We found out that cockroaches prefer dry environments rather than wet. we conducted an experiment where we put the cockroach between a dry and wet environment to see which it would choose. it chose dry.
Peace.

KNOW: I know cockroaches are pretty complex insects. They are usually dark brown or brown. Cockroaches have 6 legs. I know they have antenaes on their heads. I think thats all..
WANT TO KNOW: I want to know what other kinds of cockroaches there are other than the madagascar hissing cockroach that we are studying. I want to know if anybody uses these revolting insects as pets. ew. I want to know about the anatomy of cockroaches. I want to know about the reproduction of cockroaches. K. Well. Bye.

Are gross. Very gross. They scare me so bad. And are ugly. Here are some revolting facts: They are only native to Madagascar. Which is why Americans are disgusting for bringing them here...Baby Madagascar cockroaches are called nymphs. Their feet are sticky. They only live 2-3 years. I hate cockroaches.

Odyssey was a memorable experience.. no doubt about that. It wasn't my favorite week of 8th grade, but it was alright. Its better than doing math and history. I liked doing the hikes, they werent that bad. You got to talk to your friends the whole way through. It was fun, i was dissapointed we only got to go to the hot springs once though, even though it smelled like rotten eggs. I look forward to eventually being a counselor in high school.

if you would like to hear what our experment was all about.. then look at my previous blog about our experiment. this blog is JUST for our results. the snail that was in the white box, chose to move to the white paper with the food on it. interesting. not the snail in the black box really surprised me. it went to thr white paper.. weird!! There were no problems in our experiment, it went very smoothly. I claim that the snails are attracted to light. Even after they are living in dark places. This makes me want to know more about the snails eyes.

My group is Hollie M., and Olivia E. Our experiment studies how snails choice in color changes while living in different darknesses. To clarify, we will put snails in an all black box, and an all white box to live in. Then we will see what color they are attracted to when let out. Yeah. That's our idea. #YOLO.

Rye Grass Growth.
Article posted April 17, 2012 at 05:14 PM GMT •
comment (1) • Reads 698

|
The last few weeks Olivia, Hollie and I conducted an experiment on how Rye grass grows when watered with cold water, hot water, sugar water and salt water. Our prediction to start off this experiment was that the hot and cold water would continue growth like normal, maybe the hot would grow a bit slower. We expected the salt to not grow at all. We thought that because the plant is a land plant, not living by the sea where salt water is present, therefore it would die. The sugar we expected for the rye grass to grow more than usual, because of added nutrients for the plant. This experiment was our back up plan, because of problems gathering materials for our algae experiment. Now, for our results. The hot and cold water grasses grew normally. Very consistently. The salt and sugar water, didnt grow. At all, throughout our whole experiment! We concluded that temperature does not affect the growth of the rye grass, and that because of osmic pressure in the plant, and in the sugared water, it stunted the growth of the grass. the salt waters sodium took out the plants nutrients, and the bi carbonate messes with the plants ability to use photsynthesis. Causing the plant to die!

Genetics Reproduction Question:
Article posted February 28, 2012 at 05:54 PM GMT •
comment • Reads 656
|
|
The difference between asexual reproduction and sexual reproduction is found just by the definitions! asexual reproduction is when the offspring comes from one single parent. The genes come from one single parent. When sexual reproduction comes from two parents. as with the genes. They come from both parents. So from sexual reproduction they are more likely to have diverse characteristics because you are pulling genes from two different parents. Asexual only gives you one set of genes rom choose from.

Bacteria in our school!
Article posted February 3, 2012 at 06:27 PM GMT •
comment • Reads 717
|
|
My original question was 'Where In our school does the most bacteria live?' And over the last 3 days we conducted an experiment by swabbing surfaces around our school to put in an incubator at the same temperature as our bodies to see how much bacteria grew. We swabbed 4 surfaces. A basketball, a door handle, the auditorium microphone and the water fountain nozzle. Originally I predicted that the door handle would grow the most bacteria, because so many kids hands touch it everyday. But it was evident that 24 hours after growing, that it was the auditorium mic. I was stunned at how much the mic's bacteria grew compared to everything else. But the more I thought about it, the more it made sense. I mean, your mouth is the dirtiest place in your body, which has been scientifically proven. So the fact that a bunch of kids spit is launched onto it each month and it is never cleaned, it is clear why so much bacteria grew! By the time 48 hours went by there was a colony the size of a quarter that grew. So conclusion of this experiment is that out of the places we swabbed, the microphone in the auditorium carried the most bacteria.

