Mixtures and Solutions Test Next Week

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

Online Test for Cells, Brain & Eye unit available NOW!!

By popular demand I have posted an online sample test for the cells, brain and eye unit.  Keep in mind we are still working on this unit, so I would expect the students to know ALL the answers.  The actual in class test will take place sometime next week.  I have to see how far we get each day before setting a firm date.  It looks like it would be either Thursday for Friday of next week, though.  

You may click here to take the sample test.

Thanks
