Pok Fu Lam Village – Field Trip Reflection

Pok Fu Lam Village – Field Trip Reflection

On Oct 24, we went to Pok Fu Lam Village for a field trip. We went to Dragon’s Museum, different restaurants, a Dairy Farm Staff quarters. We saw  a hay silo, wall graffiti, etc. There were stray dogs along the way – the dogs were adorable. There were also lots of butterflies – i always had to duck because i’m scared of butterflies. 

We hiked up the mountain to see historical sights. The hike was steep and I slipped a couple of times but friends behind me pushed me up so that I don’t fall.

Along the way, we saw different conditions of how people live. Some have very poor living conditions and some were living off container vans. It does not seem comfortable at all. Some people who live in villages along the slopes of the mountain need to use common toilets because there are only 4 toilets for the entire village. 

Other things that we saw were cacti, a cow picture from a long time ago, schools and spider webs. We saw alleys that were very narrow. This hiking experience was more difficult than the one we did last year because of the steepness of the slope.

Up till now, I still wonder whether there are snakes or lizards around the area. It would’ve been scary. Hopefully there is none around the area. 

Disasters

Disasters

On May 12th, every class in grade 4 went to the library pit to learn about disasters. There was a police officer there named Mr. Graeme. He taught us many things about different disasters. Mainly natural disasters.

The things we learned about there was a landslide, typhoon and fires. The first thing we learned about was the typhoon. When there was a typhoon 7 or 8, they would put up the flag to the highest. If it was lower, the flag would go lower. The flag is to warn the people that are shipping stuff that people order that there is a typhoon coming.

Next, we learned about fires. We did not just learn about people setting stuff on fire or overcooking, we also learned about forest fires. There was one near my house and when I went outside I saw lots of smoke. People can also start forest fires by camping. If the fire is too hot, later it will cause the trees beside the fire pit to burn.

Lastly, we learned about Landslides. Landslides are when there are huge rocks falling from mountains. The rocks are really heavy, they can knock down buildings very easily. They can knock down half of an apartment!

I learned a lot about disasters and I am hoping to see another one of these presentations. 🙂

綠色天台生態系統

綠色天台生態系統

在學校十樓有一個很大很大的綠色天台。綠色天台上是一個美麗的地方。在綠色天台上有很多奇趣的植物、有水和石頭。植物可以給我們空氣。綠色天台的目的是讓學生不單可以知道怎麼保護我們的環境,更讓我們對美麗的綠色天台有更深的認識。

Kids Should Not Be Able To Eat In Class

Kids Should Not Be Able To Eat In Class

Kids shouldn’t be allowed to eat in class. I think kids should just wait until lunch or recess. It will distract kids and cause lots of trouble.

First of all, if they eat in class, there will be a lot of ants, bugs and flies around the class. Bugs and insects are usually attracted to food. Kids would then be coming home with mosquito bites. There will also be a lot of clapping. People will be distracted. There would also be several dead bugs on the floor.

Second of all, the classroom would be a mess! There would be food on the floor and on tables too. All the mess that we make, the janitors would have to clean it all up. Even papers will have food on it and people would think it’s disgusting.

Lastly, recess and lunch is only 1 hour and 30 minutes away. It’s like going on a hike for 1 hour and 30 minutes without food. You can just be patient and wait, and when it’s already lunch or recess, you can’t eat anymore cause you’re too full. You might even have a tummy ache.

In conclusion, I believe that kids should not be able to eat in class and should wait until lunch or recess. Kids will not focus and will create lots of problems. 🙂

Robotics Dance Challenge

Robotics Dance Challenge

On March, we started doing a robotics dance challenge. The way we do the robotics dance challenge is by getting 2 robots to dance. They both have to be synchronised. Our class was the first class to get the robots.

We have already finished doing the plan. Our dance looks a little bit too complicated. We have only done the start and we don’t have much time left. I thought my robot was a bit broken because at the start my partner’s robot was working when mine was not. Then mine was working and my partner’s was not.

For all of the sessions we’ve had robotics, I have been trying to fix my robot but it wasn’t working so I just changed it a little bit and it started working.

I think we did it because the teachers would think that it was fun. From doing the robotics dance challenge, I learned how to make the robot turn 360° .

What Was More Important This Week

What Was More Important This Week

2 Weeks ago, we continued doing the design project. I have wrote about this but I am now at a different stage and I thought that it was cool. I finished doing the design project. Now I am adding furniture.

I finished building my house. Now I get to decorate it. Before we went on minecraft and created our house, we had to finish a booklet. There were questions like: What is the total perimeter and area of your house and what is the perimeter, volume, and area of every room. After that, we needed to do 3 word problems. We could choose whether it was about perimeter or area.  I think we did it because it was interesting and we needed to know what perimeter, area and volume meant. From doing that, I learned volume and how to do word problems that have to do with perimeter and area.

I enjoyed learning about these.

