I learnt more about the astronomy club and my CCA mates. It was fun doing the activities to get to know my CCA mates, and I even made new friends. The presenters could explain the activities more clearly and improve crowd management. Overall, I am glad to meet and bond with my new CCA mates.
2 April 2025:
I learnt about the moon today, namely the lunar cycle. It was hard to understand at first, but I started to understand more as we continued. The presenters could be more engaging. I enjoyed the activities, such as Stellarium web. Overall, I enjoyed the first astronomy lesson and hope the rest of the lessons will be as fun.

Today, we gave presentations on what we learned during the lesson on 2 April. I got to work with my CCA mates to create and present our slides. I had a lot of fun putting the slides together, and it was a great opportunity to reflect on what we had learned in the previous lesson. Overall, it was an enjoyable and meaningful experience.

Today, I learned more about gravity and other interesting topics related to astronomy. Exploring how scientists study the universe and measure distances between stars and planets was fascinating. One thing that stood out to me was the idea of using light years instead of meters or kilometres when talking about space. At first, I didn’t understand why they wouldn’t just use regular units like meters, but now I get it — space is incredibly huge, and using meters would make the numbers too long and complicated. I also learned that light years show how far light travels in one year, about 9.46 trillion kilometres! That fact really helped me understand just how vast the universe is. I feel like I’ve learned a lot more about the scale of space and how scientists make sense of it all. Astronomy is definitely becoming one of my favourite topics.

Today, I learnt about radiation and length. If I could travel back in time, I would show leaders how the movement of stars and planets can help predict seasons, guide navigation, and signal the best times for planting or harvesting crops. I’d convince them it’s a powerful tool for smarter planning and decision-making by demonstrating how astronomy improves survival and prosperity. Radiation, especially in the form of light waves like infrared and radio waves, helps astronomers detect stars in the Milky Way. By observing this radiation with telescopes, scientists can map star locations, study their properties, and understand the structure of our galaxy.

Today, we learned about telescopes, including how to use and assemble them. I also discovered the different parts of a telescope, such as the finder scope. Three cool things I learned were how to assemble various types of telescopes, how to use the telescope properly and how to disassemble it. I can apply this knowledge during future stargazing events to set up the telescopes and use them effectively. I really enjoyed the activity and hope there will be more hands-on experiences like this in the future.
7 May 2025:
Today, we had a fun and exciting debate about which planet NASA should explore or conquer next. I enjoyed creating the slides and working with my group to prepare our arguments. It was thrilling to present our ideas and try to convince others, while hearing many creative and thoughtful points from my classmates. The debate helped me think more critically and speak more confidently. His laws of motion and gravity explained how celestial bodies move, forming the foundation of modern astrophysics.
14 May 2025:
Today, we built a moon base in Tinkercad, and I had a great time working on it with my friends. It was fun using our creativity to design a base. If I were to improve our design, I would make the structure look more realistic and detailed, and I would also add a reliable energy source, such as solar panels, to keep the base running smoothly. During the Universe Sandbox session, I learned that the moon is extremely cold, especially at night, so it would be essential to include a heating system to keep astronauts warm and safe.

Today, we summarised everything we learnt in Term 2. It was a good revision of what we learnt. I enjoyed the Kahoot because it was a fun and good way to remember what was taught. I think space bases on Mercury would likely be built underground or in permanently shadowed craters to protect against extreme temperatures and radiation, using advanced robotics and solar energy for construction and power.
2 July 2025:
Today was the first lesson of Term 3. It was nice to return to Astro and see my classmates again after the break. The atmosphere in class felt warm and familiar, which made it easy to settle back in. I found the activities fun and engaging. It was a great way to ease into the new term, and I’m looking forward to CCA.
23 July 2025:
Today we did fox hunting. It was fun to try and find the radio by walking around the school.It was also a good time to find it with my CCA mates. I think fox hunting works by using radio direction-finding techniques to locate the source of a hidden signal. I also think it’s useful in astronomy to find and remove sources of interference that could affect radio telescope observations.

Today we learnt about stars and trigonometry. It was fun figuring out what we knew could be used in astronomy. In astronomy, the sine and cosine rules help calculate distances and angles between celestial objects. The cosine rule helps determine angles or positions when two sides and an angle are known, aiding in navigation and measurements in space. We can find a star’s mass by looking at how it moves with a nearby star in a binary system. By measuring how fast they orbit each other and how far apart they are, we can calculate their masses. If the star is alone, estimate its mass by comparing its brightness and temperature to other stars.
13 August 2025:
Today, we learnt how stars form, from collapsing clouds of gas and dust to the start of nuclear fusion, and how starlight can be measured using techniques like spectroscopy. Beyond astronomy, spectroscopy is also used in environmental science to detect pollutants in air, water, and soil, and in environmental forensics to trace their sources and track their spread.
20 August 2025:
Today in class, we learnt about how stars age and the different stages they go through, like how they form, shine brightly, and eventually burn out. It was really interesting to see how something so far away can have such a long life cycle. I also realised how much science connects to the universe around us. I like getting bribed to do things. So yes, please give me candy as a reward, and I’ll happily keep learning.

Today we did fox hunting during CCA, and it was really fun working with my cca mates to track down the radio signal around the school. I enjoyed using teamwork and observation to figure out where it was hidden, and it felt like a great way to wrap up the last session of Term 3. After that, we had a quiz about the Sun, which was both fun and educational. What surprised me most was learning about sunspots, dark cooler patches on the Sun’s surface caused by magnetic fields. I never knew that some of them can even be bigger than Earth. Overall, it was a meaningful and memorable session.
