## 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.

## Scratch Coding

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.

## Food Chain Mind-Map

This picture on the top is a mind map that I made in BrainPop and this mind map is about the food chains and also about the food web

Food chain is connected to the ecosystem because the food chain shows all the living things that eat each other. The Nourishment joins up to make the food chain and some of the animals depend on each other to survive. A example of a food chain may be like a plant plankton are eaten by the fish and and the fish is eaten by the bears near the river. If the shrimps goes out, the fish would go hungry and will eventually die, and if the population of the fish goes below way below the normal population, the bears would also get hungry. This can happen in the opposite way. If the bears go away, the the population of the fish would go higher than usual and the plankton will be eaten quicker.

There is another named the food web. The food web often combine to make food web many interconnected and overlapping chains. In a food web, there are three types of organisms. The Producers are plants and are all on the bottom of the food chain. They use photosynthesis to make their own food. Photosynthesis is the energy for the sun. There are three types of consumers in the world. The first one is Primary Consumers. Primary Consumers are sometimes named herbivores and they eat the producers like plants meaning the grass, flower, etc. There is also a secondary consumers and they are sometimes named Carnivores or Meat Eaters. They eat the primary consumers like deers, sheeps, cows, etc. Omnivores are animals that eat the Primary Consumers and the Secondary Consumers. Humans are also a Omnivores. Parasites are small insects that live on other animals and using the victim’s energy. For the decomposers are bacteria and fungi. It causes the mold but even better, it can break dead animals into reusable elements. It can also recycle the nutrients back to the food web.

## Tundra Mind-Map

This picture on the top is a mind-map of the tundra. I used BrainPop to make the mind-map and also used it to research what is tundra. I have one example, and many facts about the different types of tundra. There are three types of tundra on Earth. The Arctic tundra, Antarctic tundra and the Alpine tundra.

First, the Arctic tundra is a cold desert formed 10,000 years ago when it was the ice age. Glaciers covered most of the North America, and when the Earth got hotter by the sun, glaciers  backed away leaving the flattened tundra. It is on the top of North pole where there is Greenland, Alaska, Canada, Europe and Russia. There is no trees so it is a flat land. Tundra in Russian means treeless plain. This depends on where you are in the Arctic tundra,

Temperatures vary, but it is usually cold all the time. At winter, the average temperature is below zero and, it can go to minus 90s. In the summer, you will mostly not find the temperature above 50 degrees. When the temperature goes up, the snow melts and turns into water pools and the ground gets very spongy. With the water, these plants like bushes, grass and flowers grow. Under the spongy ground, it is permafrost that is cold and frozen all year around. But in these weathers, many kind of animal still make home.

The Antarctic tundra is the same thing as the Arctic tundra but instead of flowers and bushes, they grow Lichens, mosses and and algae.

The Alpine tundra is everywhere around, not like the Arctic and Antarctic tundra. You can find it on top of mountains above the tree line. In the Alpine tundra, the weather is very harsh, it has heavy snowfall and high, strong winds. But still in these conditions and the weather, animals and plants still survive.

The tundra is also connected the environment. Tracks made by transportation like cars, trucks and buses can be there for 30 years or more. These means every tundra is very fragile.

## 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.

## Things that I learnt this week (Feb/12 to Feb/17)

On the week, we did the project for visual arts. We are all making different products and we have to make a Eco Friendly Packaging for the product. My product is a Bamboo water bottle and I want to make a simple packaging for the product.

I chose to talk about this project because I think it was very educational for me and it teached me a lot of things. The teacher also talked about the colours that represent the meaning of ECO. We have to make the packaging for the product. We also have to make your company’s name and the logo for it. The teacher teached us about how these packaging for the product affects our world and the pollution.

## Mega Ice (field trip)

On Wednesday, Dec 15th we had a field trip and we went to Mega Box to do skating at Mega Ice. To be honest, I wasn’t good at skating, but I got better and better because I practiced a lot. Many people got hurt and I also got hurt on my ankle because the skates didn’t fit. But it was still very fun.

I also noticed that skating is connected to what we were learning, Forces and Motion. The ice was smooth so the ice had less friction. For example, the carpet would have more friction, meaning that you can’t slide on the carpet comparing to the ice rink. I should have talked more

about it in Newton’s Laws of Motion.

## 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.

## Tales of the Grade Fourth Nothing

This is a book that was named ‘Tales of a Fourth Grade Nothing’. Our class have been reading this book from the beginning of the school year. We finished the book today (Friday, November 18th 2016). I really loved the story.

This book’s ending is when Fudge came back from the hospital after when Fudge swallowed Peters turtle, he came back with many presents. Peter was very upset and left alone when he saw that Fudge just got all the present of his own. Fudge didn’t even saying sorry to Peter but when his dad came back from work, his dad gave Peter a present. He put a box and when he put his hand inside the box, he felt a fluffy thing. When he opened the box, he saw a dog. He was really excited because he really wanted a dog.

If I would be the author of the book, I will change the ending to …

Fudge came back from the hospital after when Fudge swallowed Peters turtle, he came back with many presents. Peter was very upset and left alone. Peter walked to Fudge and told him to say sorry about the turtle. Fudge didn’t respond but when he opened one of the present, there was a scary little doll staring at him. Fudge ran all over the place because he just doesn’t like dolls. Peter’s mom said quietly “Those presents were all fake”. Peter’s mom and Peter started laughing while Fudge was running all over the place like a wild lion.
