Cockroach results! -- 06-11-12

2012-06-11T11:25:01-05:00

My team and I did a experiment with cockroaches. We wanted to know if the cockroaches like wet surfaces or dry surfaces. Most of the times the cockroach liked the dry surface. But one time the cockroach went to the wet surface. Overall the cockroach seemed to like the dry surface.

Madagascar hissing cockroaches are brown and oval shaped. Males have large horns used for battles with horned and antlered mammals. They ram one another with their horns and they hiss, winning hussars win more then losing hissers. Hissing is also part of the cockroaches ritual. Mch's Grow 3-4 inches in length. They live on the forest floor and keep it clean.

Snail Experient -- 05-04-12

2012-05-04T11:01:37-05:00

This week my group is doing an experient with snails. We built a house out of black paper, set it on the table and put the snail in the middle of the darkness in the house of just the light from the room. We did this experience to see if the snail likes the light or the darkness. For trail two we are going to put some food in the house and see if the snail wants the food in the darkness or just to go in the light.

Plant Experiment -- 03-22-12

2012-03-22T11:21:34-05:00

The past few weeks we have been doing a plant experiment on rye grass. We watered the rye grass with salt water and sugar water. We used four viles to water the rye grass with salt water, another four viles we watered the rye grass with sugar water, and two more wiles we watered the rye grass with just regular tap water. We thought that the rye grass would grow with the sugar water and we didn't really think that the rye grass would grow that much with salt water, but we thought it would grow at least a little bit. The rye grass didnt grow for a few weeks, then the rye grasses watered with the sugar water started to grow mold and it kept growing more and more, the rye grass watered with the salt water made salt crystals on top of the soil, even the rye grass watered with regular water didnt grow. We researched on what the salt or sugar water effect is on rye grass. For the salt it said that some salt helps the rye grass absorb nutrients but it says that too much salt will kill rye grass. For the Sugar it says that it helps the rye grass grow but it still didn't grow.

Bacteria in our school! -- 02-06-12

2012-02-06T12:27:26-05:00

In the past week we started a bacteria lab. My group took 4 q-tips and wet the ends. We swabbed the toilet seat, the water fountain, the ipad screen and a door handle! Our question was 'What part of our school has the most bacteria?' The water fountain had the most bacteria, there was bacteria all over the water fountain part of the petri dish, it was kinda yellow. The toilet had the 2nd most bacteria, There were yellow splatters on the petri dish. The IPad screen some drops two were kinda big and four were tiny, the size of needle points. The door handle had as much bacteria as the iPad screen and the drops were kinda brown. We might have been inaccurate on the bacteria because there might have been bacteria in the air that got on the q-tips. It's gross to think that bacteria is all over our school!

The difference between Mitosis and Meiosis -- 01-30-12

2012-01-30T12:05:50-05:00

Mitosis slpits apart and becomes two different cells. Meiosis comes together instead of splitting. In the metaphase it creates 4 daughter cells. That is the difference between Mitosis and Meiosis!

Cell Mitosis -- 01-25-12

2012-01-25T11:46:07-05:00

Q1. Chromisomes duplicates themselves. Then both of them move to the opposite cell walls. The cell elongates and its plasma membrane grows inward, then the cell splits. The cell divides and creates two sister cells. Those cells are able to work because the mother cell gives them everything they need to produce and survive.
Q2. Interphase: Is the longest period of the complete cell cycle during which the DNA replicates, the centrioles divide, and the protiens are actively produced.
Prophase: During the first mitotic stage, the nucleolus fades and condenses into chromosomes. Each chromosome comprises two chromatids. Microtubules of a cytoskleton disosemble.
Prometaphase: The nuclear envelope breaks down and there is no longer a reconizable nucleus. Some mitotic spindle fibers elongate from the centrosomes and attach tp kinetochores, protein bundles at the centromere region on the chromosomes where sister chromatids are joined.
Metaphase: The tension applied by spindle fibers aligns chromosomes in one plane at the center of the cell.
Anaphase: Spindle fibers shorten, the kinetochores seperate, and the chromatids are pulled apat and begin moving to the cell poles.

Differences and similarities between plant and animal cells -- 01-03-12

2012-01-03T12:25:56-05:00

In our class we cave been learning about plant and animal cells. We learned what cells are the same and what cells are different. But there are slot of similarities. The cells that are both in animals and plants are nucleus, nucleolus, cytosol, centrosome, cytoskeleton, Golgi, ribosomes, lysosom, peroxisome, secretory vesicles, cell membrane, mitochondrion, vacuole, smooth enapasmic reticulum, rough endoplasmic reticulum. A cell that is only in animals is centrioles. And there are two cells that are only in plants are chloroplast and cell walls! Those are the differences and similarities in plants and animals!

