Cern and Cells

Hello everyone,

Yesterday May 17th we learned about cells and CERN. Cells are the basic unit(structure,function) of every living thing. Ms.D asked us how do we know if we are alive? Many of us had different answers but most of us said by movement. Ms.D said that we know if we are alive by movement, respiration, reproduction etc. There are 6 kingdoms Animalia, Plantae, Fungi, Protist, Monera, and Archaebacteria. Animalia is the animal kingdom. Plantae have cell walls that are used to protect the plant, and chloroplast which makes the plant green. Fungi is where the mushrooms and other fungus go. This kingdom decomposes waste my teacher from Ecuador told me they kind of recycle a big part in nature.

Monera is where bacteria fall into. They told me that most bacteria is actually helpful to your body.In my other school they taught me that archaebacteria was part of the monera kingdom but Ms.D said that it was separate kingdoms. Archaebacteria is bacteria that live is extreme environments.

Large Hadron Collider

this is what the hadron collider could affect us.The Large Hadron Collider at CERN near Geneva, Switzerland will open new views on the deepest secrets of the universe, stretching the imagination with newly discovered forms of matter, forces of nature, and dimensions of space which it is pretty cool and we could advance greatly in technology. Then we saw a couple of videos about the hadron collider and a presentation. We also saw a funny video of some people that work there and made a rap song. We are going to Geneva, Switzerland mostly because of the Hadron Collider. The Large Hadron Collider, or LHC, is a facility at the European Center for Nuclear Research (CERN) on the French-Swiss border. It is designed to take particles at high energies and smash them together, to see what results are obtained. This Machine is huge and amazing, also with this machine we could do black holes which they are awesome.

Taking Down Simple Machines On Thursday 12th May

Hello to everyone!

Thursday was a very busy day for all of the seventh graders in science class! We immediately began working. Ms.D had already written on the white board what we had to do during that class, we had to begin by giving in our notes that we should have done for homework, if someone wasn't there, they are due tomorrow, and you are supposed to read pages 6-13 in your Cells science book, and take as many notes as possible. We did not have time to review all the information, so instead we immediately continued working on our compound machines! They were supposed to be due last time, but since the teams had not been able to complete everything, we were given 15 minutes to finish our compound machines and get the working and set! So each team got to work:
The Cookie Monsters (Karin, Jakub, Me, Courtney, Maria Chiara, and David), had to work a bit more on getting the chain that brings the balls on top working and to not let it get stuck.
The Evil Elves (Davide, Ghazaleh, Emilija, Tamara, Ben, and Nathan) instead had to finish building the compound machine itself!
These are the two groups at work!
First, the cookie monsters trying to get the chain to work!

Second, the Evil Elves testing if their ramp works, and fixing it!

When the 15 minutes were done, both teams were pretty satisfied with their work and the team effort that had gone into building these machines! So the both teams backed away from their work, and each team picked ONE team member to turn the chain during the test, the Evil Elves picked Davide, while the Cookie Monsters picked Karin!

Here are the Evil Elves at their final test!

Here are the Cookie Monsters at their final test!

So the results were...... EVIL ELVES...... 3 out of 4 ramps complete!!!! (APPLAUD)!

and the COOKIE MONSTERS...... 4 out of 4 ramps complete!!!! (APPLAUD)!

After the very exiting hour, Ms.D gave us a five minute break to rest and relax...because after that, one of the most exiting parts of the compound machine came....to take it DOWN!!!

The whole class got busy to work, and each team had a different method, the Evil Elves took down everything and then sorted everything into bags, while the Cookie Monsters sorted the things while taking them down. The class worked hard for the rest of the block, and the compound machines were almost over by the time the class was over, so we stayed in at break for a little longer just to be able to finish the compound machine and be able to close the whole chapter. The cookie monsters soon after finished, and they packed up and left. The Evil Elves stayed in a bit more, and little after also finished, concluding this year's...SIMPLE MACHINES!

We were also given a short homework: you have to high-lilght all the important facts that you think are relevant on the sheet that Ms.D gave us, called Building Blocks Of Life- The Parts Of A Cell, and put a * next to any word or phrase we did not understand or would like Ms.D to explain!

Here are two websites in case you want to learn something more about cells and their structure!

Cells!
Cells!

