CREST Final Reflection

This week we finished up our CREST project and our reflection presentation. My CREST project was about “How engineers are making space technology more efficient?”, and I really enjoyed spending my time on it.

Overall I think that my project was successful as I managed to meet my main aim, which was to inform others about the advancements that engineers are making to space travel. I definitely think that my project will be able to educate others about how space travel has been advancing, and how it might be in the future. Another reason why I believe my project is successful is because the information is presented in an engaging manner – a Prezi presentation. In my presentation, the information is presented in a concise manner, and it contains many visuals, hence it will be able to engage my audience well.

However, there are quite a few things that didn’t go as planned, hence diminishing the success of my project. Firstly, I found it hard to find relevant research on my topic, more specifically, on how engineers are making the fuel used in space technology more efficient. This led me to spend a lot of time on research, hence I ended up having less time to put together my final project, and it was very rushed, therefore my project was not at the best level it could be at. I also think I could have improved my communication, because I found it quite hard to cut down on words and make my presentation concise, therefore I ended up removing a lot of information from my presentation. This means that some scientific information in my presentation is not explained properly, the reasoning behind my inferences are not thoroughly explained. This might make it harder for my audience to understand my presentation, hence diminishing the success of my project.

This project has led me to learn a lot of things about the wider world, and also about myself. From this project, I have a deeper understanding of how rockets provide propulsion for a spacecraft, and also about the evolution of space technology and how engineers can improve it to become cheaper and more efficient. For example, by using reusable spacecrafts, engineers will be able to significantly reduce costs and waste, hence increasing efficiency. This is because normal spacecrafts are expensive to build, and are thrown away after each flight, hence by using reusable spacecrafts, a new spacecraft don’t have to build for every launch, therefore reducing costs and waste.

From this project, I learn a lot about myself as well, for example, I learnt that time management is a skill I need to work on, I actually left this project for the last minute, hence it was very rushed, and it wasn’t the best level it could have been. If I had made a plan and managed my time properly, then my project would have been much better. On the other hand, I also learnt that I am willing to learn, and enjoy learning more about things that I am interested in. Since I was interested in this topic – space technology – I found it easy to be motivated to do work, despite not having much time to finish my project.

The information that I have provided to the audience that view my presentation will allow them to have a deeper understanding of how space technology works, some challenges that engineers face in relation to space technology, and also about how space technology has improved through the years. In my presentation, I also talked about how engineers might make space technology more efficient in the future, hence this allows the audience to anticipate a future where space technology is more efficient, and they will also know potential ways in which space technology might develop.

If I were to do this project again, then I definitely would put much more effort into and actually make a plan of how to managed my time efficiently, so that I don’t end up doing the project at the last minute. I also think that I would a different method of presenting my work, such as a video documentary. This is so that I will be able to convey more information to my audience in an engaging manner. I would also do more research so that the explanations provided in my presentation would be more thorough and easy to understand.

If I were to develop this project in the future, then I would do research on how space technology has improved from now, and limitations that prevent engineers form making space travel more efficient and cheaper. I would also look into the different materials that can be used to create space technology and how that will affect the efficiency of a spacecraft.

Overall, I definitely enjoyed spending time on this project since this topic – space technology – is one that interests me a lot. This is because aerospace engineering is a very interesting career that I might pursue in the future. I hope that there will be cheaper and more efficient space technology being used in the future, and if not, I hope that I will be able to play a part in making space technology more efficient.

Reflection #1 (CREST Project)

My project is about how engineers are making space travel more efficient. During the start of 2020, I read multiple books about space, which sparked my interest in space, therefore I chose to do my project on space travel. Another reason why I chose to do this project on space travel is because I feel like space travel and exploration will be a big part of our future, hence I want to learn more about how space travel is getting better, and make predictions on how it might improve in the future. 

Initially, I wanted to make a poster on how engineers are making space travel sustainable, however now I am focusing on how engineers have developed space travel to make it more efficient. Hence I want to make a documentary or a slideshow showing a timeline of how engineers made space travel more efficient, therefore showing my creativity.

