Health Blog Reflections
Some countries and cultures have special ceremonies when boys and girls hit puberty.
Do you know of any ‘coming of age’ or ‘rite of passage ceremony? If so, provide some details for your fellow blog readers. If not, research and provide the relevant details.
In Hinduism, the coming of age represents that a boy or a girl is old and mature enough to understand their responsibilities towards their family. There's also a sacred thread ceremony for boys when they hit puberty, called Upanayana, when they have a thread that goes around their shoulder to their hips. When girls hit puberty, they celebrate by having a ceremony called Ritushuddhi, where they wear a traditional dress called Sari.
Why do you think we don’t make a big ‘thing’ out of hitting puberty in this country?
I think that we don't make a big thing out of hitting puberty in this country because maybe we're all too busy, and we don't really care about those things. Also, maybe it's because in Singapore, we all have different religions and cultures, making it difficult to celebrate highly with all the different mixtures of celebrating.

Math Probability Reflections #3
1. Describe a situation in which you and a friend can use probability to make a decision. Can the probabilities of the outcomes be determined both experimentally and theoretically? Why or why not?
There are multiple ways in which a friend and I can use probability to make decisions. A few examples are flipping a coin, throwing a dice or spinning a spinner. For example, there are three people including me who wants to do different activities today. We can use a spinner with three equal portions for each of the activities we each want to do, and so then all of us have an equal chance of winning (1/3 chance). The probabilities of the outcomes can be determined both experimentally and theoretically. With the spinner, we can find the theoretical probability by using math. First, we find the total outcomes (3), and find the amount of the favorable outcome (1), and so then the theoretical probability is 1/3. We can find the experimental probability by actually spinning it as many times as we want and seeing our results.
2. Describe a situation in which it is difficult or impossible to find the theoretical probabilities of the outcomes.
A situation in which it is difficult or impossible to find the theoretical probabilities of the outcomes can be when the situation requires skill to win. A situation like this can involve with sports. For example, two new soccer teams are starting a match. Assuming we don't know the background results of each team, we don't know who has the higher probability of winning or losing, and so therefore it is difficult to find the theoretical probability.
4. Describe some of the strategies for determining the theoretical probabilities for situations in this Unit. Give an example of a situation for each of the strategies.
One of the strategies we can use to determine the theoretical probability is to use a fraction. We use this in simple situations, like throwing a six-sided dice and getting the number 2. You put the total number of outcomes on the denominator, which in this case is 6. Then on the numerator, we find the number of the favorable outcome, which is 1. So, the probability of getting number 2 on a dice would look like this:

A second strategy for finding the theoretical probability is drawing a tree diagram. For example, there are two bags. In one bag, there are four different colored blocks (one blue, yellow, pink, green). Then in the second bag, there are three different colored blocks (one black, red, purple). The theoretical probability in getting a blue block from the first bag then a purple block from the second is 1/12. I found this by drawing the tree diagram below:

Climbing Unit Reflection
What were your climbing strengths?
My climbing strengths was making sure safety comes first. I always try to check my harness and see if its safe, getting a teacher check, and also trying to watch my partner with my best intention while being a spotter. This was my first time doing a climbing unit, and it really teaches me about giving up and how to keep going. I realized I climbed and bouldered much better after a lot of practise.

What were your climbing weaknesses?
One of my climbing weakness that I think I have most problem with is knowing where to go and where to hang on. Usually, when I'm in the middle of climbing and I think that I have no where else to go, I don't have a plan and so I just try to get my hands and feet on any rock I can, but then I just trip or stumble and I fall back down.

Describe at least THREE checks required when putting on your climbing harness.
1. Make sure that your harness is above your hips and tightened, so that there's less chance of falling out of your harness during a climb.
2. Make sure that the harness around your thighs are tight enough that only one finger and get through.
3. Make sure that the carabiner's lock is facing the opposite of your stomach, so that it won't unlock when climbing.

What is your climbing goal for your next climbing unit?
I think that my next climbing goal for next time is to have a plan. I need to make sure and know where I'm going to go, so that I won't have to fall or trip down because then I would have a plan of where I think I should put my hands or feet next.
Always With The Questions!
One question that I have about the Douc Langur is, What does it actually look like close up? And how does it act when its active in the zoo? This is my question because while I was at the zoo, the Doucs weren't active, and all they did was rest. Also, I wasn't able to see them close up, because they were hiding far away from my view, and the lighting was dark around that area. I would really like to see it close up, and during its active feeding time next time.
If I could find out more things about them regardless of time, money and effort, I would really like to be able to get close to them and observe them clearly, how they grow and how they act with real field work observation.
