questions 4-12 and
13,14,17,18

today in science we got some hand outs for the test on next thuresday

Today we did mental math and then Mr.Maksymchuk read us a story called its a book. We also worked on the practice assesment.

Scribe Post, Oct. 26/11

Today in science we talked about what we are gonna do to try get the stuff for being, mimes on strike. Then he did a homework check on what we did yesterday, then we corrected the assignment. After that we started watching a video about molecules. We then have to stay in for 2 mins at break (certain people wouldn't stop talking)REMEMBER YOUR $2 FOR MOGA IT IS DUE FOR FRIDAY!!!

Today in Math Mr. Maksymchuk gave us a sheet of math work we have been doing and we have to finish it.

Lead-Pb,82
plumbian is the abbreviation for Pb witch is the latin word for soft metals
it was thought to be one of the oldest metals in achamy.

today we corrected 2.7 questions 1-5 and then Mr.Maksymchuk talked.

is a chemical element with symbol Rf and atomic number 104, named in honor of New Zealand physicist Ernest Rutherford. It is a synthetic element (an element that can be created in a laboratory but is not found in nature) and radioactive; the most stable known isotope, 267Rf, has a half-life of approximately 1.3 hours.

tuesday oct,23 2011 day 1

today in math we did mental math now were getting a review for the test/assessment on friday, and corectting page forty 3.a 3.b 3.c 3.d and 3.e. ... home work for tonight is page 48 question 1,2,3,6

Americium (Am 95 are it's symbol on periodic table and it's atomic number) ( a radioactive metal found in nuclear reactors) is named after the country it was found in.

Iron is chemically labelled Fe on the periodic table of elements, from the root word of ferrum (a latin word for iron)

It's atomic number is 26.

Md

mendelvium is the 101 element in the periodic table. Its abrevation is Md. It was first identified by Albert Ghiorso, Bernard Harvey, Gregory Choppin, Stanley Thompson, and Glenn Seaborg in 1955 at the Lawrence Berkeley National Laboratory, California.

ES-Einsteinium
It was named after Aberta Einstein.

Curium is the 96th element of the periodic table, definition- a radioactive element not found in nature
but discovered in 1944 among the products of plutonium after bombardment by high-energy helium ions.

Nobelium is called (No) because In 1994, and subsequently in 1997, the IUPAC ratified the name nobelium (No) for the element on the basis that it had become entrenched in the literature over the course of 30 years and that Alfred Nobel should be commemorated in this fashion.

• Lawrencium is named in honour of Ernest O. Lawrence, the creator of cyclotron.

• it is called Lr because, the name lawrence, has the letters Lr in it.

• Lawrencium is a radioactive rare-earth metal. it is man-made

Sodium is the 11th element in the periodic table, the abbreviation for sodium is Na because the Latin word for sodium is natrium.

Antimony's checical symbol is Sb becasue it is made out of a lustrous grey metalloid, it is found in nature mainly as the sulfide mineral stibnite (Sb2S3) the symbol is Sb because sulfide mineral is Sb2

silver is called Ag because, Ag is an abbreviation of Argentum - the Latin word for silver.

Latin cuprum: from the isle of Cyprus, which is famed for its copper mines. Copper has been known since prehistoric time. It has been mined for more than 5000 years. The metal and its alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum.

`K` is the symbol for Potassium because, Neo-Latin Kalium. It's atomic number is 19.

10.24.11.Science Class

Maksymchuk Wants Periodic Table Assignment Done Today by 2:15 pm.
- Can Start Pre- Lab. ( 2.6 " Identifying Mystery Gasses " )
And If Your Done That . Text Book, ( Next to Sets Of Questions )

pg 59 1-5
read 58 and 59

this is what Mr. Maksymchuk wants for math.

Today for science class we are going to watch a 20 minute video with some questions.

* and remember your two dollars!

this is a cylinder
formula for total surface area of a closed cylinder is

A = L + T + B = 2πrh + 2(πr2) = 2πr(h+r)
here is the calculator

and here is the volume forumla for a cylinder.
V = πr2h

Below is a checklist for math and is ALL supposed to be done.


Checklist for Math:
1. Textbook 1.1
2. Textbook 1.2
3. Textbook "Mid-Unit Review" Pg. 21 Qu.1-11
4. Textbook 1.3
5. Photo Assignment.... (below)
Photo Assignment Checklist:
1. Title (Name of the Object)
2. Photo (*If web guaranteed, provide URL as credit)
3. Explicit- formula for surface area
4. Explicit- formula for volume
5. Calculator Link for surface area
6. Calculator Link
7. LABELS! (math 9, display name, savolume)

Today in science Mr. Maksymchuk talked to us about MOGA. He told us we have to pay $2.00 even if we dont want to. You can pay it over any period of time you choose. We wrote notes on gas testing, and watched youtube videos to follow.

Shapes Assignment

The object we chose is a rectangular prism.

The formula for surface area is- 2(d(h+w)+hw)                d- depth
                                                                                                                                     h-height
The formula for volume is- dhw                                                    w-width

http://www.csgnetwork.com/surfareacalc.html  -  is a calculator for surface area

http://www.csgnetwork.com/volumecalc.html   - is a calculator for volume

These calculators are for all types of 3d shapes

Hemi-Sphere

Volume of Hemisphere = (2/3)πr³
Total Surface Area(TSA) of Hemisphere = 3πr²
http://www.calculatorsoup.com/calculators/geometry-solids/hemisphere.php

This is a rectangular prism, the formula for calculating surface area is:

SA=2ab + 2bc + 2ac or SA=2(lw + lh + wh)

http://www.calculatorsoup.com/calculators/geometry-solids/rectangularprism.php and there is a link to the calculator that can be used for finding the surface area of a rectangular prism.

we got a a four-sided pyramid.

the surface area is A = 2bs + b2(the 2 is squared)

http://www.math.com/students/calculators/source/scientific.htm scientific calculator

cylinder

surface area formula: 2pir^2+2pirh

volume: v=pir^2h

http://www.calculatorfreeonline.com/calculators/geometry-solids/cylinder.php

this calculator link helps you find the surface area and volume of a cylinder.

Tetrahedron

This is a tetrahedron.

• formula for surface area: bh/2X4

• AbaseXht/1/3

• Calculator: http://www.livephysics.com/tools/math/area-and-volume-calculator.html

blah blah blah

cone

pic goes here

surface area formula is: S.A. cone = (pi x r x s)

Today in math class we did Mental Math #13. and we worked with partners on shapes!!!!

This is a homogenous because all the tiles are the same .

This is a heterogeneous mixture because there is more than one substance and there is more brown iin some squars than others .

this is a compound mixture because it has two or more stubstances mixed together

This is a solution because it is a mixture made up of liquids

This is a pure substance because this substance contains only one kind of particle

This is a picture of the floor in Mr. Maksymchuks room and this would be heterogeneous because the floor textures are all different.

this is a heterogenexpous mixture.

Recently we have been assigned to post pictures that are either homogeneous or/are heterogeneous. So, this is mine.

Above is a picture of a drum kit, the drum kit is heterogeneous because if you take the drum set apart it the pieces would all be different.

This mannequin is heterogeneous because the layers of the hair is uneven.

This paintbrush is heterogeneous because the paint bristles are uneven and the paint splatters are uneven also.

This is a water pump and a bunch of stuff under it this would also be heterogeneous because all of all of the items are different and have different pieces to them.

This is my drawing of a flower from art class, this is heterogeneous because the shading is all different.

This is a picture of a piano and this would be heterogeneous
