The Earth is the 3rd planet from the sun. About 4.54 billion years ago it was formed. Everything in our solar system rotates around the sun.
"The immediate galactic neighbourhood of the Solar System is known as the Local Interstellar Cloud or Local Fluff, an area of denser cloud in an otherwise sparse region known as the Local Bubble, an hourglass-shaped cavity in the interstellar medium roughly 300 light years across. The bubble is suffused with high-temperature plasma that suggests it is the product of several recent supernovae.^[105]
There are relatively few stars within ten light years (95 trillion km) of the Sun. The closest is the triple star system Alpha Centauri, which is about 4.4 light years away."  (1)



Big Bang Theory: The big bang theory states that a very long time ago there was nothing. then this big "bang" came and it ecxpanded and cooled going from very small and hot to the size and temp of our current universe. It contunes to expand and cool. They say there was no actual explosion, only expansion. This is why galaxies appear to be moving away from us. "the abundance of the "light elements" Hydrogen and Helium found in the observable universe are thought to support the Big Bang model of origins."   (2)
How old is the universe:
"Until recently, astronomers estimated that the Big Bang occurred between 12 and 14 billion years ago. To put this in perspective, the Solar System is thought to be 4.5 billion years old and humans have existed as a genus for only a few million years. Astronomers estimate the age of the universe in two ways: 1) by looking for the oldest stars; and 2) by measuring the rate of expansion of the universe and extrapolating back to the Big Bang; just as crime detectives can trace the origin of a bullet from the holes in a wall." Life cycle of a star depends on its mass. High mass stars are brighter and low mass stars are dimmer. A star like the sun has enough fuel to burn for about 9 billion years, a star twice as big can burn for about 800 million years.   (3)

The Water Cycle

http://en.wikipedia.org/wiki/File:HydrologicalCycle1.png


This process has many steps. Precipitaion- condensed water vapor that falls to earth. Canopy interception- precipitation that is intercepted by plant foliage and evaporates back to the atmosphere. Snowmelt- Runoff produced by melting snow. Runoff- The way water moves across land. Infiltration- The flow of water into the ground. Subsurface flow- Flow of water underground. Evaporation- Transformation of water from liquid to gas. Sublimation- Change from solid water to water vapor.  Advection- The movement of water through the atmosphere. Condensation- Transformation of water vapor to liquid water in the air. Transpiration- Release of water vapor from plants and soil into the air.

Rivers and Streams:
There are 3 main types of streams. Ephemeral-Streams regularly exist for short periods of time. Intermittent-streams flow at different times of the year when there is enough water. Perennial- streams that flow year-round. (2)
When humans build things it effects rivers and streams because building materals get dumped into the water, things may block the flow and pollutants get thrown in killing all life in and around the water. The highest threat levels are in the United States and Europe.  Globally between 10,000 and 20,000 aquatic species are at risk because of how bad humans treat wetland. The worlds least affected rivers were the ones farthest away from populated areas. (4)

"Here we focus on the local hydrologic cycle for a watershed. The important factors are precipitation, evapotranspiration, overland flow, infiltration, groundwater flow and stream flow, along with special manifestations of each referred to, respectively, as baseflow (groundwater flow into streams), runoff (different authors use different definitions) and subsea flow (deep groundwater flow directly into the adjacent ocean or estuaries). The following notation will be used to represent the associated watershed components:" (3)

Components of Local Water Cycle P = Precipitation Qswi = Surface water in (e.g. stream flow into the watershed, and overland flow that enters directly) Gin = Groundwater flow in Qswo = Surface water out (e.g. stream flow, and overland flow that exits independently of streams) ET = Evapotranspiration Gout = Groundwater flow outDS/Dt = Change in the volume of water in storage (S) per unit time

MSU

Five things i learned at the planetarium are...
1. the cup of the big dipper points to the north star
2. the north star doesnt move
3. the sun isnt the brightest star
4. when u look into space your looking into the past
5. the constellations dont really look like what theyre called.


i didn't go to the cyclotron.


i enjoyed going to the international center and getting ice cream.
and i would go on a day it wasnt raining.(:

snow storms

Where:  (1)
-anywhere temps get below freezing.Mostly in Northeast U.S.A.

Why:(1)
-dominant varieties of precipitation are formed at very low temps, ground temps have to be low enough for ice to form.
Impact: (2)
-schools close, cars cant drive safely, people get snowed it, stores and businesses close,most plants freeze and die.
Technology:(2),(3)
-announced over the tv, radio, email, text messages and it is announced before, during and after the storm. Some technology used to predict snow storms are rain gauge (which shows how much rain or snow), barometer (which measures air pressure, it decreases when wet and increases when dry), thermometer(which tells temp).

Great Lakes in the Regional Context

Summary:
On the river i learned it has a PH of 7.5. which is pretty good considering all the variables that go into and out of the river.  Our Q-value  is 10.23. And the total Q-value is about 83.3635. If more people recycled then less things would end up in the river that arent supposed to be there, therefor the water would be cleaner and maintain life easier.

Questions:
1.The biggest lake in terms of volume is Lake Superior.
and the smallest is Lake Huron.
2.Lake Michigan is more urban and Lake Superior is more rural.
3.Lake Huron has the longest shoreline.
4. We can best manage the ecosystem by taking care of it, not throwing away your trash on the ground, and being respectful of life.
5. Two types of pollutants that affect our project would be
animal (or people) waste. We tend to just throw our things on the ground and bacteria and viruses find their way into the ecosystem. Another one would be detergents, pesticides and fertilizers, because they are toxic to our environment.

Preliminary Questions:

• The water we use from our houses goes into the water supply.
• Runoff water 

 is the water flow that occurs when soil is infiltrated to full capacity and excess water from rain, melt water, or other sources. It goes into the environment.

• Yes, it does. Yes it should because it all needs to be filtered again. And it can all be harmful
• When it enters from a localized point is point. non point comes from rain.
• A watershed is something that controls water pollution. 

what i learned on the nature walk

On the nature walk i learned the different types of trees. And saw lots of different types of bugs.

When people throw things into our environment it affects the ph of waters, bc of the chemicals in the waste.

our project is recycling of electronics and we are testing the PH of the water.

we are doing really good on our project, we are on top of things and where we should be work wise.

i manage the group, and pass out recycling boxes and talk to the people to get things started.

what i want to learn in global science

I would like to learn how to take care of our environment a little better. Stop pollution and find green ways to do everyday things.  And learn how to reuse more things than we do now.

what i know about the internet and technology

The uses for internet are increasing greatly. schools and businesses use it to do their work. People use it to communicate with friends and family in other cities and even countries. It keeps advancing everyday.
Technology is used on a daily basis by everybody.
We went from simple machines to really elaborate things like cell phones, ipods, ipads, laptops  etc.
