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 24R
1. Closure/Clean up
Homework : 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) – 25L
2. Finish Properties of Water Lab ( you need TWO stations plus your web-quest
finished
3. 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=sugar
fructose=fruits
galactose=milk
D. disaccharides- linking two
monosaccharide's together
E. polysaccharide - many sugars formed by
joining monosaccharide
-Excess sugars can be stored as starch
1. 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 arthropods
Chitin 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?
They get energy from sunlight
2. What function do these carbohydrates serve in living things?
They provide living organisms with energy

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)-26R
2. Lipid Notes (backside)-26R
3. Closure: LIPIDS Check your Understanding
Homework: Study daily ( quiz Monday, test, 1015)
2. Lipids
contains carbon, hydrogen, and oxygen in different ratios
than carbohydrates.
-The components lipids consist of are a glycerol and
fatty acid
Glycerol
Fatty Acid Chain
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.
• 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)
