The document provides notes on various lab measurement techniques including: - Volume measurement using graduated cylinders and the displacement method - Mass measurement using a triple beam balance in grams - Temperature measurement using a thermometer in Celsius, Fahrenheit, or Kelvin It also discusses metric unit conversions using the "King Henry" method where the number of metric "hops" determines where to place the decimal, and the factor label method using unit cancellation.

1. Lab Measurements Notes from 9/25 & 9/30

2. VOLUME The amount of space an object takes up Instrument Used: Liquid- Graduated Cylinder (read at meniscus) Definite Shape Object- Ruler Infinite Shape Object- Graduated Cylinder – Displacement Method

3. Displacement Method 1. Read initial volume (1) of the water (without the object). Record: ____mL 2. Drop object into graduated cylinder. 3. Read the final volume (2) of the water. Record: ____mL 4. Find the volume of the object by using the formula: Volume of Object = vol. 2 (mL) – vol. 1 (mL)

4. Volume of a Regular Shaped Object Formula: L x W x H Unit: cm 3 Volume-Irregular Shaped Object Irregular-Shaped Obj.- does not have 4 sides and/or straight lines. Method: Displacement Method Tool: Graduated Cylinder Unit: mL

5. Mass Unit: Grams (g) How much matter (stuff) is in an object Tool: Triple beam balance

6. Thermometer (p. 137-138) Measures temperature (average kinetic energy of all the molecules in an object. Uses the expansion & contraption of materials. Measures in Celsius, Fahrenheit, or Kelvin degrees.

7. Metric Conversions Notes from 10/13 – 10/15

8. The Metric System The metric system is a form of measurement. It uses units like centimeters and meters as opposed to units like inches and feet. There are two different ways to go about converting measurements in the metric system.

9. The “King Henry Method” When converting metric measurements, it may be helpful at first to use the “King Henry Method” Phrase: “King Henry Drinks Delicious Chocolate Milk” – (K-H-D-D-C-M) Diagram: K H D D C M I E E E E I L C C C N L O T K I T L O A I I g L m

10. The “King Henry Method” (continued) How ever many “hops” you have to make from the starting unit to the ending unit, that is how many places the decimal point will have to move. Example: K H D D C M I E E E E I L C C C N L O T K I T L O A I I g L m So, if your starting number was 1000 milligrams, you would move the decimal point 2 places to the left (because “King Henry” bounced twice to the left), and your number would be converted into 10 decigrams. Reminder, the units in the yellow box in the center are the standard units of measurement in the metric system: grams, liters, and meters.

11. Factor Label Method Once you understand the metric conversion process a little better, you can use the factor label method. The factor label method is useful because when you don’t have enough space or time to make a big chart, you can use simple multiplication.

12. F.L.M. Directions Let’s say you’re asked how many hours are in a week. You would go like this: 7 days 24 hours 168 hrs. 1 week 1 day You would cross out the units diagonally as you go along. NOTE: This example does not use the metric unit of measurement, but it can really work for any type of conversion.
