9/11 - Chemicals and chaos

 Today in chemicals and chaos we had to choose a terrific event that has happened in the past. I chose to research about the 9/11 that had happened on September 11 2001, this event was the worst that had ever happened. So many people had died and apparently, no one survived that was in the building or planes. 

The day was a normal day and everyone was fine then a plane got hijacked and hit the big twin building then 20 min later the small twin building got hit. In the video that I watched there were voicemails of people saying goodbye to their loved ones and say that they loved them. That day was the worst day.

Business & Enterprise kete

 For the past 3 weeks, we have been involved in the B&E kete. My role in this has been CEO, my job was to make sure that everyone knew what they were doing, I had to tell them what they need to do and to make sure that everything is sorted. Our company was called Pacific vibe, our product was Polynesian food such as chopsuey (sapasui), panakeke, fried bread and Otai (watermelon drink). 

My reflection on how the business went overall is that our food was really good and was fresh, our tables were too close to other companies and there were some messes and arguments. My reflection on the B&E overall is the whole thing was amazing and everyone's stall was amazing, most of the stalls were already sold out cause they didn't have much stuff.

Here are the photos from the day:

Expands - Hurumanu 3

 In science web, we have been looking into conduction and expansion. We had to make a stop motion about one of the topics (expansion, conducts, convection). We had to show an example of the topics, we had to make it clear so that others could tell what was happening in the slide.

In this slide, we chose to do the expansion, for the example the tube is cold and the ball doesn't fit, then once the tube is heated it expands and the ball fits. The heat gives the tube energy which the energy makes the tube expand and makes it big.

Rule of thirds - Art

  In art, we are looking at rule of thirds. It's about how an image is divided into a three by three grid. with the focal point of the photo being where the lines meet.

This is one of the sketches that I did, this image is using the rule of thirds. Each focal point of the image is where the lines of the grid cross over each other.

These drawing are ideas of rule of thirds, I drew these so I can practice how to do rule of thirds.

Particle theory and diffusion experiment - Chemicals and chaos

 This week in chemicals we are learning about particle theory and diffusion, we are working on what is and how it works. There are 6 rules on particle theory and diffusion:

1.  All matter is made up of particles
2. All particles in a pure substance are the same
3. There is space between all particles
4. Particles are always moving
5. There are attractive forces between particles
6. Temperature affects the speed at which particles move

For this experiment, we are going to put Potassium permanganate into cold and hot water to see which one diffuses faster.  

Aim: To investigate the effect of temperature on the rate of diffusion.

Hypothesis: I think that warm water will diffuse faster than cold water, because of the speed of the heat makes the potassium will move faster.

Conclusion: My conclusion was right because when we put the potassium in both the waters at the same time and the potassium spread straight away when it went into the warm water.

Plastic bags - Textiles

 What is plastic bags?

Traditional plastic bag are usually made from polythylene, its a type of thin flexible plastic film. Plastic bags are for carrying goods like food, powders, magazines, clothes and waste. It's a more common type of package. 

Why is there no more single use of plastic bags?

Sing-use plastic shopping bags are banned in New Zealand from 1 July 2019. Business cannot provide you with single-use bags. The ban will help reduce the amount of plastic in our environment.

How does plastic bags effect climate change?

Sunlight and heat melt the plastic to release strong greenhouse gasses, making the environment worst and toxic. As our Climate changes. the planet gets hotter, the plastic breaks down into more methane and ethylene, increasing the rate of climate change, and so perpetuating the cycle, plastic takes forever to breakdown which makes animals to eat it and die.

How are plastic bags made?

Manufactured and composition traditional plastic bags are made from polythene , which consists of long chains ethylene monomers. Ethylene is derived from natural gas and petroleum. Plastic shopping bags are commonly manufactured by blown film extrusion.

Alternatives to plastic bags:

• Wool bags (homemade or shops)
• Kete (flax bags)
• Baskets
• Bio degradable bags
• School bags
