have no definite size or shape. • Agas take the shape of its container. • A gas will fill all the space inside a container. Three States foldable Three States Venn diagram

  7. Observing and Measuring MatterCenter Choose an Object to Observe Choose an Observation Type List as many properties as you can about that object. What do you observe about that object quantitatively? What are all the things you observe directly about….? Describe how this object looks, feels, sounds, and/or smells. Thumb Pencil Book Desk Chair Penny Drop of Water Rock Shell Plant Leaf Flower Other

  8. Investigation One* • Open up your bag of objects and place them on the tray. • List each object in your notebook as you observe it. • Use your senses to make qualitative observations. Write down words to describe each object. • Use your measurement tools to make quantitative observations and record for each object. • Look over your observation notes and put all the objects that share a property together in one group. Write down the common property. • What word describes the object(s) left over? If more than one do they have a property in common? • Now classify the objects into another group and do steps 5 and 6. *Adapted from abpi Properties of Materials

  9. What are some Properties or characteristics of Matter? Color Shape Size Luster Texture Mass Weight Length Volume State/Phase (solid, liquid or gas)

  10. Investigation Two* Equipment Needed: lab sheet, container of water, flashlight, magnet, circuit (light bulb & wires & battery in a holder connected) Procedures: Read the test below and predict which properties apply to your group’s six objects. Then conduct the following tests using materials provided in order to identify which properties apply to your group’s six objects. Record results on chart. Compare predictions to results. • Does the material change when dipped into water? (absorbent) • Does the material stretch and then return to shape? (elastic) • Does electricity flow when the material is used to complete the circuit? (conductor) 4. Is the magnet attracted to the material? (magnetic) • Can you scratch the material with a fingernail, penny…? (hardness) • Can you see through the material? (translucent -light travels through) • Does the material bend without breaking? (flexible) Bonus: Try to think of a new way to classify your group of objects based on the test results. *Adapted from abpi Properties of Materials

  11. Investigation Two Make predictions, test and then record test results on lab sheet chart. Compare. *Fill in an opposite for each property in the row above.

  12. Match the Properties Being Tested • Does the material stretch and then return to shape? • Does electricity flow when the material is used to complete the circuit? • Is the magnet attracted to the material? • Can a penny scratch the material? • Can you see through the material? • Does the material bend without breaking? • Does the material change when dipped into water? • Absorbent • Elastic • Electrical Conductor • Flexible • Magnetic • Hard • Transparent

  13. What can be added to the Properties of Matter List? Color Shape Size Luster Texture Mass Weight Volume State/Phase (solid, liquid or gas) Flexible Elastic Magnetic Conductor of electricity Ability to sink or float in water Ability to Dissolve in a liquid or solubility

  14. Mystery MATTER(Show What You Know) • Pick a small object that will fit in a paper bag. • Make quantitative observations (mass, length, height, volume…) • Make qualitative observations (texture, luster, flexibility, magnetic …) • Use these observations to write a description including properties that will help others identify this mystery matter. • Share your description with classmates and have them guess what your mystery object is.

  15. MysteryMATTERConnected LearningChoose a mystery object identified and do the following reflection: • Was there a property that helped you determine the mystery object’s identity easier than other properties? Explain. • Which observations were quantitative? • Which observations were qualitative? • What are you wondering now?

  16. Investigation ThreeAdapted from abpi Properties of Materials What do we call characteristics that can be observed, measured, or changed without changing the object itself? physical properties They are the things that do not change about an object unless you change the material. Try out the questions below:

  17. Investigation Four • Choose an object to design. • It could be an umbrella, a sneaker, a backpack or something else. • Think about what property the object needs. For example: an umbrella needs to be waterproof. What else? tough, flexible 4. Decide on what would be a good material. • Draw the design and label the materials to be used and their properties.
