3. Experimental measurements must not only be RELIABLE and ACCURATE but also must be easily understood by others

4. a decimal system of measurement based on 10 Units of SI used in this class: Kilo= 1,000 centi= 1/100 or.01 deci= 1/10 or.1 milli= 1/1,000 or.001

5. When Measuring…Use… length meters (m) volume (l x w x h) liter (L) mass grams (g) temperature Celsius (°C) *Mass is a measure of amount of matter in an object. *Weight is measure of gravitational force

6. centimeter millimeter 1 meter=100 centimeters (cm) 1 meter= 1000 millimeters (mm) 1 cm= 10mm

18. is the mass of an object per unit volume (D=m/v). The unit for density is a combination of more than one fundamental unit and is therefore called a derived unit

19. The density of water is 1.0 g/mL If an object’s density is greater than 1.0 g/mL will it sink or float? http://www.explorelearning.com/index.cfm?method=cResource.dspV iew&ResourceID=17
