Science Joke of the Day (Yes there actually are science jokes!)

Two molecules are walking down the street and they run in to each other.
One says to the other, "Are you all right?" "No, I lost an electron!" "Are you sure?" "I'm positive!

Science 9:  We are continuing with our unit on electricity. Here is a list of topics we have covered so far:

i) What is electricity ?
ii) Charge, Current, and voltage.
iii) I = Q/t   V = E/Q    E = VIt
iv) Circuits
                   i) Parallel
                   ii) Series
v) Resistance in circuits
vi) Kirchoffs Laws
vii) Ohms Law   R = V/I
viii) Circuit puzzles

upcoming topics

i) Power
ii) Energy efficiency in our own homes
iii) Why is my power bill so high ?

Remember that JOURNALS ARE DUE THIS WEEK !

Science 10: Our Chemistry unit is beginning to wind down. Here is your list of                                             " Things I should know "

i) Atomic structure
ii) Writing and reading formulas for compounds
iii) Balancing chemical equations
iv) Types of reactions
v) Moles with elements and compounds
vi) Acids and Bases

upcoming topics

Carbon compounds

Physics 20:  This week we will be looking at diverging mirrors and finishing our " Reflection of Light"
                    unit

This means and exam is on the horizon. Be sure you know how to locate and describe images in mirrors.

After this we will be examining the refraction of light.


Biology 20: Our invertebrate study is over. Make sure your last dissection assignmnets are in. This week
                    we will be working on a summarizing project to help you organize the information on this
                    rather large unit.

Biology 30: This week we wil begin by looking at the function of the kidney and how Nephrons clean
                    the blood. The following system studied will be the endocrine system

Chemistry 30:  The unit on equillibrium is winding down. Can you...

i) Define static and dynamic equillibrium
ii) Apply the collision model to equillibrium
iii) Determine a rate law and use it
iv) Derive and use an Equillibrium expression.

Celebrate St. Patrick's Day With Homework Club!

Homework Club is on today in the library after school. Grab your books and bring all of your problems/questions (science, not personal, please) and we will work through them together.

Hello, everyone.

One thing you may have noticed is a couple of links showing up at the side of the blog. One is for Chem 30 and the other for Sci 9. These are some great resources for you to use. They will provide you with notes and practice on the topics we are studying . If you miss a class or might want to do some review you will find them very valuable.

This next week:
Science 9:  Electricity is on the menu. We will be looking at parallel and series circuits as well as OHM's
                  Law. Be sure to keep that journal up to date as a lot of new terms have come your way.

Biology 20: Make sure your Arthropod presentations are ready to go next class. After this we'll have
                    two dissections. The Grasshopper and the Crayfish are waiting.  Last call for the Worm 
                    dissections !!!!!


Biology 30: Notes on the brain and the nervous system on the way. After this we will be having an
                    exam on the Skeletal/Muscular system and the Nervous system.


Physics 20:  Test on sound on Wednesday. Be sure to study. The next topic will be our unit on light.

Chem 30: The sheets on free energy are due next class. Our Energy in reactions unit is now complete
                 so you know an exam is around the corner


Stay tuned for more useful links that you can access. As I find them I'll post them at the side. They are in Blue lettering.

Website Information For You

Hi Girls, here's Mr. C getting a tutorial on embedding a link while giving you the info on the website you used in chemistry class today.  The link for the Chem 30 course is Chemistry 30.  Within this link, we covered 3.1 today.   Have a great weekend from Mr. and Mrs. C!

Science 9:   This week we are well under way with our electricity unit. Some key terms you'll need in your
                    journals are:

Charging by induction and contact
Charge
Electricity
I=Q/t

Don't forget 9-3  you have an exam coming up

Biology  20:  This week is get that worm dissection lab finished week. They are due by friday and be sure
                      to read carefully so your diagramming is complete

Biology 30:  We've finished our notes on the Skeletal and muscular sysytems. We will be looking at the
                     circulatory system next. Make sure you keep current with the vocabulary.

Physics 20:  The next chapter will be on interference with sound waves. Bring your calculators to class
                     you will need them.

Science 10:  We have covered the basic structure of the atom and are looking at chemical bonds and
                    molecules. Don't fall behind as this week we will be working on skills like naming compounds
                    and writing formulas.


Make sure if you miss a lesson to bring any missed notes to me to be photo copied. If you are having troubles homework club will be starting next week. It is looking like Thursday after school will be the day.
