There are two different types of forms of energy Potential Energy - which is stored energy in something or another and Kinetic Energy -  Which is working energy or activly moving or being used energy.

You can also classify energy as renewable energy, such as Wind energy or Sun energy, and there are non-renewable energy sources such as trees, coal, oil and others.

This is my glog of motion!!!

How many were school based, your own interests or set by the challenge? I wrote 22 school related articles and 1 that was my own intrest and 6 that were set by the challenge

Which post received the most comments? Why do you think that happened? my macroinverabrae blog and my 7 random facts i think that happened because  they are the most interesting/the thing they can nonnect to.

Which post did you enjoy writing the most and why? I enjoyed writing 7 random facts the best because it was nice to write random facts

Did you change blog themes at all and why? yes because i wanted to be able to customize my blog

How many widgets do you have? Do you think this is too many or not enough? I have three and i think that is just enough.

How many overseas students do you have on your blogroll? there are about 4-6 class's overseas in our blogroll

6.1 I also learned that if the weight is greater it increases the friction

6.2 If the surface is smaller it also increases the friction

6.3 some objects or surfaces increse or decrease the frictions pull.

2. We measured sliding friction by pulling a block along by a spring scale which measures friction because friction pulls backwards and so, if the block is harder to pull, that much friction that is making it harder, so that is how we measured it.

3. we controlled variables by changing one thing, such as the weight, and then kept all the other things the same, slope, times, length of pull, surface area, surface type, etc.

Thanks!

Elastic force is a force (duh) that is created by an object that has changed shape but tries to go back to its old form. The best example of this is a rubber band, but it happens in other opbjects such as some springs, and others. For instance if you were trying to mave a cart with a rubber band there are two options you have. 1 to tie the rubber band to the cart and pull it (this way does use elastic force but not much) 2, to make a slingshot out of the rubber band and launch it (this way uses a lot of elastic force but cannot direct it much).

What is gravity?

gravity is a force that acts on objects to pull it twards large objects of mass, such as the moon, the sun, the eath, etc. it is what makes you have weight (the difference between mass and weight is that mass is the amount of stuff in an object and weight is how much gravity pulls it down.)

Did you know, in 1930 our machines emmited or gave off ( for a small nieborhood) about 134 pounds of carbon dioxide. That may seem like a lot, but for the same size nieborhood in 2010 our machines emmited about 964 pounds of carbon dioxide!! now THATS a lot.

ENERGY

Did you know:

insulation helps conserve energy by keeping out or in heat and cold so you dont have to use as much electricity heating or cooling buildings.

dangers to yourself (yes you!) from electricity

flying a kite near wires

putting objects near electircal plugins

using electricity near water

putting metal in electrical appliances

pull things by their powercord

putting burnable objects near lightbulbs or lamps

dont put anything in an electrical outlet

What fuels gives off more electricity 

wood - 2.59/lb

coal - 2.48/lb

fuel oil - 26.4/lb

gasoline - 23.8/lb

LP gas - 12.1/lb

electricity from coal - 2.37/lb

electricity from oil - 2.14/lb

electricity from natural gas - 1.32/lb

==========

 I know that batteries store energy.

I know that batteries have acid.

I know that batteries have to elecrical flow points.

I know that batteries have limited charge.

I know that some batteries can recharge and some cant.

WHAT I WANT TO KNOW

===================

 I want to know how batteries store Electrical Energy (E.E.).

WHAT I LEARNED

==============

I learned that when a batteries is plugged in to charge the lectrical energy travels along the wire and changes into stored chemical energy which, in a different complate circut turns back into energy, and depending on what it is powering turns into light and heat, or mechanical energy.

I live in washington and where I live there is TONS of rain, not very much sunshine, but lots of greenery, such as ferns, salal, trees, etc. and also there is lots of ponds lakes river, ect. where I live.

 WATER QAULITY PARAMETERS

==========================

D.O

The average D.O. for this year is 8.125 mg/l

D.O stands for dissolved oxygen

5.0 and up to a certain level (?10?) is good, So it is good.

It is good for humans, and fish. Air is the main way for

D.O to get in the water. Plants and help the D.O level too.

pH

this years average pH is 6

pH stands for positive hydrogen

0 and 14 are pollution. So it is very good. pH is a Measurement

Of acid. The acid level is multiplied by ten each level you

Go up or down from 7 (neutral).

