Plant ExperimentTtTtTt -- 05-09-12

2012-05-09T13:26:09-05:00

My team tried to get a clock to run off of potatoes(or any kind of tuber). we couldn't get the clock to work so we went on and tried to get a small light to light. we also had a volt meter, and we measured how much power we got. potatoes weren't enough to power much, so we tried yams. we successfully got 4 volts out of the yams but we still couldn't get the light to light. we tried a 1 1/2 volt battery and it light. i don't know why.

What i know and want to know about snails -- 05-09-12

2012-05-09T13:19:13-05:00

I know snails are small, cannot hear, and rely on there smell for food. I want to know if snails can see and if they can see colors.

Shnailz Experiment -- 05-09-12

2012-05-09T13:16:56-05:00

My team is going to see what color a snail goes to if it has the choice. we will use four colors, orange, green, blue, and yellow.

Snail Conclusionnnnnnnnnnnnn -- 05-09-12

2012-05-09T13:10:40-05:00

my team did an experiment on which color a snail would go to if they had the choice. so we set up a box with orange, green, blue, and yellow colored paper. we covered the middle with white out in a circle, and we put the snail in the circle to see which color the snail went to. he/she didn't go to orange, went to blue twice, green once, and yellow twice. Snails.

Genetics Formative Assesment Question, Chet -- 03-01-12

2012-03-01T14:03:14-05:00

They are more likley to have more divers offspring because the offspring gets 23 cells from the dad and 23 from the mom, and nature shuffles those genes and places them randomly. asexual reproduction, the cells separate and are copies of the original cells.

Bacteria Lab Conclusion -- 02-06-12

2012-02-06T13:57:53-05:00

The sink knob had the most bacteria on it. my question was what area of the school had the most bacteria on or in the certain areas. the second most was the lunch tables, which had a big white dot. the gym floor had a little strip of bacteria. and the Trip Lever (Flusher) on the toilet had the least.

Motosis and Moisis -- 01-31-12

2012-01-31T14:29:48-05:00

Mitosis refers to a division of cells. Meiosis on the other hand is to the division of gametes. So it goes diploid to haploid. The difference between Mitosis and Meiosis is that Meiosis is a sexual reproduction of cells and Mitosis is not.
Meiosis is a unique type of cell that mak gametes with not as many chromosomes. The opposita process would be syngamy or fertalization, a very different organism that has unique difrent ither parent is made. The sygote divides and grown to form an embryo which turns into a young organism.
Mitosis is where chromosomes are copied and split. It starts with prophase. Prophase is when the DNA duplicates. They became exactly the same like a copy in. eres metophase which is when the DNA duplicates and face eachother. On the opposite sides. Anaphase is next and is when the daughter chromosomes move away from eachother to opposite sides of the cell. Last is telephase and thats where all cells split to form nuclei.

Cell mitosis -- 01-26-12

2012-01-26T14:27:18-05:00

Q1. Chromisomes duplicates each other. Then both of them move to the opposite cell walls. The cell expands and its plasma membrane grows inward, then the cell splits. The cell divides and creates two sister cells. Those cells are able to work becase the mother cell gives them everything they need to produce and survive.
Q2. Interphase: Is the longest perod of the complte 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

Prometaphase: The nucler envelope breaks down and there is no longer a nucleus that you can recognize. Some mitotc spindle fibers elongate from the centrosomes and attach tp kinetochores, protein bunches at the centromer region on the chromosoms where sister chromatids are joined.
Metphase: 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.

the paramicia, and amobia are single celled, but the elodia has multiple cells. The elodia is independant and doesnt need the paramicia, or amobia to live on its own, but the paramicia and amobia needs other cells to survive. so you can tell because they need oher cells to survive.

microscopes -- 01-03-12

2012-01-03T13:56:27-05:00

the microscopes have 3 focuses. 10 40 and 100 times. for 100 times you have to use the fine focues to see.

