Matariki

Hi guys, so in Wananga, we were assigned to do a poster talking about Matariki. We had to include 4 to 6 facts about Matariki and a picture showing the Matariki stars in the sky. Here is my poster hope you enjoy it. Bye. 

 

Government & Politics

Hey, guys today I will be sharing what I have been doing in social studies with Mr Carter. We are learning about the polities and the government. We had to pick a world leader for example Jacinda Ardern or Nelson Mandela two very powerful to research and make a biography, timeline and a political poster about them. I chose Rosa Parks because I found her very interesting and she was a huge movement in civil rights. We are working on making our own political parties at school this term so be prepared for a lot of political stuff. For these presentations, I use piktochart because I very rarely use websites to present my work. 

What is a leader?

Google - A person who leads or commands a group, organization, or country. 

My Opinion - I think a leader is understanding and listening to your people when making decisions. A leader should be humble, understanding, confident and have integrity. What is your opinion on being a good leader?

Timeline & Her Story 

I have made a timeline about Rosa Park's life and how she protested for her rights. This timeline starts when she is born in 1913 to when she passed away in 2005. Fun fact, she was nineteen years old when she got married. 

Political Poster - VOTE FOR ROSA PARKS

Imagine if Rosa Parks decided to run for president of the United States of America. This would be her Political Poster to tell people to vote for her. I went for the same themes as my timeline and biography. Personally, I think Rosa Parks is an important part of our history and shows courage when refusing to give her seat. This has changed the history of America by giving them freedom.

Seven Types Of Government 

After doing that task we were assigned another task which was talking about the seven types of governments. Our teacher gave us seven more to learn and make a presentation to show our learning. They are Democracy, Dictatorship, Monarchy, Communism, Totalitarianism, Oligarchy and Anarchy. We had to talk about what they are, how they work, what countries are under these governments, pros and cons, a person who had to lead the country, for example, Democratic President Barack Obama, and then make a map showing that type of governments around the country world. I did my presentation on a Canva and used My Maps to create the types of government. We are learning about governments because soon we will be forming our own political parties with a leader and will be trying to get people to vote for us.

Diffusion of Potassium Permanganate - Science

Hi, guys today I will be sharing what I have been doing in science. We did another experiment and learnt about diffusion. Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Diffusion happens in liquids and gases because their particles move randomly from place to place. Diffusion is an important process for living things; it is how substances move in and out of cells. 

Question/Aim: Does temperature speed up or slow down Diffusion?

Equipment: Tweezers, Petri Dish, KMnO4 or Potassium, Hot water, Coldwater

Method: Fill one petri dish with cold water and one with hot water. Then put the crystals in each and see the magic.  

Result/Observation: When we put the purple crystal in the warm water it was twice the size of when we put the crystal in the cold water. 

Conclusion: The particles in Hot water are moving faster.  

Imploding Can

Hi, guys today I will be sharing what we were doing in science. It is about learning about air pressure and particles. This was a very interesting experiment because instead of seeing something explode we saw something implode. 

Implode meaning collapse or cause to collapse violently inwards.

Equipment/Method:

- Tripod 

- Bunsen Burner

- Heat Mat

-  Gauze Mat 

-  Soda Can 

- Scissor Tongs 

Instruction:

1. Step one is to fill the soda can with 10 to 15 ml of water. 

2. The second step is to set up your experiment. Using this equipment tripod, bunsen burner, heat mat, gauze mat and a soda can. So we are heating the soda can. Set up your bunsen burner and put the soda with the water on top. 

3. Step three is to use the scissor tongs to lift the ho soda can and put it in water.  

Result:

So at the end of the experiment, the can be imploded when it was hot enough. When the water was hot enough we put it directly under the flames to make it boil. 

Conclusion/Why:

The first time we did the experiment it failed because we didn't dip the water with the opening first. When we boiled the water we also had hot gas in the can. When we put the gas into cold water the pressure lowered. 

Water Rising Experiment & State of Matter - Hurumanu 4

Hi, guys today I will be sharing what I have been doing for science. We are learning about matter and heating. Matter is everything around us- including us! It is anything that has a mass or takes up space. Matter is made up of tiny particles. These tiny particles are arranged into either a solid, liquid or gas state. There are actually five states of matter solids, liquids, gases, plasmas, and Bose-Einstein condensates (BEC). 

States of MATTER: 

Solids meaning packed particles that aren't free to move around usually retained in shapes. Liquid meaning tiny vibrating particles are known as atoms (Is the smallest unit of ordinary matter that forms a chemical element). A liquid can flow and take the shape of a container. Many liquids resist compression. Gases meaning no fixed shape and no fixed volume. There at many spaces between particles, for example, Water Vapour, Helium, Carbon Dioxide and Oxygen. We can change between the states by either heating or cooling it down.

HEATING AND COOLING:

Deposition meaning a process when the gas turns into a solid-state without going through the liquid state. Water vapour changes directly to ice without first becoming a liquid. This is how frost is made, when frost forms on a leaf it's called deposition. 

Sublimation meaning a solid becoming a gas, for example, dry ice which is the frozen form of Cardon Dioxide. When the dry ice gets exposed to air, it starts to change from its solid state to its gas state, visible fog. 

Evaporation meaning is a liquid turning to a gas state. For instance, drying your clothes in the sun is the process of evaporation. Evaporation is also in the rain cycle it is used when water evaporates from the ocean then condensation builds to make it rain.   

Condensation meaning a process when a gas turns to liquid. Take for example the rain cycle, when water is evaporated into gas it then condensates which mean turn into droplets of water. When conditions are just right, it’s possible to see your own breath in the form of condensation.  

Freezing meaning below 0°C, you can freeze water then it turns to ice. Melting meaning heating a solid to the point where it turns to liquid. For example, if your melt ice you will get water which is its liquid form.

Convection is when heat transferred by the movement of a liquid or gas. Convection comes into play while boiling water. What happens is that the cold water at the bottom heats up from the energy from the burner, and rises up. As the hot water rises, the cold water rushes in to replace it, which results in motion circularly.

Conduction is when heat passes on heat through a material. These are both used in experiments. You can warm your back muscles with a heating pad. As the pad heats up, it transfers heat to the part of your body that it is in contact with. The heat from a hot liquid makes the cup itself hot. If you grab a cup that has hot coffee, tea or broth in it, the cup itself will be hot and your hands will feel it.

 

EXPERIMENT TIME:  

Aim: To see what happens to the water level when the candle is covered. 

Hypothesis: I think that the water will rise and up when covering it with a cup.

Materials: 

• A Petri Dish
• A candle
• A clear glass cup that is taller than the candle
• Water
• Lighter

Instructions: 

1. Put our candle in our Petri dish. 
2. Pour some water below the candle. 
3. With the matches, light the candle.
4. Cover the candle with a glass cup. 
5. Watch what happens! If you want, you can add food colouring into the water to make the experiment more visible.

Results: When lighting a candle one of the main things a candle need is an oxygen. If we limit the oxygen to a cup the candle will run out of air and will try to suck it from the bottom. That's when the water starts rising because we filled the petri dish with water. When the candle is lighted the air is hot and high in pressure. When the air is cold the pressure is low.

Conclusion/Why: The flames consume all the oxygen.