Chiara's Scribe Post 4th Quoter

Tuesday 10th Science class

Hello everybody, Tuesday class was our last class to build the compound machine, I am writing  for the team of the Cookie monster!! The compound machine it's a big machine made of simple machine. There are seven simple machine.

Those are:

Incline plane

Screw

wheel and axle

pulleys

wedges

Levers

Gears

In this big machine there ere all of the simple machines or almost all of them, because there are no wedges. Wedges break things a part, and this machine there is no kind of thing happening. As you can see the roller is a inclined plane. The little wheels on the top of the inclined plane is a wheel and axle. At the top of the machine 

there one screws build. In this machine there are also third class lever. But any thing is wouldn't work with out a pulley, infact the main thing wouldn't move, because the 

pulley brings the ball up and it make it do every think again. In the middle of the class parents 

came to see our machine. After in class came the 2nd, 3rd and 4th grade to see our machine. 

When they came the room was really loud and every body was yelling: cool!!! 

At some point Ms.D. told as to clean up all the pieces were left  on the floor,  and she ask as to test our machine before we would leave the room The Cookie Monster  machine worked well, because all four track worked; however, the Evil Elf machine 

only two track of four worked well. 

DO NOT FORGET to go and look at other post, ther is also interesting facts about simple machines!!!!

Here some links that can help:

Wheeal and axel

Pulley

Lever

Inclined plane

Moodle

 The home work is to email Ms.D and to take notes. Make your blog comment, Which is due Friday the 20th, but that day we are in Swizerland.

Real life example: The  roller coster, refer to the ramp of the machine

Next scribe is..........Vale!!!!!

Tuesday, Thursday, and Friday Science class

Science Class

(This is the Cookie munster and the Evil Elves)

Hello everyone! I am going to talk about Tuesday, Thursday, and Friday science class. The Evil Elves were a little bit behind the Cookie Monsters, but me and Davide came at lunch and also after school, and now we (The Evil Elves) are at the same position as the Cookie Monsters, because of me and Davide’s extra work. The Evil Elves are doing an awesome job on our compound machine!!! By the way, it is as tall as Davide(sorry Davide)!! And I think everyone in our group is doing a very good job and they are working as hard as they can.

On Tuesday's class we started to talk about the blog and comments, since some people did more than they had to on their comment, and Ms.D was also said who should do the scribe post for Tuesday, Thursday, and Friday - and it was me (Ghazaleh) and David Mamic. The Evil Elves (me, Tamara, Emilija, Ben, Eric, Nathan and Davide) were still Working on the gears, but that was just for a little bit of the class and then we started to work on the compound machine, but the Cookie Monsters started to work on their compound machine from the beggining of the class, so they had more time than we did...

On Thursday's class we started to talk about: when are we going to finish our compound machine and also talking about an email that we are spoussed to do when we are going to finish our compound machine. Ms.D also talked about the comments that we were spoussed to do to 8th or 7th grade. After we finished talking about the comments and the email and when we are supossed to finish our compound machine, then we started to build our compound machine. I made some mistake that was not good for our group, but Emilija came and helped me to correct my mistake. We were also missing a person of our group which was Tamara.
On Friday's class we started to talk about the comments and because some people did more than they had to on comment, so Ms.d asked them which one of the comments they wanted her to grade. After that she reminded me and David to do our Scribe Post for Tuesday May.10th.2011. After that Ms.D talked about the blog stuff then we again started to work on our compound machine.

This are all the things that we did last week science class. I hope you enjoyed while you were reading.

This are some links that you can learn more a bout the compound machine:

Last Week for Simple Machines

This week was the last week that we got to work on our simple machines before we had to start working on the large compound machine. The Cookie Monsters are ahead of the Evil Elves for now but who knows what might happen. The Cookie Monsters now have enough credits but have to finish the whole gears section before they can start the compound machine.

These are some of the simple machines we got to build so far:

This week, as you see, we had the last chance to finish our small simple machines and collect enough credits to move on to the compound machine. The Evil Elves were working on levers but now went on to gears, and The Cookie monsters are currently working on gears.

Ms. D also told us that once we are done with our blog post that we can write our reflection post right away. Here are some things that you should include in your reflection post:

*How do you feel you have improved as a blogger over the past year or two?

