Cells

In science, we are learning about cells. Cells are considered the basic units of life. To start, each cell has a cell membrane. The cell membrane protects what is inside. In plants and algae, the cells have a cell wall. The cell wall gives the cell membrane support and strength. After that, there's everything inside. The "computer" of the cell is all in the nucleus. The DNA is in the nucleus. The DNA contains the information needed to make the cells proteins. There might also be a nucleolus inside the nucleus. Next, there's the ribosomes. The ribosomes are very small building blocks of cells. These ribosomes carry messages to the endoplasmic reticulum. The endoplasmic reticulum (ER) is known as the delivery system of the cell. The ER transports protiens (that come from ribosomes) somewhere else later, after storage. The mitochondria of a cell is known as the energy system of a cell. Did you know the reason you breathe is so the mitochondria has the oxygen it needs? Plants and algae have chloroplast which is responsibe for converting energy. Lastly, lysosomes contain enzymes.

Roller coasters

Bloggers,

I realize this is a bit late, but here are some really cool site to go along with the post named "Rollar Coasters" (with an A [=) Please look at these sites, they are really cool!

Great one to start off learning the physics and just messing around to see what you can get out of observations.

Great one to see it action and have a detailed explanation as you go along. Mix and match around and see what you get out of it with an explanation!

Great website for the final step... SAFETY! Mix around and see how well your audience likes it
-- safety wise!

Sprinklers Flood a Police Station

There are sprinklers in some of your houses. What if they cracked? Then what? A leak or nothing might be expected, right? But, what if the results were much more worse... Like a flooded police station?!?!

In the South Brunswick Police Station, cracked sprinkler heads created turmoil and damage on the first and second floors. The damages made cost about $158,327. There was also lots of damage done to the equipment. ”The fire sprinkler heads burst and it caused substantial damage to the lower floors at the Police Department,” claimed Ron Schmalz. “Once our dispatchers saw the heads leaking they called in Public Works, but those sprinklers throw out a lot of water so by the time they got it turned off there was substantial damage.” Mr. Schmalz also mentioned that the police were in the middle of some work while this had happened, but they evacuated soon enough. Mr. Schmalz also said that repairs are almost done. Although, out of all the damages, the worst is probably the carpet! $74,918 will be needed to replace it! A computer, a projector with a lamp and new ceiling tiles also need to be replaced.

Rollar Coasters

So here's the deal, bloggers. We're building these amazing roller coasters that use physics to operate. But the thing is, they are made out of paper products and are only about 4 feet tall. Some ride, huh? Not really! Our "company" needs to figure out how to make a roller coaster that has at least three hills and one other characteristic of a roller coaster. At the end of designing, we need to drop a marble into the entrance and see if it will go through the whole thing with out stopping.

Easy? Not at all. We have to buy all our supplies - with money that is earned hardly. Since this is MY blog, I will be honest. Ten O-Dollars for one toilet paper tube? Crazy right? That's okay. Be polite with Treasure, the Shopkeeper, and you'll be rewarded! My point is, spend your money wisely and your roller coaster is perfect. Less can be more very often.

Other than the money factor, we have a PHYSICS factor! Some questions we have to ask ourselves some questions. How will our roller coaster function? What should our design be so the marble will gain lots of energy to be able to easily overcome the hills? How will we get support for cheap? $5 for lots of tooth picks or $1 for a straw? What should we use?

In the end, we still are working on it. I hope by tomorrow it will all fall into place. We have come across some problems, but we have easily fixed them. Maybe next week I will post a detailed diagram of our roller coaster and how it works.

But for now,
Adios!

Iraq Moves Towards Democracy

Finally, the moment has come. Iraq is making swift movements toward Democracy. Although only 51% of registered voters showed up to vote, everything ran as smooth as ice. There was no violence or riots. There was lots of precaution taken to avoid any violence and riots. This is the first time that voting has been set up the same way it is set up here in America. Voting centers were set up based on addresses and location. Iraq is divided into 18 provinces. Each one is led by provincial councils. Provincial Councils monitor the budget and infrastructure projects. In the election that took place, over a thousand people ran for a position that was only meant for 440 people! President Obama had a very positive outlook on the whole thing. He had said "I think that you have a sense now that the Iraqis just had a very significant election with no significant violence that we are in a position to start putting more responsibility on the Iraqis and that's good news not only for the troops on the ground but for the families who are carrying an enormous burden." I, myself, am very proud with the Iraqis. They are doing a fantastic job with coping with us. Of course it will take a while to count up all those votes, but until then, GREAT GOING IRAQ!
