For Homework, answer the following questions in your science notebook ( for all classes but Periods 2 and 4):
1. What is volume?
2. What units do we usually use to measure volume in science class?
3. What do we call the curved line that we use to measure liquid in a graduated cylinder? M _ _ _ _ _ _ _.
4. What device do we use to measure liquids? (Hint: yes, it really is that easy ; )
5. What is 1,000 mL equal to?
6. Read these graduated cylinders:

Topic: Measuring Volume
Obj: TSW:
- use two methods, measurement and calculation, and water displacement to determine the volume of various objects.
- Do the BIG INCH
- A number is a quantity, a multiplier for a unit.
- A unit is an amount, always the same size, that countries and groups have agreed to use.
- Customary units include: inch, foot, yard, mile; cups, pint, quart, gallonLength: 12 inches = 1 foot; 3 feet = 1 yard; 5,280 ft = 1 mile1 quart = 2 pints; 1 pint =2 cups; 1 cup = 8 ounces;1 gallon = 4 quarts = 8 pints = 16 cups = 128 ounces;Problem with customary system: conversions between different units are based on different numbers.Ex: 1 ft. =12 in. 1 yd. = 3 ft. = 36 in. 1 mile = 5,280 ft.
1. The basic measurement unit of length in the Customary System is the Inch.
a. Measurement - Every measurement has two parts: number (quantity) and unit.
b. (length=distance between 2 points).
c. There are 2 main systems of units: Customary and Metric (S.I.)
- Metric Units of length: cm, m, km.
m = Meter, basic metric unit of length.
Magic number: 10. Conversions from one unit to another are all multiples of 10. Ex:
- 1 km = 1,000 m
- 1 meter (m) = 100 centimeter (cm);
- 1 cm = 10 millimeter
IN THE METRIC SYSTEM, WE USE DECIMALS FOR PARTIAL UNITS, NOT FRACTIONS.
Tomorrow: Volume
Vocab: (write vocab words in notes, words + definitions in vocab section)r
quantitative- data with numbers. Ex: length, volume,etc.
qualitative - observations or data without numbers. Ex: color, texture, hardness.
