What units would you use to measure each of the above items? Materials: -PRIDE Card -IN -Pencil/Pen How do YOU measure things? What UNITS do you use to measure? 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! Metric System Length Mass Volume Meters (m) Grams (g) Liters (L) 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. These are the Suffixes…. Metric System Length Mass Volume Meters (m) Grams (g) Liters (L) Metric Prefixes • • • • • • • Kilo (k) – largest Hecto (h) Deca (da) BASIC UNIT!! Deci (d) Centi (c) Milli (m) – smallest Length Mass Volume Kilo + meter Kilo + gram kilo + liter hectometer hectogram Hectoliter Decameter Decagram Decaliter Decimeter Decigram Deciliter Centimeter Centigram centiliter Millimeter Milligram milliliter • They will never be by themselves, they have to be written with a suffix. Why do we have specific prefixes for each type of measurement… Length A big measurement Km A small one mm 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?_________ Quick Quiz What units (prefix + suffix) would you use to measure…. 1. 2. 3. Lesson 1: Length English vs. Metric Units Which is longer? A. 1 mile or 1 kilometer B. 1 yard or 1 meter 1 mile 1.6 kilometers C. 1 inch or 1 centimeter 1 inch = 2.54 centimeters 1 yard = 0.9444 meters Left Image: http://webapps.lsa.umich.edu/physics/demolab/controls/imagedemosm.aspx?picid=1167 Right Image: http://share.lancealan.com/N800%20ruler.jpg Metric Units 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? A. 1 meter or 105 centimeters C. 12 centimeters or 102 millimeters B. 4 kilometers or 4400 meters D. 1200 millimeters or 1 meter Measuring Length How many millimeters are in 1 centimeter? 1 centimeter = 10 millimeters 2.8 What is the length of the line in centimeters? _______cm 28 What is the length of the line in millimeters? _______mm • 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: 1. Length 2. Mass 3. Volume Good luck and happy measuring! Lesson 2: Mass English vs. Metric Units Which is larger? 1. 1 Pound or 100 Grams 1 pound = 453.6 grams 2. 1 Kilogram or 1 Pound 3. 1 Ounce or 1000 Milligrams 1 ounce of gold = 28,349.5 milligrams 100 kilogram = 220 pounds Metric Units 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? A. 1 kilogram or 1500 grams C. 12 milligrams or 12 kilograms B. 1200 milligrams or 1 gram D. 4 kilograms or 4500 grams Kilogram Prototype Image - http://en.wikipedia.org/wiki/Kilogram 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. 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? 70g 300g + _______ 373.35 g 3.35g = ________ _______ + ______ Lesson 3: Volume English vs. Metric Units Which is larger? 1 fl oz = 29.573 ml A. 1 liter or 1 gallon 1 12-oz can of soda would equal approximately 355 ml. B. 1 liter or 1 quart C. 1 milliliter or 1 fluid ounce 1 quart = 0.946 liters 1 gallon = 3.79 liters It would take approximately 3 ¾ 1-liter bottles to equal a gallon. Metric Units 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* 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. 43 What is the volume of water in the cylinder? _____mL 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 Liquid Volume What is the volume of water in each cylinder? 37mL 52mL 23mL Pay attention to the scales for each cylinder. Measuring Solid Volume 9 cm 8 cm We can measure the volume of regular object using the formula length x width x height. 10cm _____ 8cm 720cm3 9cm = _____ X _____ X _____ 10 cm We can measure the volume of irregular object using water displacement. 260cm3 Amount of H2O with object = ______ About of H2O without object = 200cm3 ______ 60cm3 Difference = Volume = ______ Lesson 5: Unit Conversions Great… How do I do conversions?
