Also known as The International System of Units or the SI System

Length the distance from end to end of an object basic unit = meter use rulers and meter sticks

Approximate Length Measurements (write 2 examples on your paper) Thickness of dime = 1 millimeter Width of a large paper clip or your fingernail = 1 centimeter Width of a doorway = 1 meter Six city blocks or 10 football fields = 1 kilometer 1 mile = 1.6 kilometers

What’s the length of??? 1. Unsharpened pencil: 2. Post-its (longest side): 3. Textbook (longest side):

#2 - Mass the amount of matter in an object basic unit = gram use triple beam balances

Approximate Mass Measurements (write 2 examples on your paper) a grain of salt = 1 milligram a small paper clip = 1 gram 6 apples or 2 pounds = 1 kilogram

What’s the mass of??? 1. Post-its: 2. Empty cup: 3. Cup + 10 pennies:

#6 – Which would be BEST to measure a football field? A. mass in length B. volume in mL C. length in kilometers D. temperature in grams

9/1 Agenda Return Tools & Rules Quiz & NP 3 & 4 TOMORROW! –Check the “no name” bin Benchmark Graphs – due by the end of the day TODAY!!! Can I Chew Gum?? Procedures Correct HW Metrics PPT –Volume & Time notes & activity Today I will answer……What’s the correct measurement?

Look at your ruler ALWAYS use the cm/mm side….. Never inches!!

Look at your ruler 1-30 = centimeters Lines in between = millimeters

Look at your ruler & meterstick Count the lines between 1 & 2 1 cm = 10 mm!

What is the DIFFERENCE in mass from the TBB 1 & 2?

354.6 g – 325 g 29.6 g

#3 - Volume the amount of space (capacity) an object occupies basic unit = liter, cm 3 use graduated cylinders, beakers, and rulers

Approximate Liter Measurements (write 2 examples on your paper) one drop = 1 milliliter 1 liter= half of a 2 liter soda bottle liter bottles of soda = 1 kiloliter

A. Solid Volume basic unit = cm 3 ruler Length x width x height

What’s the volume?? 6 cm x 5 cm x 10 cm = 300 cm 3

What’s the SOLID volume of??? 1. Post-its: _______ cm 3 Length = _____ cm Width = _____ cm Height = _____ cm

B. Liquid Volume basic unit = liter (L) graduated cylinders read the bottom of the meniscus Intervals = 0.1, 0.2, 0.5, 1, 2, 10 mL v=5Jbkk6ndivMhttp:// v=5Jbkk6ndivM

23 23 WHAT? 23 mL

53 53 WHAT? 53 mL

What’s the SOLID volume of??? 1. Post-its: _______ cm 3 Length = _____ cm Width = _____ cm Height = _____ cm

What’s the REGULAR volume of??? 1. Filled cup of water: _______mL

C. Irregular Volume basic unit = 1 mL = 1 cm 3 graduated cylinder Water displacement method Intervals = 0.1, 0.2, 1, 2 or 10 mL

What’s the volume of the rock??  Initial Reading = 200 mL  Final Reading = 260 mL  260 mL – 200 mL = 60 mL  60 mL = 60 cm 3

Water Displacement  Initial Reading of meniscus  4.8 mL  Irregular Object dropped in GC  Read “new” meniscus  5.6 mL  Subtract the “new” from initial reading  Irregular object volume = 0.8 mL  0.8 mL = 0.8 cm 3

What’s the REGULAR volume of???  1. Filled cup of water: _______mL

What’s the IRREGULAR volume of??? 1. Filled cup of water with 2 marbles: _______mL ______ mL = _______ cm 3 3

Time a measure of duration basic unit = seconds

9/2 Agenda Correct procedure rewards – THANK YOU!!! Can I Chew Gum?? Procedures Correct HW Pass back Tools & Rules Quiz Metrics PPT –Volume activity Today I will answer……How do you measure correct measurements?

Time a measure of duration basic unit = seconds

B. Liquid Volume basic unit = liter (L) graduated cylinders read the bottom of the meniscus Intervals = 0.1, 0.2, 0.5, 1, 2, 10 mL v=5Jbkk6ndivMhttp:// v=5Jbkk6ndivM

Intervals of 1 mL 21.5 mL

Intervals of 2 mL 38 mL

Intervals of 2 mL Initial = 50 mL Ending = 52 mL Volume of Spongebob = 2 mL = 2 cm 3

What’s the SOLID volume of??? 1. Post-its: _______ cm 3 Length = _____ cm Width = _____ cm Height = _____ cm

What’s the REGULAR volume of??? 1. Filled cup of water: _______mL
