My group was wondering if MHC had ears. so we tested to see what kind of music they liked. our first trial was with the song "cinemas" and "call me maybe" and they seemed to like cinemas better. then the next day we tried the song "boyfriend" and "drummer boy" with different cockroaches and they seemed to like the song boyfriend better the drummer boy. then come to find out the cockroaches do have ears.!(:

Did you know that madagascar hissing cockroaches are native only to the island of madagascar. If you see them anywhere else someone brought them there. Also males are territorial, tey wil fight any intruders. they fight by butting heads. female hissing cockroaches only bread once in a lifetimes.and they grow 3-4 inches in length. baby mhc are the length of a small watermelon seed.

what i liked about odyssey was we got to hangout with friends around the camp. and that was my favorite part. I also liked playing ping pong and i had an okay time on the hikes. but the 9 mile hike was hard on the beach.
What i dont like was some councilers were very rude for no reason and then they complain about us not being nice. Then we had to have a person come with us to go to the cabbins.
I wish i could of changed the food. im glad we had her come an im very thankful she came. and i wish we got more foooood!!(:

My group wanted to see if the snail preferred darkness or light. So we made a kittle box and out some peanut butter in the box. And then we put peanut butter outside of the box for the light. I thought the snail would go to the light. The first snail went to the light. But started going to the dark and then changed and went to the light. The second day with a second snail he didn't choose right away. He went back and fourth from dark to light but ended in the light.

I know:
they have one foot
their gross
their slimy
they have a shell
they cant jump

what i wanna know:
horses galup, snakes slither, babies crawl and walk, what do snails do?.

My group did an expirement with rye grass. We tested different waters. We had salt and sugar water. Five vials for salt and five vials for sugar. One vial for each, salt and sugar group was ragular tap water. Each vial started with 20 ml of tap water. Then each vial we would add five ml of the product. So for salt, vial one just water and vial two had 5ml salt. Vial three 10ml salt. Vial four 15ml salt. Vial five 20ml salt. Then we added the same amout of sugar to the other five vials! I learned a lot of information about osmosis and what it was and how its a big part of the plants life. I learned why the salt effected the rye grass. "Osmosis." Wikipedia.

I made a baby with Cam Gigandet. And i found out that my baby will have brown hair, blueish green eyes and attached earlobes. And definitely both of our good looks(;

I think that the school water fountain is not safe to drink from! The bacteria on the water fountain next to the gym is discusting! I dont think i will ever drink from out school water fountains again! The lunch table is clean enough to eat on. The toilet seat is the worst! There is a lot of germs and bacteria! Juding by the amount, I will be very uncomfortable to go to the bathroom. And, i will be squating from now on. I beleive that there is poop particles on the toilet seat.
Our evidence is the bacteria in the petri dish, and these photos. My team forgot to just do a zig zag on about 2 of the objects so some of the bacteri could have grown or just been from something else. I feel like i understood everything.(:

Cells divide/multiply using a large array of steps. First the chromosome splits into two identical chromosomes. Next the genetic material in the nucleus of the cell begins to thicken and shorten. The chromosome copies are held together at their centers so they form a sort of 'x'. Then the 'x's line up at the center of the cell. Then the copies separate, and each copy of the chromosomes are moved to either side of the cell towards each nuclei. To finish up the cell division the cytoplasm pinches at the center of the cell-dividing it in 2.

Interphase: The busiest stage where the cell is preparing for the division.
Prophase: The chromosome makes an exact copy of itself. The chromosome copies are held together at their centers so they form a kind of 'x'.
Metaphase: the nuclei move to either side of the cell and the chromosome 'x's move to the center while the DNA fibers are shortening and thickening and separated evenly to each side of the cell.
Anaphase: The 'x' split up and both the chromosomes and the DNA fibers split to either side of the cell.
Telophase: The cytoplasm pinches at the center of the cell-dividing it in two.

what do you think this is.? Is it amoeba.? or is it just paramecia moving something aroundd.?

This video is about paramecia. Paramecia is a living thing, and in this video you will see the evidence!
Hope you enjoy!(:

Alina sits by me in science. She's a funny girl. She very pretty and I don't know why I'm writing this but whatever it gave me something to do(: and I sit by this very beautiful girl named Hollie!! She's even funnier then Alina!! Haha well this concludes my blog(:

Yes, I think that global warming is happening and i do believe that it is effecting our world! Yes i think we, we as in the humans that live on this planet can stop global warming. If we dont stop global warming then some major things might happen to our planet, some unfixable things! One of the major problems are CARS! They are polluting our air! A solution to this car problem could be riding bikes to get to our destenation. Or we could even carpool. In my opinion, If we made that change and cut down on driving cars that could help the world so much!

My class has been doing a class experiment on how the change of environment affects organisms. This is what we have learned: Liquid 1 was salt water, Vial A had red sand, Vial B had yeast, vial C had polyacrylate also know as "orbies," vial D had radish and vial E had brine shrimp.! So for the liquid one had no changes to their vials. Which would mean none of their organisms were alive. Liquid 2 was sugar water. They had the same observations as liquid 1 except for the radish and brine shrimp. The radish grew sprouts and the brine shrimp moved and hatched!! Then in liquid 3 had the same observations. But only some brine shrimp hatched. And the radish had some great looking sprouts!! What we observed, is that the brine shrimp didn't hatch in it's prefered environment which is salt water.
I think that living organisms appeared non-living because the living organisms need the right environment. If it doesn't then it won't have the things it needs to remain alive!

