In Anatomy Class today we took the Chapter 2 test.  If you are home sick, in the Anatomy Journal, you should complete the Chapter 2 Study Helps work from your take home folders.  Then come to me when you get back to school and let me answer any questions you have before you attempt to take the test.  I can also drill you on some of the things that were on the test to help you get ready.  Please try to get makeup tests out of the way ASAP because the next chapter, The Cell has lots and lots of memorization.

 

Tomorrow we will take a new kind of root word test.  We put our Chapter 3 root words, definitions, example words and their definitions into the Academic Vocabulary part of our journal.  Tomorrow's quiz will have the usual, I give the root definition, you write the root and the example term, and in addition, you must give the definition for the example terms.  Download the Chapter 3 notes tonight from the Teacherweb site, and read the part of Chapter 3 that deals with the cell membrane and also the section that deals with how things get into and out of the cell. (We are skipping the cell organelles just now). 

 

 

 

In Chemistry class, we took a test on the chart on page 34 (everything except the section labeled Defined Standard), and also what I call the "how many's".  If you can't get those from someone in the class, please e-mail me and I will send you a copy.  That is a MAJOR test grade, so you really need to get caught up on that.  So far in Chapter 2, we have covered all of Section 1 and completed the Section 1 Review.  Yesterday we did a measurement activity, and learned about significant figures in measurement and also about percent error, and accuracy and precision.  That is covered on pages 44 - 46 in the book.  We also did some density calculations, and for homework last night completed p. 59, 16 - 19. 

 

Today we reviewed accuracy and precision and percent accuracy, and learned how to count the number of significant figures in measurements.  That is covered on pages 46 -48.   Look at Sample Problem Don p. 47.  Then we did Practice problems a and b on p. 48.  We will not use the complicated rounding rules on the bottom of that page, but rather standard ones that you have always used in math class.  After we learned to count significant figures, we then learned how to round off the results of calculations with measurements to a correct number of significant figures.  That was covered on pages49 and 50.  Try working the sample problems 1 -4 on page 50.  We had an assignment from a worksheet, but if you can do these they will substitute.Tomorrow we plan to work with using our calculators to do operations with scientific notation and developing conversion factors to change from one unit of measure to another.  That is covered on pages 51, 52, and on pages 41 and 41.  At the end of the lesson, you should be able to do all of the Secton Review on p. 42, as well as the practice problems on p. 42.  DO NOT use "King Henry" to convert measurements.  We must use conversion factors and dimensional analysis to solve chemistry problems.

 

Let me know if you are having problems.
