    Lab #9, "Expansion and Contraction of Solids and Gases",  will be due on Tuesday, 12-08
    NO "Extra Research" is required.
      However, if you want to look up a few more applications of Charles' Law, the coefficient of linear or cubical (volume) expansion in industry, buildings, engineering and design, etc., you can help your grade on the lab!
    Or, just a general extension of the unit: "frozen smoke" (a gel that is the lightest solid.... 99.8% air),
    or the "Bose-Einstein Condensate", sometimes referred to as the "fifth state of matter"!!
    Note: The 'conclusion" for this lab is merely the 2nd worksheet I passed out for the lab.  It says. "Expansion and contraction...." in the upper left-hand corner. 

    Last day to turn in this lab for a late grade will be Tuesday, 12-15

    6th & 8th Make Flashcards
    This is a YEARLONG assignment. 

    Students should make "Flashcards" from their notes.  This is a great educational strategy.  Using flashcards will keep the student up-to-date, reinforce difficult concepts, prepare them for tests, and, MOST IMPORTANTLY will give them a good educational foundation in Science!  Put a question on one side of a 3" x 5" index card and the   answer on the other side                                                                                                                  

    The students should be able to make a minimum of five flashcards per night. 


    The students will be checked periodically for flashcards.  They will get some extra credit for making them.

    8th grade Science


    "Science is a way of thinking much more than it is a body of   knowledge."

    Carl Sagan

    Food for thought:

    "Time travel used to be thought of as just science fiction, but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out."

    Stephen Hawking


    Cyber-Science Links

    Dear Parents and Students- 

    Please note the section called "Class Files".  The “Class Rules and Expectations” along with “How to Write A Science Lab” are updated copies that you (student) received at the beginning of the year.  You should find them in your Science notebook/"handout" section.  

    Also, students, if you need any extra copies of some of the lab forms (“Table” and “Graph” worksheet forms), you may print these out for your use. 

    Lastly, for your reference, whether you want to check up on Tornado or Hurricane Scales, to find out whether the North American tectonic plate really does stretch around and includes part of northern Japan, or keeping up-to-date in astronomy, technology, marine biology, or any of the other sciences check out some of the website links below.  Go to Mars, zoom in on Olympus Mons, get updates about the rovers, Spirit and Opportunity,……… or, maybe you want to take a virtual submarine tour of the Gulf Reefs!
