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.

Monday, January 23, 2017

Homework tonight: 

Insert Act. 9 ("Measuring Mass, Calculating Density") packet in your science notebook.   Staple or tape it in. Copy the vocab words + definitions  into your vocab section, word for word.  Selected students in Period 4 assigned to complete remedial "Volume Practice", please complete that work and hand it in tomorrow.

Science Mid-Terms 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.

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.

1/13/17 - Homework for the long weekend: 

Midterm Assessment Review packet - All students should answer Questions 1-9 on page 1. If you find that you can not answer 1 or more questions on the first page, then answer an equal number of questions on later pages, so you answer at least a total of 9.  

Extra credit: answer all 25 questions by Tuesday's class.

Thursday, January 12, 2017

no homework except to complete the volume review from yesterday if you did not turn it in today.

Wednesday, January 11, 2017

All periods but 6: 

Learning Check : Volume
Answer all questions

Name ________________                        Date _____________   Per. ____________

Learning Check: volume
   1.       What is volume?

   2.       Name 3 units we can use to measure volume:


   3.       What are two ways to measure the volume of an object?

a.       ___________________________   _________________________ and

b.      _________________________ and _________________________.

   4.       If you have an irregularly shaped object (like a rock), which of these  methods  should you use to measure volume of the rock?

   5.       1,000 mL = 1 ___

   6.       1 ml = ___ cm3    (answer how many in the blank)

  7.       What is the formula for calculating the volume of a bar or cube?
V = ___ x ___  x ___

   8.       What is the formula for calculating the volume of a cylinder?
V = ___ x ___  x ___


L = 7 cm
 
Now, solve these volume problems:







 
    9.       H = 9 cm
         L =  7 cm
         W = 2 cm 
     
             
Volume  = Length x Width x Height or  
               =  ___cm  x  ___cm  x___cm
               =  ___cm3 
    
 
L = 9 cm
 
                                                
   10.  


 



L = 9 cm
H = 3 cm
W = 8 cm

  Volume  = ________x Width x Height or 
               =  ___cm  x  ___cm  x___cm
               =  ___cm3 


  11.  
    L = 10 cm
    H = 7 cm
    W = 8 cm


 





Volume  = ________x ________x ________
= ____ ____

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
  • 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.
    • 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.
    b. (length=distance between 2 points) 
    c. There are 2 main systems of units: Customary and Metric (S.I.)  
    • Customary units include: inch, foot, yard, mile; cups, pint, quart, gallon
      Length: 12 inches = 1 foot; 3 feet = 1 yard; 5,280 ft = 1 mile
      1 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.
    • 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.
