  1. Materials: -PRIDE Card -IN -Pencil/Pen What is a counselor? A counselor is a person trained to give guidance on personal, social, or psychological problems. 2. What does a school counselor do? Counselors help all students in the areas of academic achievement, personal/social development and career development, ensuring today's students become the productive, well-adjusted adults of tomorrow 3. Who is our counselor here at the “Soss”? Ms. Morgan Bellwork 8/14/14

  2. Let’s go over the Pre-test

  3. Metric System

  4. Update your Table of Contents!! ?? 8/14/14 The Metric System

  5. Bill Nye – Measurements and the Metric System Video http://www.cleanvideosearch.com/media/action/yt/watch?v=_E53TKNVH0c

  6. Materials: -PRIDE Card -IN -Pencil/Pen 1. Create a circle map showing things that need to be measured. Ingredients to make chocolate chip cookies Measurement Bellwork 8/15/14 Minimum of 15!!

  7. Glue in Target Test bubbles to the back page of your IN. • Write in Learning Target 1 • Fill in Bubble with TT1 score  Learning targets and target test tracking!

  8. Learning Targets Target Tests 1. Identify the function of materials we use in the science lab.

  9. Materials: -PRIDE Card -IN -Pencil/Pen List 5 things from your circle map (example: distance from your house to school) What units would you use to measure each of the above items? Bellwork8/18/14

  10. How do YOU measure things?

  11. What UNITS do you use to measure? We are going to learn a new measurement language! English vs. Metric!

  12. The International System • Abbreviated “SI” from the French phrase: Le Système international d'unités • It is the world's most widely used system of measurement. • AKA the Metric System!

  13. Metric System Length Mass Volume Meters (m) Grams (g) Liters (L)

  14. Prefix vs. Suffix • The suffix is the root word • It always comes after the prefix. • Example: multivitamin – “multi” is the prefix and “vitamin” is the suffix • Prefixes by themselves don’t mean anything. • Example, the prefix “Un” means nothing • Added to unhappy means not happy.

  15. These are the Suffixes…. Metric System Length Mass Volume Meters (m) Grams (g) Liters (L)

  16. Metric Prefixes • Kilo (k) – largest • Hecto (h) • Deca (da) • BASIC UNIT!! • Deci (d) • Centi (c) • Milli (m) – smallest • They will never be by themselves, they have to be written with a suffix.

  17. Why do we have specific prefixes for each type of measurement… Length A big measurement A small one Km mm

  18. Same scenario works for volume and mass • Volume – what units (prefix + suffix) would you use to measure the volume of this?_______ • Mass - what units (prefix + suffix) would you use to measure the mass of this?_________

  19. Quick Quiz What units (prefix + suffix) would you use to measure…. 1. 2. 3.

  20. Lesson 1: Length Turn to a new page!!

  21. 1 mile 1.6 kilometers 1 yard = 0.9444 meters 1 inch = 2.54 centimeters English vs. Metric Units Which is longer? A. 1 mile or 1 kilometer B. 1 yard or 1 meter C. 1 inch or 1 centimeter Left Image: http://webapps.lsa.umich.edu/physics/demolab/controls/imagedemosm.aspx?picid=1167Right Image: http://share.lancealan.com/N800%20ruler.jpg

  22. A. 1 meter or 105 centimeters B. 4 kilometers or 4400 meters C. 12 centimeters or 102 millimeters D. 1200 millimeters or 1 meter km Metric Units m cm mm The basic unit of length in the metric system in the meter and is represented by a lowercase m. Metric Units 1 Kilometer (km) = 1000 meters 1 Meter = 100 Centimeters (cm) 1 Meter = 1000 Millimeters (mm) Which is larger?

