Water, Water, Everywhere!
Water, Water, Everywhere!
Welcome Back! Feb. 19, 2013
Get Going: Reflect on the Exam you just took. What are some things you could have done to do better on the exam? What ways did you study or could have used to study better?
Turn this in the paper tray
Take a moment to fill out your agenda for this week
Agenda for Today
1. Review Microbiology Exam
- Write down the RIGHT answer.
2. Place Exam in your crate folder
3. Organize your papers
4. New folder, New stuff, New Unit
What is Hydrology?
What is our first standard?
UNDERSTAND the hydrosphere, and the IMPACT of humans on local systems and the EFFECTS of the hydrosphere on humans.
What is our Second Standard?
UNDERSTAND how organisms INTERACT with and RESPOND to biotic and
abiotic components of their environment.
What should go in our folder pockets?
How should one take good notes?
How does one study?
What's up with the VOCAB section?
Properties of Water
tightness across the surface of water that is caused by the polar molecules pulling together side by side - Keeps bugs from sinking
Held together/attracted by an electric force
Draw this picture in your notes
Take notes on this video
polar molecules sticking together from all sides
How many pennies can I drop in my cup of water before it overflows?
Mass per unit of volume
1.0 g/cm3 or 1.0 g/mL
Ice = less dense than water because it occupies more space
We can compare densities to predict whether an object will sink or float in fluid.
Which one has a higher density?!
Ex: Iceberg in water floats
Hydrogen bonds - 39 F
The ability to float
The force that is exerted by a fluid on a submerged object
makes an object feel lighter
Draw your arrows little and big
Archimedes Principal states: buoyant force on an object is equal to the weight of fluid the object displaces
Buoyancy Part II
Properties of Water Continued
water's ability to stick or be attracted to other surfaces
the positive end of the water is attracted to the negative end of other surfaces
You Try it..
Water climbs up things they are attracted to
Combined force of water molecules and molecules of surrounding material
Ex: wicking; water climbing up paper
1 cal/g C -- higher than any other substance including metals!
Water needs alot of heat to increase the temperature because its strong attraction to other molecules.
Rocks heat more quickly than water because it has a weaker attraction
Draw this picture
solution: water + koolaid mix
solvent: water (<-- does the dissolving)
many substances dissolves in water because water is polar
non-polar (no charge) substances does NOT dissolve well in water
Ex: sugar (solid) bleach (liquid)
T.G.I.F. Feb. 22, 2013
Get Going: which would be MOST EFFECTIVE in defending against an epidemic?

Write down the question and the answer in your agenda. I will check them! Be ready to share your answer.
Ok.. We have just a few notes today
Draw and Label Properly - Find the definitions using your book.
Find the definition of these words in your book
Agenda for today... Pay attention so you know what you are doing
1. Station # 1: Wax paper, popcicle sticks, eye dropper, water. Follow the directions given. You may challenge your partner in water hockey once questions have been answered.
2. Station # 2: Dunkin 4 Density - Film Canisters. Read through the directions carefully. You will have to do some math but remember M/V = D
3. Station # 3 Properties of Water Foldable
- Due at the end of class -
4. Earth's water ... copy into your notes. Only use ONE blue circle.
Review of water
Water is the only substance on Earth that occurs naturally as a solid, liquid, and a gas
It is rarely ever pure
Water covers 71% of Earth's surface
97% salt water (not drinkable)
3 % freshwater
77% of freshwater is ice (ice caps, glaciers, ocean)
Availability of water varies with local geography and allows humans to utilize water as a resource
The SUN drives the entire water cycle: condensation and evaporation
Aquifer - large deposit of ground water that can be extracted and used.
portion of land drained by a river and its tributaries
streams, creeks flow downhill into one another and eventually into one river
sends all water into a central river and out to sea
ALL people live on a land that drains to a river, estuary, or lake
affects water quality and quantity downstream
17 River Basins in NC
The topography of the land depends if it flows to the Gulf of Mexico or the Atlantic Ocean
Color this on the map given to you and turn in with your name on it.
52, 337 square miles of surface and underground waters
We live in the White Oak River Basin -1,264 square miles
within 4 counties
Good Morning/Afternoon Feb. 25, 2013

3. Dunkin 4 Density (Station #2)
4. Foldable on Properties of Water (TURN IN)
5. Lab Paper turned in!

Long Term Changes
water collects in hollows
shallow water - sunlight touches the bottom
plants and algae grow here
water collects in the hollows
shallow parts like a pond but also the deep parts where sunlight doesn't touch the bottom (less plant life here)
Reservoir: lake stores water for human use
If there is TOO much algae; it will block the sunlight and the lake will lose oxygen and die.
Tributaries - creeks that bring their water to the rivers
Watershed - land area that supplies water to river system
Divides - ridge of land that separates watersheds
1. nutrients build up in the lake
2. built up over time 3. causes more algae

3 Person Groups
You must keep your group on track and on time to complete the assignment.
This is a HUGE responsibility
You must keep your group in line and on task. You will delegate the work to be shared by all in your group. You are responsible for your groupmates and the job that they are doing.
You are responsible to get supplies needed for your group. In this case, you will be taking the completed notes and comparing them with the teachers. If some things are there that your group did not have you must write them down and bring it back to your group.
Your goal is to make you have detailed notes.
On pg. 74-79 is the section that your group must cover.
There are 3 distinct sections in the chapter and the CAPTAIN should delegate each section to each member.
The timer keeps the ball rolling by paying attention to the time so that all tasks will be completed before the time runs out.
Goal: At the end each of you will have your own set of notes on the Wetlands section. ** I will check to see if you have it completed***
The runner must make sure the notes are complete by comparing with the teacher copy.
When finished -- your group can work on answering the questions on pg. 79 #1-3 together on one piece of paper to be turned in.
YOU NEED YOUR SCIENCE BOOK TODAY

Population: a group of the same species
It is described by 3 things:
1. size 2. density 3. distribution
: crowding causes competition for food, water, shelter, predation, parasitism, & disease.
doesn't matter about size; weather, pollution, wildfires, etc
Other things that can change populations
Abiotic: nonliving (water, sunlight, nutrients)
Biotic: living (bacteria, fungi, plants, animals)
Predators vs Prey
Prey , Predator
Predator , Prey
relationship that occurs when 2 or more organisms need the same resource at the same time

Distribution of freshwater on earth...
What is water mainly used for?
70% - __________________
22% - __________________
8% - ___________________
Draw this in your notes
Distribution of water on earth
draw this in your notes
What is saltwater?
What is freshwater?
- water containing large amounts of salt
-water lacking large amounts of salt
Water has no taste, color, or smell
Water, in nature, appears as a solid, liquid, and a gas at normal temps on Earth
Gas: water vapor
Liquid: rivers, etc
Solid: ice- it freezes and expands : less dense than other liquids
Imagine if Ice froze from the bottom to top instead....
Polarity allows it to have dissolving ability
ex) how trees bring water from its roots to the tallest leaves