My next step for this project is research. I feel like there may be some difficulty in finding past designs of space travel and how it was less efficient than current space travel. Another challenge might be making predictions on how space travel will improve in the future.

Gallery Walk (Science)

How has your thinking on this project been influence by others?

  • Before I was pretty unsure about my questions and if it would be interesting, but through these comments, I have gained some confidence in my question and I think that this will be my final question
  • I can have a wider audience for my project (maybe UWCSEA middle school + high school + parents)
  • I should make my aims more specific and clear (not so broad) so that this project is easier for me and my audience to understand
  • In order to make my findings more reliable, I should find examples from the past of different engineers and how space technology has advanced and become more efficient/sustainable

Mood Board – Space

6 possible connected science ideas:

  • Making space travel more efficient (can travel longer distances faster)
  • Finding a more sustainable fuel for spaceships (renewable vs non-renewable)
  • Finding other Earth-like planets for a possible living???
  • Figuring out a way humans can be more adapted for space travel
  • Figuring out a way to communicate with aliens
  • Trying to understand more about the formation of planets, and the beginning of the Universe

CREST Lesson 2 – SWOT Analysis (Task 3)

Strengths:

  • I am good at taking a leadership role and delegating roles to others
  • I am a good communicator if a problem arises then I will communicate it to my group members
  • I am also a good problem solver
  • I am also willing to learn

Weaknesses:

  • Time management is one of my weaknesses as I tend to leave my tasks to the last minute
  • Being productive is another one of my weaknesses since I easily get distracted, hence not finishing my work and being productive
  • It is usually hard for me to come up with an idea for my projects, so I tend to spend too many lessons just figuring out an idea
  • Collaborating with people I dislike is a great challenge for me, so I am happy that this science fair is an individual project

Opportunities:

  • My goal from this is to learn something new and to enjoy the process
  • I also want to work on my time management skills by setting targets and spreading the work evenly over the time we have rather than doing it last minute
  • An opportunity from this is that I can learn more about the things that I am interested in, and this could potentially help with IB

Threats:

  • Going off task and being unproductive is my biggest threat
  • Another threat is all the other excessive work that the other teachers are giving us since this could lead me to having less time to spend on the science project

Science Reflection (#FailWell)

I felt really disappointed when I got my science exam back. This is because I made really silly mistakes in the exam which could have easily been avoided during the exam if I wasn’t feeling so cocky and confident during the moment. After the exam, I felt like I did well during my exam, but my results state otherwise. I am pretty sure that this is the worst science test that I have taken in the whole grade 9 course, usually I ace the tests, or get 92% at the lowest, but in this test I only got 91.2%. A lot of people will say “oh you did so well”, well I think otherwise, I think that I did pretty bad and I could have done much better.

Two things that I have learnt about exam techniques, specifically science exams, is that the only thing that is actually needed for a science exam is the keyword. As long as you know the keyword, and you know how to phrase it into different sentences, you will be guaranteed full marks for the question. This was shown in the first question itself, I lost a mark because I didn’t state the keyword that was needed for the answer – the solution is more dilute than the leaf – instead I wrote – the solution has a higher water potential than the leaf – which didn’t give me the mark as I didn’t state the necessary keywords needed. The second thing that I have learnt about exam technique is that we always have to be accurate with our reading, there usually won’t be a range of different answers when the question asks for a reading. This was shown in question number 3, where I somehow managed to get the reading off by .1, even though the scale was right in front of me. I have made this same mistake in a few of my science tests, and I honestly don’t know why I keep getting the readings wrong, maybe I just need to focus and be more in the moment when taking exams.

As I stated in the previous paragraph, keywords are EVERYTHING in science, and I mean everything. The only way to get marks in science is by getting the correct keywords, even if you explained the question properly, you won’t get marks unless you have the specific keywords. In biology, if the question asks you about plant cells put in water (or something within those lines), then osmosis is guaranteed to be one of the keywords. A few other keywords for these types of questions will be – dilute/concentrated, water potential, down a water potential gradient, into the cell/out of the cell. For chemistry, if the question is talking about the rate of reaction then a few keywords will be – collisions, more/less frequent collisions, activation energy, successful collision. If the question is about physics and about things like force and acceleration, you should always remember that if the forces acting on an object are unbalanced, then the object will accelerate at a constant rate, it will not accelerate and an increasing rate.

