2. Units Length- meters (m) Volume (space)- liter (l) Mass (similar to weight)- grams (g)

7. Conversions To go up the steps, move the decimal to the left the number of steps you are going. To go down the steps, move the decimal to the right the number of steps you are going.

8. Group Practice

9. How much space an object takes up Three types: Regular solids, Liquids, and Irregular solids

10. Volume of Regular Solids Use the metric side of a ruler! = length x width x height = m x m x m = m 3 = cm x cm x cm = cm 3

11. Volume of Liquids Use graduated cylinder Read bottom of curve (meniscus) Unit- liter = L (about a quart) 1 mL = 1 cm 3

12. Volume of Irregular Objects Use displacement How much water level increases when dropped in a graduated cylinder How much space it holds

13. Mass- amount of matter in the object (how many particles) Use a triple-beam balance or a scale. Unit= Gram (about the mass of a paper clip)

14. Temperature Use a Celsius Thermometer Measure in the middle of a liquid Unit= Degree (C) 100 C- water boils (212 F) 21 C- room temperature (about 72 F) 0 C- water freezes (32 F) -273 C- “absolute zero” (-460 F) Particle motion stops!
