## Reflection of the week (Mon, May Ist/Fri, May 2nd)

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.

## Performing arts Light paintings

In PA (performing arts), We are doing dance unit which we make our own dance with a group. With the dance, we are going to make a light painting. A light painting is made in a dark room and for this to work out, we need light to make the painting (Glow Sticks) and stick them onto your body. We need to take photographs and this will make the light painting. We will need a app to make the light painting. One app that you can also use is Light Bomber. At our school, we are focusing on patterns and shapes that we can make in the light painting.

We had a process to make our dance. First, we learnt how to draw the people in the drawing. Our teacher told us not to draw stick mans and not to draw too realistic that will take a hour to draw. She teached us a simple way to draw people. It was easier to see and it was really neat when she showed us. Using what we learnt in the first part, we used a storyboard to plan our ideas and bring them together. In the storyboard, we drew how the dance is shown and the important details can be written on the bottom of the drawing. When our group finished the storyboard, it was very neat and everyone could have understand it. When we finished the storyboard, we rehearsed with our group. We did it many times and as we practiced, we got better and better. Next class, we will be able to make the light painting using a app. I am very excited to see what our painting will look like when we finished.

## What we did this week (Wed 18th-Fri 21th)

This week in Visual art, we learnt about a famous painter named Matisse. He started painting when he was very young, but when he got older, he got cancer, meaning he couldn’t paint anymore, but he started making cutouts of pictures. He cut paper and he taped it on his canvas and also on walls of his house. We did this activity because to learn about famous painters and how the painters drew and the type of art he drew. I chose to write about this topic because it was very educational to me and it is fun to learn about other painters. First we watched a video on Youtube about his paintings and his cutouts and then we tried to use his idea and make cutouts of beautiful places or some students made random cutouts. It was very fun to make the cutouts and I felt very creative and enthusiastic about this learning of Matisse.

## Land Biome Mind-Map

The picture on the top is a Mind-Map is about Biome. Red boxes is for Important and main idea. The blue box is the examples and other things are facts about it.

Biome is and interdependent system of plants, animal and land. It is also a large region with similar ecosystems. Temperature, rainfall and altitude all decide what type of plant and animal life a biome can support. A place called Utah consists mainly of the desert biome. These plants, animal and land each evolved to become specially adapted to their environment. If you move an animal or a plant out of it’s biome, it might not survive. There are countless species of plants and animal living on Earth.

All of these species live in different biomes. Subartic Taiga has cool summers and cold winters. Evergreen trees grow and the soil is rocky. At Tundra, it is very cold at all time. Soil is frozen all year round, so not much can grow besides lichen and moss. Temperate Forests are found in areas in mid-latitude. It has a moderate rain and the four season. Oak and maple trees grow here, and the soil is very fertile. Deserts get less than 10 centimeter of rain each year. It is very hot all day and cold at night. Grassland or savannas are found in areas like Central Africa. It has a hot rainy season and a cold dry season. Rainforests are in areas along the equator. Over 150 centimeters of rainfall each year. It is humid and hot like Hong Kong.

Different biomes been around thousands of years but change time to time. For example, Icy glaciers once covered most of North America. Before, It was covered by a shallow sea. It takes millions of years and the plant and animal have time to adapt they need to adapt. But because of the human activity, it has changed everything. Humans can change a biome overnight by cutting down trees, throwing up buildings and polluting the water. Without the proper habitat to support, plants and animals can become extinct. If people knew how fast forests can become deserts, they might think twice before messing with our more fragile environment.

Last week, our class went down to the library to look at the Grade 10 exhibition. The grade 10 exhibition is a personal project that the grade 10’s made.

We saw some creative ideas and some people used technology like the computer and coded video games. I remember one of the student used a bicycle and made a machine to make electricity so we can charge the computer. It was really hard than I thought it would be. I also remember somebody using Sketchup to design the house and made a small sculpture out of it.
I think if these creative ideas be able to spread around the world, It might help the future a better place to live.

This picture on the top is our poster. The one on the left used colour and words that pops out. One of the sentence is bold because it’s the most important thing that they want to tell to people who buy their products. It is very simple so it’s very easy for people to see. It also tells us more info(name of the product). You can tell that it is new because it says “Get your groove on. In four new colours.”

On the right one, it has the logo on the top so it tells what company made this product. The person on the advertisement is happy, so it tells us if you buy the product, you can be happy and excited. The background also stands out because the colour is is green. It is also big so it is easier for people to see. It also says the description of the iPod on the bottom. The iPod also stands out because the it’s white.

Our group thought that the left advertisement is better because it’s more neat. It is also clear to for other people to understand the product they’re trying to sell. There is more info than the right one. There is more colour so everything stands out. Our group thought the right one is too plane because they didn’t write anything. It used less colour than the left advertisement. We also agreed that the words on the bottom is too small.

## Newton’s Laws of Motion Mind Map

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.

## The Sailboat Maker Design Challenge

On the December 1st, we did a challenge to make a boat and make it move across the basin. The boat needed to hold one marble. The boat also had to move by the wind. I was put into a group of three. We only had 15 minutes to make the boat. We used paper and cut them into pieces and we also used cardboard, tape and a stapler.

The first thing that went well is that it moved really quickly. But really, I think it didn’t really go well. Our group succeeded the challenge but some parts it didn’t go well. Firstly, the sail was tilted because the tape that held the sail wasn’t strong enough to hold the big large sail. Secondly, the boat almost sank because the water got into the cardboard on the bottom of the boat (as you can see from the picture). I found it difficult because there was only 15 minutes to create the boat. It was also hard because it also took time to decide what the design will be. I can improve on to our group’s boat by making the base of the boat bigger so the sail can be stable. We should have use the plastic bag to cover the cardboard. For this activity, I enjoyed looking at other group’s boats because it was really different from our design.

## Buoyancy

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.

## Learning Buddies

Last week on Friday (Nov 25, 2016), we had learning buddies. One person have one partner and you do things together. Last week, the first grade started a unit about Exploration. So the activity we did was exploring through the school. Students in first grade had one destination that they wanted to go to. My partner wanted to go to the 14th floor ( the top floor ). Other students chose to go to the Green Roof or other places. My partner also had to take pictures when going to the 14th floor like the real explores. They took pictures of the staircase and the sign on the staircase that says”14th floor”. My partner and I went to our class and also took some pictures there. They were really impressed with the computers because they didn’t have their own computers. They only had their own I-Pad. I think my partner was very excited for this activity because it is their choice to go anywhere around the school.
