Dinner! Aussie-styled grilled food

Hello! We had lots of fun today. Firstly, we had a modelling forum today and we used our data collected from yesterday to prepare powerpoint slides. Then we had to present them in front of the other groups.

Tanya:
Today we had a modelling forum and we had already been split into different groups/classes before hand. Hence, we got to mingle with students from other schools and we also had students from the ABPC.

Firstly, we used the data collected from Movie World yesterday to prepare powerpoint slides. We had to come up with a problem involving our ride chosen. Our group chose to work on the acceleration rate and G-force involved in our ride. We also researched on human body stats and on the G-forces. Through this, i learnt about the new chapter of velocity and acceleration.

Secondly, we worked together in our groups to make good presentations on our data collected. For example, we learnt about velocity, acceleration rate and speed. We made many graphs using the data. For our group, we used the data collected from the ride we went on which is Batwing Space Shot. It goes vertically upwards and downwards pretty fast. The data collected from the calculators were then put into our slides.

And we then finally presented our findings to the other groups. We also had a maths quiz where we split into groups again. We had to work together to answer many maths questions. It was thrilling(:

Then we had a lecture by a 17-year old mathematician after the modelling forum. He gave us information about the human brain, newton's laws and engineering. Finally we had a western BBQ dinner which was very delicious(:

Qianyu:)
Today was very exciting! (: We were discussing in our groups, about the data we collected at Movieworld. For the powerpoint slides, we collated the data focusing on the ride Lethal Weapon, calculating the speed/acceleration of the coaster.

My group members included See Ying from NAS as well as Yuan An from RGS. I felt that teamwork was very important in collating the powerpoint slides, like distributing the tasks. It was a unique experience for me and enabled me to look at situations in another perspective (coming up with questions, limitations, assumptions etc). During the 5-minute presentation to share our data/thoughts with the other students, I learnt that confidence and clarity were also very important because we had to achieve our best;)

The Math trivia event came next, where we grouped into different 'animals', I was in 'Lion'. It was very thrilling and fun, working with others from schools such as TPJC and A.B Paterson, we made many new friends and we co-operated working out the word problems.

In conclusion, I really enjoyed today's activities and learnt much from the programmes. It was both exciting and educational :D

Sherilyn :
Today was quite interesting. In the morning, when we were in our groups in the class, we chatted about yesterday, when we were in Movie World. We were laughing about the fun rides and I felt that we were more bonded.

Just before lunch and after lunch, we worked on the powerpoint and the data that we collected yesterday. we had to use the graphic calculator while analysing the graphs. I learnt that we apply Math in many things.

We worked together within the groups and prepared a powerpoint. After all the preparing, we had to present to two classes. It was a good experience as we had to present to people from the A.B.Paterson  and to other students from Singapore. We listened to other presentations done by other groups and learnt that we had lots to improve on.

After that, we had an activity called the Math Trivia. We were grouped into different groups and had to compete with other groups against time to do a Math quiz. I found they grouped us very interestingly with animal names. I was in the group called ' Kangaroo'. We had lots of fun answering the questions and it was very trilling.

Lastly, before dinner, we had a talk by a 17 year old mathematician.

Looking forward to the Mathematics Challenge and Dream World :D

Roshini-
I found that today's programme was very interesting as we could apply mathematics to real life situations. I learnt about several new concepts such as velocity and acceleration. As I grasped the concepts quickly, I could help my teammates in pin-pointing tiny details in our graphs which we had to change. Moreover, I could also relate the concepts to real-life applications. Our question was about the highest accelerations and we can use this information when designing rides to prevent injuries and to warn about potential dangers. I had fun working with different people. We have to adapt quickly to new situations. I felt very proud of my group's presentation as we had to overcome several problems such as plotting a wrong graph.

The Maths trivia quiz was extremely fun as we got to solve a lot of questions while we enjoyed ourselves at the same time. I realised that Maths also had fun elements and is not boring.

We also had lectures by guest lecturers and it was very informative. I am looking forward to the Modelling Challenge to get to know new people. :D

Priscilla :
I have learnt to think critically about real life problems and making it into a maths question. At first, we did our task based on Lethal Weapon and the question we posed was on the acceleration of the ride. However, we realized that we were unable to find out the results as the data collector recorded data every 0.01 seconds and the ride lasted for approximately 50 seconds and hence it would have taken very long for us to record the data. We tried to take a few values to draw the graph but it was not accurate. Thus, we changed our question to finding out the height of the tower of Batwing Space Shot. My group found the height of the Batwing Space Shot by Pythagoras Theorem. We used the Clinometer app on the iPhone to measure the distance from the tower, afterwhich we have to add the height of the person holding the clinometer as the angle from the eye and the angle from the floor is different. We got to learnt from one another as all of us have different ideas and perspectives.

We managed to work together as a team and get our results which were quite accurate. We split our work evenly and managed to finish our presentation in time. After the presentation, we had a math trivia event where we were split up into different groups. We get to solve questions of different difficulties together as a team. It was quite enjoyable as it feels satisfying to be able to solve the questions.

We had a talk by a 17 years old student who was giving us a talk on brainwaves. It was inspiring as it was rare to see a 17 years old student to be doing his degree. After the talk, we had a wonderful dinner and dessert baked by the students in the college. (:
