1. Quantitative Observations/Data Measurements

2. Base Units in the SI System Length:________ Volume:_________ Mass:________ Temperature:__________ Meter (m) Liter (L) Gram (g) Celsius (C)

3. Prefixes in the SI System Kilo: __________________ Example: 1 kilometer = 1000 meters Deci: __________________ Example: 1 decimeter = 0.1 meters Centi: _________________ Example: 1 centimeter = 0.01 meters Milli: __________________ Example: 1 millimeter = 0.001 meters Micro: _________________ Example: 1 micrometer = 0.000 001 meters Nano: _________________ Example: 1 nanometer = 0.000 000 001 meters 10 3, (K) 10 -1, (d) 10 -2, (c) 10 -3, (m) 10 -6, (µ) 10 -9, (n)

4. Ways to Measure Length: ____________________________ Mass: _____________________ OR ____________________ Temperature: ________________ Volume of a Liquid: _______________________ – Remember to ALWAYS read from the __________________________ Centimeter Ruler or Meter Stick Triple beam balanceElectric balance Thermometer Graduated Cylinder Bottom of the meniscus

5. Ways to Measure continued… Volume of an Irregular Solid: 1) Pour liquid into the cylinder and measure volume, record this as the before volume _______ 2) THEN put your object into the cylinder and measure volume, record this as the after volume _______ 3) Subtract the volume of the water (before volume) FROM the volume of the water + the object (after volume). ___________ - _____________ = ________________ 4) You now have the volume of an irregular object Volume of a Solid: Measure Length, Width, and Height and then use the formula below Formula: _______________________________________________ Volume = Length x Width x Height
