Homework for Periods 1, 2, 6, & 7: Density Worksheet
NOTE: the density problem on the back page lacks a mass term, so the mass of the irregular object is 7.5 grams.

Science MidTerms Tomorrow. Please do the following:
1. Finish answering the Science Mid Term Review Packet (Questions 11, 12 and 13).
We will discuss these briefly tomorrow if we did not go over this in your section today.
We will discuss these briefly tomorrow if we did not go over this in your section today.
2. Tonight, study the answers to your Science Mid Term Review Packet.
3. Bring your Science Mid Term Review Packet to your Math mid term, so you have something to study after you finish the math mid term.
4. Bring a number 2 pencil with you to the test, and you may bring your own calculator to use, but a phone or tablet can not be used as a calculator.

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.
