1. Monday, August 31, 2009 Record your homework immediately. TODAY is the final day for turning in your Safety Contract and signing Class Procedures (electronically). Any student not turning in these documents by today will earn detention until the missing documents are submitted. Unpack notebook, calculator, and writing utensil. Each table will need a pair of scissors, a metric ruler and tape. You do NOT have to sign in today.

2. Measurement (review) –What does “SI” mean? –What is the standard unit used for measuring length? –What is the most commonly used unit for measuring mass? –In what unit would the volume of a container of milk be measured? –In what unit would the volume of soil for a garden be measured? –Of the four common phases of matter, which is considered a fluid?

3. What is volume? …the amount of space something takes up regular objects – use formula l x w x h = units 3 Your cube?

4. What is volume? …the amount of space something takes up regular objects – use formula l x w x h = units 3 irregular objects – use water displacement Water displacement works because 1 mL = 1 cm 3 How much water will fit in your cube?

5. What is mass? …the amount of matter something contains

6. Our 1 cm 3 volume cube holds 1 mL of WATER and has a mass of: 1 gram. Write a sentence in your own words that describes this relationship between solid and liquid volume and mass within the metric system.

7. d is the object's density (sometimes a p is used instead of a d) m is the object's total mass (standard = measured in kilograms)mass V is the object's total volume (standard = measured in cubic meters)volume The SI unit (metric) of density is the kilogram per cubic meter (kg/m 3 ). We will usually measure volume in smaller units, such as grams and cubic centimeters making the unit g/cm 3.SIkilogram per cubic metekgm 3 how much mass is packed into an object’s volume d = m / V What is density?

8. Which object would have a higher density? Mass 7295 grams Volume 5422 cm 3 Mass 5300 grams Volume 5422 cm 3 D=M/V or D = 7295 g/5422 cm 3 = 1.34 g/cm 3 (a sinker) D = m/V D = 7295 g/5422 cm 3 = 1.34 g/cm 3 D = m/V D = 5300 g/5422 cm 3 = 0.98 g/cm 3 Will these two objects sink or float in water? Why? What if I told you they were both bowling balls?bowling balls Distilled water has a density of 1 g/cm 3.

10. Copy the data table into your notebook. Update your Table of Contents. As I go over each event, use INK to record an estimate of how you will perform. You will need an accountability partner. Be sure to put their name in your notebook. Competition will be tomorrow.
