6th grade: Lab #10 due TBD
6th grade, Lab #10,  Magnetism is due TBD  We are exploring the structure of the earth, and among other things, how the outer core is related to Earth's Magnetosphere.  The students will turn in three papers for this lab:
1.  Drawing (from the lab activity) and labeling of "Opposites Attract".
2.   Drawing (from the lab activity) and labeling of "Likes Repel".
3.  Well-written half page on some aspect of magnetism (Earth's magnetosphere, Michael Faraday, Laws of Magnetism, Electromagnetic Induction, Magnetic domains, Magnetite/Lodestone, in animal brains for navigation and migration...Pigeons & Dolphins, etc.)

1st State Standards Assessment on Wednesday, 12/17
The first State Standards Assessment will be on Wednesday, 12/17These assessments are based on the California State 8th grade Standards in Science and will only be eight questions. 
I review the guidelines for the assessment the day before.  If the student studies the guidelines the night before, there is no reason why he/she will not pass the assessment ("Master the Standard").  I teach DIRECTLY to the Standard with deliberate and directed set of guidelines. 
There will be eight "Standards Assessments" through the year. 
The student must get a minimum of six questions correct (out of eight) to "pass" the Standard.  The student will be given two chances to pass the Standard with different forms of the same test.  Additionally, the student must pass six of the eight Standards through the year to pass the class.

To review:
The student will be given "Guidelines" for each Standard in preparation for "Mastery"
To pass a given standard, the student must get six of eight questions correct
The student has two chances to pass each Standard
Eight Standards will be given through the year; the student must pass six of them

Lab #8, "Expansion & Contraction of Solids & Gases" due Tuesday, 12/09
Lab #8, "Expansion and Contraction of Solids and Gases",  will be due on Tuesday, 12/09
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, Tuesday, 12/16   read more ...

Lab #8 (6th), #7 (8th) is due on Friday,11/21

Lab #7 (#8-6th), "Sublimation and Dry Ice" is due on Friday, 11/21. 

If you were absent, you may download the form, under "Class Files" (or click), Edit Lab: Investigation into Sublimation and Dry Ice , buy some Dry Ice at a local store and do the lab at home. I get "Dry Ice" at Albertsons in Thousand Oaks.  I don't know if the local Albertsons carries it or not.  I've been told that Ralphs and Smart and Final carries it.

No "Extra Research" is needed

Last day for a late grade:  Friday, 12/05

Download & Print "Test Guidelines: Physical Changes"

Test Guidelines - Physical Changes

We are beginning a new unit, "Physical Changes".  Make sure you download and print the guidelines for the test at the beginning of the unit, so you could check it off and study as we go.

The Guidelines Physical Changes are located in "Class Files" (to the middle right of this page).  The file is called  Edit Test Guidelines "Physical Changes" (or click this link).  A more interactive guide for download was made by a student, Edit Test Guidelines: "Physical Changes" a Student's Version (or click this link) is located above the normal "Test Guidelines".  This is one of the four major tests of the year!!!

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.

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!
