 Aim:

To make a wind racer.

Research:

Youtube

Equipment:

-Trolley

-Bamboo/metal rod

-Cardboard

-Newspaper

-Tape

-String

-Plastic Bag

-Popsicle Sticks

Method:

1.Put the metal rod in the trolley.

2.Cut pieces of material into squares.

3.Draw on the paper for creativity.

4.Gather and cut pieces of tape and string.

5.Stick the materials to the metal rod.

Result:

Discussion: 

The four forces acting on the wind racer were:

Gravity: The wind racer didn't fly in the sky, and the wind made it fall over.

Support: The ground kept the wind racer up.

Push: The wind pushed the wind racer.

Pull: The wind racer stopped.

Why did it slow down?

I think the main reason was that we didn't have enough spacing for the bag to catch the air, another reason is that the leaf blower was too far away and was a bit too weak to reach the wind racer.

Conclusion:

The wind racer didn't exactly go the first time we did it, but once we reset and tried again it kinda worked but didn’t go that far. Next time I would probably angle on how I am blowing onto the wind racer so it could make it a bit more further or make the plastic bag a bit looser so it can catch some more wind.

Making salt crystals - Science

 Aim: To produce copper sulfate salt by reacting copper oxide with an acid.

Equipment: 

• Copper oxide powder
• Dilute (0.5 mol L-1) sulfuric acid
• 50ml measuring cylinder
• two 100ml beakers
• Bunsen burner
• Tripod
• Gauze mat
• Funnel
• Filter paper
• Thermometer
• Spatula
• Evaporating basin
• Stirring rod

Method:

1. Add 20ml of sulfuric acid to a 100ml beaker. Heat the acid until it reaches 70℃. Turn off your bunsen burner.
2. Once heated, use a spatula to add pea-sized portions of copper oxide to the beaker. Stir the mixture for 30 seconds
3. Repeat step 2 until no more will dissolve. Allow the beaker to cool.
4. Fold the filter paper and place it in the funnel. Place the filter funnel into the second beaker.
5. Make sure the beaker is cool enough to hold at the top. The contents should still be hot. You may need your teacher to complete this step.
6. Gently swirl the contents of the beaker to mix, and then pour into the filter paper in the funnel. Allow filtering through.
7. Rinse the beaker you used to heat the mixture previously, and place it back on top of the tripod filled with 50-60ml of water.
8. Place the evaporating basin on top of the beaker and carefully pour some of the solutions from the beaker into the evaporating basin.
9. Gently heat the beaker until the solution in the evaporating basin has reduced by half.
10. Leave the evaporating basin to cool. Once cool, move the evaporating basin to a warm place where it will not be disturbed (i.e. a window-still) and observe over the next few days. Blue copper sulfate crystals should form.

Results:

The end results turned out great and actually turned into crystals.

Discussion:

A Copper (oxide) + sulfuric (acid) >Water + copper sulfate.

Copper oxide and sulfuric added together makes water then the water turns into copper sulfate (crystal)

Conclusion:

That the acid actually made into crystals, and the chemicals reacted together.

 Let it be - Beatles

When I find myself in times of trouble, Mother Mary comes to me
Speaking words of wisdom, let it be
And in my hour of darkness, she is standing right in front of me
Speaking words of wisdom, let it be

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

And when the broken-hearted people living in the world agree
There will be an answer, let it be
For though they may be parted, there is still a chance that they will see
There will be an answer, let it be

Let it be, let it be, let it be, let it be
There will be an answer, let it be

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

Let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be, be

And when the night is cloudy there is still a light that shines on me
Shinin' until tomorrow, let it be
I wake up to the sound of music, Mother Mary comes to me
Speaking words of wisdom, let it be

And let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

And let it be, let it be, let it be, let it be
Whisper words of wisdom, let it be

This song was made by Paul McCartney. It was inspired by his mother, Mary, who died when he was 14. Most people thought this song was a religious song because it said "mother mary" although he didn't mind people thinking that he did want people to know it was about his mother. 

10Health - Bullying

 In health, we had to choose a topic that relates to Taha Whanau and to make a DLO about what we know of the topic. I chose bullying because it seem that I knew more about this specific topic than all the other topics, then we had to answer the questions that we were given in the slide. 

