  1. OBJ 1: Name & describe the 2 properties of all matter. OBJ 2: Compare mass with weight. Warm-up: Turn in last night’s hw. Place it in your class bin. Homework: 1- Read & take notes on pgs 4-10. Answer Section Review questions. Science in the News# 1 due 9/5 What’s the Matter? • 9/4/14

  2. Matter is … EVERYTHING Almost…

  3. What is matter? (Specifically) Anything that has mass and takes up space. What does this mean?

  4. We know matter comes in … ? *5 States http://www.chem4kids.com/files/matter_intro.html What is the 5th state? Research. Go find out!

  5. There are 2 properties of matter • Volume: • the amount of space taken up by an object • Mass: • the amount of matter that something is made of

  6. In science… We primarily measure volume in milliliters, liters (liquids), cubic centimeters (cm^3). . . Other types of volume measurements:

  7. Measuring liquid volume Meniscus: the curve at a liquid’s surface by which you measure the volume of a liquid

  8. Measuring solid volume- a regular shape Length x width x height

  9. Calculate What is the volume of a cube that is 2cm x 4 cm x 8 cm?

  10. Measuring solid volume- an irregular shape

  11. What displacement 1. First fill a graduated cylinder with a given amount of water 2. Be sure to measure the liquid. 3. Next place the object in the cylinder and record the rise in water level. 4. To find the volume subtract.

  12. Conclusion Why does matter have to have volume?

  13. OBJ 1 & 2. See previous day’s notes. Warm-up: 1. What are the 2 properties of all matter? 2. How is volume measured? 3. Do objects with large masses always have large weights? Explain your reasoning. What’s the Matter? Homework: 1- Study notes 2- read through Volume Lab on page 132. 3-Science in the News# 2 due 9/12 • 9/5/14

  14. Agenda • Review notes • QUIZ • What is matter? • Units of measure • Calculating volume of a… • Liquid • Solid • Irregular solid • Measuring instruments • Recap of states of matter

  15. Is air matter? • Does air have mass? Volume? • How can I prove that air is matter? Think about it! You tell me!

  16. Does Air Have Mass? Option 1: In your notebook, write this question and then state your hypothesis. • Weigh (with a balance) a deflated balloon. Record results in notebook. • Inflate that same balloon and weigh (with a balance). Record results in notebook. • Do your results support your hypothesis? Why or why not?

  17. Weight or mass? • When you measured the balloon, did you measure its weight or mass? Let’s see the difference. Weight in pounds: “Weight” (mass) in grams: • Quiz ?!

  18. Does air take up space? Option 2: Procedures: • Crumble a piece of paper into the cup making sure that it will not fall out. • Turn the cup straight upside down and submerge it into a container of water. • Record your observations. • Punch a small hole in the cup & repeat the same procedure. • Do your observations support your hypothesis? Why or why not?

  19. Is Mass the same as Weight? • NO. • Mass • Measure of the amount of matter in an object • ALWAYS CONSTANT no matter where you are in the universe • Measured with a balance • Expressed in kilograms Weight 1. Measure of GRAVITATIONAL FORCE on an object 2. Varies, depending on the distance to Earth or other large body 3. Measured with a spring scale 4. Expressed in Newtons

  20. To Visualize it. . . Mass Weight • $$$ • g • kg Text >

  21. What is gravity? • Gravity is a force of attraction between objects that is due to their masses. This attraction causes objects to exert a pull on other objects. • All matter has mass, and all matter experiences gravity • The amount of attraction between objects depends on 2 things: • The masses of the objects • The distance between them

  22. Spoof on Newton’s law of Universal Gravitation http://www.youtube.com/watch?v=jwPc0kK9VHU&feature=related In … • Pounds? • Newtons? • 1 pound force = 4.44822162 newtons How much do you weigh?

  23. MultipleAnswer: 543 N or Newtons 4.45 N X 120 lb = ? 4.45 X 120 8900 + 44500 534.00

  24. What do you think…about gravity? See if you can answer the questions on the following slide.

  25. More about Gravity. . . • As distance between 2 objects decreases. . . The gravitational force between the 2 objects (increases/decreases) • As distance between 2 objects increases. . . The gravitational force between the 2 objects (increases / decreases) • The mass of Object A decreases. The gravitational force between Object A and Object B (increases / decreases) • The mass of Object A increases. The gravitational force between Object A and Object B (increases / decreases)

  26. Understanding mass and gravity Homework. What is the difference between weight and mass? Conclusion:

  27. OBJ 2A: Calculating volume. Monday, Sept. 8th • Warm-up: Lab prep!
