Bad astronomy

i thought the sun blinding the astronaut was true i was right because the sun close enough can cause blindness. i also thought that it was possiblew to track a meteors path. this is also true tho it takes a long time for the data to be calculated

i thought the speed of the comet was also fake. i was correct, a comet would be moving way faster than what was shown in the movie. another thing i thought was fake was the size of the tidal wave. i was wrong though a tidal wave could easily be that size from a comet

Animals Predict Weather

One of the things we will examine is a widely observed (though scientifically unproven) phenomenon -- even though the tidal wave killed more than 200,000 people, almost no wild animals perished with the exception of caged or confined animals within the wave's path. Observers report that the animals seemed to have some warning, whether by several hours or just seconds, that allowed them, and the people who heeded those warnings, the chance to find safety. Let continue on and look closely at this animal phenomenon to see if there's any fact behind the fiction.­ ­
Potential theories suggest that the animal's acute skills of perception, even a kind of sixth sense may have alerted them to the approaching tsunami. It may even be something as simple as their keen sense of hearing picking up on the sound of the approaching wave while it was still far enough away to give them enough time to head for higher ground. It has also been suggested that the animals may have been able to pick up on resulting vibrations or changing air pressure as well.

It has long been believed by many that animals have a keen sense for earthquakes, storms and impending disasters and can therefore predict their arrival. I myself, as well as I'm sure many of our visitors, do themselves have numerous stories about their pets and their abilities to predict dangerous storms and quakes.

These animals can predict weather

That is the gland in the animals brain that predicts weather.

Climate

The first expiriment we did was that testing the conductivity of different materials to heat. black soil conducted the most heat. i expected this result because of its color and density that it would absorb heat better than sand and water.

We measured the effects of heating the atmosphere in certain conditions and situations. we did get the rsult we expected the black dirt with clouds absorbed the most heat. this is because the clouds trapped the heat causeing it to grow warmer than the clear bottles where heat could escape from. the black soil was also a better and faster cionductor than the snad and the water it trapped the heat the best and the fastest.

Our small scale labs help us understand the earths atmosphere very well.It does this beacuse using bottle and paint as clouds and ozone we can accuratly and easily understand how our atmosphere heats up and stays warm. the dirt sand and water lab helps me understand why some areas of the world are warmer than others based on the ground they have. it has helped me understand that not all surfaces heat equally and different surfaces heat up faster tha others.

climate change

Climate change is a problem that is affecting people and the environment. Greater energy efficiency and new technologies hold promise for reducing greenhouse gases and solving this global challenge. EPA's website provides information on climate change for communities, individuals, businesses, states, localities and governments.

Gases that trap heat in the atmosphere are often called greenhouse gases. This section of the EPA Climate Change Site provides information and data on emissions of greenhouse gases to Earth’s atmosphere, and also the removal of greenhouse gases from the atmosphere.

Sewer treatment plant

At the sewer treatment plant we learned about the sewer system. we learned that there is a big filter that takes out all of the solid matter and large inorganic objects. the water pumps through big pipes and goes into large tanks where microorganisms eat away the waste and organic matter. after that the waste is treated and pumped back into the river as clean water.
recylcling is good for the environment i have always recycled and i will continue to because it is good for the environment.

town construction

1)Mrs.Byrely is a secratary
2)the city improved our dranage system to filter the bigger materials out
3)the rain water is filtered ouyt instead of all flowing into the island
4)there should be less tds in the water
5)i thought the most interesteing thing was the pourous parking lots
6)my bio bottle is growing well the control and organic are growing the best
7)we are doing proccesed vs organic foods and which has a bigger impact on the watershed
8)i have it partially completed

Lexus Challenge Bio Bottle

our group chose to compare organic and proccesed foods.
We plan on taking one bio bottle putting organic foods into it. then taking the other bio bottle and putting processed foods into it. we will measure the water for different chemicals and see what hapeens to the wate r with each type of food.
in our bio bottle were testing or organic and prccesed foods. were testing them to see which has a greater effect on the water below. we are expecting the processed food to have more of a negative effect in the water due to the chemicals. while we expect the organic food to have more of a positive effect on the water.
our action project and river project are connected. they are connected because everything we throw away someway gets back to the water. so we are seeing what type of foods have better impact on t5he water when it gets there. people should eat more organic foods if it has a positive or less of an effect than that of the processed foods.

Eaton Rapids Water Treatment Center

Yesterday we went to the water treratment plant. they showed us how water was made to be drinkable. they take the water from underground wells. after they take it they put in chemicals such as chlorine to kill of all the bacteria. they take water samples of our school once a month. they take many field samples from all over the town. the water is stored in water towers that gives us the pressure. it is a good place to work apperantly.

City Water

City water either comes from nearby bodies of water or from underground aquifers. it is prosseced in water treatment plants where it removes harmful bacteria so that we are able to drink the water when its been cleaned.
Sewage can be treated close to where it is created in places such as biofilters or septic tanks or collected and transported by large networks of pipes to a municipal treatment plant. Industrial sources of wastewater often require specialized treatment processes.

how is the sewer water filtered?
how long does it take to filter the sewer water?

Footprint Blog

Sure good for all ages
My footprint  is 32 out of 100
Recycle more drive less and  use less electricity
If our whole community used less resources then we would have a smaller impact on  the water shed. we can  do this by  recycling more and using a compost  instead of throwing everything  away  which pollutes thewater as it goes into rivers and lakes.
