Hi students!
Congratulations on completing 1st Quarter.
Enjoy your Veteran's Day off, and give thanks to a veteran if you know one, or at least think about how much they have given to protect us.
7th Graders: Those of you who came in during lunches over the last weeks for the extra credit on the Anatomy lesson ("What's Going On Inside?") really helped your grades!
Homework due Monday: Fill out the first two columns for the K -W - L chart about the Cardiovascular system!
6th Graders: Homework due Monday: For our project, you will choose an article FROM THE PACKET and write an outline or draft editorial about it.
Hint:
1. Read the article,
2. Figure out what the Main Idea is (what events described in the article are most important?)
3. Choose a position either for or against those events.
4. Go through the article again and circle, highlight, or underline all supporting details (especially facts) that support your position.
5. Type out the Main Idea and Supporting Details to write your outline or draft editorial. An editorial is an article in which you give your opinion.
6. If you don't use a computer for your outline or draft editorial, try this. Write one idea or detail on a cut-out paper square (or sticky note, Post-It, or index card). Then put the ideas/details in the order based on which facts or details support which part of your opinion.
ALSO, you should already have shown me your completed Table of Household Hazardous Materials. If you have not, please work with a grown-up in your home and find at least 5 products, then fill out your table.

Vocab quiz tomorrow for all 6th and 7th graders. Homework assignment: study for quiz (and 7th graders also have to write answers on an SPP for some Analysis Questions on today's lab).
See the entry from 11/7/11 below for the list of words and definitions.
Extra credit available, for all 6th and 7th graders, since you looked at the blog. To get 1 extra credit point, on the front of your quiz, write down the word "hypothesis". For a second extra credit point, write down the definition: "testable prediction". As before, extra credit is available on the quiz if you write and study vocab word flash cards ("cards" can be any form of paper as long as a vocab word is written on one side, definition on the other, with your name written on 1 or more cards) if you bring them to the quiz.
The quarter closes tomorrow. DO well on the quiz and it could help your grade! Do poorly and it could help you.
* All 6th Graders: I need to see your completed Hazardous Materials Table tomorrow if you did not turn it in today.
* If you're one of those 6th graders who keep missing 2nd period [due to 1)advisory, 2) band practice], you need to contact a study buddy or someone else in one of my classes to find out what you'r e missing. Hazardous Materials Table and Editorial Project is due Nov. 15.

7th graders - Homework is to: 1) write 5 STAR note questions based on today's notes; and
2) Reflect on and revise your answer to the Challenge question ("How much carbon dioxide is in your exhaled breath? Give evidence").
Vocab quiz on the following vocabulary words on THURSDAY:
a) respiratory system - The system of organs that work together to take oxygen into the body and to remove carbon dioxide from the body. Your body uses oxygen to get energy from food, and carbon dioxide (a/k/a CO2) is a waste product from that process.
b) indicator - chemicals that change their appearance in different types of solutions. Ex: BTB
c) tendons - tissue that attaches muscles to bones
d) Ligaments - are pieces of white tissue that attaches the bones together at the joint.
e) bones - hardened connective tissue that forms the skeleton in most vertebrates.
f) growth plates - areas near the ends of long bones in children & teens that produce new bone tissue & determine the length & shape of adults' bones.
g) joints - A junction between 2 or more bones, usually allowing some motion.
h) Simple Machines - a machine that makes work easier by taking the effort put into the machine and changing its size, direction, or speed. Ex: lever, wedge, wheel & axle.
i) lever - a bar that is free to turn around a fixed point, called a fulcrum.
j) muscles - tissues in a system that help various parts of the body to move
k) contract - muscle cells slide over each other, making the muscle smaller, which pulls tendons and bones to cause joint movement. You bend your arm by contracting your bicep.
l) relax - muscle cells slide away from each other, making the muscle longer, which partly releases the pull on tendons bones; opposite of contract.k)
6th graders - For your project, complete the Household Hazardous Materials Table, which will be checked on Wednesday. Also, those of you who have checked the blog have an advantage. We will have a vocab quiz on the following vocabulary words on THURSDAY:
1) Atoms - tiny particles that make up each element. A pure sample of an element contains many atoms of the same type.
2) Element - is a substance that cannot be broken down into simpler substances by heating it or causing it to react with other chemicals
3) Molecules - two or more types of atoms held together by bonds
4) Compounds - substances formed when elements react. Substances made up of molecules (two or more types of atoms held together by bonds) are called compounds.
5). Hardness - what else will scratch it? What will it scratch?
6) Luster- is it shiny? In other words, does it strongly reflect light? If not, we say it looks "dull". If yes, it can be "brilliant" (very shiny); "glassy", "metallic", or "waxy".
7) Light Transmission - Does light pass through it? Transparent means light passes through it (ex: glass); Translucent means some light passes through it but it is blurry; and Opaque, which means that light does not pass through the material.
8) Texture - How does it feel when you touch the material? Is it smooth, rough, grainy, or gritty?
9) Flexibility - Does the material bend with gentle pressure? If no, it is inflexible; if it bends slightly, it is somewhat flexible; if it bends easily, then it is very flexible.
10) Reaction with HCl - does it bubble, smoke, change color, give off heat, light, precipitate, or gas?

ii) Non-metals - dull with no luster, not good at conducting heat or electricity, and brittle and not bendable.
2. Mixtures - What can equipment be used to separate mixtures into their parts? Name them.
3. When separating mixtures, you may need to separate: 1.liquid from liquid, 2. solid(s) from liquid,
3. small solids from large solids, 4. iron filings from sugar, and 5.dissolved solids (like salt or sugar) from liquid. If you had to separate the materials on the list that you just read, which of the following equipment would you use?
a. dropper -
b. screen -
c. filter paper in a funnel-
d. a pan with a heating source (burner, stove or sunny spot)
e. magnet.
4. Volume: How do you find the volume of an irregular object (ex: small candy pumpkin)? Explain.
5. Density = mass divided by volume. Complete the equation D = m/__. The density of water is __ gram per cubic centimeter or milliliter (for water, 1g = 1mL = 1cm3). If an object is more dense than 1g/cm3, it will (circle one): a. float b. sink c. hover d. disappear
6. How is a physical property different from a chemical property?
7. Know what you use each of the following measurement tools for:
a .meter stick (answer: _____________)
b. graduated cylinder (answer: __________)
c. triple beam balance (answer: __________)
d. spring scale (answer: weight)
8. Know the difference between physical change (change in size or shape without changing material) and chemical change (chemical change in material and its properties, ex: burning a paper, dissolve meat in acid).
Hey, stop feeding my fish so much - they're getting fat! :-)
