ODYSSEY!!!! -- 05-29-12

2012-05-29T11:03:29-05:00

Odyssey was actually a lot better then i thought it was gonna be! it was a really great experience for me. I was really happy that our 8th grade class and all the other 8th grade classes get to experience it.
My favorite part of Odyssey was probably just getting to hang out with all of my friends for a full week! I think if i could change 1 thing about Odyssey it would have to be the food. I am very grateful to the cook, but i really wish that the food could of been just a little better.
I hope everybody else had as much fun at Odyssey as i did:)

snail experiments conclusion!!! -- 05-10-12

2012-05-10T11:13:41-05:00

for our snail experiment we wanted to know if snails prefer to be in light or dark. i thought the snail was gonna be more attracted to the dark because it would be more hidden and i was some what right!
we maid a snail hotel (hahah) out of black construction paper and put a piece of paper with peanut butter on it inside of the snail hotel (which is dark) and outside of the 'hotel' which is light. at first the snail went to the peanut butter in the light then after a little while the snail went to the peanut butter in the dark and stayed there.
i believe my claim was right because the snail, even though it wasn't there the whole time, stayed in the dark after it went in there.

8th grade plant experiment!!! -- 04-17-12

2012-04-17T11:28:22-05:00

my group and i did an experiment on rye grass. we wanted to know how different amounts of salt and sugar Water would affect the rye grasses growth. well, all it did was mold... even the plant without sugar or salt molded.
we started the project by taking 10 viles (5 for suger water and 5 for salt water) 1 vile out of each set of 5 had just plain water in it. well, none of our plants grew... though we researched and think we know the reason why!:)
so for the salt water, we believe that because the salt water Weekend the plant and caused waterstress to the rye grass even though it had plenty of water. We think the rye grass died that sat in the sugar water because the plant was over watered and couldn't absorbe it due to the presence of sugar unbalancing the plants ability to absorb moisture.

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.

polyacrylate project conclusion! -- 11-04-11

2011-11-04T12:16:15-05:00

my team an i did a class project on polyacrylate. we put three polyacrylate in each vile. we had 5 viles tottal. vile A: h20 Vile B: hydrogen peroxide Vile C salt H20 Vile D: sugar H20 nd Vile F: dirty H20. we found that the polyacrylate grew the biggest in the hydrogen peroxide. it also got pretty big in the sugar H20, dirty H20 and the reg. H20. it didnt grow very much in the salt water though? something that suprised me was that the polycrylate lost almost all thier color except for just a little pink in some. i understand that the water viles grew the biggest but i dont understand quite yet why the hydrogen peroxide made the polyacrylite grew the biggest.

Environment affects organisms??! -- 10-20-11

2011-10-20T12:26:11-05:00

You wouldn't think that an environment would affect the organisms living there. Well, It does. Sometimes you wouldn't even know an organism was living until it is put in a certain environment. An example of this is Brine Shrimp.
Our 8th grade science class did an experiment using different living and non-living things. One of the living organisms we used were brine shrimp. The class used three different liquids. Sugar water, salt water, and reg. Water. The brine shrimp didn't look living at all when they were first put in the three waters, but after 24 hours we found out they had hatched in two liquids. Salt water and Sugar water. This was weird because they should of hatched in the salt water.
Sometimes living organisms appear non living because it doesn't have the things it needs to hatch:)

What is living? -- 10-13-11

2011-10-13T12:26:59-05:00

In my opinion, living is anything that breathes, has cells, has a reproductive system, consumes food, and has origins (heart, brain) .

changing energy from one form to another -- 04-23-10

2010-04-23T10:33:10-05:00

you can change energy from one form to another by charging and reusing a battery! when you use a battery, the battery has electrical energy. when the battery runs out of energy you can recharge it if it is rechargeable. when you recharge a batteries energy turns into chemicle energy. then when you use the battery again it turns back into electricle energy

valcanoes and lava -- 11-05-09

2009-11-05T19:01:46-05:00

andnbsp;

Iandnbsp;am going to tell you about some different types of valcanoes. Composite valcanoes have steep sides. They also have a layer of lava that is mixed with sand. The lava and sand is what builds the valcano.

andnbsp; A sheild valcano is hundreds of miles wide and ten thousands of miles high. Sheild valcanoes consist almost entirely of frozen lava, and have low slopes. this valcano also has large craterson the summit.

andnbsp; The gint caldera is the largest of the valcanoes. This valcano can be as big as the yellow stone park! they can blow ash out thousands of miles away!

andnbsp;The last valcano is called a cindercone. It is made of loose gravel, sand and has barely any lava. This valcano is miles wide and thousands of feet high! When this valcano eurups it shoots out cinders and that is how it got its name!

andnbsp;andnbsp; and those are most of the valcanoes and their lavas

My cispus expierience! -- 11-05-09

2009-11-05T00:00:00-05:00

My cispus experience was GREAT. My favorite part of cispus was probably the campfire when everyone put on a skit. Another activity that i liked at Cispus was the angel falls hike. i liked it because at the end of the hike we all got to hang out on a bunch of logs and that was a lot of fun!andnbsp;andnbsp; those are some reasons why i thought i had a good Cispus experience!

Water Pollution Pamphlet -- 11-02-09

Water Pollution Pamphlet
By Hadlei, Jacob, and Alina

In this pamphlet you will be reading about freshwater pollution and nitrates.
Plus you will also be reading about some main sources of freshwater pollution. You will also be reading about point and non-point sources of pollution. Have fun reading this pamphlet.

What is freshwater pollution?
Freshwater pollution occurs when waste products or other substances change the physical, thermal, chemical or biological characteristics of the water. Affecting living species and reducing the water’s beneficial uses. A river is polluted when a substance, which degrades the water quality, enters the water and alters its natural functions. Some sources of water pollution are farmers using fertilizer and it getting into groundwater and it getting into water. Also sewers sometimes run off into rivers, creeks, and/or lakes.

What are nitrates and are they bad?
A nitrate is natural compound in all ecosystems. It is one of the chemicals essential to plant life. Too much can be a problem for plants and animals. It is also a component of chemicals and manure-based fertilizers. So nitrates can be bad if there are too much of them in your drinking water.

How can WE prevent water pollution?
We can prevent water pollution by picking up after ourselves. For instance pick up trash on the side of the road when we go on walks. Or maybe recycling whenever we can. Reduce, reuse, and recycle as much as possible. Use chemical at least 200 feet away from main water sources. Those are some of the ways we can prevent water pollution.

How do Nitrates get in the water?
Nitrates can sometimes enter water sources in areas of high fertilizer use. When too much nitrates get into water it can be harmful to plants and animals. Other ways that nitrates can get into water if there are high sewage use and feedlots near by. Those are some ways that nitrates can get into water.
What is point and non-point sources of pollution?
A point source is a specific source of pollution that can be identified. A non-point source is a wildly spread source of pollution that cant be tied to a specific point of origin. The difference between the two is that a point source CAN be identified. A non-point source CAN’T be identified easily. Those are point and non-point sources of pollution.

In this pamphlet you read about fresh water pollution. You also read about nitrates and how they affect us and plant life and animals. Plus you read about point and non-point sources of pollution. I hope you enjoyed reading this pamphlet of ours.

Thanks from,
Hadlei, Jacob and Alina
