Week of Sept. 30th - Oct. 4th

Monday 9-30-13

Objective: demonstrate an understanding of the properties of water.

Agenda: 1. Pre-Lab ( objective, background information)2. Lab ( I will grade journals as you work at each station) Write up lab report on page 23R-24L. Paste/Tape web quest on page 24R3. Closure/Clean upHomework : cut out carbohydrate figures ( due tomorrow)

Properties of Water Lab: What Makes Water Special?

Objective: demonstrate an understanding of the properties of water.

Background: Water has some peculiar properties, but because it is the most common liquid on Earth, we typically do not recognize how truly peculiar water really is. Water is everywhere. It's in the air we breathe. It's in our sink faucets, and it's in every cell of our body. Water is an unusual substance with special properties. Just think about the wonder of water:

How does water rise from the roots of a redwood tree to the very top?How do insects walk on water?Why does ice float rather than sink?Why do people become seriously ill, or die, if they go without liquid for a week or so?How would life in a lake be affected if ice sank and lakes froze from the bottom up?

When it is your turn to run your station: read aloud the information and instructions to your group.Perform any necessary activity & clean-up…get help from lab table-mates when you need it. Then, lead the discussion of what happened. Run one test at a time with everyone in your group paying attention.

What to write down: the number of the station, the title of the station, the data from the station (i.e. what you observe (qualitative data), any quantitative data, & answer any question(s) for that section.

Clean-up – it is imperative that you clean up each station so that the next class will be ready to go!

Tuesday, Oct. 1st Objective: demonstrate an understanding of the properties of water; Compare the structures and functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids.

Agenda: 1. Carbohydrate Notes ( checking today in class) – 25L2. Finish Properties of Water Lab ( you need TWO stations plus your web-quest finished3. Clean Up

Homework: Study notes for carbohydrate lab tomorrow and you never know when a QUIZ may POP….Also, finish properties of water web-quest.

If you DO not have a safety contract on file you will NOT participate in lab.

New Grading Scale: 50 ( daily), 10 ( homework), 40( tests/projects)

Carbohydrates (polymers) a. provide energy for living cells b. . contains carbon, hydrogen and oxygen in a 1: 2:1 ratio c. Monosaccharides - single sugars that serve as a major fuel for cells and as raw material for building molecules.

glucose (C6H12O6) most common=sugarfructose=fruitsgalactose=milk

D. disaccharides- linking two monosaccharide's togetherE. polysaccharide - many sugars formed by joining monosaccharide

-Excess sugars can be stored as starch1. Glycogen can release glucose from the liver when glucose levels become low.2. Starch (spaghetti)3. Plants store excess sugars as plant starch in the chloroplast.4. Cellulose gives plants their strength and flexibility (wood and paper)5. Chitin is another structural polysaccharide, is

found in the exoskeleton of arthropodsChitin also provides structural support for the cell walls of many fungi

CARBOHYDRATES Check your Understanding

-Milk contains carbohydrates lactose and galactose.-Fruits contain carbohydrates fructose-Potatoes contain carbohydrates starch

1. What is the source of energy for these carbohydrates?

2. What function do these carbohydrates serve in living things?They get energy from sunlight

They provide living organisms with energy

STUDY SKILLS LESSON 1

The FRAYER MODEL - artist's delight!• This graphic organizer helps students to learn new vocabulary by not only defining the term in their own words, but

contextualizing it through authentic examples and visual representation. ESSENTIAL ACADEMIC VOCABULARY – ALGEBRA or GEOMETRY • ALGEBRA STUDENTS• Algebraic expression• Equation• Evaluating an algebraic expression• Simplifying an algebraic expression• Solving an equation • GEOMETRY STUDENTS• Congruent transformation• Parallel lines• Perpendicular lines• Non-congruent transformation• Slope

Reflective Questions for Lab ( 25R)Door Ticket

Copy the question down then answer in complete sentences. Use the heading Carbohydrate Testing.

1. Which substances are used to test for the presence of monosaccharides and starches?

2. What color indicates the presence of sugar? of starch?

Thursday 10-3-13

Objective: Compare the structures and functions of different types of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids.1. Lipid’s Pre-Reading ( web based)-26R2. Lipid Notes (backside)-26R3. Closure: LIPIDS Check your UnderstandingHomework: Study daily ( quiz Monday, test, 10-15)

2. Lipids contains carbon, hydrogen, and oxygen in different ratios than carbohydrates.-The components lipids consist of are a glycerol and fatty acid

used for stored energy, insulation, protective coatings, cell membranes and as hormones all are insoluble in water (hydrophobic) steroids are also lipids mainly seen as fats, oils, and waxes.

Glycerol Fatty Acid Chain

• Can be saturated where all the carbons have a hydrogen attached at every possible spot. No double bonds (usually solid at room temp)

• Can be unsaturated carbons are double bonded resulting in a kink in the carbon chain (usually liquid a room temperature)

• Polyunsaturated when fatty acids have more than one double bond (peanut oil)
