What is different from a theoretical probability to an experimental probability?
Theoretical probability is where people use math and logic to find the answer, while experimental probability is a probability result that comes out of an experiment. Theoretical probability and experimental probability may be different at times. For example, if we were to be doing an experiment for probability using one red and other two green, the theoretical probability would be a ⅓ chance of getting a red apple in which for a green apple would be a ⅔ chance. For the experimental probability, it can be different from theoretical probability because when experimenting, one can happen to get the red apple 10 or 11 times in a row or get a result that differs a lot from the theoretical probability.

During my class for probability, I think that probability was easier than I thought it would be, though being able to learn more deeply on the words for the probability was a great way to catch up on my mathematical vocabulary too. Something that I found which was difficult was when I was to read a sentence and see if that was possible or not because there were some parts which were hard to understand if one thing would be possible or not. Something that I gained from the probability class that I had was the challenges that of the possibility choosing problem and that challenge taught me to understand a little more about the possibility for many things in my daily life. This probability that I have learned has led me to understand more of being independent as for the possibilities that I thought was possible or not. If I were to take this class again, I would try to use what I have learned in my first class and try to challenge myself with parts that I was unfamiliar of and to get better in finding the probability of events or things.
This is our first week in 2018!! This week was a very fun week. This week, we put legs on our robots. We put the legs on our robots because we will need it for our fashion show. With our class, we will have our robots in our fashion show and we are going to make a costume for our robots. BIG shout out to the Artists and Residence for helping us to make our clothes for the fashion show.
This week, we did a lot of things. For example, we learnt about Multiplying and Dividing Decimal Numbers and we also learnt about Circumstances and Less Privileged People. I think the very important thing that we did is the poster that I worked on. I made a poster about Myself and Less Privileged People. I used Compare and Contrast to describe the similarities and difference about myself and Less Privileged People. For the similarities, I wrote that…
We all have a house
Some people are free
Some people and places have a kind of transportation
Some communities have events
There are teachers
We all are able to afford some food
For the differences…..
What their houses are made out of
The clothes they wear
They don’t have common things that we have(pen, paper)
There are no classroom(no enough money)
A way people including myself to help the less privileged people is by…
Give money to charities
Volunteering to help people in need
Work for a charity company
After that I finished that, I drew pictures and put a picture that I found on the internet
In Digital Ambassadors, we are working on really cool things. Will first, Digital Ambassadors(DA) is a group of people who have been picked by the teacher and will work and learn more about digital things. I am one of the student who was picked. We are using a thing called Micro-Bit (Picture on top). We use the computer and code the things that we want the Micro-Bit to do. And we have to upload it to the Micro-Bit. We coded games, like rock paper scissors and other game. This is the link to the website that we use to code for Micro-Bit.
On Tuesday May 16th, We had our coding class. In coding class, we adding on to what we are doing on Challenge 2. In Challenge 2, we have to make a code that draws words. In my project, I have finished drawing a A, B, C, D, and O (This is the Link to the project). I am really looking forward to finishing my project for Challenge 2. At school, We are learning about the coordinates and other things that you might need for the code. It was really easy for me because I have done the same thing in a place where you learn how to code. Instead of making more words, I have been helping others to make their code better and also solve problems in their code. If I have more time, I would really like to make my codes better and make the words look realistic.
Overall, I think I have been helping others and our class has been cooperating and they are also curious about for the code.
This week was a short week because there was Buddha’s day and Labour’s day, but we did many things.
The first thing that I want to show you is coding. On the last post, I think I posted a blog post of the tessellation. I really like coding, because I go to First coding to learn Java. We are using Scratch to code things. The picture on top is my tessellation. We are doing this because it is helping our mathematics and it is fun to use coding to make things. I chose to write about this because I like to do coding. I still knew a lot of Scratch coding, but I still learnt a lot because we don’t usually use so much math in First code.
The second thing is in Visual Arts. We learnt about Leonardo Da Vinci. We did it because we are learning about artist. We learnt about the mysteries of Mona Lisa. We also learnt he was an inventor too. I chose to write about this because I like to learn about the paintings that artists and what artist draw. I also like about the history of things, like paintings and invention.
Overall I had a great week by learning about these things
We used scratch to make a tessellation. The tessellation can be made forever but if it touches the edge, it ruins the tessellation. On the first time I just made a shape but I tried and tried and thinked and actually, I made the tessellation. The hardest part was to calculate the degrees and the steps to calculate. I used the clues that Ms Fung told us. I learnt about the codes that makes the code. Because I finished the challenge. I am trying to make arrangements to make it much more creative and much more fun.
This Mind Map on the top is all about the Newton’s 3 Laws of Motion.
The first law is an object in motion will stay in motion, and an object at rest will stay at rest unless an unbalanced force acts on it. For example, if you are driving a car, when it stops suddenly, the things on the car will fall off. That is when the unbalanced force acts. Friction is a resistance caused by any two objects in contact and it always act in the opposite direction of that force.
The second law is when an object that has an unbalanced force acting on it will accelerate in the direction of that force. Every time, Gravity pulls the mass toward the centre of the Earth. The upward normal force of the ground is pushing up against Gravity(two forces cancel out) so that means that you will not move. When you go on a slide, Gravity wins because of the angle. Gravity wins and you accelerate. In this example, There was net force always acting and making it accelerate is a combination of the normal force and the Gravity.
The third law is force always occur in equal and opposite pairs. If you push a door, it pushes right back at in with equal force. The door was on the one that moved because friction between a person’s feet and the normal force and the gravity.
This picture on the mind-map is all about the Buoyant force, Gravity, Fluids, Volume and Displacement.
A Buoyant force is an upward push that fluids give to any object you toss in. The Buoyant force don’t resist force the way solids do. It is because the gravity pushes it back when you hit a solid block. It doesn’t seem that when you put your hands inside a liquid (water), the force is reacting to your hand. But in reality, fluids do react. For example, When you dunk a beach ball into a pool, it takes a lot of effort. But when you let it go, it’s lifted by the buoyant force. Fluids are any substance that flows or that have on fixed shape. For example, like water and other liquids. Also, when you put a solid block in a pool, it slowly sinks to the bottom of the pool. When you weigh an object that is in the pool, it is as twice as light on the ground.
When you put something in a pool, some water moved to make room for the object. It’s easier to see in a cup of water. For example, if you put a cube of ice into the water, the water rises to make space for the ice cube to be inside the water. That is called Displacement. Displacement means that the displaced water and the object take up the same amount of space. Meaning that the Volume is exactly equal. A volume is a the amount of space that an object or a substance fills; the amount of space that a container has. The thing is that if an object weighs 125 lbs (on land) – 70 lbs (in water) = 55 lbs (the water that is displaced). In the past, a famous person named Archimedes’ Principle discovered that the buoyant force is equal to the weight of water an object displaces.
This picture on the top is a strategy for addition. I normally use the normal way when you put the two numbers vertically. This picture on the top is a strategy when you break up the numbers into tens place and the ones place.
Now, you got the answer for the tens place and the ones place. Then you add the tens place and the ones place answers together. Then the answer will come out ( if your addition is correct ).
Some people maybe think that this strategy is useful, but some people might think that the vertical way is easier than this strategy.
