LA informative writing

The main topic of this semester was informative writing and we wrote a informative paper. My paper was about the life cycle of stars, and i think the topic really helped me improve writing this kind of papers.

what was the biggest success?

I think the procedure of having research notecards is very helpful, and so it was easy to write the actual paper. therefore i think that my biggest success was easily writing the paper, looking at the research notecards that i made.

what was the biggest difficulty?

My biggest difficulty was doing research. The information from the internet was very mixed up, and the information itself was very hard to understand and learn. I eventually learnt them but i felt like i took extra science classes! But after doing all the research, it was easy to write the actual paper.

what would you have done difficultly?

If I were to write another research paper, I would choose a easier subject to learn, yet which has a lot of information on the internet. Also, i will try to look for more reliable sources to successfully cite them.

In the sky, there are more than 100 billion stars, but none of them are the same. Some shine brighter, some are larger and hotter. They might be different because of their surroundings, for example, temperature differences or number of asteroids etc. But stars, like living things, also has a life cycle which changes their form through time.There are two different life cycles of stars, each with 5 stages. They both share the first stage, and develops their own cycles depending on their mass.

The destiny of the two stars lie on their birth from the clouds of dust , which is called a nebula. The first stage of a star is called a protostar. “A star begins its life as a cloud of gas, which is mostly hydrogen and helium. The particles experience a very weak attraction towards each other due to gravity. As the gas cloud becomes denser, the effect of gravity is to increase the pressure and temperature. As more gas is drawn in by the increasing gravity, the mass of the cloud increases and therefore so does its gravity.The increasing gravity compresses the gas further so that it becomes hotter and denser. It eventually becomes a protostar(NASA).” The protostar’s mass depends on how much resource is around the star because the more resource it collects and gathers, the higher the mass of the star becomes. There are two main types of stars, low mass stars and high mass stars(Khan).

The low mass stars live for a long time compared to the high mass stars. After being a protostar, the next step of the low mass star is a main sequence star: “the protostar changes into a main sequence star, which is the second major step of a star. The core fuses hydrogen and helium together, and keeps on burning(Space).” It spends 90% of it’s lifetime as a main sequence star until the core is hot enough to fuse helium into carbon, which is a heavier element. The energy produced by this process makes the star grow many times bigger than it’s normal size. This is the third step of a low mass star, called the red giant(@NolaTRedd). When the star gets too hot and large, the outer layer of the star blows off while the core shrinks to a white dwarf. The outer layer creates a large cloud of dust around the core. This is called is a planetary nebula, which is a minor conversion step form the red giant to white dwarf. The star stays as a planetary nebula for thousands of years(Ask). The white dwarf is typically made of carbon and oxygen(Khan). The white dwarf is still bright, but it doesn’t fuse elements anymore, causing it to cool down, becoming a black dwarf which doesn’t give light out. The universe’s existence is too short to prove the existence of the black dwarf. The black dwarf is the last stage of a star, and expels matter that forms a nebula, waiting to become a new star in the future(NASA).

High mass stars have a very short lifespan, living one to ten million years. High mass star’s second stage is also a main sequence star, but heavier and larger than the low mass main sequence star. It lives 90% of it’s life as a main sequence star then it becomes a huge star called a supergiant when it starts to produce heavier elements like iron. The star lives as a supergiant for 10% of it’s lifetime(@skyandtelescope). But because the star is too unstable due to its large mass and size, the outer shell explodes into a huge cloud of dust. “A supernova is an explosion of a massive supergiant star. It may shine with the brightness of 10 billion suns! The total energy output may be 1044 joules, as much as the total output of the sun during its 10 billion year lifetime.(NASA)” After this, the star’s core collapses into it’s own gravity because of its unstable state, gradually becoming compact until it’s mass is so high despite it’s size. It becomes a black hole. Not many stars become a black hole because they need to be very large to become one. The gravity is so strong that light cannot escape from it(Dunbar). But black hole is not the only choice, when they have a slightly lower mass to become a black hole, but still has a very large mass, they become a neutron star, which is very dim because it does not fuse any elements anymore.“When a star becomes a supernova, part of its original magnetic field is ejected in the gas that is ejected by the explosion. But some of the field, trapped as it is by its connection with charged plasma, collapses into the core of the star which is imploding to become the neutron star(Pulsar).” high mass star’s life cycle normally ends in the stage of a supernova and become nebula, but when they become a neutron star or a black hole, they last so long that there are only theories of how they die.

The life cycle of stars are very long. Low mass stars and high mass stars start as a protostar and becomes a main sequence. Then the low mass stars become a red giant, then a planetary nebula, white dwarf and a black dwarf in order. The high mass star become a supergiant, supernova, then either a black hole or a neutron star. But almost none of the 100 billion stars actually finished their life cycle, and there is no proof that the theories about them becoming a nebula again after death are true.

Science SLC

balloon demo:

  • I will show how air molecules move from high pressure to low pressure
  • I will set two balloons that hang to the ceiling, they will be about 10 cm apart.

Q: what do you think will happen?

–> their hypothesis

  • blow wind between the balloons


  • There are air molecules in this space, air molecules are small particles that make up air. They are equally distributed at most times. Also, where there is air molecules tightly packed is called a high pressured place, and where there is less air molecules, it’s called a low pressured place.
  • So, when I blow between the balloons, air molecules are blown away, making the area have less pressure than the rest of the room.
  • Air molecules move from high pressure to low pressure zones. Therefore the air molecules around the balloons try to come in between the balloons, pushing the balloons together.
  • This shows that air molecules move from high pressure to low pressure.

art chair sculpture

What will be easy?

it would be easy to color the chair with paint (at least easier than sculpting the chair)

What will be challenging?

it would be challenging to paper mache the hand part of my design and the bird

What ideas do you have already?

i have and idea that the color of the chair would be showing contrast between the freedom and it’s other side. dark and colorful, it would show that the top is freedom and the bottom is the opposite

Why do we use the design process and not just take our first idea?

because it will improve the idea and give ideas that you didn’t think of before, making the design better.

What are you looking forward to about this task? What topic are you thinking of? Why?

I’m looking forward to see the final chair done. the topic is freedom, because it looked like the best one between my other topics.

reflection of my progress grade:

I should try to put more details to my blog to be able to get better grades. I was expecting something around B+ for my progress of the chair, but I got a A for my blog, therefore it is good.

My timeline(plan):

1st class(next class 2/24): start plastering 3rd tentacle, it is quite long therefore cannot finish in one day

2nd class: finish plastering the 3rd tentacle, then start making a hand shape with paper mache (might change material)

3rd class: continue on making the hand

4th class: finish making the hand and attach to the chair, start making a bird with paper mache (might change material)

5th class: finish making bird and attach to chair

6th class: start painting chair form the bottom (dark colors)

7th class: painting

8th class: painting

9th class: finish painting and start making butterflies

10th class: finish making butterflies and attach them, try to add little details and finalize the chair for left time.

Eco-dome day 41


4th eco-dome building:

The eco-dome was made, this time there was only one plant (that is different from last time) and had nothing else except soil and 30 drops of water. Maybe simple things are better for the grasshopper.

  • still have the same small container
  • have round leaves
  • 30 drops of water
  • have soil that has lot of nutrient
  • soil isn’t pushed down
  • small grasshopper

We figured that because our dome is small, we should have a small grasshopper, therefore we found the smallest grasshopper we could find and put it in. The grasshopper was 1cm long from it’s front to back.

Now we hope the grasshopper survives during the whole break.

Eco-dome day 22

Observation of 2nd eco-dome:

The ground was full of water and the grasshopper was underwater, dead. The plants’ roots grew and turned white. The dome’s walls were clean unlike last time. The grasshoppers turned black again, and the leaves were not eaten. One of the grasshopper turned red, and one was black. Inside the dome was very moist. The eco-dome was pretty warm when opend.

Reflection of 2nd eco-dome:

The ground was full of water because last time we put in a lot of water, also, the grasshopper drowned themselves in the water. the water was about 1cm deep, which is quite deep for the grasshoppers. The white root that grew means there was too much water and not enough nutrients, the grasshopper that is red probably burned, and the black one probably rotted. The dome should be moist because of the amount of water put in.

Conclusion of 2nd eco-dome:

There shouldn’t be so much water in the dome, so next time I should put in less water into the dome so the grasshopper could survive, and the decrease of water will also help the plant grow a little bit. I think the water may have cleaned the dirt in the domes’ walls. We should put the dome in a shade next time so the dome could cool down, not burning the grasshopper like this time. The dome should be moist, but this time it was just too much water so ill put in a little less water.

Changes for 3rd eco-dome:

  • less water
  • have soil that has lot of nutrient (must)
  • have plastic foil that carries water at the top of dome, to keep the dome cool (I will call it water layer)

All the other components should be same.

Art blog

My final book page:


My job was to make a advertising poster, drawing zebra, drawing the background of my book page and lastly doing my lettering of the book page.

So the publicity job was the advertising poster and I gave it to ms Jardin. This is the poster:



the Skype call was very useful to share our ideas and we got to know more about each other so it was good



the website looks very professional, and made a poster to promote it. also, ill use facebook to promote it

Radical inventions debate

My debate statement: The toilet is a more radical invention than wheels (team con)

the con team was me and hieu

My jobs were timekeeper, debater, Judge, and moderator in chronological order.

This is the debate planning doc:


and this is the debate:


My reflection:

  1. From the research, preparation and the debates themselves, what did you learn about the art of persuasion? Please explain.

I learnt that it is very important to have debates and debates are not just improvised and needs a lot of research. I also learnt that debate is not as easy as i thought.

  1. How do you establish credibility as a debater? Explain fully.

We could research a lot about the opposition’s item so we could build a lot of rebuttals, and also researching a lot about our item will make us better at successfully blocking and attacking back a rebuttal from the opposition.

  1. What surprised you the most about your debate and/or the debate experience?

I was surprised that the opposition had so much to say and they were so well prepared that we couldn’t really think of a way to block their claims.

  1. What were you most proud of in your own debate?

I was proud that i finished my speech within 3 minutes, and said everything i planned to say

  1. What would be your next steps? Or in other words, what would you have done differently?

I would research more about both sides to build my rebuttals and also i would be more prepared to do the debate (because i didn’t prepare because i thought our debate was coming later, which was true until ms khambalia changed her mind)

Eco-dome day 37

Observation of 3rd eco-dome:

The grasshopper, which was left in the eco-dome for 14 days, was dead. Like last time, the outer shell was black like it was burnt. Also, dirt was everywhere as usual. Everything was similar to previous tests except the plant grew healthily and the dead grasshopper was larger than when it was first put in. The leaves were not eaten this time. The water layer at the top seemed to help because this time the inside temperature wasn’t warm.

Reflection of 3rd eco-dome:

Now that I have tried to do something about the black grasshopper, it doesn’t change. Therefore I can assume it actually didn’t burn. But it just rotted after it’s death. The plant grew healthily because of the water layer (I believe)

Conclusion of 3rd eco-dome:

This leaf is not a good food for the grasshopper because there was no sign of eaten leaves. Which I can assume that the grasshopper died by lack of food. The water layer at the top made by plastic foil seemed to help, and i believe it cooled the eco-dome down, and made the plant healthier. By the fact that the grasshopper got larger, i know that it was healthy and didn’t have any problem growing except there was no food for it. next time I should keep everything the same except putting in some food for the grasshopper. I also think the water layer kept the grasshopper safer because the ceiling of the container is very low, which the grasshopper could crash into when jumping, causing it to die. But by the water layer, the grasshopper wouldn’t die. Also, i should put in some more water, this time, 30 drops of water exactly, which will soak the soil a little more than last time.



Changes for next eco-dome:

Next time we should put in a different kind of plant and see if it eats the plant because the grasshopper didn’t eat the plant this time. Also, 30 drops of water would be good net time because this time there was no moist at all.
