"What Kind of Cell Would You Like to Be and Why?"

What type of cell, and why?
Types of cell :
  • Prokaryotic: Are cells that has no nucleus, has no organelles and are really tiny, it is single celled. An example of prokaryotic cells is bacteria. 

1.Plasma membrane
2.Capsule
3.cell membrane
4.DNA (which has the nucleoid region)
5. Ribosomes
6.Pilli
7.Flagella


  • Eukaryotic: Are cells that has a nucleus, and has organelles, they are tiny, but a little bigger than Porkaryotic cells. 
            There are two types of eukaryotic cells, one is animal and the other is plant
The animal cell reproduces by sexual reproduction, while plant cells reproduce by photosynthesis, which is a process where the plant absorbs light and is able to make the photosynthesis, by herself. 


My opinion - 
In my opinion, if I could choose which one I would like to be, I would choose to be a Prokariotic cell. 
Some positive things of being a Prokaryotic cell  is that you will be really protected, because you have the Capsule, then the Cell Wall, then the Cell Membrane. So if you are a bacteria, you are always very well protected. That's why sometimes is hard killing the bacterias inside of you, and you get sick. Another positive point of view of being a Prokariotic cell is that you can move! Because Prokariotic cells have flagellum, which are tail-like projections that are made for locomotion. It helps the cell to move, to go where it wants to.
Therefor, there is a negative point on being a Prokariotic cell, you will always be single celled, which mean you will always be alone. You will never join with other cells to make a bigger particle, you will always be by yourself. Forever alone. This is a negative point of view, because I would prefer having companies than being alone.

Meals on Wheels Project

Meals on Wheels Project

Last week, we worked in a project called "Meals on Wheels". In this project we were supposed to form teams, and each them would analyse 3 different diet menus, all the groups had the same menus. In the project, we were pretending we were nutritionists. We were hired by the company, called "Meals on Wheels" and we had to choose 2 of the 3 menus that they gave us. Explain why we thought these two menus were the best ones for diet. 

To be able to complete these project, we had to know all the nutrients our body needs, their functions and know in which food we could find each nutrient. So we could know what the menu's food contained. 

  • 1st day of project 
In the first day, we were separated into groups. I was in the Yellow team, and other 3 members, however one of the members was absent the whole week. So, we had 3 people in the group. In the first day, we had to plan how we were going to run this project. We divided each menu, for each one. So each one had a menu, and from that menu you had to analyze it, and research the foods in the menu. Each person had to discover if it was a long-term or shot-term diet menu, also know if the menu was healthy, and search more facts about the menu. For example: Know what the menu had cut from the nutrients.
After that, we planned that we were going to make a power point presentation, and a poster. We made a plan of how organizing the power point and the poster. That's all we did in the first day, we planned our project. 

  • 2nd day of project 
In the second day, we went to the library and used the computer to search information of our menu. Each one had their way to search it, and my way was to research each food in the meals and see what nutrient was in that food. In the end, I discovered that my diet menu was a type of menu that took out a lot of nutrients. It was a menu that didn't have much nutrients, like fat, proteins. It had other nutrients like carbohydrates, a lot of water, vitamins and minerals. It had a lot of water because every lunch and dinner you had to eat Cabbage soup, and you could drink water or juice. This diet was and still is recommended only for those who wants to lose a lot of weight in a short-period of time. My type of diet menu, you can't  work it like a long-term diet because it lacks a lot of nutrients, and its not healthy to stay a long time without the essential nutrients that we need in our body.
Each one discovered new things about their diet, we took notes, and the class ended this way.

  • 3rd day of project
In the third day of the project we combined all the information we had and started doing the power point. While one person was writing their part on the power point, the other was starting to do the poster and the other was  searching pictures for our power point and poster. We worked hard, like a team. Each one always had a work to do. Then we changed places, one went to the computer to do the power point, while the other was finishing the poster and the other looking for more pictures. The third day passed really fast, and didn' have finished our work, that meant we would have to finish for homework. That's what we did, in the weekend one person finished the poster, while the other finished the power point and the other printed the pictures for the poster.
Monday was the day of the presentation, and we weren't done, but in break time we met together and glued the pictures and we were done with our project. 

What I learned -
While doing this project, I revised a lot of information about the nutrients, for example : that carbohydrates were the main source of energy, that fat insulated and protected our organs, even though it's not good to have too much fat, that can turn out to be a problem, like a disease. Therefore, I did not only revise, but I learned new things too. For example : that carbohydrates were the first nutrient to be digested in our system, and other things too. 
This project didn't only give me knowledge of the subject, but gave me life lessons too, like teamwork and organization. Because we always worked like a team, so we could do this project in a way that everyone would be pleased. We tried to use our time wisely, and divide works so we could finish it faster. We were organized, because we made a plan in the beginning, and that's the plan we had till the end.

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

First Days

Day 1
In the first day os school, we did some different things than the other usual classes. In Integrated Science 3 we did the Marshmallow Challenge. We were separated into groups of four and the challenge was to contruct the highest freestanding structure with a marshmallow on top of it, in 18 minutes. She gave us some objects that we could use and it was :

- 1yard string
- 1yard tape
- 1 marshmallow
- 20 sticks of spaghetti





Most of the groups failed to do it, and only 2 groups made it. It was hard because we had made it in the wrong way. We should had putted the Marshmallow first and try to do the tower with the marshmallow, but most of the teams made all the tower and in putted the marshmallow, so the weight wasn't balanced and most of the tower got destroyed in the last minute, because everyone wasin a rush trying to make the tower stay still.


After this we watched a video, and it showed how the kindergarden kids were better than the teenagers and some adults. Because they always did all the proccess with the Marshmallow on top of it. Therefore the teenagers and some adults tries planning everything first, but the kids don't really think that way. They just try, try and try to make the tower stay up. However, they showed the enginners and the arquitets doing it too, of course they were good at that, and they made the tower stay up, because it is their job and hopefully they knew how to do it. Another reason is because they have more knowledge and experience than us.

Day 2
In the second day, we talked about some artists that were really famous, and still is. We talked about how the practiced and putted a lot of effort on what they wanted to do. That's why they became so famous and succesful on what they did. We read articles about artists like Beatles, Bill Gates etc. Because they really spent a lot of time practicing on what they wanted to do; We learned that is not that someone borns succesful but, they try hard and puts a lot of effort on what they like. You have to at least practice it 10,000 hours to become succesful on something. That's what we did on the second day.

Plans
I made some plans for this year, which are: 
1. I want to study harder, because it starts counting on my college application.
2. Give my best in all projects and homeworks, so I can keep all my grades above B. 
3. Pay attention in the classes, and participate more in class discussions.
4. But at the same time,participate in various after school or extra activities.