Cell Division
Article posted January 25, 2012 at 05:51 PM GMT •
comment • Reads 820
|
|
Cell Mitosis:
1- 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.
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 seperated 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 I learned about microscopes...

Recently we have been learning about microscopes and how to use them. I learned that our classroom has two kinds of microscopes.. The compound microscopes which have a more powerful zoom, and the digital microscopes that project the image onto the computer.Theres also this thing called the focal plane, which is the plane that is in focus. By adjusting the nob, you can bring the thing closer of farther away to change the plane that you are focusing on. Microscopes help us study objects and organisms that are unable to view from the human eye.

Polyacrylate Conclusion:

comment • Reads 1376
|
|
We tested the diameter of the polyacrylate crystals while they were in dirty water, tap water, hydrogen peroxide, salt water and sugar water. Over the course of immediately, 10 minutes, 24 hrs and 48 hrs. Our question was 'which liquid makes the polyacrylate crystals grow the largest?' After each time interval the hydrogen peroxide caused the orbees (polyacrylate crystals) to grow the biggest! After 24 hrs. the orbees were 653 px in diameter in the hydrogen peroxide. While the closest orbees in diameter in any other liquid totaled 635 px (dirty water). Sometimes when we measured the orbees that were in hydrogen peroxide it wouldn't fit in the petridish for the microscope so the measurements may be a few pixels off. We observed that some of the orbees changed color because of the liquid they were in. For example, the hydrogen peroxide caused the orbees to turn clear, the sugar water made them turn red. I understand now that hydrogen peroxide cause the orbees to grow the most! I wonder what it is IN the hydrogen peroxide that makes them grow.. Mayb e the oxygen? Who knows? Maybe I'll conduct another experiment to find out! I'll keep ya updated!!!!

What is living?
Article posted October 25, 2011 at 06:09 PM GMT •
comment (2) • Reads 1338
|
|
To be considered a living thing, certain traits have to be included in the organism. Such as needing sunlight and nutrients(food), respiration, movement and the ability to reproduce. For example, a hippo is living because it eats, it breathes, it moves, and it has the ability to reproduce babies. Apple juice is not alive because, it doesn't need food.. It is food.. It doesn't breathe, it doesn't move and cannot reproduce other juices..

Environments.
Article posted October 20, 2011 at 06:19 PM GMT •
comment • Reads 1293

|
The environment affects organisms because in order for a organism to live it needs certain accommodations in the environment. For example the radish seeds that we poured salt water in failed to sprout. Although, the seeds that were placed with sugar water and normal H2O caused the seeds to grow! So mainly the environment has to include many traits that the organism can use to live. Some of the living organisms appeared living because of the same thing.. Because their environment doesnt include what they need to live. Today in class my teacher brought up an interesting scenario, why arent seeds sprouting when they are in the package? Its because some living things have to be exposed to certian things in order for them to survive. Seeds need soil, water and sunlight to sprout. To conclude.. Some living organisms appear non living because they havent been exposed to what they need to so that they can appear living.That sounds confusing.. A simpler way to state is that in order to APPEAR living, certain things need to be exposed to the organism. environment failed to include the things needed for the organism to live. Some of the shrimp failed to hatch in the vials because of this. Thanks for reading!

I believe that YES, we can all be doing things to help reduce the warming climate on the earth! For example: we can be choosing vegan and vegetarian meals to eat, using compact flourescent lightbulbs and of course... RECYCLING! Should we be doing something about global warming now? Of course! To be that's a little bit of a rhetorical question to even ask. If the temperature continues to rise.. The ice caps will melt along with the whole arctic and antarctic! And I don't believe that us humans can survive that! Along with the animals that live all around us! Global warming is eventually going to takeover, maybe not in our lifetime, but it will eventually if we don't stop it!

Our worlds oceans are going through tough times right now because of the global tempratures increasing by a third just in the last two years and the lack of oxygen in the water. Dead zones are the leading cause of our wildlife dying in the world. A "dead zone" is a body of water that has an over amount of nutrients from sewage and run-off in the water. The number of dead zones has sky-rocketed from 44 in the year 1995 to over 400! Some of those bodies of water exceeding over 22,000 sqkm!!! The areas of these dead zones include; the Gulf of Mexico, South China Sea, Gulf of Finland, the Black Sea, Adriatic Sea and areas of the Caribbean.This is affecting animals lives in a variety of ways.

