Hello to all,
I wanted to get this posted now, although there may be a few minor changes after I meet with my counterparts from Central this afternoon. I will add any changes in a new color or bold type or something of the sort. Anway, depending on the weather and the number of snow days, I plan to give the test over Mixtures and Solutions next Wednesday, December 17, 2008. Here is a list of points to study:
VOCABULARY
Students should know the meanings of the following vocabulary words:
- mixture
- solution
- solvent
- diatomaceous earth
- NaCl
- evaporate
- crystals
- properties
- compound
- solubility
- concentration
- precipitate
- solute
CONCEPTS
Students need to know:
- the three ways we separated mixtures in class
- what happens to a liquid when it evaporates
- how to determine if a given chemical forms a solution
- how to tell if a solution is saturated
- some ways salt is used today
- the two ways salt is obtained
- how to determine the total weight of a solution given
Also, there is an online test that students can take on my web site. I hope that helps everyone get a head start on studying. The test is worth about 51 points at this time. If we change anything that may add or subtract points, but I will update that as well! Also, students should be making sure there notebooks are up to date. The table of contents is right here.
Thanks
Mr. Yerington
