2 April 2025:
I learnt about solar and lunar eclipses and solar days. I felt excited when we played the booklet and was interested in Stellarium. I also felt excited when I saw the universe sandbox simulations. However, the presentation was not that engaging, and I already knew most of the topics stated, but overall, the presentation was good.
9 April 2025: We had to create a presentation about the things we learnt in the previous lesson. I had a fun time creating the presentation as I had to write down and put in images in an organised way and it was fun to do the booklet game at the start of the lesson. However I felt that we had too little time to do the presentation but overall I think that this lesson was fun and I also enjoyed seeing other people's presentations as well.
16 April 2025: I learnt about the 3 Kepler laws, and I felt excited when we played booklet. I also had a fun time doing the simulation. However, I felt that the presentations and questions could have been more interesting as I knew most of the things stated in the presentation, and I felt that the questions could have been harder, but overall, the lesson was good.
Why do you think scientists use lightyears instead of km in space?
km are too short to easily measure things At the scale of the universe.
Where do you think gravitational stuff is used in Singapore?
They are used when measuring weight.
I would ask them to use the stars and constellations to create a calendar.
We can detect the what direction the electromagnetic radiation emitted by stars is and use it to find them.
23 April 2025: I learnt about beta decay and constellations and I had a fun time answering the questions. However, I felt that some of the topics could be explained better as I felt that it was a little bit confusing. I also felt that the booklet game could have been better as it was laggy and the movements and collisions was janky but overall I think that the lesson was ok.
30 April 2025: I learnt about the parts of the telescope and how to assemble one. I had a very fun time learning how to assemble a telescope and this was also my first time seeing a telescope in real life so I felt very excited. I liked that instead of teaching the topics using slides they actually gave us a real life demonstration. I also felt excited when I got to look into a telescope as I never got to look into one before. Overall I think the lesson was great.
What are 3 cool things you learnt about telescopes and how can you apply them in future lessons?
I learnt about how to assemble to telesop
May 7 2025: We did a group presentation, and I had a fun time researching, creating the slides and seeing other people's slides. However, I felt that we could have done better if we had more time. There was also a presentation, and I learnt about early astronomy, but I felt that the presenter could have been louder, as I could not hear him clearly, and it was not very engaging. Overall, I think that this lesson was ok.
Who do you think had a greater influence in astronomy: Galileo or Newton?
Galileo. Although Newton invented his Laws of Motion and Law of Universal Gravitation and also conducted extensive experiments with optics, Galileo was the one who made good telescopic observations, contributed to the development of classical mechanics, improved various scientific instruments and proposed that the Sun is at the centre instead of the Earth. So, Galileo had a greater influence on astronomy during his era than Newton.
14 May 2025: We did a group activity, and we had to design a moon base. I think that the activity was ok, but I felt that the activity should have been individual work, as I find that it is difficult to express all of our ideas for designs to my groupmates. I also felt excited when the seniors used Universe Sandbox to demonstrate the topics. Overall, I think that this lesson was ok.
1.What are some improvements you would want to add to your moon base?
I would like to add interior details, a heater, a research lab, beds, air locks and a landscape.
2.how can you further improve the moon base with the information you have learnt in the universe sandbox?
I can add oxygen tanks.
21 may 2025: There was a summary and a kahoot quiz. I felt that the summary was great as we made many jokes however I think that the kahoot quiz should have been a booklet quiz instead. There was also a group activity and we had to design a mars base however I felt that we should have been given more time and it should have been individual work as I find it very hard to convey every single idea I have for the mars base to my group mates but overall I think that the lesson was ok.
How do you think spacebases will be built on mercury? Why?
I think we would have small domes connected together using tubes. Mercury has no oxygen on its surface so we would need an air tight base to prevent the oxygen to escape.
2 July 2025: I think that the presentation at the beginning of the CCA was good as they explained the concepts very well, and I also enjoyed when we got to take a look at Kerbal Space Program, as I found it very engaging and interesting while at the same time letting me learn more about the different components of a rocket. I also enjoyed the Booket game we played in class. So overall, I think that this lesson was good.
What do you think neutron star anatomy would be like?
I think it would only have a core and a corona since there is no fusion taking place.
What about red and white dwarf anatomy?
I think a white dwarf would only have a core and a corona, but a red dwarf would be similar to a normal star.
9 July 2025: We had a presentation, and I think that filling in the blanks made everyone pay more attention. However, I feel that the presentation could have been more engaging, and there could have been an activity as well, but overall, I think that this lesson was ok.
July 23 2025:
How do you think fox hunting works?
I think they sense radio waves.
What do you think are the applications of fox hunting in astronomy?
They can be used to find galaxies.
I think that the fox hunting activity that we did was extremely fun and engaging as we had to overcome the challenge by getting used to the feel of the fox hunting device and what to look out for. However, I feel that the activity could have been better if we could split up but overall I think the activity was very good.
August 6 2025:
How do you think you can apply the sine and cosine rule in real life?
I can use them to measure the lengths and angles between large distances.
How to measure the mass of a star?
You can look at how the star gravitationally effects the things around it.
Today I learnt about tangent, the sine rule and the cosine rule and I think that it was interesting when they taught me about the sine and cosine rules however I think it could have been more engaging and there could have been activities but overall I think that the lesson was ok.
Can stellar spectrometry be applied somewhere else?
It can be used to identify materials.
13 August 2025: Today I learnt about how stars are formed and stellar spectrometry. I was excited when we got to play booklet as it allowed us to learn the topics in a fun and engaging way however I think that the lesson overall could have been more engaging but overall I think that the lesson was ok.
20 August: Today we learnt about pulsars, neutron stars, black holes and how stars are important in the universe. The lesson was good and I enjoyed the booklet activity however I felt that the lesson could have more engaging but overall I think that the lesson was thrilling.
27 August 2025: Today we did fox hunting and we also had a presentation. I think the fox hunting activity was ok however I think that the presentation could have been more engaging and interesting. I also think that the quiz could have been done better as the questions were more difficult than usual but overall the lesson was ok.
What surprised you most about the sun today?
The thing that surprised me most about the sun today was how powerful it was and how much of a threat it could pose for us.