In my opinion living is if it breaths, if it multiplies, if it moves, if it has cells, has blood and if it metabolizes food then it is a lilting organism.

1, I have two sisters.

so when you have a dead battery it has no energy. Then you charge it and you have chemical energy and when you use it you have electrical energy. and that is what happens with battery energy!!

One cold,wet,muddy day our class went by the chimacum creek and we were going to pull weeeds. It was pretty fun but really cold and some weeds needed more then one person to pull out! There was one root that took four people to pull out of the ground!

Braden, Chelsey And Heidi’s Pamphlet of WATER POLLUTION!!!

What is water pollution?

Water pollution is when water that was once clean is now contaminated.

Which now is neither suitable for drinking nor healthy. It kills fish, plants and animals.

There are some creatures that are tolerant to water pollution, but most are not.

Urban areas have potential to pollute water in many ways. Run off from streets carries oil, rubber and heavy metals into rivers, lakes and streams.

This is the problem!

Trash, car exhaust, oil, fertilizer, pesticides and household cleaners are effecting

Lakes, rivers and streams. They are the main source of pollution, and we are causing our own failure. When we use cars every day we are polluting because of the exhaust. Also when we use cars if they are not properly cared for then they can leak oil witch is a source of pollution. When we litter we are causing pollution.

Consequences of water pollution.

The ocean sustains life on earth its very important. They affect and moderate temperatures and dramatically influence global climate.

The ocean recycles and cleans the air we breathe. Bacteria are produced by pollution, which form a layer of slime on fish and plants. This results in decreased oxygen and increased disease. These are the consequences. Industries release pulp, paper, chemicals and acid rain. Ask yourself if we really want to release this into our world.



What can we do to improve quality after it has been polluted?



People need to be educated about proper ways to dispose of waste.

Showing each other where waste goes and the problem they can create in our watersheds.

People need to work together to help improve water quality. This is an effective way to get the message across. This is also a way to keep our earth clean.

What are some actions that can be taken to prevent water pollution?

Solutions can be finding ways for the urban areas to reduce both its dependents on pollutants. Also trying to get them to reduce the amount of pollutants it produces. One more way is to properly recycle or dispose of pollutants before it contaminates soil, water or air.Us the people can take simple steps to prevent water pollution.They can take care of their vehicles to prevent the oil from the cars from going into rivers, streams, lakes and oceans This is a good way to prevent water pollution.

What are nitrates and how do they get into our water supply?

Nitrates are natural compound present in all ecosystems. It one of the chemicals essential plant life.

All though this is essential to plants too much of it can also be a problem to plants and animals.

It’s also a component of a chemical in manure base fertilizers.Nitrates can enter watercourses and ponds from sources such as areas of high fertilizer life stock feed lots pastures and sewage.

What effects do high nitrate levels have on people?

Excessive nitrate can result in restriction of oxygen to the blood stream.

Infants under the age of 4 months lack the enzyme necessary to correct this condition.

Ground water provides drinking water supply to more then half of the population of the United States.

Sometimes these under ground water supplies can be “polluted” with nitrates can be potentially dangerous to people with conditions.

Public supply wells are usually large wells providing water to hundreds of people within towns and cities. Domestic supply wells usually provide

Water to a single family on their landlord’s property were the well is located. Nitrate concentrations for these two types of wells are commonly quite different.

What is considered to be a safe level for nitrates in drinking water?

The EPA has established a maximum contaminate level of ten m/g/l as nitrogen for nitrate in drinking water.

This is considered a safe level. If this “rule” is not followed there could be extreme consequences.

Fortunately for us we have a very good concentration of this. EPA has formed a specific way of keeping concentrations.

This is a very important job.

What should a person do if there are high levels in their water supply?

Nitrate concentrations in ground water generally are highest in parts of the northeast, mid west and the west coast. Concentrations generally are lowest in parts of the southeast.

This is just general information about were nitrates are highest and highest.

Regional differences are related to differences in soil drainage. Properties and agricultural practices. Nitrate in ground water is highest in areas of well-drained soils

And intensive cultivation of row crops. People could put their water through filters to clean their water and reduce risks.

What can be done to help prevent nitrates from entering our water supply?

By reducing the amount of fertilizer being applied to fields and residential lawns. By doing this we can reduce the potential

for nitrates entering our local watercourses after rainstorms. Tile drainage systems could be placed deeper into the soil. Thereby

Reducing the chance that nitrates will be carried into them.

Watercourses can be fenced to prevent livestock from entering our water supply.

cispus 2009 was great! The food was wonderful, the hikes were alright and the bunk houses were awesome. My favorite thing to do was archery. it was a great experence but it can be dangerous so we were paying atention. when we started learning songs and little dances we had funn and i liked the group i was in so it made things a lot more fun. If we do spimple things like... pick up some garbage,helping up somone that may have fell or somthing like that you can get a bead and there were some people that got at least 20 or even more beads!

1,I have two sisters 2,My favorite color is bright yellow,pink,green. 3,I hate geting my picture takin. 4,I love candy! yummy! 5,I have three dogs. 6,I have one cat. 7,I have a uncle that is the same age as me.
