I learnt that the moons actually has eight phases and there are three types of lunar eclipses and four types of solar eclipses. What I learnt was interesting, though I did not quite fully understand it. I like the use of different simulations to teach us more about the solar system, although I feel like there wasn't enough time for me to take in everything. Overall, I think this lesson was pretty good and I would like to see more of them.

Today, I started off with doing a blooket quiz to recap so that I could jog my memory a little bit. After we did that activity, our group was instructed to create a presentation within 45 minutes about what we learnt last week and we had to go first because my groupmate got last in the blooket quiz. Overall, I think this lesson was still fun and I would like to learn more in future lessons.

Today, I learnt that the Sun is 93 billion light years away from the Sun. In order for something to orbit, it needs to be a moving object and that its orbit is elliptical but never fully circular. Astronomy is the study of space and scientists use satellites to study space. Scientists also use light years instead of kilometres. I learnt about orbits, planets, as well as Kepler's 3 laws and that a supernova is an explosion when a star dies. Overall, I think this lesson helped me learnt a lot of new things and I would like to see more of them in the future.

Today, I learnt about radiation and spectras and other cool stuff. If I could travel back in time and join an ancient civilisation, I would convince the leaders to use astronomy for planning and decision-making by telling them that they most likely did not have the advanced technology, so they could maybe plan by observing the stars to strategise. Radiation is important for finding stars in the Milky Way because they can penetrate the dust and gas that obscure the visible light emitted by stars.

Today, I learnt about telescopes. I learnt that there are different types of telescopes, the main one being the reflector telescope. I was also taught

Today, we did a debate about which planet NASA should spend money on researching and colonising. I learnt a lot of new things from each of the group's sharings, like what planets they chose and why. I learnt that stars that did not move were called fixed stars, while those that did were called wandering stars.
Question: Who do you think had the greater influence in Astronomy: Galileo or Newton?
I think that Newton had the greater influence. Newton's three laws of motion provided an understanding of how objects move and interact. His law of universal gravitation also explained the force that causes objects to attract each other, including the motion of planets around the Sun.

Today, we started by doing a booklet quiz to recap on the things we learnt about telescopes and i got 2nd place. After that, we were grouped into the same group of 4 as last lesson. We were then instructed to build a moon base in 30 minutes in Tinkercad and my group went first again two lessons in a row.
Reflection:
I would want to add more research items and some observatories.
i would add different power plants to generate more electricity.

Today, we had a summary of everything we learnt in Term 2. After a lot of chaos, we then had a Kahoot quiz to test our knowledge so that we would be able to take in most of what we learnt during CCA. We then built a Mars base on Tinkercad and my team went first three times in a row.
Exit Question:
I would build it underground to shield it from the extreme heat.

Today, we began by listening to 2 groups who went overseas to participate in the TAC and got gold and silver awards, present their work to us and their experiences. After that, we learnt about how to use Kerbal space programme to build a rocket and the parts required to build a good rocket. Then, we played blooket to recap on what we did.

Today, we learnt about the anatomy of a star. I learnt that stars (excluding neutron stars) are comprised of many different layers, like the Corona, Convective Zone and the Core. I also learnt about what happens in each of the different layers. I was also taught a bit about nuclear fusion.
Exit Question(s)
I think that neutron stars would be about the same as normal stars, but a little different.
I think that a red and white dwarf star would have a few layers absent.

Today, instead of having another lecture or lesson, we did a huge hands-on activity and it was called fox hunting. All of us were split into five groups and were each given two radio signal receivers. We were then instructed to find a radio transmitter hidden somewhere in the school. This was the most fun session so far. Although it was just walking around, it was like a treasure hunt trying to find it. My group also managed to find it in the final round.
Exit Questions:
I think fox hunting works by using radio signal receivers to locate a hidden transmitter.
I think they could be used to detect radio signals from outer space and could also be used to maybe have communication with people there.

Today, we were taught 2 lessons about math and a short presentation about stars in between. In the first math lesson, we were taught about the Pythagorean Theorem and learned some trigonometry and about tangents. The short presentation included the Hertzsprung-Russell Chart and we were taught COS and SIN after.
Exit question
you can use in science and math lessons and engineering
Kepler's third law and Newton's law of gravity.

Today, we learnt about the birth of a star in the first lesson. We also played a game of blooket in between to recap what we learnt last lesson. The birth of a star has five stages, starting with a nebula and ending with a star. In the second lesson, we learnt about how to read wavelengths. We further improved our understanding of the doppler effect and learnt about the different colour of stars.
Today, I leant about adolescence and the birth and death of stars, with a short recap about the HR diagram. Small stars become red giants and then white dwarves. Big stars become supergiants and neutron stars. After that, we played a blooket to recap some stuff we learnt in the previous lesson.
