February E.C. - Solutions, Colloids, and Suspensions DUE 2/21/17

Long Weekend Extra Credit: Solutions, Colloids and Suspensions

Due Feb 21, 2017

**You may choose to complete Part 1 only, or you may complete both Part 1 and Part 2.** 

THIS IS DUE TUESDAY, FEBRUARY 21, 2017

I will accept digital submissions if you like (in fact, I prefer it).  Please put all the information into one single document (e.g. a PowerPoint, a Google doc of some sort or any other common digital format) and email it to me at anne.lasovage@southfieldk12.org    **Write your name in the subject line so I know who is sending it!!!


Part 1


FIRST:

Research the following terms:  solution, colloid, suspension.

In your research, you must watch at least two videos. Write down which videos you watched.  You may also use other resources (online chemistry text, etc.)

Record a definition/meaning and an example of each term.  *Additional information is also welcome.


NEXT:

With materials you already have at home, make a solution, a colloid, and suspension.  (Get parent permission if necessary.)  Record what you put in each.


Once done, take a selfie with each of the mixtures (or take one selfie that includes all three mixtures).

MAKE SURE: I can see the mixture (for example, you could use a clear glass as your container)

MAKE SURE: I know which picture is which vocab (you could label them)

MAKE SURE: You are in the picture and I can tell it’s you!


!!NOTE: If you do not have a phone or do not have phone privileges, you can still do this assignment.  Your alternative is to make the solutions, write a description of the solutions, sketch them, and have a parent signature on each



Part 2 (if you complete Part 1, you are eligible for this extension)

Some references will classify a colloid as a homogeneous mixture.  Some references will classify a colloid as a heterogeneous mixture.  Why the disagreement?

For part 2, describe the position and reasoning of the homogeneous proponents.  Then describe the position and reasoning of the heterogeneous proponents.  (Why do they classify this mixture type in the way they do?)   Do not just copy and paste – put the arguments in your own words!!!!  Finally, after consideration, take your own position – would you classify a colloid as heterogeneous or homogeneous, and why are you taking that position?

SOME VIDEO LINKS

These are not the only videos that would be appropriate, but here are some which might get you started.  They vary.  Remember you must watch at least two videos for Part 1; the videos  can be from this list or you may find your own (there are plenty of informational videos out there).  **If you find your own, email me the link.
