Human Impact:
12.
Nonrenewable resources are considered to be fossil fuels and nuclear. United States rely on a lot of fossil fuels including coal, oil, and natural gas. We use these to create energy, but it destroys our atmosphere also. In return there are renewable resources like solar, wind, water, and biomass. The renewable resources are a lot better for the atmosphere and it is either direct or indirect with the sun. Solar is directly used to heat and light up homes or buildings. Wind turbines are used from the suns heat which creates the wind to move the turbines. Energy can change form through Earth Systems through internal or external sources of energy which both creates heat. Most of the changes are from the sun. The sun creates the heat which creates the Global Science.With the Earths surface and atmosphere heating up by the sun, the ocean currents and winds are created. The heat from the sun in transferred through the atmosphere by three mechanisms, Conduction, Convection, and Radiation. Radiation is the warm feeling on sunny days when you go outside and tan, have fun with friends, or play sports. The transfer of heat energy by electromagnetic waves is Radiation. The transfer of one subject to another is call Conduction. Copper or metal can be a conductor. When you take a piece of grass and set it on the electric fence and you get shocked. The grass is the conductor. The electric energy goes through the grass and into your body. A safety pin over the flame is the same way. The safety pin absorbs the heat and the molecules will transfer over to the hand holding it. The The rate of heat transferred determines how well a conductor is. A piece of grass wouldn't be the best conductor, metal or copper would be a better choice. Transfer of heat through the movement of water or air is Convention.

20 time
I worked on my final project for English and Digital Media. I need to get pictures and put them in a slide show. But it's difficult to find the ones I want.

Water Request
1. Water pollution is when bodies of water get contaminated. The different types of pollution are, surface water pollution, oxygen depleting, groundwater, nutrients, microbiological, suspended matter, and chemical. When oceans, rivers, and lakes get polluted it is called surface water pollution. When to much biodegradable material is added to the water then the number of microorganisms increase and use up the the available oxygen depletion. Pesticides cause groundwater pollution. Nutrients can be found in waste water and fertilizers, and these can cause excess weed and algae growth. Microbiological is natural water pollution by microorganisms. Suspended matter is when the pollution isn't able to be absorbed in water because the molecules are too big. Chemical pollution is from agricultural and industrial work that runs off into the water.
2. Point source is a single source and a non-point has many sources.
3. Three causes of pollution is underground leakage, sewage, waste water, and radio active waste.
4. Suspended particles can often reduce the amount of sunlight that reaches the water disrupting growth of plants.
5. To help improve pollution, turn off tap, don't throw paint oils down the sink, environment friendly house products, don't litter, plant more plants, septic tank, ozone waste water treatment.

Solar Energy
March: 332 kilowatt hours of energy was produced. 6 trees were saved and there 110,666.667 batteries.
April: 402 kilowatt hours of energy produced. 7 trees were saved and 134,000 batteries.
Today: 3.72 kilowatt hours of energy was produced.
Our solar panels are pretty cool. We don't learn much about them or get to see our solar panals so we don't know how well they work and how much energy it saves. I think we should put it more in class or even have a class about it.

20 Time
1. We got almost all the information and pictures back from the seniors.
2. Having too much information and not being able to fit 14 seniors on a page.
3. It's newspaper work, so I don't learn much about myself. The senior page is harder because it is difficult to rely on others.
4. Putting the info on the page. We gotta ask the seniors another question though since the paragraph is out.

Footprint: Global Science
1. Http://footprintnetwork.org/en/index.php/GFN/page/calculators/
2. No it's not a good cite for kids unless they have hit middle school because then they won't be able to understand. Younger kids would be able to use it with a parent. It was a easy cite for me to use besides i don't know the acres I live on.
3. 4.5
4. Yourself: short showers, turn of water when brushing teeth, turn off unneeded lights.
The School: use one set of lights, turn down heat, keep computers off
The Community: car pool, ride bike more, keep lights off at night (businesses)
5. The video said to buy locally because it doesn't create as much of a footprint. The closer we buy things like at market or farms and the more we grow in our gardens at home, the more plastic or waste we save as well as we don't have to waste gas for fruits and veggies.

20 time
The group can not focus and the video does not make any since. It's a real struggle. The superhero videos are a lot of fun depending on the group.

20 Time
Kat and I decided to start the Senior Addition for our 20 Time.
Today we went around and ask some of the seniors questions for their Senior Sign Off

Mars Movie Post
1. There was oxygen on mars which means there is carbon dioxide too.
I didn't think mars would have oxygen.
Dr. Plait says that there is a low carbon dioxide in the norther part of mars.
2. The fire that went on in the ship, it was difficult to put all of it out alone.
I didn't think that a fire could be started out in space with no oxygen.
Dr. Plait says that it could happen but when the girl goes to put the fire out she goes backward, it was accurate.
3.When the solar flare catches the ship on fire, it didn't seem that hard to put the fire out and solve the problem.
I thought it seemed too easy but was really interesting on what all happened.
Dr. Plait says that in real life it would of been a lot more complicated.
4. The escape pod hit the ground and got destroyed.
I thought the escape pod would be more secure and safe.
Dr. said the pod fell to quickly, the gravity in Mars is less, which would make the pod bounce higher and slower
5.The gravity immediately dropped when the girl turned the main power back on.
I thought that it was unrealistic for the gravity to come back quickly when it took awhile for it to go away.
Dr. said that the gravity wouldn't just go back on, it would take time for it to actually take affect. She wouldn't just fall to the ground like everything else.
Egg and Equinox
-I thought an egg could balance at a certain time through out the day not just on a certain day.
-It only happens on the first day of spring because the earth axis is perpendicular to the sun.
Dark Side of the Moon
-I thought the moon really had a dark side. That is why people say the dark side of the moon.
- The moon has no dark side, it looks like it to us only because we cant see that side. There is no dark side only a far side.
Why is the Sky Blue
- I thought the sky was blue because it is reflecting blue light. Kind of like how grass looks green, it doesn't absorb the green light.
- The suns blue light scatters which causes the sky to be blue.

Global Science Questions
I know very little about computers and technology. I am not very comfortable with using macs because it is different then my lab too and the school computers. I am able to design things using photoshop but when there I have to put together something or need to do something fancy I am no able to do so. I am not a techno person.
I would like to know more about the out space and the alignment of the stars and be able to spot the Big Dipper and the North Star. I like learning about the plants and sun, so being able to know information about that would be fun. I would like to make the earth a better and safer environment for animals and plants.