Distallation - Chemicals & chaos

                                                               Distillation

Recap:  Last lesson we learnt that the process of evaporation is when a liquid turns into a gas. So we can separate a solution, by evaporating away the solvent to learnt a solute (solid). 

But what if we want to collect gas?? When we trap the gas and turn it back into a liquid this is called condensation.

What is it?

• Evaporation: heating a liquid, turns to a gas
• Condensation: cooling down a gas, turn into a liquid.

Experiment:                                  Separating a mixture using distillation

Aim: To separate a solute from a solvent in a solution using distillation.

Equipment: 

• A solution of saltwater
• Conical flask
• Heatproof mat
• A delivery tube and bung
• Bunsen burner
• Tripod
• Gauze mat 
• Retort stand
• Boss head and clamp
• Boiling tube

Method:

1. Set up the equipment as shown in the diagram
2. Add approximately 50 ml of saltwater to your conical flask
3. Light your bunsen burner. Open the air hole and gently push the bunsen burner under the tripod
4. Heat the solution until most of the solvent has been evaporated. Turn off your bunsen burner.

Hypothesis: When the coke is heated the sugar will solidify and stay in the flask and the liquid will be evaporated and travel all the way to the test tube and cool.

Observations: As soon as we put the Bunsen burner on the coke was already boiling, when the coke started to evaporate it was transferred through the bung and into the tube where it cools and turns into clear brown liquid.

Conclusion: Coke Zero has had less dissolved substances, when normal coke had more dissolved solids which was sugar.

Serial Dilution

 Aim: To make a dilution series to investigate concentration.

Hypothesis: I think that the potassium permanganate will slowly dilute as we tip 5 ml of every test tube into the next test tube.

Equipment:

• A potassium permanganate crystal
• Six large test tube
• Tweezers
• A plastic transfer pipette
• A test tube rack
• 10 ml measuring cylinder

Method:

1. Place 6 test tubes in a test tube rack. Label the rack with numbers 1-6
2. Using the measuring cylinder, fill test tube 1 with 10 ml of water. Fill the remaining test tube with 5 ml of water.
3. Using your tweezers, add a single crystal of potassium permanganate to test tube 1
4. Gently shake the test tube until the crystal has dissolved
5. Using the transfer pipette, carefully remove exactly 5 ml from test tube 1 and pour it into test tube 2
6. Rinse the transfer pipette thoroughly to ensure that no purple solution remains
7. Gently shake test tube 2 and repeat the transfer process, transferring exactly 5 ml of solution from test tube 2 to test tube 3.
8. Rinse the pipette again and repeat the transfer process for test tubes 4, 5 and 6.

Discussion:

Which was most dilute? Test tube 6

Least diluted? Test tube 1

Most concentrated? Test tube 1

Least concentrated? Test tube 6

How fo you know? With the most diluted the colour of the liquid has less colour to it and the most concentrated is the brightness of the liquid.

Filtration Experiment

Aim: To separate a solution from a precipitate (precipitate is the name for a solid that forms in a liquid during a chemical reaction.) 

 

Solvent - Thing doing the dissolving (liquid)

Solute - Thing being dissolved (solid)   

Solution - A mixture that is formed.

Filtration - Separates particles based on size.

Filtrate - Liquid after it has been filtered.

Mixture - 2 or more substances together

Solubility - Ability to dissolve.

Hypothesis: What do you think will happen 

Equipment:

• Copper sulfate
• Conical flask
• Stirring rod
• 200ml beaker
• Funnel
• Filter paper

Method: 

1. Pour approximately 50ml of copper sulfate solution into a beaker. 
2. Add the same volume of sodium carbonate solution. A reaction will happen, you should see a cloudy blue precipitate form. Called copper carbonate.
3. Watch demo then fold filter to fit inside the funnel.
4. Place the funnel with the filter paper inside of it, into the mouth of a conical flask.
5. Stir the mixture in the beaker, then carefully pour it into the funnel.
6. Observe what happened.

Observation and Discussion: What you saw happen and why do you think it happened?