*How do you feel blogs contribute to learning for a class in school?
*What else do you think a blog could be used for?
*How has blogging helped your overall writing?
*How has blogging helped your commenting to others about their writing?
*What is the most important thing you have learned from blogging?
**** Don't forget to label your post with your name, Reflection Post, 4th Quarter!****

For our other homework assignments i put a link to moodle at the bottom of my post.. I also found a bunch of videos from eureka. There is a video for the screw and the wheel, the inclined plane, the lever, the pulley.

The Inclined Plane -http://www.youtube.com/watch?v=pG_kT565-XQ&feature=BFa&list=PL356D58984641EDC6&index=1

The Lever -

http://www.youtube.com/watch?v=wV1pYkTtsxg&feature=BFa&list=PL356D58984641EDC6&index=2

The Screw and Wheel - http://www.youtube.com/watch?v=C-UXry7OiXM&feature=BFa&list=PL356D58984641EDC6&index=4

The Pulley -

http://www.youtube.com/watch?v=TlPWy7qW7oM&feature=BFa&list=PL356D58984641EDC6&index=5

These videos will explain all types of simple machines. There are actually seven types of simple machines, they are the screw, pulley, inclined plane, wheel and axle, lever, gear, and wedges.

Although this week we did not do much in class except for build with knex, we got to have a lot of fun with it. And even though they are called simple machines they can become very complex. like this model of a ferris wheel built from knex:

Even though this ferris wheel looks very complicated it is actually made of two or more simple machines. From just looking at the picture i can already spot one... a wheel and axle that go through the middle of the ferris wheel. So now you know that no matter how complicated a machine may look, it is always made of one or more of the seven simple machines.

The next scribe is... Drum roll... David!!!!

Tuesday, Thursday, and Friday's science class

Tuesday's class

We began Tuesday's science class with a nice discussion about the blog, but we were first introduced to a new student in our class Eric. After this, we talked about the blog, in particular, about when the comments and blog posts are due. Ms. D gave us a rubric on the comments and post, so that we can write the comments based on the rubric. This was a very quick discussion, so we very quickly started building with K’nex. The rest of the class we built, and finished the rest of other K’nex projects, the one’s that we didn’t get to finish last class. We all had a great time! 5 minutes before we were let out Ms. D told us to clean up, and she told us “feet up”, in case there were some K’nex pieces on the ground.* If any team left any pieces on the ground then they could lose a point.

TEAMS

~There were two teams of six people, but because we have a new student in our class, Eric, we now have one team of six and one team of seven.

Team of six

~Courtney (me) ~Valentina ~Karin ~Chiara ~David ~Jakub

Team of seven

~Tamara ~Emilija ~Ghazaleh ~Davide ~Ben ~Nathan ~Eric

POINTS

~Since I didn’t mention this before, each team needs to have 35 points to be able to build the compound machine, which is a machine that contains all of the simple machines that we learned about= lever, screws, wheel and axle, wedge, pulley, inclined plane.

Thursday's class

First we talked about simple machines, including the

compound machine. If we finished all of the simple machines, we would be able to start the compound machine this Thursday (April, 21, 2011). This was a very short discussion which didn't last long because we wanted to work on building the simple machines. Before we started building, Ms. D gave us a few tips about blogging, and the Reflection post, and then we started building!!

A few teammates testing out their machine

Friday's short block...

On Friday we were very busy, since

we didn't have much time to build.

Ms. D. gave us a few instructions

about the blog and the compound

machine, and then we all started

building.

This picture is the 'Cookie Monster

team', the other team's picture is the

first picture on this blog.

This picture is of Karin and I

(Courtney) waiting in line to

answer questions for Ms. D.

Reflection Post

This quarter for science, I think that I did pretty well for my scribe post. I think that I improved from last quarter but I still think that I could have done better. Some things that I could improve upon for next quarter are things like:

• Color


• Science


• Depth


• Explanaton

Some things that I did well on are things like

• Color


• Explanation


• Pictures


• Links

But I think that I could do better next quarter. Some things I liked about Blogger are that I can read about what we did in class if I was sick, and that I get to let other people see what we did. Some things that I did not like about blogger is that it does not spell check, and it does not come out as you planned sometimes, but other times it works out just fine.
