upcoming test & starting a new chapter

The test on chapter 17 will be Thursday -- it will be ONLY on chapter 17.  You have been reviewing, so go over the material once again, from the textbook, in your journals, worksheets and labs, and on the blog posts, and from quizlet.

But wait, there's more:
- Start a new section in your science journal for the NEW CHAPTER: leave a page to summarize everything we do, like the one I did for chapter 17 Classification of Matter, above.
- Read Chapter 18, section 1: The Structure of the Atom  In your science journal, write out the vocabulary (with meanings); copy figure 1 on p. 545 along with the word-blurb, and answer the questions 1-6 on p.549.

-start to memorize the chemical symbols of the elements, starting with the common ones listed on page 544. Make flash cards.

A little bit more on the Cloud Chamber, which is like the bubble chamber mentioned in your text - that piece of scientific apparatus that can detect the smallest sub-atomic particles of matter.  Does anyone want to build one?  Extra credit!  I'll get the dry ice!