Polyacrolyte Crysal Experiment! -- 11-08-11

2011-11-08T14:16:31-05:00

I took 5 energy drinks Best Shot, 5 Hour Energy, Amp, Red bull, and Monster MX3 Super concentrate. We put 5 Polyacrolyte Crystal's in each vile. we had 1 vile for each energy drink. The amp got the biggest polyacrolyte crystals. on day 1 amp got 28.4 pixels, on the second day it had grown to 363.225 pixels, on day three they shrank down to 354.9. the second runner up was the monster. they had 28.4 on day one, 356.875, and day three hey had a, 545.5. the third was red bull. the first day was 28.4, the second day they reached 285.2, and day three was 276.6. The fourth was best shot, day one was 28.4, the second day was 265.625, and day three was 216.1. the last was five hour energy with a day one of 28.4, day two was 251.25, and day three was a 102.75 they all turned the specific color of the drink, the amp and monster and mp turned green, the five hour energy and best shot turned red and pink, and the red bull had different colors, but one of the red bulls had bubbles form inside it which prevented growth, that took down the average of the red bull and that's probably why it was three, most of the other red bulls were as big as the amps.

Enviroment! -- 10-25-11

2011-10-25T14:08:42-05:00

The Enviroment can effect things by heat, cold, the amount of moisture. Different things need different stuff for it to live, for example, Plants need Carbon dioxide, and people need oxygen.
if its really cold than a spider cant be out in the open or it will freeze. like the Eggs hatched in the sugar water but in no salt water. The Orb things obsorbed the water and got bigger.
The liquid we had was tap water. The yeast wasn't showing any signs of life but you could just barley see the bubbles of it, sadly the bubbles stopped breathing once a person shook the canister for ten minutes. the radishes sprouted out roots into the cotton balls.

Global Warming -- 10-03-11

2011-10-03T14:24:05-05:00

Can Humans Help Global Warming?

Yes, i think so, if we would recycle more and drive more nature friendly cars, our enviroment will last a lot longer. I think the plastic is bad for our enviroment and we need to recycle.

elastic force relates to gravity and when you pull it back it will have ressitance and want to go back to its normal form every time you pull it back the force will be doubled

batteries and there history -- 04-26-10

2010-04-26T12:02:50-05:00

The first battery was made by Alexandro Volta he created his first one in the late 1800's.
a man named Davy created a more modern battery that was much more powerful. but it was impractical for everyday use because it was about the size of a classroom so it was way to big for anyone to pull along with them. some scientist's don't think Volta was the first one to make a battery because they found 3000 year old battery's that jewelers used to make gold trims of jewelery and other thing like that. hope you learned about batteries history

Energy and batteries #1 -- 04-23-10

2010-04-23T12:20:55-05:00

we learned about batteries and energy, we had some experiments about testing how long batteries would last with flash lights. we charged them for 30 seconds 60 seconds 120 seconds and 240 seconds. after the thirty seconds they lasted 12 seconds, with the 60 sec it lasted 37 sec for the 120 it lasted 1:20 sec and the 240 it lasted 3:07 sec

What is freshwater pollution?

Water pollution occurs when waste?
Products or other substances change physical,
Thermal, chemical, or biological characteristics of the water. Pollution is Adversely affecting living species and reducing the waters beneficial uses.

What are some sources of water pollution?

Some sources of water pollution are trash, waste, landfills, oil spills, and chemicals.
Those things make water polluted and could get into your drinking water and make you very sick. Oil spills could hurt you a lot and it kills tons of animals. Like the Exxon Valdez
Oil spill. It killed tons of animals and if the might not have cleaned it, you could of drank the oil in your water.

What are some consequences of water pollution?

If it gets into our drinking water you and your pets could get sick.
You could get sewage into your water and body. Imagine drinking sewage it could make you and your pets very sick. Or if oil got in your water supply that would be very bad.

How do you improve the quality of the water after it has been polluted?

You can purify the water that is one of the most vital ways of cleaning pollution.
We can throw a way are trash and stop dumping in the water and evenchley the water will be cleaner.

What can be done to improve the quality of the water?

Top pouring are waste and trash in to the water or make big net with really small holes so the water can go through and the oil, dirt, and other things that could pollute the water.

What are nitrates and how do they get into our water supply?
Nitrates are natural and created by plant-based chemicals
And fertilizers. To many nitrates can make you sick. So you shod not drink water with to many nitrates. If someone in your house gets sick from water in your house you should check it.