Turbidity

This years average turbidity is 44.7 NTU's

Turbidity is the measurement of cloudiness and clearness 

It does not mean much because they experimented with

how to change the turbidity of the water. But other wise it

is good. Because when the water is clear that means that there

is good turbidity. 0-50 NTU is clear and therefore good.

Nitrates

This years average Nitrates is 2.3 mg/l

Nitrates are most of Nitrogen

Stable nitrates are 3 oxygen and 1 nitrogen in an atom. Unstable nitrogen is 2 oxygen and (unknown) Nitrogen in an atom. Low levels are good, high levels are bad. Nitrogen cycle is air, bacteria, plants, animals, dirt, last air/dirt. Nitrates affect algae and bacteria so if there is too much fish will die because there is too much algae and bacteria.

Ammonium

This years avergae ammonium is 1.6 mg/l

That is a bad number and is problaby not possible as there are salmon in our creek

It is a colorless bad smelling gas. It’s made from bacteria. The atom is made from 1 nitrogen, and 3 hydrogen. It makes very good fertilizer and cleaning products. It is found in animal manure. People get it from inhaling it. No numbers are good except for 0. But things close to 0 is pretty good too such as 0.1 or 0.2.

Flow rate

This years average flow rate is 1972.8 g/s

Medium speeds are good, slow is good but to slow is bad because algae grows and is not hindered by flowing water, fast is bad because fish can’t rest and young can’t swim.

Temperature

This is my parameter ( I measured it).  Some of the variables that affect the temperature of the water are: The color of the water (changes how much heat it absorbs, the darker the more heat absorbed), the depth of the water (the deeper the colder because they take more time to warm up), The amount of shade (it prevents parts of the water from getting warm from the cold), Nearby climate (Example: when the climate is cold the river is more cold then it would be in a hot climate) The seasons (Example: when the season is winter the river is more cold then it would be in summer) the temperature of the water coming into the water source (such as just un-frozen water running into the stream would cool it down or basically make it colder), the amount of water ( the more the slower it cools down). It affects the dissolved oxygen level in the water because when air is in water and it becomes warm it is less likely to dissolve, photosynthesis of aquatic plants because when the heat increases the rate of photosynthesis goes up until 32 degrees Celsius or 89.6 degrees Fahrenheit and then level off and decreases and the temperature increases past that, metabolic rates of aquatic organisms because when the heat changes so does their metabolism and they use more dissolved oxygen and they have less dissolved oxygen cause they are using more.If the temperature is too high or low the fish in any stage could die.It affects humans because some people make their living from fishing so if they died then they would be poor and no one would be able to eat any fish and if they relied on fish for food they might die.It affects vegetation because the plants in and around the water would not get the fish’s droppings that may act for fertilizer for them so they would not grow as well, and bugs would eat them more because there would not be fish to eat them.

This is what we measured the stuff with.

So all this tallys up so that eventually Chimacum Creek is...........................

oops! you went to far!!! (unless you were heading to other blogs :)

Recently the ENTIRE sixth grade in our school went tree planting. We went there to plant trees because we wanted to help the salmon. Trees help the salmon by providing more dissolved oxegen, hiding spots (leafs), and when the die if they fall in the river they create a slow moving part which is good for laying eggs, good for bug habitat (food) and a place to rest .We split into two types of groups and changed half way through. One was the digging team which first made a circle indent, smash the dirt into small chunks and put the dirt off to the side. The other type of team took a tree and one person held it and the other put in the dirt. I am guessing that about half of them had fun, but I did. I enjoyed going there (including the walking) but also the game was interesting, and also I enjoyed planting trees. Thanks to all the vonenteers for helping out especially Chawncey. (if I spelled his name wrong leave a comment so I can fix it).

Perfect numbers are number that, when you add up all of the factors, not including the number, you make that number.

You probably still dont understand. For example, the first perfect number is 6. So, the factors of 6 are: 1,2,3, and 6. but you take away the 6, because it is the number. That leaves, 1, 2, and 3. 1 plus 2 plus 3 equals 6. beacuse it does, that makes it a perfect number.

One more interesting fact about them is that the last number of each perfect number is either, from 6 to 8.

The First ten perfect numbers:

1                                                                                                                                6

2                                                                                                                              28

3                                                                                                                            496

4                                                                                                                         8,128

5                                                                                                                33,550,336

6                                                                                                           8,589,869,056

7                                                                                                       137,438,691,328

The Adult Salmon

the salmon adult livs in the salt water and are mostoften silver. they are 14 in. to 5 ft. long, and are about 2 to 125 pounds in wieght. DANGERS:they have dangers from: Orca whales, Sea lions, and seals are some of its predators. humans are also hunters of salmon. NEEDS: they need small fish, srimp, squid, and other tings to eat.

