Learn how to take 2-column notes Begin Unit 1: Measurement Announcements If you do not remember your school email address and password please fill out the sheet on the front table. Thanks! • Homework • Metric Mania Conversion Practice • Complete Student Survey online by Friday. (link on Homework page of my website) SWBAT identify the base unit of measurement for mass, volume, density and length in the metric system.

  2. 6FT 8IN = ? METERS

  3. FTF RULES • You always have to TRY but it’s okay if you don’t get it right. • Write the DATE. • Write a brief description of what the activity is. (you do not need to copy the directions word for word – these are quick activities). • Always number or letter the answers (if more than one!) • You can have more than one FTF per page. Just be sure to date them! • I sometimes collect them to count as a homework or class work grade.

  4. Expectations for Our Classroom • Be Nice • Be Honest • Be Respectful • Be Prepared • Be Your Best, Always! BACK

  5. Classroom Procedure In addition to what’s written in the welcome letter: • Raise your hand if you wish to speak. • Raise your hand if you wish to leave your seat. (1 finger means bathroom, 2 fingers means pencil sharpen/other, full hand means question or answer). • Keep hands, feet, and objects to yourself. • Keep on task! • Push in your chair when you leave! • My job is to teach you. Not pick up your trash. So throw things away! • This is a working classroom. I always do my best to teach you, and you should always do your best to learn. BACK

  6. GROCERY STORE SORT • You have 20 items. • Cut them apart. • Group the cards together into categories that you think make sense. • Lay them out on your table in the categories • NO NEED TO WRITE ANYTHING DOWN!

  11. TODAY’S AGENDA 9/5 FTF Metrics in the U.S. Make a list of all the metric measurements you can find on the U.S. labels (grab a label from the white dish pans distributed around the room). TODAY IN SCIENCE CLASS FTF Begin Unit 1: Measurement Conversion War Game Announcements Happy Friday! • Homework • Metric Mania Conversion Practice • Complete Student Survey online by Friday. (link on Homework page of my website) SWBAT identify the base unit of measurement for mass, volume, density and length in the metric system.

  12. SYSTEMS OF MEASUREMENT(HINT: USUALLY THE HEADING UP HERE MAKES A GOOD “MAIN IDEA” FOR YOUR NOTES) • There are multiple units of measurement • In the U.S. we use the English System or Customary System • Most of the world uses the Metric System Can you think of the units we use in the U.S. to measure • Liquid • Mass • Length • Temperature • Time • Write them on your whiteboard

  13. METRIC SYSTEM(HINT: USUALLY THE HEADING UP HERE MAKES A GOOD “MAIN IDEA” FOR YOUR NOTES • The metric system is a system of measurement that is used by scientists all over the world. • In the science world it is also called it “System International” or SI. Can you think of the metric units used to measure • Liquid • Mass • Length • Temperature • Time • Write them on the white board!

  14. METRIC BASE UNITS • Liquid = Liters • Mass = Gram • Length = Meters • Temperature = Celsius • Time = Seconds

  15. LENGTH • The distance between two points. • Base unit is the meter (abbreviated with a lowercase m)

  16. MASS • The measure of the amount of matter an object contains • Matter: The material that all objects and substances are made up of • Anything that has mass and takes up space is matter • Base unit of mass is the gram (abbreviate with a lowercase g)

  17. VOLUME • The amount of space an object takes up. • Measure in L (liters) for liquid. • Measured in cm3 for solids

  18. DENSITY • The measure of mass per given volume. • d = m / v

  19. MASS & VOLUME & DENSITY OF BOTTLES

  20. TODAY’S AGENDA 9/8 FTF 1. In your notebook list the base unit for mass, volume, length. Include the abbreviation. 2. What “hint” can you use to remember the formula for density? TODAY IN SCIENCE CLASS FTF Begin Unit 1: Measurement Conversion War Game Announcements Conversion Quiz Thursday! • Homework • Metric Mania Conversion Practice SWBAT correctly convert between metric measurements by converting to 3 larger units and 3 smaller units.

  21. METRIC PREFIXES • Prefixes are added to metric units to indicate smaller or larger units of measurement. • Units larger than the base unit are kilo, deca and hecto • Units smaller than the base unit are deci, centi and milli. • Prefixes also have abbreviations.

