2 Thinking Scientifically: Measurement

3  Scientific measurements are based on the METRIC SYSTEM.  What are some units we use to measure in the United States?  Liquid?  Mass?  Length?  Temperature?  Time?

4 Match each unit above to the following terms:  Liquid  Mass  Length  Temperature  Time

5 Metric Units of Measurement Liquid: Liters Mass: Grams Length: Meters Temperature: Celsius (degrees) Time: Seconds Prefixes: Kilo (1000) Hecta (100) Deca (10) (Base) Deci (.1) Centi (.01) Milli (.001) (Remember - King Henry died by drinking chocolate milk!)

6 LENGTH Basic Unit: Meter

7 1 meter is about the length of a yardstick plus a crayon

8 About how tall are these people? 1 meter (1m) is about the height of a doorknob.

9 1 millimeter (1 mm) = thickness of a dime 1 centimeter (1cm) = width of your little finger or the diameter of an aspirin.

10 10 cm = 1 decimeter =.1 m (or 1 dm) The width of a person’s palm. 10 m = 1 decameter (or 1 dam) This is just a bit longer than a first down in football.

11 1 kilometer (or 1 km) is just a little farther than half a mile or about 10-12 city blocks in Savannah. Begin Odometer Check ½ Mile 1 Kilometer 1 Mile

12 Volume Basic Unit: Liter (Sometimes referred to as capacity)

13 1 liter = 1 L A liter is just slightly larger than a quart. 1 liter of water will weigh 1 kilogram

14 A medicine dropper will hold 1 milliliter = 1 mL (about 10 drops of water) 1 tsp will hold approximately 5 milliliters

15 MASS Basic Unit: Gram (Sometimes referred to as WEIGHT)

16 1 cm 3 holds 1 mL and will weigh 1 g if water is used. 1 gram (or 1 g) is about the mass of a paper clip or an aspirin tablet. A nickel = about 5 grams K H D B D C M

17

18 1 kilogram (1 kg) is also approximately the weight of your math book!!!! K H D B D C M Click here: How to use a triple beam balance!

19 TEMPERATURE Basic Unit: Celsius

20  Celsius:  0ºC and 100ºC are arbitrarily placed at the melting and boiling points of water and standard to the metric system  Fahrenheit:  Fahrenheit established 0ºF as the stabilized temperature when equal amounts of ice, water, and salt are mixed. He then defined 98.6ºF as the temperature 'when the thermometer is held in the mouth or under the armpit of a living man in good health'.

21  0 ° Celsius = 32 ° Farenheit  37 ° Celsius = 98.6 ° Farenheit  100 ° Celsius = 212 ° Farenheit

22 PRACTICE! Measure the following using the appropriate metric units. 1.The span of your hand (measure outstretched hand between tip of thumb and tip of little finger) 2.The length of your foot 3.The temperature of this room 4.The amount of liquid in your graduated cylinder 5.The amount of time it takes one person in your group to recite the alphabet (backwards!) 6.The mass of a microscope
