New Units: 8th "Physical Changes"; 6th Seismology
8th Grade:  We are starting a new unit on Physical Changes in  November.   The only homework at the beginning of the unit is to study their notes and make "flashcards".  This week, we are looking at "States of Matter", "Kinetic-Molecular Theory", Molecules and Atoms, then leading into "Changes of State".  We will have a lab in a couple of weeks on "Dry Ice and Sublimation" (lab #7).  Thank You

6th Grade:  We will be starting on "Seismology" in mid-October.  We will be learning about earthquakes, the structure of the Earth, forces within the Earth, and the causes of earthquakes and crustal plate movement.  This is going to lead us into a couple of labs dealing with the importance of building design in the survival of an earthquake.  The students will be building toothpick "models" and have a competition as to which design is the strongest.

This is a very easy lab which consists of two worksheets that focuses on the Scientific Method.  These will be completed in class on Wednesday and Thursday.  The students will work with their lab partner on both worksheets.  Both worksheets will be due together on Friday.
This lab will not follow the usual lab form.

Last day for a late grade: 9-27

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 

There are also many good study apps the students can download on their phones.                                                                                                             

The students should be able to make a minimum of 3-5 flashcards per night. This, of course, depends on how much new material is introduced.


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

The students have a worksheet they completed in class.  There are four sections:

1.  Pure water w/ hypothesis and observations

2.  Pure Alcohol w/ hypothesis and observations

3.  50% Alcohol, 50% Water w/ hypothesis and observations  

4.  When the rag was on fire, but did not burn, how do you know the solution was   50% water and 50% denatured alcohol (use your observations to support your answer)?

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

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!
