Water Unit Study Guide, pt. 2


15. Corrected version: H = 4 cm, L = 6cm, w = 2 cm
   A (top)= L      x     W
   A        = 6 cm x  2 cm= 12 cm2
    V =   L      x     W    x   H
    V = 6 cm x  2 cm    x   4cm = 48 cm3
D = m/v  (where mas sis given as 24 g)
   =  24g/48 cm3 = ____ g/cm3          

16. water            

                                 oF          oC

           melts at:   32            0
           boils at:    212         100

17. Elements vs. Compounds: 

Element:
  •        consists of only one kind of atom,
  •        cannot be broken down into a simpler type of matter, and
  •        can exist as either atoms (e.g. argon) or molecules (e.g., nitrogen).
 Compound:
  •        consists of atoms of two or more different elements bonded (bound) together,
  •        can be broken down into a simpler type of matter (elements) by chemical means (but not by physical means),
  •        has properties that are different from its component elements, and
  •         always contains the same ratio of its component atoms.
Both: made up of atoms

No homework tonight!  But if you owe me something, this would be a good night to work on it.

Monday, March 24, 2014

Homework tonight:
For homework tonight: from the blog, copy vocab words to notes, copy words + definitions to vocab section. Be sure to the note at the bottom of this post!
Variable - Any factor that can change the outcome of an experiment.
Controlled variable - A variable in an investigation or experiment that is held constant.
Dependent variable - The observed phenomenon that is being measured; the result that you measure at the end.
Dissolve - To break down into smaller particles using a solvent. A solute (like sugar) dissolves into a solvent (like water) to form a solution.
Independent variable - the variable that an experimenter chooses to change or manipulate, or play with.
Physical change - (you should already have this definition) Change that does not alter the composition of a material. Ex: change of state; breaking up a piece of material into smaller pieces.
Saturated, saturation - When the maximum amount of a substance (a solute) has dissolved in a solvent.
Soluble, insoluble - A substance that is able to dissolve in a solvent (liquid or gas).
Solubility - how well a substance can dissolve in a certain solvent such as water; solubility can be measured and varies from substance to substance.
Solute/solvent - the solute is a substance that dissolves in the solvent. Ex: sugar in water
Solution- The mixture that results when one substance, the solute, dissolves in the solvent, another substance - usually a liquid such as water.

If you already copied all of these vocab words, then please prepare a word wall vocab card using one of these words and their definitions.   Word wall cards must be on a regular size (81/2 x 11 inch) piece of paper or half a sheet.  Make it colorful and creative, make the defined word large and its definition small.

3/17/14- Happy Saint Patrick's Day!!!
All classes:  make sure you get your Revised Permission Slips signed for our Soundwaters field trip to the Cove on Thursday. 

Periods 2 and 5: Write a Reflection on what you learned in class today about science.Make sure you write 5 good sentences.

Periods 6 and 1, copy the following vocabulary into your science notebooks: 
The vocab words go in your notes, the words + definitions go in your vocab section!
gas - substance that has no definite shape or volume; gas particles spread far apart.
liquid - substance with definite volume but no definite shape; particles in a liquid spread far apart enough to flow or pour and take.
particles - characteristic smaller pieces or parts, such as atoms or molecules, that all substances are made of. Ex: Water is a compound made of identical water molecules; element gold is made of identical gold atoms.
phase - a homogeneous state of matter - gas, liquid, or solid. During phase change, the particles do not change, the only change is arrangement & distance between particles.
physical change - difference in appearance that does not change the make up of the particles. Ex: break or tear material into smaller pieces; during a phase change from solid to liquid (melting), liquid to gas (boiling, evaporating), solid to gas (sublimation), gas to liquid (condensing), or liquid to solid (freezing).
physical properties - A characteristic of a substance or material, such as color, density, flexibility, hardness. These properties help identify pure substances and don't change if the sample is large or very small. They are intrinsic properties.
quantitative data - measurements, such as volume or mass
qualitative - characteristics people can perceive without making measurements.

Homework tonight: read "The Periodic Table Expands Once Again" and answer the 4 Common Core questions.  Be sure to R.A.C.E. the answers!  
R = Restate the question;
A = Answer the question;
C = Cite evidence; and
E = Explain how the evidence that you cited supports your answer.
For this activity, check your work against the R.A.C.E. rubric to get your best possible result. No Fail areas are:
1) Restate the question - Remove the 'W' word and Question mark, move the verb (ex: are) so the statement makes sense; and then
       2)  Cite Evidence - signal that you're bringing in information from the text by starting your sentence with something like: "The text says...", "It says in paragraph __ that...", "Evidence includes....", "I know this because ......" "The author states.....", or "I read that......".

Happy Last Day of Vacation!
No not really.  Teachers go back to school on Monday, but students get another day off.  
 
So, since our Unit test and our Element Project due dates were both snowed out, here's the plan: 
Monday - no school for students....only for teachers. 
Tuesday - Element Projects due; Review for test
Wednesday - Unit Test and start work on our next unit (Water)
Bottom Line:  Study for your test!  Also, Get those element projects done!  Tips for those of you who did not yet turn in an element project:
a) use the assignment package as a checklist ;
b) If you're having trouble finding information about environmental effects of your element, do a Google search with your search term in quote marks to make your search more accurate.  Ex: "environmental effects of iron".  Use the same technique for health effects or applications (uses).
c) find a diagram or photo of an atom of your element and include it in your project.  Use Google or another search engine, type in "diagram or photo of a _______ atom" and type the name of your element in the blank. Then click on image search and you should find an image you can use, like either of these:
d) Re-read your own writing, to make sure you said something that makes sense - I've seen lots of phantom words and phrases so far.
e) Citations: Include the name (web address)  of at least one of your sources of information. 

Consider emailing me your project before Monday night if its not on a poster board to get it out of the way and get it graded sooner.

Enjoy the rest of vacation!

  1. Your friend says you should buy a certain game system that uses uranium batteries.  They are cheaper and last longer but they are radioactive and are not as safe as systems that use regular batteries.  Also, when they are used up, you have to dispose of them in special dumps or they will poison the water. What model should you buy?  Discuss the tradeoffs.
Make a choice. Use the word "trade-off". Discuss advantages and disadvantages (as many as you can find) of the choice you made. Ex: 
"I would not choose the system with uranium batteries. Disadvantages include that uranium batteries are radioactive, and they must be taken to special dumps for disposal. These disadvantages outweigh the advantages that uranium batteries are less expensive, and last longer, than other batteries.  This is why I would not choose a system with radioactive batteries. 
  1. When you dilute a substance, what are you doing to it?
Adding water

  1. If you dilute a solution enough that you can no longer see the color:
    1. Has all the solute been removed?                                                           __No_
b.    How can you tell if solute is still in the solution? 
Use an indicator such as ammonia_
    1. What did we do in our lab that showed that a solution contained copper even when we could no longer see the color in the diluted solution?
Added ammonia to indicate if there was any copper in solution that was at too low a concentration for us to see with our eyes.

    1. What can you conclude about the chemical that we added?
_ Adding ammonia indicates if there was any copper in solution that was at too low a concentration for us to see with our eyes

    1. What Law tells you that the solute was not simply destroyed?
Law of Conservation of Matter

  1. What does dilution do to the concentration of a solute or toxin in liquid waste?
Adding water reduces the concentration

  1. What is serial dilution? 
Adding water over and over (in a series of steps) to reduce the concentration of a toxic chemical to within legal or environmental limits
