Chapter 5 test practice (7th and 8th Grades)

8th grade test practice-The Nonliving Environment

Ch. 5 practice problems

Here is 1 link to study for the chapter 5 test.  You can access the Section 1 Self-Check quiz- Section 3 Self-Check quiz, Chapter review quiz, Standardized test practice, and there are also websites that can be visited (in the Web links section) that talks about Photosynthesis (and cellular respiration) .... and Extreme environments found on earth.

The test will have the same format as the Ch. 2-4 tests.  True/false questions, Multiple choice, vocabulary matching, and an essay question.

Lab deomonstration for interactions of human systems

The purpose of this lab demonstration is to show the cell membrane function.
The materials used in this lab are dialysis tubing, cornstarch solution, iodine solution, and a beaker.
The preparation for the lab is... cut a strip of dialysis tubing (about 4 inches long).  It needs to be soaked in water for approximately one minute.  One end of the tubing needs to be tied shut.  The cornstarch solution should be added into the tubing and then tied off, so that the tubing has a fleeting resemblance to a water balloon.
The procedure demonstrates how iodine reacts with starch.  The dialysis tubing/cornstarch solution should be placed into the beaker of iodine solution.  The minimum amount of time to wait for results is 5 minutes.
If the dialysis tubing is sealed on both ends, so that none of the cornstarch solution leaks into the iodine solution, the tube of white starch solution will change to a dark purple color.
During the procedure, iodine passes through the dialysis membrane and reacts with the cornstarch.  This is called diffusion.  The cornstarch is not able to diffuse through dialysis membrane because the size of the cornstarch molecules are relatively big. This demonstrates that the cell membrane is selectively permeable because Iodine molecules can pass through the dialysis membrane, when the starch molecules cannot.

Exploratory computers

I would like you to create a formal business letter during class today.  There are certain ways you should write letters.  Each way is dependent on to whom the letter is being addressed to.  Here are directions, that I would like you to follow, on how to write a business letter. 

Here is an example of a business letter that you can also use to help you through the letter writing process.