  23. 1 centimeter = 10 millimeters What is the length of the line in centimeters? _______cm What is the length of the line in millimeters? _______mm Measuring Length How many millimeters are in 1 centimeter? 2.8 28

  24. Making Accurate Metric Measurements Always (MAMMA) • You have been hired on by the esteemed company MAMMA. • Your job is to accurately measure and weigh anything and everything in front of you! • If you are able to complete the following tasks you will be promoted to chemist (which is a necessity to continue further in Miss Miks’ class!!) • Three parts: • Length • Mass • Volume • Good luck and happy measuring!

  25. Lesson 2: Mass Turn to a new page!!

  26. 1 pound = 453.6 grams 1 ounce of gold = 28,349.5 milligrams 100 kilogram = 220 pounds English vs. Metric Units Which is larger? 1. 1 Pound or 100 Grams 2. 1 Kilogram or 1 Pound 3. 1 Ounce or 1000 Milligrams

  27. A. 1 kilogram or 1500 grams B. 1200 milligrams or 1 gram C. 12 milligrams or 12 kilograms D. 4 kilograms or 4500 grams kg Metric Units cg mg g Mass refers to the amount of matter in an object. The base unit of mass in the metric system in the kilogram and is represented by kg. Metric Units 1 Kilogram (km) = 1000 Grams (g) 1 Gram (g) = 1000 Milligrams (mg) Which is larger? Kilogram Prototype Image - http://en.wikipedia.org/wiki/Kilogram

  28. Once you have balanced the scale, you add up the amounts on each beam to find the total mass. What would be the mass of the object measured in the picture? _______ + ______ + _______ = ________ g Measuring Mass We will be using triple-beam balances to find the mass of various objects. The objects are placed on the scale and then you move the weights on the beams until you get the lines on the right-side of the scale to match up. 70g 300g 373.35 3.35g Let’s put out knowledge to work in the lab!

  29. Lesson 3: Volume Turn to a new page!!

  30. 1 fl oz = 29.573 ml 1 12-oz can of soda would equal approximately 355 ml. 1 quart = 0.946 liters 1 gallon = 3.79 liters It would take approximately 3 ¾ 1-liter bottles to equal a gallon. English vs. Metric Units Which is larger? A. 1 liter or 1 gallon B. 1 liter or 1 quart C. 1 milliliter or 1 fluid ounce

  31. kL Metric Units cL mL L Volume is the amount of space an object takes up. The base unit of volume in the metric system in the liter and is represented by L or l. Metric Units 1 liter (L) = 1000 milliliters (mL) 1 milliliter (mL) = 1 cm3 (or cc) = 1 gram* Which is larger? A. 1 liter or 1500 milliliters B. 200 milliliters or 1.2 liters C. 12 cm3 or 1.2 milliliters*

  32. What causes the meniscus? A concave meniscus occurs when the molecules of the liquid attract those of the container. The glass attracts the water on the sides. Measuring Volume We will be using graduated cylinders to find the volume of liquids and other objects. Read the measurement based on the bottom of the meniscus or curve. When using a real cylinder, make sure you are eye-level with the level of the water. What is the volume of water in the cylinder? _____mL 43

  33. Measuring Liquid Volume What is the volume of water in each cylinder? 37mL 52mL 23mL A B C Pay attention to the scales for each cylinder.

  34. 9 cm 8 cm 10 cm We can measure the volume of irregular object using water displacement. Amount of H2O with object = ______About of H2O without object = ______Difference = Volume = ______ Measuring Solid Volume We can measure the volume of regular object using the formula length x width x height. 10cm 8cm 720cm3 _____ X _____ X _____ = _____ 9cm 1 mL = 1 cm3 260cm3 200cm3 60cm3 Let’s put out knowledge to work in the lab!

  35. Lesson 5: Unit Conversions

  36. Great… How do I do conversions?

  37. How do I remember the order?? OR… • Kids • Have • Damaged • 3 • Different • Colorful • Millipedes

  38. Example #1: 0.250kg mg The decimal is moving

  39. Example #2: 12mL LNote: If you have a whole number, the decimal is always at the end of the very right number. Example 12.0 The Decimal is moving

  40. Quick Quiz- Conversions!

  41. Metric System Foldable!!