3 specific mistakes that I have made which shows misunderstanding in 3 concepts are:

  1. (5a) I wrote that oxide is OH instead of O. This was a misunderstanding as I thought that a hydroxide and an oxide were both the same.
  2. (3dii) I wrote that since the values don’t go up by the same ratios, they are not directly proportional, but my misconception was that we need to use the evidence given to us, such as the table, and that we have to be more specific about how the data values show that it is not directly proportional. An ideal answer to this question would be the data values in the table show that the values for Power do not double as the values for Current doubles. My main misconception in this question is that I thought we didn’t have to be specific, so I made my answer very broad.
  3. (8biii) In this question, I wrote that a difference between boiling and evaporation is that boiling produces bubbles, while evaporation does not. For some reason, I thought that this would be a valid answer but turns out that this is not, and that my answer is incorrect. The correct answer, in this case, would be evaporation is only happens at the surface, while boiling happens throughout the liquid // evaporation produces cooling, while boiling does not, etc. My main misconception was that I thought that boiling producing bubbles and evaporation not producing bubbles would be a legit answer.

Looking forward, there are many things that I have to keep in mind. I always have to remember to focus on the exam and to stay in the moment so that I don’t make silly and unnecessary errors. Another thing that I should keep doing in the future is past paper questions. For this exam, I felt pretty well prepared, but I didn’t do as well as I expected, but in the future exams, I will do much better by practising even more with past papers.

C2 TEST REFLECTION

We received our C2 – Structure and Bonding test back last week, and upon getting my test I was disappointed. Despite getting a good grade, I made lots of silly errors which I could have avoided if I had double checked my work. In total, I lost 5 marks, all in section B of the test.

In question 9c, I lot 2 marks because I wrote tetrahedral ionic instead of simple covalent. This wasn’t really a misunderstanding or a misconception, I just didn’t double check my work and I let my pride get the best of me, therefore I lost 2 marks by making that silly error.

In question 11c, I lost one mark because I didn’t specify a legit reason for why diamond is a very hard substance. I think that the reason why diamond is a hard substance is because each carbon atom in diamond forms 4 strong covalent bonds, forming a tetrahedral structure which is very rigid, therefore causing diamond to be very strong. I think the main reason why I lost a mark on this question is because I wasn’t really clear as to why diamond is very strong, even before the test.

In question 12c, I lost one mark because I wasn’t so sure about how the answer was meant to be structured, and I didn’t really know how to answer the question. I think a proper answer to question 12c would be because the electrostatic attraction in Lithium Oxide is greater than that of Lithium Chloride, therefore Lithium Oxide needs more energy to break the electrostatic attraction.

In question 13c, I lost one mark because I didn’t use the correct terminology. I feel like if I used the words, ‘destroy the intermolecular forces’, then I would’ve gotten the mark.

Overall, I could have avoided all of these silly mistakes and gotten better marks if I double checked my work.

Bonus: Chemical bonds are the INTRAmolecular forces, the forces within a molecule. It is the forces that bond to atoms together, forming a new compound. INTERmolecular forces are the forces holding molecules together, changing the state of matter that the compound is in.

C1 test reflection

okay, so today we got our C1 test back, and on receiving my test i felt really happy and satified as i got the grade that i wanted, and i did as well as i expected.

i was pleased to see that for question 3aii, i changed my answer from chlorine is a gas to chlorine is a metal, earning myself a u.

i could have explained my questions better and not be so nervous about getting my test back. i answered my questions with too much writing, and i could have minimalized my writing somehow.

for next time i need to remember to not stress about these little tests, and to study very hard so that i will do well on my other tests too.

i will fail well by eating ice cream being happy.

🙂

 

Mini-reflection (science)

okay so we got the grade back for the mini quiz and my feelings about the grade I got is 🙁 because I usually do really well in science, and to think that I lost marks because I didn’t use a ruler is pretty funny and it makes me feel 🙁

something I did well is that I used observations to answer question 2.

something I should work on is using a ruler.
