What Kind of Cell Would I like To Be

If I could be a cell, I would be a prokaryotic cell. I would like to be a prokaryotic cell because they are very simple single cells, they don't have organelles. Although they are very simple, they perform many important functions; serve as decomposers, agents of fermentation, play an important role in our own digestive system. They are really small and some of them use sulfur instead of oxygen in their metabolism. Some of them have a capsule that is an additional protection that also helps the cell adhere to surfaces and nutrients. They have flagella, structures made of protein, that enables them to move. Prokaryotic cells divide by binary function and are the most primitive forms of life on Earth. 


If I was a prokaryotic cell I wouldn't have to rely on others cells and would be able to move. I wouldn't depend on oxygen to live and although I would be simple and small I would be essential for life on Earth. I also would be resistant and be the oldest organism on Earth, which proves that I am the perfect organism as I am on Earth for so much time.

"Meals on Wheels" Project

In this week we had to work in groups and analyze 3 menus to see in each of the categories they fit in; one week quick weight loss menu or healthy and balanced menu that fits a long term weight loss program. The menus were very distinct and by doing some research we were able to identify what nutrients were missing, and what nutrients were in exaggerated amounts in the menus. 
We had some difficulties when we started the project, but with the teacher's help we were able to do it and actually learn. This project was a great opportunity to experience what a nutritionist does and see if we liked, so maybe in the future we will know if that is what we want to do. In the presentation below you can see what we learned while doing this project.

With this project I could learn a lot about proteins, lipids and carbohydrates. I could learn how to apply them in a diet and why they are essential to our bodies. I also could practice my leadership skills, as I was the leader of he group. I think it was a great project and we should definitely do more things like this, where we can learn, help our group members and also receive help from them.

What was the purpose of these first two days of school and what are my plans for this year?


The first two days of school meant a fresh start, it meant that we would need to work hard because this year will already reflect in our future. I always thought science was the hardest class but these first two days were pretty fun. 


In the first science class of the year we did the marshmallow challenge where we needed to work in groups of four to manage to put a marshmallow in the top of a tower made of spaghetti. To complete this challenge we only had 1 marshmallow, 20 sticks of spaghettis, one yard of tape and one yard of string.  We only had 18 minutes to complete this challenge with our group mates. It was kind of hard because my group started with the wrong foot cutting almost all the spaghetti sticks. We managed to build a tower, at the end it was to high for its bad structure and as we just included the marshmallow at the end it immediately went wrong. The whole tower fell and there was no time to fix it.



At the end of the challenge we saw some numbers about it and we discovered that kindergarten students do better than average adults. The thing is that they start building up by using the marshmallow while adults leave the marshmallow for the end having less time to fix if anything goes wrong. 









In the second day we saw a video that teached us to be persistent in anything we do and that to something work out there is no other way to be done than by working our ass off. At the end of class the teacher read something that inspired me; she read that to be really good at something you need to have 10,000 hours of practice. This theory was proven and anyone known because it was really good at something, Bill Gates, The Beatles, Tiger Woods, Beethoven, had these 10,000 hours of practice.


I think these two first had the purpose to introduce the course, letting us know not only what we will study but also what we need to do to succeed in it. It inspired us to work well and start the year with the right foot. Also we had the chance to work with our class mates and get to know how they work and what will be expected of group work this year. 


My plans for this year are to work really hard and learn the much as I can because I have a really good teacher and science is a really interesting subject. I hope that I will finish the year or semester with a good grade by being focused, persistent and hard working. I will try to take advantage from this course and try my best so that by the end I will be proud of myself.
