Homework on the Blog:
6th graders:  finish answering Analysis Questions on p. C-32-33, numbers 1-8.  If you can't find your copy, get it off of the Lab-Aids/SEPUP website linked at the right. Later homework this week will be copying vocab definitions into your pre-printed vocab sections.  The vocab words are printed at the bottom of this blog entry. 

7th Graders: we need to get statistical information for the Infectious Disease that you're studying:

Asthma (not really infectious, but allowed due to interest)
1980-99 CDC Asthma Surveillance Survey:
2003-05 Asthma United States http://www.cdc.gov/nchs/data/hestat/asthma03-05/asthma03-05.htm#asthma_prevalence

2005–2009 Asthma Prevalence: United States http://www.cdc.gov/nchs/data/nhsr/nhsr032.pdf

HIV / AIDS 
Various years, Diagnoses of HIV Infection and AIDS United States  http://www.cdc.gov/hiv/surveillance/resources/reports/2009report/
2006 - 2009 annual number of new HIV infections was stable overall from 2006 through 2009

6th Grade vocab to add copy definitions to vocab section:

1. Controlled variable - A variable in an investigation or experiment that is held constant.
2. Dependent variable - The observed phenomenon that is being measured; the result that you measure at the end.- substance that has no definite shape or volume; gas particles spread far apart.
3. Dissolve - To break down into smaller particles using a solvent. A solute (like sugar) dissolves into a solvent (like water) to form a solution.
4. gas - - substance that has no definite shape or volume; gas particles spread far apart.
5. Independent variable - the variable that an experimenter chooses to change or manipulate, or play with.
6. liquid - substance with definite volume but no definite shape; particles in a liquid spread
   far apart enough to flow or pour and take.
7. particles - the characteristic smaller pieces or parts, such as atoms or molecules, that all substances are made of. Ex: Water = compound made of identical water molecules; gold (an element) is made of identical gold atoms.
8. phase - a homogeneous state of matter - gas, liquid, or solid. During phase change, the particles do not change, but their arrangement & distance from each other do.
9. physical change - difference in appearance that doesn't change the make up of the particles Ex: tear or break 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).
10. 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.
11. physical properties - characteristic of a substance or material. Ex: color, density, flexibility, hardness. These properties help identify pure substances and don't change if the sample is large or very small.
12. quantitative data - measurements, such as volume or mass
13. qualitative - characteristics people can perceive without making measurements.
14. Saturated, saturation - When the maximum amount of a substance a solute has dissolved in a solvent.
15. solid - substance with definite shape and volume, as particles are closely packed together, and move very little (vibration).
16. Soluble, insoluble - A substance a solute that is able to dissolve in a solvent, (liquid or a gas).
17. Solubility - how well a substance can dissolve in a certain solvent such as water; solubility can be measured and varies from substance to substance.
18. Solute/solvent - the solute is a substance that dissolves in the solvent. Ex: sugar in water
19. Solution- The mixture that results when one substance, the solute, dissolves in the solvent, another substance - usually a liquid such as water.
20. substance - Anything that has mass and takes up space.
21. vapor - The gas phase of a substance (ex: water vapor, not steam, is gaseous water).
22. variable - Any factor that can change the outcome of an experiment.
