  1. Warm-up 9/3/13 • What is Matter? • List 10 things that are matter. • What is mass? • What is volume?

  2. Essential Questions: What is intensive and extensive properties?Look in book Warm-up • What is the formula for density? Do you know the formula triangle? • What are mass and volume? D = m/v

  3. Essential Questions: What is intensive and extensive properties?Look in book • Examples of intensive- • Examples of extensive- Density, hardness,BP,MP Mass,volume, weight

  4. Pre-lab What is the formula for calculating volume of cylinder? How do we calculate the volume of irregularly shaped object? V= r2h Water displacement Eureka!!!

  5. Warm-up • Convert the following to scientific notation • 0.0000355 3) 20,000,000,000 2) 3549848 4) 0.0002300 Convert 5) 12,000 millimeters to meters 6) 3.00 X 10 5 meters to kilometers 7) .0086meters to centimeters

  6. Density Lab 9/3/13What is each cylinder made of? 4 different types of cylinder use formula for cylinder to calculate volume of silver and gold use water displacement to calculate volume of black and white plastic measure mass of all on balance

  7. Unit Essential Question: What is density?Daily EQ: Can we graph density? Warm-up 9/4/13 • The slope of the mass vs. volume graph is equal to what? • When graphing mass vs. volume who is on what axis? • What are physical and chemical changes? To do Lab report write up due Friday 2/1

  8. TOD 9/4/13 • Define the following • 1) intensive property • 2) example of intensive • 3) extensive property • 4) example of extensive • 5) Accuracy - • Write in scientific notations 6) 236,000 = 7) 0.000056 8) What is the density of an unknown liquid if 34.8 grams occupies 12mL? (Include units)

  9. Essential Question: What are pennies made of? How can we use density to help us find out? Select 10 pennies from each container and make sure to separate 10 1982 and before.

  10. Density Problems • If 25.6 grams of a substance has a volume of 5.7 mL, what is the substance? How do I know how to round it off? • What mass of aluminum occupies 18.98cm3 ? 25.6 g = 4.49122807 = 4.5 to sig figs 5.7mL Use yellow packet find density of aluminum D = m/v 2.702g/ml = m/18.98cm3 m = 51.28 grams

  11. Unit Essential Question: What is density?Daily EQ: Can we graph density? Warm-up 9/4/13 1) What is the density of 78 grams of aluminum that has a volume of 28.87mL? 2) How many grams of gold were found in the ship wreck if it occupied 435cm3 of space (density of gold is 19.31 g/cm3) ?

  12. Penny Lab 1) Select 10 Pre-82 pennies and 10 ‘83 and newer 2) Determine the density of each set of pennies. You can use either method to determine volume. 3) Find the metal on page R-47 through R-49 Make sure it sounds like a reasonable metal 4) What other physical or chemical properties could we use to make the final distinction

  13. States of matter 9/5/13 • What is the difference between solid, liquid and gas? • List as many characteristics of each in columns • Draw a sketch of each. Small and simple • Hamburger - remember

  14. We’ve got Gas Laws §Properties of gases No definite shape  Take shape of container §      No definite volume §      Compressible  Particles are spaced out more than any other state of matter §      Fluid §      Low density §

  15. RetakeTicket in the door • Convert the following to scientific notation • 0.000000355 3) 20,000,000, 2) 3549 4) 0.0002300 Convert 5) 12,000 centimeters to meters 6) 3.00 X 10 3 meters to kilometers 7) .00086meters to centimeters

  16. To do • Make sure you have a book • Look over chapter 3 and make sure you know all vocab • Get yellow packet! • Finish and present All about Me!