Make a Map – Oceans

Make a Map – Oceans

On March 16th, I used BrainPop to create a mind map about oceans. I found out way more than the Land Biomes one I did. The video was called Underwater World. I chose this topic because I did not know much about what is in the oceans.

First, I found out that oceans are the largest ecosystems in the world. Over 70% of earth’s surface is covered with water, and all of the oceans connect so that animals can move between them. The Depths of oceans is so dark, no plants can grow, and the fish down there have light emitting abilities.

After that, I learned that there are a lot of different habitats underwater. There are sandy plains, mountains, coral reefs, deep canyons, and open water. Another one is called the Pelagic habitat. They are divided in 3 zones: Bathyal zone, Abyssal zone and Euphotic zone. The Bathyal zone have just a little bit of light. In the Abyssal zone, there is no sunlight and it can go down to 6,000m! The pressure there can turn you into a smooth paste, but there are still animals living in the Abyssal zone! The Euphotic zone is from the surface down to 100m, and they get enough sunlight that tiny plankton live there. They need just about every food chain in the ocean!

There is also a Benthic habitat. Scientists call it the ocean floor. It covers the coral reef to continental shelves to underwater mountains ranges to deep ocean trenches. One of the deepest trench in the world is the Marianas in the Pacifics. It’s over 11,000m deep and you can loose the world’s tallest inside of it!

Another habitat is the coral reef. The coral reef can look like a rock, but it is actually made of hard skeleton of small animals. The skeleton is from a coral polyp. Since the coral reef is close to the surface, sunlight penetrates the water.
All of those habitats support different types of sea life. If you combine all of those habitats together, there will be more than 21,000 species living in the water! I really enjoyed watching the video and creating the mind map. It was very fun.

Make A Map-Land Biomes

Make A Map-Land Biomes

On March 14th, we made a map about biomes. We used BrainPop to watch a video about it and created a mind map. On this mind map, I knew more than the other mind maps I’ve created.

Biomes are a system of plants, animals and land, and they all have similar ecosystems. Factors like temperature, rainfall and attitude all decide what plant and animal life a biome can support. I also learned that if you move an animal out of their biome, there is a high chance of them dying. For example: If you move a polar bear out to a Desert, it will most likely die because it’s too hot. The same happens with plants.

I learned about the different biomes. There are much more than I expected. One biome is a Rainforest, it can reach over 150 cm of rainfall each year, and they’re humid and hot. Another biome is a Temperate Forest. That is where Oak and Maple Trees grow, and the soil is very fertile. I learned about another biome called Taiga. They have cool summers and cold winters. There is also Grasslands or Savanna. There are NOT a lot of trees but lots of grassland. They have hot rainy seasons and cold dry seasons. The last one was the Desert, it’s hot during the day and cold during the night.

There was one biome I missed. It was the tundra. I couldn’t put them anywhere because there is no more space. I learned a lot from BrainPop, and enjoyed creating the mind map.

Mind-Map Ecosystems

Mind-Map Ecosystems

On March 9th, we began to start a new unit. I think our new unit is about ecosystems or just different types of systems. So we all went on BrainPop and watched a video about ecosystems, and then we created a mind-map about ecosystems. I found out a lot about them.

When I was watching the video, one of the ecosystems was a Desert. The Desert’s ecosystem is made up from living and nonliving animals that can interact with each other. Many times, ecosystems are categorized. From the amount of rainfalls and the sunlight they get, a Desert don’t get a lot of rain so there is almost no water.  They also have their own community of plants and animals that have adapted. Because of the hot and dry weather, Kangaroo rats sleep underground so it’s cooler (Cooler as in weather cooler). Plants and animals that live in the desert must be able to survive without any water.

Other than Desert ecosystems, there is also Water ecosystems. Some examples of water ecosystems are ponds, lakes, rivers and oceans. Communities can be separated into different populations. They are all made up by 1 organsim, and they all have their own habitat. There are many different types of habitats. One of them is the forest. Habitats are a little bit like biomes, but not really. Biomes are different places, habitats are like where they live.  

I enjoyed creating this mind-map and I am looking forward to create the next one.

Make A Map – Newton’s 3 Laws of Motion

Make A Map – Newton’s 3 Laws of Motion

On December 14th, we used BrainPOP again to make a mind map about Newton’s 3 laws of motion.

Newton’s 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.” So if something keeps moving and suddenly stops, it will still go forward until an unbalanced force acts on it. The unbalanced force is invisible so you can’t see it.

Newton’s second law is: “An object that has an unbalanced force acting on it will accelerate in the direction of that force.” So when you sit when you are on the sofa at home, 2 forces act on you. Gravity and an upward force pushing against gravity. If you slide down a slide, gravity wins because they are not cancelling each other out.

Newton’s third law is:”Forces always occur in equal and opposite pairs.” Which means if you push a door open, it comes back at you with an equal force. The door moved because friction is in between. The door is on hinges, which causes less friction.

I learned a lot about Newton’s 3 laws of motion. I enjoyed creating the mind map.