  22. Copy A Ladder Like This In Your Notes! (or tape the printed version into your notes) BASE

  23. Add the Prefixes in the Correct Location! BASE WORD BANK CENTI KILO DEKA DECI MILLI HECTO

  24. Add the Prefix value in the Correct Location 1000 UNITS 100 UNITS 10 UNITS BASE METER GRAM LITER 0.1 UNITS 0.01 UNITS 0.001 UNITS

  25. Add the prefix abbreviation to your ladder. This Is What Your Final Ladder Should Look Like! 1000 UNITS Kilo (k) 100 UNITS Hecto (h) 10 UNITS Deka (dk) BASE METER GRAM LITER 0.1 UNITS Deci (d) 0.01 UNITS Centi (c) 0.001 UNITS Milli (m)

  26. CONVERTING METRICS: STAIRCASE METHOD 1000 UNITS kilo To convert to a smaller unit, move the decimal point to the right or multiply. 100 UNITS hecto 10 UNITS deka BASE METER GRAM LITER 0.1 UNITS deci 0.01 UNITS To convert to a larger unit, move the decimal point to the left or divide. centi 0.001 UNITS milli WORD BANK CENTI KILO DEKA DECI MILLI HECTO

  27. GRAB A WHITEBOARD!LET’S PLAY BIGGER OR SMALLER(WRITE YOUR ANSWER ON THE WHITEBOARD) • Which prefix indicates a larger measurement? • kilo or centi • deci or deka • centi or milli • Which prefix indicates a smaller measurement? • milli or hecto • centi or deci • deka or kilo

  28. PRACTICE ABBREVIATING • Abbreviate: • Kilogram • Dekaliter • Hectometer • Milligram • Centimeter • Decigram • Reverse It • mm • cL • kg • dkm • hg • cm

  29. CONVERTING UNITS • To convert to a larger unit, move the decimal point to the left or divide. • To convert to a smaller unit, move the decimal point to the right or multiply. • Khan Academy Video Link

  30. TODAY’S AGENDA 9/9 FTF (Homework Out Please!) 1. With your partner, make a “ladder” out of the metric prefix cards. (In envelope) 2. Place the value card next to the correct prefix. TODAY IN SCIENCE CLASS FTF Review Homework Metric Conversion – Division/Multiply Conversion Card Game Announcements Conversion Quiz Thursday! • Homework • Why Does Lighting Strike? Conversion Worksheet (Both Sides!) SWBAT correctly convert between metric measurements by converting to 3 larger units and 3 smaller units.

  31. Add the prefix abbreviation to your ladder. This Is What Your Final Ladder Should Look Like! Kilo (k) Hecto (h) Deka (dk) BASE METER GRAM LITER Deci (d) Centi (c) Milli (m)

  32. CONVERTING USING MULTIPLICATION OR DIVISION • Metric prefixes are based on 10. • Each prefix is 10 times greater or 10 times less than the prefix on either side. • To convert using multiplication or division: • Determine starting prefix. • Figure out how many times greater or smaller the prefix is that you are converting to. • Multiple or divide depending on if you are converting to a larger prefix or smaller prefix.

  33. REMEMBER!DO A REALITY CHECK AFTER A CONVERSION • If you are converting from a large unit to a smaller unit your answer should be a larger number than the original measurement. • Example: kilometer to meter • .05 km = 50m • 10 km = 10 000m • If you are converting from a small unit to a large unit, your answer should be a smaller number than the original measurement. • Example: mL to L • 5 000mL = 5 L • .15 L = 150 kL

  34. LET’S PRACTICE • How many milliliters are in 1 liter? • Ask: home many times bigger/smaller is a milliliter compared to a liter. • Decide: will I multiply or divide my starting number? • Do the math. • Convert 360 cm to dkm • Convert .06km to m

  35. TICKET OUT! • 5 500 km = ______________ m ? • .05 g = ________________ kg? • 5000 mL = ____________ L?

  39. ADDING AND SUBTRACTING METRIC PREFIXES Sometimes we have measurements we need to add but they are not measured in the same unit. Problem: 300g + 3kg = ____ g Rules for Solving • Convert all numbers to the unit of the answer. • Rewrite the problem with converted values. • Add or subtract the converted numbers to solve problem. Example: • Answer should be in grams • Convert 3 kg to 3 000 g • 300 g + 3 000 g = 3 300g

  40. METRIC MATH PRACTICE Addition • 1000 mL + 5 L = _________ L • 5 km + 39 m = ___________ m • 9 800g + 1 kg = __________ g Subtraction • 8 L – 2500 mL = ________ mL • 62 kg – 1000 g = ________ g • 25 km – 5000 m = ______ km ANSWERS • 6 L • 5 039 m • 10 800 g Subtraction • 5 500 mL • 61 000 g • 20 km

  41. Solving for an unknown value PROBLEM: 1 500 cm = 50cm _______cm Rules for Solving • Rewrite problem substituting x for unknown (do not drop the prefix!) • Apply apply math rules to solve for unknown value. Example 1 500 cm = 50cm + x cm Subtract 50cm from both sides 1 500 cm – 50 cm = x cm 1 450 cm =x

  42. Solving for an unknown value with mixed prefixes PROBLEM: 5 500 cm = 50m _______cm Rules for Solving • Convert all numbers to the same unit as what the answer should be in. • Re-write problem with converted measurements. • Apply apply math rules to solve for unknown value. • Example • 50 m = 5 000 cm • 5 500 cm = 5 000cm + ___?_____ cm • Subtract 5 000 from both sides • 5 500 cm – 5 000cm = 500 cm • Answer = 500 cm • Practice: #9 on crossword • 7 000 mm 511 cm = 12 m _____cm
