Today’s session was fun when we got to know new people who will be with us as we journey through the CCA. We could have tried to get to know each other through various methods other than games. I hope that we can have bonding sessions to prevent frequent conflicts.

Today was interactive, and quizzes were used to test our knowledge.
I learnt about the orbits in the solar system, the solar eclipse, and the lunar eclipse.
Overall, I liked this lesson and hope that lessons can be conducted like this.

Today consisted of a reminder of what we learnt last week, reminding us to always reflect on what we learnt when we have time. I heard my other CCA mates talk about what we had learnt, refreshing my memory before we made the slides. The Blooket helped remind me of what I had forgotten and made today's session fun. I would like subsequent sessions to remind us of what we learned the previous week before we started learning new things.

Scientists use light-years instead of km since the universe is too big, and measuring it with km is too impractical. Instead, they use light-years and convert them to meters. We learned about Kepler's Law to teach us the rules of the orbits. The simulations helped teach us Kepler's Law, allowing us to better understand how orbits work.

If I could travel back in time to an ancient civilisation, I would use astronomy to help the leaders navigate through lands when we go exploring, so that we can find the civilisation. Radiation will be used to find stars when the radiation detects the distance between the Earth and the stars. This can allow us to locate more stars than we can see. This can cause new discoveries in the astronomical world. This may also expand what we know as the observable universe.

I think Galileo had a greater influence on Astronomy. Galileo is known as the father of modern Astronomy and modern Physics. Galileo's use of the telescope led to groundbreaking astronomical observations, including the discovery of the four Galilean moons of Jupiter, the rings of Saturn, and the phases of Venus. Galileo also laid the foundations for Newton's laws, and without Galileo, it is possible that some of the knowledge we have about astronomy would not have existed.

I would add an energy plant to get electric energy to allow the base to be self-sustainable. This allows the base not to rely on the Earth, and it can just thrive alone. I would further improve the moon base with the information I learnt in the Universe Sandbox to try to make the base safer, and to try to create an artificial Albedo for the base. I think the base can also be improved to allow the base to have a fully sustainable source of oxygen.

I think space bases will be built on Mercury using many oxygen tanks, with a lot of domes for people to breathe oxygen and cool the base. Mercury will be very hot, and a lot of coolers will be needed to cool down the base. There will need to be a constant cycle of the coolers, since the heat will break them. Water may not be able to exist in the liquid state, so the coolers will help ensure the liquidity of the water. Minimal comfort will be present, but the study of Mercury will benefit humanity.

We learnt to use the Kerbal Space Program. I will go home, download it and try it out. But I enjoyed the session overall, and I hope to try to build a rocket that can at last get into orbit by the end of the month. The book quiz was an interesting way for us to refresh our memories on what we learnt in Term 2.

I think a neutron star's anatomy would be somewhat like a planet, with an atmosphere that prevents too much heat from being released. But, I think that the red and white dwarfs' anatomy has a relatively hot core that is slowly exhausting its nuclear fusion, while slowly losing heat, and has a dense body because of the number of hydrogen atoms inside.

I think fox hunting works from signals, with a similar concept to radio, where it sends out waves similar to Bluetooth. This could possibly allow for long-range communication or to navigate through a forest, to prevent ourselves from getting too far apart. Fox hunting, helping in navigation, also allows people to navigate, even with visual disabilities.

I think that I can use the sine and cosine in real life when we are chasing someone, and he makes a turn. We can use sine, cosine and tangent so that we can find the most effective route to catch him, and also when calculating rotations. The mass of a star is primarily measured by Kepler's Laws of planetary motion. By observing the orbital period and separation of stars in a binary system, they can calculate the total mass of the system. My brain has died from it.

Stellar spectroscopy can be used to analyse the light from stars to determine their physical and chemical properties. By breaking starlight into its constituent wavelengths (a spectrum), astronomers can identify the elements present, measure temperature, and assess other characteristics like velocity and rotation. I think that it could also be used to find out the possible distance to a star, without having to leave the Earth. Also, please save my brain so that it is not fried every week. But it is kinda fun. I kinda hope that lessons will not be so hard.

I think that this session was quite interactive and interesting, and we definitely gained a better understanding of how stars are formed. However, I was not able to fully understand much because the slides were too light, and I was struggling to see them, and I could not hear the teachings. However, the session was fun, with the Blooket, and it definitely was not as content-heavy, so my brain is definitely alive.

What surprised me the most about the Sun was the Solar Storms, which could easily change our livelihoods, with there being no access to electricity. I think that with people being so reliant on electricity, this could make some people go insane and struggle to find other means of entertainment. However, today's session was very fun. The fox hunting, otherwise known as transmitter hunting, was interactive, but it was very tiring. I think that trying to memorise all there is about the Sun will cause my brain to fail, so can we have less Sun knowledge, please?
