Neuron Post- Psychology 12

Dendrites  – They are made to receive and communicate to other cells. They use an electrochemical charges to communicate to the cell body. These look like trees which helps increase the area of the cell body. 

Axon-  An Axon is almost like a very thin and long cable which runs through your brain. Within this cable, It sections off into different parts. This is almost like a pathway for neutrons to transport to other neutrons.

Cell body- The cell body is where the nucleus is contained. The cell body connects to the “dendrites” which would travel through the axon to send messages to the other neurones.

Myelin Sheath- this is a layer over and forms around your nerves in your brain. This allows electrical impulses to get to other cells through the nerve at a quick speed.

Nodes of Ranvier- They allow the ions to go in and out of the neutron which sends electrical signals.

Terminal branches of axon- These are the end of the branches coming from the axon, the end of the branch is what is called the “terminal”. This is when a cell body is attached to another neutron.

  • All of these are connected through the axon with branches.
  • The Schwann cells are found in he central nervous system, their job is to protect and form a “layer” or shell around the neuron.

the Astrocytes are found in the central nervous system. 

The ependymal are found in the ventricles cells.  

Rube Goldburg Science Project 2020

For this assignment we had to create an obstacle coarse that would show how to complete a task of our choice. We chose to get a marble into a hole as our task. Our coarse went throughout the counter down onto a lower table, and then onto the floor. We had 3 levels of a coarse. Our coarse we started by using a piece of food to bump the piece down the incline to hit jingo pieces until a marble fell through the tunnel. Then it reached the 2nd level which knocked down another row of jenga knocking a marble into a hat which made the folder open up. That knocked over another large row of jenga up another incline to knock a larger marble into the last hole. Once the marble was knocked over that was the end of our task.

We also had 4 energy transformations in our project which were: 

Chemical to mechanical

mechanical to mechanical

mechanical to sound

mechanical to gravitational. 

3 simple machines:

incline plane

screw and

wheel and axle.

Desmos Self Portrait-Hannelie Jogha

This assignment we used demos as a tool to help us with our equations and seeing how each number fits into the graphing chart. We created a self portrait character that was made up of shapes that we needed. My character looks a little scary, but looks like it has a fun personality which I think represents me well. I used a blue and green outlining because those are my two favourite colours and I tried to make the other colours represent my natural hair and eye colours.

Write up- This assignment we had to create a “self portrait” on demos graphing. This was challenging to figure out, but once you get started you start to see how it works it started to get a lot easier to form what you wanted. While making the portrait I found it most challenging to balance it all and get the sizes to be the exact size and space you want it in. For example, trying to get the hair to reach around your head, and not have it stick out or have it end in different places was one thing I had a lot of challenges with. But once you put in the coordinates of where you wanted to end it seemed to come together. I used different shapes when trying to create a portrait. I used linear, quadric, and circle reactions to create my character. I mostly used lines and circles to put my face together (eyes, brows, nose, mouth etc. )  Overall, this assignment really showed how equations can create many different shapes/lines and how playing around with the numbers made a huge difference in the graphing.

Wonder Project 1- Science 10

Question- As humans, would we be able to permanently colonize and live on another planet? What would life look like? 

We always hear about how earth is going to end in the near future, and how we won’t have a place to live. But what if we could move and colonize to another planet? Would it be possible? How would we live? Is it safe? How would it affect us? Those are all questions that come to mind when this topic comes up. I have researched to find out if it was possible to colonize on the moon or another planet. But most importantly what would life look like?

Living on the moon-

The moon has a very dusty rough surface, making it not the best place to colonize. Scientists have reported that the moon Is not a “pleasant” place to live compared to earth. The moon has Lunar days and nights, that occurs when the moon is rotating on its axis in line with the sun. The lunar times last 14 days each. The average temperature during the Lunar days would be around 123 degrees Celsius. During Lunar nights it can get as cold as -233 degrees Celsius. Which does not make it suitable for us to be living on. Some parts of the moon have ice, water, and no light during because of how the sun orbits around. 

By these facts, it shows that the moon is not the most convenient place to colonize. If we ended up colonizing we would need to have heaters to keep is from freezing, and air conditioners to keep us from over heating. This would take a toll in our daily lives. 

Living on Mars-

Unlike other planets, Mars has seasons depending on its axis and where you are located. The southern part of mars, which is away from the sun has very cold winters, and the northern part has very hot summers. The northern part has 7 Months of spring, 6 months of summer, 5 months of fall, 4 months of winter. A year on mars is longer than a year on earth. About a 5-month difference. That means that a day on Mars is over 24 hours, so time is a little off.

Living on mars would be more challenging than living on the moon due to the lack of information on Mars. Mars is a place where we have had very little exploration on, and lack off information. Mars is shown to be a lot more challenging to live on then the moon. 

Supplies-

Living in space would be a very challenging time due to needing so much supplies to just survive. As humans we would need a craft or our “homes” to have oxygen for us to breathe that would circulate and keep us alive. We would have to have an oxygen tank while being outside of the craft. 

Another thing we would need is food and water. Food and water are another necessity that we would need. Because of science developing you can now take more foods with you. You used to be able to only take freeze-dried food and now you have more varieties.

 

Conclusion- 

In conclusion, This question is a tough one, because we will never truly know what life would be like unless we actually travel. My research has shown that earth is a much safer place for humans and wildlife to be living in.

Scientists believe that the moon especially, is a planet that we would be able to one day colonize on. The moon is a place where we could build, develop and live on. But the risks, dangers, and life style is not the best decision in the present. But in the future this could be a possibility. But as of now, we need a lot more research and space exploration.

Video- Will we ever be able to colonize the moon?

Math Reflection- Term 1

This math term, was not a great term for me. This year, my anxiety during school was getting a lot worse then it has in the past. Math is not hard for me and I grasp onto concepts and strategies easily once I am shown how to complete the steps. I complete all my homework and understand what we are doing in class. But the unit tests really do throw me off and everything I know runs away from me. I can easily show my knowledge through non-stressful things like Homework or projects. But as soon and its a test I am not able to solve the equations I would have no problem doing if it was not a test. Because our grades are based on our unit tests, and I do not deal well with tests my goal is going to try not to let my anxiety get in the way of me passing this class when I can understand what we are learning. If I can keep my anxiety levels down I would hope I can do better on my tests. It is a lot easier for me to show my understanding using ways that don’t stress me out, like a homework sheet, or a small quiz that we have a night to prepare for etc. I just hope when we come back we will have more options for people who are like me who can’t do tests and we at least have a chance of doing well in math 9.