What Audrey Learned About Elastic Force
Article posted May 5, 2010 at 09:48 PM GMT •
comment (3) • Reads 1562
|
|
Elastic Force- Elastic force is measured in newtons. It is used by a object with elasticity being stretched and measured by the amount of pressure that is being pulled by the object. The object always wants to go back to it's original shape, so it depends on how thick or thin the object is. (In other words the stretchiness). Our class measured the elastic force of a rubberband. Some of our rubberbands were thicker and harder to pull. Some were very stretchy. The more stretchy the rubberband the less elastic force. Before this, i would have wrote "I don't know" on a test, but now i would get full credit on the question. Thank You Mr.G!! :)

Batteries and Energy Transfers
Article posted April 23, 2010 at 09:40 PM GMT •
comment (1) • Reads 1545
|
|
How energy in a battery transfers from one form to another you are asking? Well here's your answer: The energy changes while charging a battery by having the electrical energy from the circuit in your classroom or house flowing into the battery which is in the battery charger. It then changes into stored chemical energy inside of the battery. Which then when the battery is connected to a light bulb it turns into light/heat energy. Or a motor turns it into mechanical energy. So it flows out the negative side (Flat) and into the variable you are using the battery for. And sometimes it can flow back into the battery using the positive side if, you use a wire to connect it. Which then turns into a circuit.

Audreys Fresh Water Pollution Pamphlet

WATER POLLUTION
First off what is water pollution?? Water Pollution is when careless people dump oil, gas, pesticides, fertilizers, garbage, and other harmful things into the water to cause animals to die and gross drinking water.
WHAT WATER POLLUTION CAN DO
The consequences of water pollution are lower reproduction rates and increased stress on fish, so they are less healthy. Also Bacteria in the water can form. Another consequence is that it decreases oxygen and increases disease. Also some more effects are poisonous drinking water, poisonous food animals. And there are unbalanced river and lake ecosystems that can no longer support full biological diversity. Another is deforestation from acid rain!!! Also there are many other effects but if we told you them all you would eventually get bored.
NITRATES
Nitrates are a primary form of dissolved nitrogen in the natural water. It is a natural compound present in all ecosystems. Nitrates are one of the chemicals essential to plant life, but too much can be a problem for plants, animals, and the environment.
High nitrates can affect people in a lot of ways including, blue baby syndrome. The blue baby syndrome is when an infant or baby in the womb turns blue. They turn blue from drinking high nitrates. Pregnant women and Babies are most affected by high nitrates.
The safe amount of nitrates in drinking water is 10 milligrams per liter.
When there are high nitrates in the water you should, CALL YOUR WATER AGENCY or Do Not Drink It if you have any suspicions about it.
To prevent nitrates from getting into the water you should, reduce the amount of fertilizer being applied to fields. And you could place tile drainage systems deeper into the soil. And you could use a stronger soil for above your septic tank. Also you could REDUCE SEWAGE. Little steps can be a big help to you and animals!
NO MORE WATER POLLUTION!
To prevent water pollution you should, minimize the resource consumption and dispose of waste properly. Also an easy way to prevent it is to RECYCLE. Also, you can keep harmful substances from entering the environment. For example, keep chemicals from going down the drain. And if you finish a soda throw it in the garbage!
To improve water quality you can use high pressure or cold-water treatment. Which is when people spray with fire hoses and then the oil would go down the shore and then you could use mechanical clean up like backhoes and other heavy equipment.
Fun Fact: Non point sources of water pollution are when you don’t know where the pollution is coming from. Point source pollution is when you do know where the pollution is coming from.
Q: Which do oil spills hurt more, animals or the ocean?
A: Oil spills mostly affect marine life rather than the ocean water itself.
Q: How is plastic harmful to the ocean?
A: As far as plastics in the ocean are concerned, they are inert substances. They pollute the world’s waterways in physical instead of chemical ways.
WATER POLLUTION IS BAD!

First I am going to tell you about some volcanoes.The cinder cone volcano is made from loose graiany cinders and almost no lava!! The sheild volcano can reach almost 100 miles across it's base!! WOW!(: Last is the Composite Volcano. This is the type of volcano Mount Saint Helens is!
Now i will tell you about some Lavas. The lower viscosity a volcano has the runnier the lava gets. There are 4 types of lavas we learned about, High Water/Low Silica, High Water/High Silica which is my favorite because it explodes out of the ground!! isnt that cool??? So anyway there is also the Low Water/Low Silica and also there is Low Water/High Silica. I really hope you learned something from my article.