Our polyacrylate experement! -- 11-03-11

2011-11-03T12:23:13-05:00

This week during science we have been doing an experiment. My group is doing an experiment on polyacrylates! We put the polyacrylates in 5 different liquids which was H2O, Hydrogen peroxide, salt water, sugar water, and dirty water. We observed them immediately after we put them in, after 10 minutes, after 24 hours, and after 48 hours. Our question for the experiment was "How does different liquids effect the polyacrylate?" The water made the polyacrylate bigger (645.4 px) and turned lighter colored. The Hydrogen peroxide made the polyacrylate the biggest (670 px) out of all of the other ones. The salt water only made the polyacrylate a few px bigger then the actual size (311.2 px) and it made the water pink. The sugar water made the polyacrylates kind of lumpy, they turned red, and got bigger (634.8). The dirty water made the polyacrylate the bigger (620.3 px). Our inaccuracies were some of the measurements because we couldn't fit some of the polyacralate under the microscope!

Global Warming -- 10-21-11

2011-10-21T12:27:37-05:00

I think that we can help global warming from getting worse! Gases from cars are polluting the world, ways we can stop that from getting worse is by trying to drive less, carpool with other people, and ride bikes places. The way we can save energy is by using enery saving lightbulbs, turning lights off when you leave the room, and wash clothes in cold water. One of the most important reasons global warming is happening it by not recycling, we really need to start recycling! If the temerature keeps rising the ice caps will melt, also the arctic and antartic woud melt! I don't think that many living things would survive that! That's why we need to stop global warming!

Environment -- 10-20-11

2011-10-20T12:26:52-05:00

This week and the last week we were doing environmental experiments on how different materials can change over time! The materials that we used was red sand, yeast, polyachrylate, radish's, and brine shrimp. We put them all into viles which were filled with three different liguids that were filled with salt water, sugar water, and plain water. There was no changes for any of the materials in salt water, they were all nonliving. Even the brine shrimp didn't hatch in the salt water, which is very unusual because that's where brine shimp live. For the sugar water only 2 materials were living which were the radishes and the brine shrimp. The radishes are living because they grew sprouts and the brine shrimp was living because they moved and hatched. In the regular water 2 things were living which were the same things that were living in the sugar water. Some of the living features appeared nonliving because they only can live in certain waters. Some things can't live in salt water, sugar water or regular water. Also seeds hibernate so they don't live or grow sometimes. This is my blog for the environment, thanks for reading!

What is living? -- 10-07-11

2011-10-07T12:26:36-05:00

Living things have to breath, be able to grow, metabolizing food, they can repreduce, if it can move, and if they have cells.

cispus is a very fun camp! Where you do archary, which is shooting boes and arrows. You go on lots of hikes like the pond hike, the spirit lake hike, the angle falls hike and the mount st. helens stairs hike, some of them are prettym long but it is really fun.. beware you might get blisters!!!We get to do skits where you act out parts! We get to sing songs, and do some dances with them! You get to do compatitonsand lots more things to do!!! the girls and the boys get split up in two cabins. Each of us get put in a group and your with them the whole time! So i have lots to say but i dont want to say too much so i think cispus was really fun!!!!

freshwater pollution pamphlet/questions and answers -- 10-27-09

2009-10-27T12:10:15-05:00

Hi we are the team of Brittiney, Sophia, and Shantelle we are going to tell you about fresh water pollution there will be answers to questions you have hope we can answer all the questions you have, enjoy the pamphlet!

What is water pollution?

Water pollution occurs when waste products or other substances change the physical thermal, chemicals or biological characteristics of the water, adversely affecting living species and reducing the water’s beneficial uses.

What are some of the sources of water pollution?

Physical thermal, chemicals or biological characteristics are some sources of water pollution. After the water has becomes polluted we should dispose our toxic substances

Carefully.

What are some consequences of water pollution?

All the garbage from people littering can get washed down to the ocean making animals sick and they can die. Also the ocean can flood the earth by being over flowed. When people dump their garbage in the ocean animals such as fish, birds, and more die or suffer from water pollution from human’s filth like plastic, medal, and Styrofoam.

What can be done to improve the quality of water for becoming polluted?

Solutions involve finding sustainable ways of the urban area are to reduce both its dependence on pollutants and the pollutants it produces and to properly recycle or dispose of pollutants before they contaminate soil, water, or air.

What are some actions that can be taken to help prevent water from becoming polluted?

By reducing fertilizers being applied to fields and was residential lawn, we can reduce the potentials for nitrates entering into local watercourses after rainstorms tile draining sources could be placed deeper into soil there by reducing the chances that nitrates will be carried into them.

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

Nitrates can enter watercourse and ponds from sources such as areas of high fertilizer used, livestock, feedlots, pastures, and sewage treatment areas. Nitrate is applied to fields and lawn’s as a nutrient for plants nitrate is a natural compound present in all ecosystems.

What effect do high nitrates levels have on people?

Some people who drink water containing arsenic in excess of EPA’s standard over many years could experience skin damage and have an increase risk of getting cancer. It causes blue baby syndrome. The water pollution control act of 1972, later known as the clean water act, mandated improvements in sewage treatment technology, to be funded jointly by the federal state and local government.

What is considered to be the safe level of nitrates in drinking water?

19.8% is mostly found in drinking water.

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

We can put purifying tablets into the creeks and pipes so it won’t have any effect on fish. They have to be educated to show kids where the waste should go. It is also community relations.

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

They could purify the water, drink fresh tap water or boil it. Tile drainage systems could be placed deeper into the soil there by reducing the chance that nitrates will be carried into them.
