Pietro's Science Project

Hey guys,
I have all of the materials for my project. The only thing I am worried about is if I have enough examples to show the loss in Vitamin C. I am already boiling and steaming the carrots. Also, do you guys think that Vitamin C tablets or Emergen C are the way to go.My project is not going to take me a very long time so if you have any comments, please email me or talk to me in class. I am trying to get ideas from everyone so if you could talk to me, that would be great.
Thanks

zoe-the effects of acid on metal

My project question was what are the effects of acid on metal. Today is 1 week after i have started my project. The entire project will take two weeks. I have been checking on my project every day and recording my observations. On the first day, I put three of each type of nail(brass, iron, and stainless steel)in 3 cups each. The first row of cups is filled with nothing but air. This is group A. The second row of cups is filled with tap water(to represent average rainwater becuase they have a close pH value), and distilled white vinegar(because it has a close pH value to acid rain). I have had some very intiresting results so far. As time has progressed, each different group of nails put into either water, air, or vinegar, has had different results. I will share the results I just got today, on the 7th day of my experiment.

AIR
(all unchanged)

VINEGAR
Brass- On the 3rd day, the water took on a bluish color and day by day the color has gotten darker and more prominent. However, the nails remain unchanged
Iron- On the 2nd day, a red line formed around the edge of the vinegar at the top. Over time, the line has gotten darker and more red. The nails, which when I bought them were a metallic color got to be completely black by the 4th day. There are also many black flakes that have fallen off the nail and have gathered at the bottom.
Stainless Steel- There is a red line much like that on the iron, but more orange in color. The nails, however, remain unchanged.

WATER
Brass- On the 5th day, some small, white precipitates formed, but they are now gone and the nails look unchanged.
Iron- On the 2nd day, the process of corrosion started, but today, the nails are completly coated in a light orange rust. The water has also taken on this color, because the rust color from the corrosion leached into it. The coat of corrosion looks very thick, almost like a fur coat.
Stainless Steel- On the 3rd day, corrosion patches started to form and today the patches are very big and thick. The color, like with the iron, has leached off into the water. There is now a vein like pattern that is going along the bottom of the cup. The color is more re than with the iron.

Abby Part #1

Hi! Thursday the 18th i made my clay, aka "Play-Doh." I made four different kinds, a really easy and sticky one, an oatmeal one, a really good and regular one and a cinnamon one. Here are the recipies:

Easy and Sticky
2 cups flour
1 cup water
Then knead well...

Oatmeal
1cup flour
1 cup water
2 cups oatmeal

Regular and good
1 cup flour
1 cup water
2 teaspoons cream of tartar
1 teaspoon olive oil
1/4 cup salt
This one has to be stirred over medium heat then kneaded until the foodcoloring (if you put it in) is well mixed in... this one was thought by many to be real store bought play-doh. (this one has the picture of a pot... this is what it looks like before it is kneaded... don't be fooled its not burned!)



You can add food coloring or colored drink mix to any of these and it will change that color!

And the last... (this one can't have food coloring...)

Cinnamon
1 1/2 cup cinnamon
1 cup applesauce
1/3 cup glue

Next i want to try to find out which one is the most sqeeziest... so what im going to do it take two 6 by 6 boards and put the play-doh between them. Then im going to put a weight on them and let it sit there for one hour and which ever one is the thinnest after the hour is the most squeeziest.


This is my sister, my brother and me kneeding the really really really sticky and simple one... my half of the class knows how sticky it is!

This is a really fun project so far and i sugest whoever reads this make some of these recipies or go on to google or yahoo and type in Playdough recipies!

Kayleigh - Part 1

For my project I am testing to see the distinction in burning different fabrics. I am going to burn a total of 11 different fabrics in which I have cut out 4 2x2 squares. I definitely know what type some of the fabrics are, but there are others which I am not so certain. I am using a fabric burn chart found in my research to do 2 things: 1 find out what type of fabric it is and 2 to see how accurate the chart is compared to what actually happens. I plan on burning 2 of the 4 individual fabric squares. The first time is a trial run to get an idea of what happens. The second time will be to write down observations, take pictures, and see if there was a distinct difference between the same burning fabrics.

TJ can't Get the Glue to Stay

For my hurricane project, I have to build 9-10 houses in total. Each house has 74 sticks. Which means that 740 sticks... There's all kinds of convoluted math in this but it all ends up with GLUE! Glue, glue, a little wood, AND MORE GLUE!!!!!! I currently have used 5+ packs of 96 sticks, which is somewhere around 510 sticks. And I'm NOT EVEN NEAR DONE!!! I have, plus joints and assembly, 3-4 Houses to build. I only have one fully constructed. There's a lot of work to be done still, and not much time. Here, see what I mean.

THIS is why you don't build a lot of one side.My Workspace

See you with results soon!

Dani's Roller Coaster Project: Part 2

After taking a little over half an hour to set up the track, the testing began. I was going to change the angle of the lift hill from 45, to 60, and then to 75 degrees. The first few tests with the 45 degree angle did not look good. It kept falling off the track at the loop. The same goes for the 75 degree angle tests. They nearly mirrored the 45 degree tests. However, all but one of the sixty degree tests came out perfect. It just gave me an enthusiastic feeling to see that little marble go through that big loop, not once, but twice. Doing all of this only took me about ten minutes. If I could do the all again, I would (without the almost falling off the stool part, of course)!

Put this picture in the URL to see the 75 degree angle that mimicked the results of the 45 degree angle test.

Dani's Roller Coaster Project: Part 1

I started setting up the roller coaster at around noon today, February 15. I first took the pipe insulation to cut it in half. On one side of the insulation, there was a perforation, making the cutting easier for me. I then started to put up the track. I used a lamp, a chair, and a little rocking horse as supports for the track. Putting it up turned out to be more dangerous than expected. I had to stand on a stool so I could reach the top of the lamp, but then, I almost fell flat on my face. Luckily, the stool tipped forward and backward, and then settled. After that, setting up went just as planned.
