Credible Scientist – G8 Science U1 Reflection

What makes a credible scientist?

Based on this unit, using the data you actually collected and interpreting and reflecting on that makes you a credible scientists. Reflecting on what we collected from our experiments can let us be a credible scientist because all of our data are collected from a real experiment. Us using real data makes us a very credible science because every part of our report is true.

Why is the scientific ‘way of knowing’ used in medicine compared to other ways of knowing?

Being credible is important and used in medicine because if you work in medicine, it’s a subject that affects how people will react to the medicine. If you do not react correctly to the data you collected, it might make people sicker or even worse, pass away because they’ve been using the wrong kind of medicine the whole time. On the contrary, if you reflect on true data, it will make the local community better and make people feel better.

How would you improve your seed dispersal investigation if you were to repeat it?

If I were to repeat it, I would change the range of the independent variable because we can’t tell the difference of the shapes while doing the experiment. I would change the range by making the range wider such as starting with 100 degrees, then 110, 120, 130, and so on. I would also change the way I communicate the method because some parts of the method isn’t that clear, it will make people that didn’t know about this experiment at all confused.



Unit 2 Science Reflection – How is Everything Connected


Unit name: Ecosystem

Key Concept: Systems

Global Context: Human impact on the environment


For Science Unit 2, we studied about the ecosystem and how everything in it is connected. From unit activities, we learned about ecosystem vocabulary such as biotic factors and abiotic factors. I also did research and learned about human impacts on ecosystem such as doing presentations on bees, sunscreen and marine life etc. During the research, I learned when I do the presentation, I must include details about the problem, the solution of the problem, and implications of science. At the end of the unit, we collaborated with a grade 4 class and taught them knowledge about global problems. Our group did a presentation and game about the air quality in Hong Kong. The first group was really engaged and seems very excited when we are playing the game, which is jeopardy.

    1. How did you research and create the poster, presentation, and vidcast?

For research, I will find reliable sources such as websites that’s just about science in it. Most of the time, we have links to websites for research linked on the instruction sheet. I will divide my research in three parts, the problem, the solution, and implications of science. According to the chart our teacher gave us, we need to find important information from the source and summarise it in our own words. After doing research, we need to cite all the source we used. For creating, I often put the summarised information on my script but for presentations, I only put important point and pictures on my slide, all the words that I need to say are on my script, I used the same idea for my vidcast and recorded myself on Quick Time Player. For creating the poster, I did it about glaciers, specifically Fox Glacier located in New Zealand. I did research on tourist websites, wikipedia, and some from the school’s database, the poster turned out pretty well as a hard copy.

2. How did you prepare for the quiz?

I did a quiz on ecosystem during the unit. For the quiz, I mainly reviewed the vocabulary for ecosystems and the meaning of them. I knew this is a Crit A test so we will be tested on these stuff. Also, I reviewed the flashcards that our teacher posted online so we can do a self-test ourselves so we know what we should mostly study for.

3. How did you communicate and collaborate for the Grade 4 activity?

For the Grade 4 activity, my main job in my group is doing research and creating slides. The main point of communicating is through our group’s presentation. For the work periods, I also planned on what should we do as an wrap-up activity at the end. During our presentation with the Grade 4, our team didn’t read the slides, we let the Grade 4 read the slides so the whole thing won’t be so boring. Personally, I think I communicated really well through my presentation because I included the questions and answers from the jeopardy game (game we played together at the end) so the Grade 4s know where to find answers or where did they come from.


Cardboard Project Reflection

For science class, we have been working on our cardboard project. This project is mainly about making an actual object for somebody in the school but it is using cardboard.

Project Photos!

Here is a photo of our final project:

Here’s our prototypes:

Our Goals!

We planned to to make a coffee chest table for our science project. We would like to put this project to Ms. Stewart’s guidance office. We made our table by cardboard because that is the only material we can use. But also, we put paint on it to make it prettier. We made this project so we could get a better hold of structure and forces. We can show what we have learned before we made this project.

How did we use science?

I learned how to consider different elements in science when our group are planning our final design. We have to consider about how to make it stable, how to make it last longer because cardboard can’t last long. For me, I tested how to make the top stable for my prototypes. For the paper cardboard prototype, I made all three designs for the top. When I finished making those prototypes, I used masses to test how much weight it can stand. The one that can stand the most weight is the strongest. I used these results when me and my group mates discussed about the final design. I stated that they can use my top if they think it is the strongest.

Personal Questions!

  • How did you improve as a learner?

I think the best thing I learned is to how to do team evaluation. I think that’s the part I’ve learned the most. I can get ideas from my teammates of what we should use and what we shouldn’t based on prototype testing failures and success. Also, this project is also about time management. I think I need improvement on this. During the project, some of my prototype results are overdue because I didn’t manage my time correctly. Also, during the group final building, we need to use extra time to finish it because of time management.
