I learned about solar and lunar eclipses and how they occur when the Sun, Earth, and Moon align. I also studied the Moon's phases, which change based on its position around Earth. I liked the blooket part as it was let us recap and revise about what we learnt in today's lesson and was also very fun. The bad part was people spamming reactions in the google meet. I liked playing around with the simulations as well. Overall, I think this lesson was quite fun and I feel glad I attended this lesson.

I spent some time reviewing the topics from the last lesson to reinforce my understanding, and my group also put together a google slides presentation to highlight and explain what we had learned in more detail. Before that, we also played blooket. I liked the blooket part as usual as it helped us revise about what we learnt last lesson and also does it in a very entertaining way. Overall, I think this lesson was decent and I feel glad I attended this lesson.

I learnt about orbits and gravity in today's lesson. Regarding the question "why do scientists use light years instead of km in space", my answer is scientists use light years instead of km in space is because it provides a more managable scale than km. I liked the blooket part which let us revise about today's lesson. Overall, I really liked this lesson as it was fun and I am happy I attended this lesson.

I learnt how to assemble and disassemble a telescope, and I also became familiar with the different parts of the telescope and their functions. In addition, I learnt about the inventor of the telescope and gained a better understanding of how it works overall. 3 cool things I learnt about telescopes is there are different eyepieces for telescopes, some telescopes are electronic and can find stars by itself, telescopes need multiple people to assemble and disassemble and telescopes can be earth or space-based. I can use this in stargazing events by asking people to help me assemble or disassemble a telescope. Overall, I liked this lesson and I am glad I attended this lesson.

I researched about the planets in outer space that are similar to Earth and are habitable. Some of these planets are Proxima Centauri b, Kepler-186f, Kepler-69c. My group spent some time making slides about Kepler-186f and why we think it is a great planet to spend money and colonise. We then presented the slides and answered questions regarding Kepler-186f. Regarding the question "who do you think had a greater influence in astronomy, Galileo or Newton", my answer is Galileo as he was the first to use a telescope systematically for astronomy and discovered the 4 largest moons of Jupiter, also known as the Galilean moons. Overall, I really liked this lesson and I am happy I attended this lesson.

I played Blooket first which was fun as it let me revise about last lesson's topics and was also very fun. My group made a model of a moon base using Tinkercad. We presented the model and answered questions about the moon base we had designed. I would want to add heaters to the moon base to heat it up as it is cold on the moon, and would also like to place add more things to the interior as the model of the moon base is mostly designed on the exterior. I could further improve the moon base by adding a place to catch asteroids. Overall, I liked this lesson and I am happy I attended this lesson.
21 May 2025:
I revised all of the topics by looking at a summary of all of the topics. After completing the summary, we played Kahoot which I thought was fun as it made me further review all of the topics and let us have fun. After that, we made a model of a base on mars with an observatory and more that was covered by a dome. I think spacebases built in mercury should have heaters or air-conditioners and the heaters will turn on when mercury is extremely cold to heat the spacebase up and the air-conditioners will turn on when mercury is extremely hot to cool the spacebases down. Overall, I liked this lesson and I am glad I attended this lesson.

I learnt about rockets and their parts through a playthrough of Kerbal Space Program. Kerbal Space Program is a rocket simulator game where you can design and launch rockets into space. Watching the playthrough was really interesting because it helped me understand how all the parts work together in a fun and visual way. After that, we played Blooket, which I thought was really fun. It allowed me to revise all the topics we had learnt, like the forces on a rocket and the stages of a launch, while also enjoying a friendly competition. Overall, both activities were very engaging and helped me learn a lot.

I learnt about the sun, the anatomy of a star and also how the gravity of the sun helps the solar system. When learning about the anatomy of a star, I learnt how every star has a corona, a chromosphere, a photosphere, a convective zone, a radiative zone and a core. I also learnt about nuclear fusion and thermal energy. I think the neutron star anatomy would have an atmosphere, a crust and a core. Red dwarf stars are smaller cooler stars and white dwarfs are the dense remnants of stars. After that, we had a Q&A where we could ask questions and clarify so we could learn even more.

I learnt about radio signals and radio waves. We formed groups and we were tasked to find a signal transmitter. The signal transmitter sends signals to the signal receivers which make sounds in the earbuds that are connected to the signal receivers and we use these signals to try and find the signal transmitter. I think fox hunting works by detecting the specific signal frequency that is being transmitted by the signal transmitter using the receiver. I think one of the applications of fox hunting in astronomy is that we can use signal receivers to receive signals transmitted from outer space.

I learnt about trigonometry and satellite science, especially about sine, cosine and tangent. I also learnt about the sine rule and cosine rule. I also learnt briefly about stars, their life cycle and how the colour of a star reflects how hot it is. Regarding the question "How do you think you can apply the sine and cosine rule in real life?", I can use the sine and cosine rule to measure large distances and celestial bodies in space. To measure the mass of a star, Kepler's Third Law and Newton's Law of Universal Gravitation is used to calculate the mass of a star. Overall, I personally think that today's lesson, although rushed, was interesting and I am glad I attended this lesson.
13 August 2025:
I learnt about stars, the life cycle of a star and how the colour of a star reflects how hot it is. I also learnt that the sun is a yellow dwarf. Another thing I also learnt is how red stars are the coolest and blue stars are the hottest. Regarding the question "Can stellar spectrometry be applied somewhere else?", I can use stellar spectrometry for planets, asteroids, moons and other celestial bodies. Overall, I think that today's lesson was interesting and I am glad I attended this lesson.

I learnt about radio waves and radio signals. We formed groups and we were tasked to find a signal transmitter. The signal transmitter sends signals to the signal receivers which make sounds in the earbuds that are connected to the signal receivers and we use these signals to try and find the signal transmitter. I also learnt about stars and the sun. I learnt that the sun has solar wind, solar flares, sunspots and Coronal Mass Ejections or CMEs. Solar wind is a stream of particles, solar flares are emissions of electromagnetic radiation, sunspots are holes in the sun and CMEs are bigger solar flares. Regarding the question "What surprised you the most about the