The Spawner

the spawner are often multi-colored and come in a large variety of colors. this is the stage of thier life where they head back up the stream to lay their own eggs and restart the cycle. DANGERS: dangers to spawners include: fishermen, and predators such as bears, birds, and wildcats, and some of the things they faced going down.NEEDS: they dont really need much but they do need, fishladders to be able to bypass hydroelectric dams, and clear clean water and they can also climb waterfalls to get higher up  the stream.

The parr/smolt

The parr is like a fry but will or has undergone smoltification which gives them a type of camoflauge ( this occurs after a while of traveling downstream). They have also grown to about five inches and are the last stage of the salmon life cycle before they have traveled into the ocean. DANGERS: the dangers to them include: Hydroelectric dams ,gulls and other birds of prey, and pollution from farms, factories, and citys. NEEDS: they need non-polluted water and someway to bypass hydroelectric dams and they need to have undergone osmoregulation

The fry

a salmon is a fry when is was an alevin but has used up thier yolk sack. most are silver and they start to move in schools and hunt for themselfs. they eat small insects (macro inverabrates(see blog)) and zoplankton. DANGERS:the danger to them are:having no food, non-cool water, gravel with sediment and many types of birds, and other predators, erosion, and pollution are some of the treats to the frys. NEEDS: they need:food, cool water, sediment-free gravel,trees (for shade and to keepback sediment and help prevent eroision.) and plants.

The alevin.

the alevin are the stage of when the eggs hatch. there are slightly transparant and come in some differant colors. they have a small yolk sack attched to their upper body. DANGERS: some of the dangers to alevin include: Gulls, Dippers, Sculpins and other predators, and another danger is having no gravel or other substance that they can hide in and being crushed. NEEDS: they need gravel or some other substance to hide them and they also need most of the smae things aas eggs so they need plants to help prevent soil erosion and cool, clean water and trees to provide shade to cool the water, but they dont need food because they have the yolk sack which provides food for about a month.

the eggs of the salmon.

the eggs are orange and have a little black dot in the center.they are laid by a female salmon spawner which creates a shallow pit in the gravel called a redd. the female then lays and fertilezes the eggs, and then covers the eggs with gravel that allows th eggs o still get water. DANGERS: some of the dangers to eggs include: hikers, loggers, fishermen, livestock, and wild animals all somtimes crush or destroy the eggs and/ or the redd. NEEDS: eggs need cool, clean water and tress to provide shade to col down the water and to hold the soil from eroding and smothering the eggs.

The first-

This is a stonefly. It is very sensitive to water pollution. It is dead because of a change of temperature or pollution.

Our second-

This a stonefly but it is a LOT smaller. It is very sensitive to pollution. It is also dead because of temperature or pollution.

Our third-

This is another stonefly, but it is alive! I do not know why.

Our fourth-

This is a scud. It is fairly tolerent to pollution. It is alive because it is not really affected by change of temerature. So these are the ones we found. We are doing this to determine how healthy our creek is. To score we gave 4 for very sensitive to pollution, 3 for sensitive to pollution, 2 for fairly tolerant to pollution, and 1 point for very tolerant to pollution. So ours would just be 10 but the class's is 21! Which is very healthy I believe. And now we are comparing it to a different creek, Yellow Jacket creek. Yellow Jacket creek got 25 but even though we close, Yellow Jacket looks like it is a lot cleaner and clearer than ours. Oh I forgot to tell you about biological integrity. biological integrity is "the capability of supporting and maintaining a balanced, integrated, adaptive community of organisms having a composition and diversity comparable to that of the natural habitats of the region". says http://www.epa.gov/bioiweb1/html/biointeg.html. An indicator species is a species that can be tested to well, test an envirorment. Benthic Macro's are a good indicator species because if the very sensitive ones that cannot stand pollution ,they die in it, are alive then it is not polluted and so is healthy. Salmon and trout are not good indicator species because some of them may have just come from salt water or a different stream/lake or other water source and that water source may not be polluted. Macros are good for determining biological integrity of streams and creeks because "they are suspectible to degradation of water sediment and habitat" says http://www.epa.gov/owow/watershed/wacademy/acad2000/rbp/6benthic.html, which makes them good indictators of their enviorment healthyness which, happens to be the stream or creek in question.