When you add the liquids together they start making a bright blue coloured liquid. When you start to filter the liquid through the filter paper there are blue solids on the top and clear liquid coming from the bottom, the reason is that the blue cannot fit through the filter paper because it has large particles in it but the clear liquid has small particles which fit through the filter paper.

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.

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

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

Well being - Wananga

 In the last 2 weeks we have looked at Resilience - Emotional Awareness (understanding emotions) and impulses, I have come to realise that my emotions actually have effect on people around me.

Being able to control my emotions in different situations avoids:

- Breaking relationships with others

-  Mental breakdowns

- Healthy social well being

- Anger issues

- Conflict

Knowing how to react and respond in situations rather than acting on impulses means that not getting myself in trouble by making or doing something wrong. The effect that things have on my Social well being (Taha Whanau) when your being kind to someone your relationship becomes healthier but when your being unkind and rude to someone your relationship becomes unhealthy and is toxic.

30 sec film - Inside and out

1. What was the film about? 2 people playing a volleyball game but something goes terribly wrong

2. Something I enjoyed while making my film? All the laughs and us having fun with the video

3. Something I learned while making my film? That you shouldn't work with friends or people you can't focus with other wise you won't get work finish

4. Some film techniques I included were:

• Low angle
• High angle
• Eye level
• Birds eye view
• Long shot (wide)
• Close up

5. Something I found challenging was:

• Getting angles
• Making sure we got all the scenes

6. What I would do differently next time? 

- Go in a group with people who I work well with

- Have more ideas for angle shots

What is Gelato?

What is gelato?

Gelato is a popular type of ice cream which is from Italy. 

What’s the difference between gelato and ice cream? It starts out with a similar custard base as ice cream but has a higher amount of milk and a lower amount of cream and eggs (or no eggs at all). It is churned at a much slower rate, incorporating less air and leaving the gelato denser than ice cream.

Why does gelato have so much flavour?

Gelato has less sugar than what ice cream is and when you eat the gelato it instantly melts in your mouth so it gives you a quick burst of flavour.

Digestive system - inside and out

In science, we have been working on the digestive system last week. We had to make a DLO of the digestive system, in the DLO we had to put each of part of the digestive system, then we had to explain what they do and how they help our body to stay alive. We were allowed to go in pairs  so I went with someone in my class here is the DLO we had made:

Characters strengths - Film study

In film studies, we have been given independent work for when we have finished the work that we had been given. For this independent work, we have to choose 2 characters out of the movie and write down what their strengths are, my 2 characters are Coraline and the Other Wybie. 

Coraline: Curiosity and bravery, the reason I chose curiosity was that at the start of the movie when we see her arrive at the house she starts to look around the house and then once she was unpacking the boxes she found the small door but when she opened it, it was empty. The reason I chose bravery was that at the end she found out that she needed to find her parents and the ghost children's eyes and for her to do that she needed to play a game, instead of her crying because she misses her parents she thought about others a fought hard for them back. 

The other Wybie: Kindness and Bravery, the reason I chose kindness for Wybie was that at the start when we first met him we were really nice and actually care about Coraline and at the end, he put his own safeness away from and try to save Coraline. The reason I chose bravery for Wybie was that at the end he was saving Coraline from the other mother and stepped up to the other mother even though he was scared of her he still stood up to her and saved Coraline.

Challenge chart - Inside and out

This week for film studies we had to make a presentation for a challenge chart about 2 characters in the movie, we had to put the challenges they faced, how they reacted and what showed us about that characters. The 2 characters I chose was Coraline the main character of the movie and the other mother. The reason I chose these two characters was that they were showed more in the movie and we could see who they actually are. 

What am I learning?

Understanding how characters are developed in a film.

How does this work show my learning?

I created the show I can understand how the characters developed in a film.

What am I wondering as a result of this learning?

Is there other ways to show this working.

Photo montage - Art

In these few weeks of art we have been looking at art montage and trying it out ourselves, you might be wonder what is a photo montage well I'll tell you. Photo montage is a collage of a bunch of photos bunch in to something that is weird or different. Our art teacher had given us several photos of objects or people and a white piece of paper, then we had to be super creative and try to make something out of those photos. Here is my work that I did:
