After the first half of the semester my goal was to have more organized notes and be more organized in general. I was able to achieve this goal. A way I was able to stay organized was by making a list of the things I had to get done with the due dates for everything and when I would have time to complete them. This really helped contribute to my organization skills because I knew what I had to do and I could manage my time accordingly. I also was able to keep my notes better organized and was able to effectively use them to study for tests. Overall I think I achieved my goal but I do believe I can continue to improve at this in the future.

“What would happen when the sun explodes, how would it affect the surroundings and how can we prevent the explosion from happening?”
In order to be able to prevent the sun from exploding, we must find out why stars explode.
The reason why stars explode is due to them running out of fuel. This causes the unbalance of the force of heat pressure pushing outwards and the gravity pushing inwards toward the core of the star. When the pressure from the core of the star is not able to sustain gravitational force, it will cause a star to explode.
Red Giants
After the star runs out of its primary supply of hydrogen fuel it will turn into a red giant. The star then expands and the temperature drops, the star takes on a reddish color, hence the name. The temperature of the star can drop to between 3,100 and 6,700 degrees Fahrenheit and the diameter of the star can expand from 10 to 1,000 times. When stars turn into red giants there is no fuel that keeps the star producing energy and the core of the star contracts. Most red giants exit the stage of being a red giant and cause a supernova. The star can only create a supernova if the star is big enough, which the sun is not.
The End Of The Sun’s Life: What Would Happen?
The end of the sun’s life will occur when the sun will run out of hydrogen. The core of the star pushing against gravity allows the star not to collapse when the hydrogen supply runs out, gravity takes over. However, as I previously mentioned, the sun is not a big enough star to cause a supernova. The death of the sun will be much slower. The sun will swell into a red giant. When this happens the sun will run out of hydrogen and begin fusing heavier elements. Temperature in the core will continue to rise as the sun begins swallowing the closest planets, possibly including the earth. The planets consumed by the sun will then quickly evaporate. The expansion of the sun during the final phase would result in solar winds capable of stripping the earth of its magnetic field, removing our atmosphere and our protection from dangerous solar particles and the sun’s ultraviolet radiation. The final stages of the red giant phase would see the sun shooting materials from its outer layers and since the Earth would have no atmosphere, it will be bombarded with intense radiation from the dying sun without any protection, making the surface of the planet entirely inhospitable. All the planets in our solar system orbit around the sun and the death of the sun would throw off other planets that orbit around it. The orbits will likely expand and planets will be more distanced from the sun. If the earth were to be a surviving planet, like all other planets in our solar system, without a central star around which to orbit, Earth and all the other planets in our solar system would become free planets, drifting through space without anything anchoring them.
How do we prevent the death of the sun or prolong the sun’s life?
To prolong the sun’s life would mean to stop the sun’s hydrogen supply from running out. To do this we would need to find a way to channel the hydrogen from the outer layers into the center of the sun because the reason stars explode is because they run out of hydrogen fuel and if we can prevent that from happening, the sun’s life will be prolonged.

Midterm Self Assessment And Goal Setting – Science
The Pillar I chose To reflect on is personal responsibility. Some of my strengths are consistently attending class prepared for what we are learning. I regularly check one note and teams in order to know what we are doing in class each day so that I am organized. I also always make sure all my work is done and completed to a good quality. Another one of my strengths is being able to ask questions that help me clarify certain things. and be able to learn from my mistakes.
Something I would like to improve on in the future is using the legend in one note to mark my work. At certain times I just move on after I complete a question on a worksheet instead of making sure it is right, and fixing it if it isn’t. This will help me learn how to trace my mistakes and notice them so that I will not make them again. I will do this by when I have time, checking my answers and making sure they are right before moving on.
A goal I have is to write out my work more clearly and be more organized overall. As it is I write out all my steps, however sometimes it can get a bit messy and hard to read. I am going to try and make everything smaller and write it out in an organized way so that there is no confusion when it comes to reading my work. This will also make it easier to reference later on while I am studying. I could use different colors to refer to different things. this will help me study more easily and overall be more organized. By the end of the semester I will make all my future notes more organized and keep them in a folder so they are easy to access and not get lost.
