Today's lesson was boring, aside from the fact that I learnt more about my CCAmates. I hope that future CCA lessons will not be as dull. I think it could be more interesting to have Astro-related activities to get to know each other.

Today's lesson was entertaining and not dull like the previous lesson! We learned about magnetars and stars with HUMUNGOUS magnetic fields and ran many simulations. The next part included much information about the moon. The weather is often extreme on our planet, such as the moon's high latitude. After all this, we had a quiz to test our knowledge. This not only helped me to remember all these but also made the lesson way more enjoyable. It was a pleasant experience and was flawless.

Today's lesson, we made slides about our past lesson. This helped us to remember everything that we had previously learnt. Moreover, we also had another Blooket game in which we revised our knowledge from the last lesson. Although today was slightly dull, all the astronomical knowledge was stuck firmly in my mind. I hope there will be regular lessons (like once a month) like this so that we will never forget what we learn.

Today, we learned about the universe's size, gravity, orbits, Kepler's 3 Laws of Planetary Motion, and more! I liked today's lesson as it was new information for me. I found the topic of how planets move in elliptical orbits particularly fascinating, and understanding gravity's role in keeping everything in place gave me a whole new perspective on space. After that, we memorised everything with one round of Blooket, which made studying feel more like a game than work. Today's lesson was the best so far. I liked the plan and the slides. I hope lessons are like these from now on. The explanations were clear, the visuals helped a lot, and the interactive part made it stick. Exploring something so vast and mysterious felt exciting, and it left me wanting to learn even more about space.

Today, we learned about Radiation and Chroma. There are three types of radiation: Alpha, Beta and Gamma. Alpha particles are an ionised helium atom. Beta particles are decayed protons or neutrons. Decayed neutrons are ß+particles, which means neutrons are turned into protons, positrons and neutrinos. In contrast, a ß-particle is a proton that turns into a neutron, an electron and an antineutrino. We learned about wavelengths, too. We knew that the shorter the oscillation, the higher the wavelength. We learned even more that I could not write. This is good. Very good.

I learnt about telescopes today, namely the mechanics and different types of telescopes and lenses. Initially, it wasn’t easy to understand, and the presenters could have slowed down. Though crowd management could be improved, good examples and hands-on activities were used. Overall, I feel glad I attended this lesson. I would like to see more of these lessons.
Answers to questions :
Hans Lippenshey and Galileo Galilei
Lenses and Tripod. Lenses refract light to magnify distant celestial bodies, and Tripods hold a telescope up.
I learned how to set up a telescope, how to use the telescope and how to operate a telescope. This will help me to be able to see distant objects in space at stargazing events.

I learnt about the history of astronomy and had a debate session on which planet to invest in for future colonisation. It was interesting to learn about debating skills. It was a fun and engaging experience, and I hope future lessons will be as engaging. There could be more quizzes to help us remember the history of astronomy, though
Newton. He invented gravity, which fundamentally enabled us to understand orbits and more. It became an essential part of astronomy and was used to discover many other things.

I learnt how to build a moon base and had fun watching Jupiter get pulverised by a magnetar. I also learnt the 4 factors that can affect a planet's habitable zone. They are:
The atmosphere. (Example Greenhouse Gases, and also the thickness of the atmosphere [Thickness of atmosphere ↓ = heat needed ↑)
The luminosity of the star
The type of star (eg white dwarf, magnetar)
The albedo of the planet
I can improve the moon base by adding more detail, and adding research labs and more.

I basically revised everything I learnt in Term 2.
Mercury is really hot, so it would be built by using rubber to make a super thick wall and use cold water circulating within the wall to cool the dome down and keep the temperature in the dome relatively cool. This is because both rubber and water are bad conductors of heat, making it hard for the temperature in the dome to rise.

We did fox-hunting today.
It was very tiring as we ran around the school.
There can be improvements, such as saying when the thing we are tracking is moving or if it is stationary.
Overall, it was a decent experience.
Fox hunting works by using an object that emits radio waves and uses a radio receiver to receive the signals and track the object down.
We can use radio receivers to tell where galaxies are, as all of them emit radio waves from celestial objects or phenomena within them. We can also track things like black holes merging, quasars and more.

We did trigonometry and phythoragas' theorem. I enjoyed tdy lesson and no improvements needed
sin a/A=sin b/B=sin c/C
c^2=a^2+b^2-2abCos c
Cos c=(a^2+b^2-c^2)/2ab
Tan= opp/adjacent
For math tests and O Levels, Maths and Astro Olympiad and research
By observing gravitational pull on other objects, preferably binary star systems

Stars and how they appear:
Nebulae
Compressed Nebulae
Protostars
Nuclear Fusion
Star
Lesson = fun
Suggestions = nothing, good enough
Exit Pass 1: Spectroscopy has diverse applications including astronomical analysis of distant galaxies, medical diagnostics for disease detection and drug monitoring, material science research for characterizing and improving materials like semiconductors and batteries, environmental monitoring to detect pollutants and dissolved oxygen, food quality control for identifying contaminants, forensic analysis to identify unknown substances, and archaeology for non-destructive material characterization

More about stars. Also, universe sandbox. The last part was fun but I got no sweets from writing notes ;(.
The lesson was interesting and I learnt quite a bit.
We also watch Advaith use the universe sandbox. The excos also tried to make people take notes by handing out candies as prizes for booklet and taking notes. In the last part, we played a game of Black Gold Quest, which was chaotic as many people kept swapping.
Overall 5/10 stars no drama.

We had another fox hunting today, which wasn't that fun. However, after that, we were taught about the sun, which was a good save. The fox hunting wasn't that fun, but the presentation with the cool videos about the sun made up for it.
I never thought about how dangerous solar storms can be, and was also shocked that solar storms were that cool and could affect electric supplies.
