Homework for November 2, 2011: Study Guides for 7th graders and 6th graders. Sixth graders will find their study guide lower on this page, after the 7th graders' guide.
As discussed last week, my 6th and 7th graders will have a short Assessment tomorrow. Check to be sure that you have the correct grade before doing your work on one of the following study guides:
7th Grade: Print this out & write answers to all questions. Check 1-2-3 (that means your minds and notebooks, your study buddies, and the internet). Turn it in on Thurs., Nov. 3.
1. Digestive system:
a. Be able to name and describe the function of the parts of the digestive system on a diagram. See http://www.ashwini.org/asknk/index.php?option=com_content&view=article&id=81&Itemid=74
b. Know where mechanical digestion takes place, where chemical digestion takes place, and where both take place (hint: Spit).
c. What if you lost your liver? http://kidshealth.org/kid/htbw/liver.html. Better find it and take care of it!
2. Respiratory system: know where it is and what it looks like. See http://www.lungusa.org/your-lungs/how-lungs-work/?gclid=CNar48unmKwCFcp65QodUQUUOg

3. Know how to Study People Scientifically:
a. What is a hypothesis and what words should it contain? ___ and _____.
b. You are designing (or planning) an experiment. Name the parts of an experiment:
1. Problem 2. H__________ 3. P__________ ; Materials 5. D_____ 6. C_________
c. What is a variable?
d. How many variables should you allow to change in an experiment?
e. What are controlled variables?
f. Data: know the difference between quantitative and qualitative data.
4. Medicine Clinical Trials:
a. Define: advantage
b. Define: disadvantage
c. Define: Trade-off.
d. what is a placebo?
e. What is the placebo effect?
f. How is a placebo different from the Placebo effect?
g. In a clinical trial, do you want a large sample size or a small one? Which is better and why?
5. Review the reading packet (pp. B28-37) from the Support Systems (chicken wing) lesson.
a. What is bone?
b. What is bone's function (what does it do)?
c. What is muscle? What is muscle's function (what does it do)?
d. What are the 3 types of muscle?
e. What are tendons?
f. What are ligaments?
6th Grade: study Guide - If you got less than 70 on your last test, you also have to get a parent signature and write a reflection.
6th Grade: Print this out & write answers to all questions. Check 1-2-3 (that means 1: your minds and notebooks, 2: your study buddies, and the 3:internet). For any new material, you have the information you need in this sheet and we'll discuss tomorrow. Turn in your Study Guide on Thurs., Nov. 3.
1. Elements -
a. What is an element?
b. Look at the Periodic Table in your agenda. Each element has a symbol with a capital letter, and sometimes also with a lower case letter. Ex: C is the element Carbon, O is the element Oxygen and Ne is the element Neon. Two capital letters together means you have a compound made up of two or more elements. Ex: CO is the compound Carbon Monoxide. Is H an element or a compound? _________ Is He an element or a compound?_________. Is NaOH _________an element or a compound?
c. Look at the Periodic Table in your agenda. Elements can be broken down into groups, including:
i) Metals - they have a shiny luster, good at conducting heat and electricity, and are bendable; Look up and give some examples -better to use chemical symbols. Ex: _______,_________,__________); and
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! :-)
