Volcano Model Blog.

Hello readers,

For our last experiment for Geology science we did a Volcano model. A tiny one.

It was really fun. Our Volcano looked like this

Our Volcanoes name was Mount Ngauruhoe. This type of volcano is called a stratovolcano. It is made from ash, scoria and lava flows alternating through it’s layers.

It is found in the North Island in Tongariro National Park.  It is 2,291 meters tall, which is 7,516 feet. Mount Ngauruhoe is 7,000 years old, it is an active volcano but has become dormant since it’s last eruption in 1975.

It’s last biggest eruption was February 19th 1975.

To make it sort of look like the real deal but just a tiny model we decided to put a lot of effort into colour except you can’t really see it unless it’s close to the camera.

The chemical reaction we used to make it explode was baking powder, vinegar, dish soap and a squirt of water. The dish soap made it extra foamy.

You can also add a bit of red food dye to make it pop.

This is the end of my blog post, thank you for reading.

 

Coraline

  1. Did you like the movie?
    Yes, because it was a really spooky and nostalgic movie that I watched when I was a kid. I really enjoyed the movie because of it’s interesting features and the colourful vibe.
  2. How confident you feel about film techniques/aspects and why?
    I don’t really and it’s because I don’t know what it is.
  3. How confident you feel about writing an essay and why?
    I was confident because I like to write but it’s not easy to get the words out of my head.

Consequences of Drug Use (Toroa – Titan)

Hello readers,

This term for Health, we have been learning about Drugs. Consequences and types of drugs, whether it be illegal or completely legal. Prescribed or non prescribed and the risk of taking drugs.

Two drugs I am curious to learn about are LSD’s and Fentanyl.

These two drugs are illegal and non prescribed (Not given to by doctors). Five Consequences for using LSD’s:

  1. Extreme Changes in Mood, this relates to Taha Hinengaro (Mental & Emotional). The bliss or the high will feel good but this can change to terror at any moment. This is a negative consequence which can be ST (Short Term) 0-3 Months P. P = Personal. Because this is you taking it.
  2. Increase or Decrease Heart rate, this is in relation with Taha Tinana (Physical) this is because they heart is a physical thing which resides in your body. This is a negative consequence because it can be more harmful in the future if the substance abuse continues. ST = 0-3 Months. P = Personal.
  3. Body temperature is increasing or decreasing, this relates to Taha Tinana (Physical) because Physical can relate to your body or to what is inside of it. ST = 0-3 Months. P = Personal.
  4. Blurred Vision, this links in with Taha Tinana (Physical), Your eyes are apart of your body and you use them to look. ST = 0-3 Months. P = Personal.
  5. Loss of Appetite, this relates to Taha Tinana (Physical), because your hunger comes from the inside where your stomach is. This is Negative, ST 0-3 Months. P = Personal.

Five Consequences for using Fentanyl

  1. Poor physical coordination, this connects with Taha Tinana (Physical). This is a negative Consequence, ST 0-3 Months. P = Personal.
  2. Permanent damage to respiratory system, Taha Tinana (Physical). Negative, LT 3 months +. P = Personal.
  3. Depression, anxiety and mood swings, Taha Hinengaro (Mental and Emotional). Negative LT 3 months +. P = Personal.
  4. Suppressed immune system, Taha Tinana (Physical). Negative LT 3 Months + P = Personal
  5. Death, Taha Tinana (physical). Negative LT 3 Months + P = Personal.

 

Testing pH Experiment. (Rūku)

Hello readers,

For this unit in Science (Chemistry), We have been learning about the pH scale and did an experiment about how it works and how to use it.

  1. Aim: why did we do the experiment?
  2. To demonstrate the different types of the PH Scale when there are different chemicals, whether it be a base, acid or neutral to prove it. 

 

  1. Equipment: what did you use for your experiment?

Safety glasses, a spotting tile, a pipette, litmus paper, UI (Universal Indicator) and different chemicals. 

 

  1. Method: what steps did you complete to get your results for your experiment? Make sure your steps are numbered (like a recipe)
  1. First we used a pipette to get a few drops out of the chosen chemicals’ container. 
  2. Then we put some in the spotting tile. 
  3. We ripped a tiny piece of litmus paper off, placing a tiny bit into the chemical.
  4. When it changed colours or didn’t we listed it down as a base / acid or neutral. 
  5. Then after that we put the UI (Universal Indicator) to get a more accurate result.
  6. After that we listed it down and repeated the results until we got five chemicals down. 

 

  1. Results: Link to your results table

Table

 

  1. Discussion: starting discussion questions (you can include more detail)
    • Why did different household chemicals change different colours?

 

  • Because some of the chemicals are different and some are weaker or stronger. The stronger the darker the colour, the weaker the lighter.  To elaborate more on this is the fact that a base will have more hydroxide ions while an acid will have more hydrogen ions. 

 

  • How did you know if these chemicals were acidic or basic? 
  • I had a strong feeling that  Fabric Softener, Spray and Wipe, Dish washing Liquid and Floor Cleaner were most obvious to be basic.  Not only are they common household items, the red litmus paper turned blue and the blue litmus paper stayed blue. Which led me to believe that it would be a base and the universal indicator helped show us how weak or strong the base was. 
  • Why might Universal indicator be more useful than Litmus paper?

Because Litmus paper isn’t as accurate. The Litmus paper only tells you if it’s an acid or a base. While the Universal Indicator interacts with the hydrogen atoms in the chemical changing the colour helping you establish what is more basic or acidic. 

 

  1. Conclusion: starting conclusion questions
    • did all your experiments work – if they didn’t, why? 
    • Yes, most of them worked. I think Dish washing is between neutral and a weak base. Though it could be because we rinsed our pipette a lot to make sure we weren’t mixing chemicals. 

 

  • What could you do to improve your science next time?
  • Clean the pipette out better.

Summary of Experiments:

Hello readers,

For the past few days we have been doing Chemistry Experiments.

They were really fun.

Here is my summary.

 

Questions to answer: 

  1. What were the different experiments you completed?

Hydrogen pop test, Burning Magnesium and Lime Water test. 

  1. What observations did you make in each experiment?

In the Hydrogen Pop Test I saw some of the gas coming up and while that happened the tube was getting warmer. During our first attempt at the pop it was a failure.  In the Burning Magnesium test I wasn’t really looking because we were warned it could harm our eyes even though we had safety glasses on because of the light. The lime water test was getting cloudy after a couple of minutes confirming that Carbon Dioxide was present. 

 

  1. How can reactants from your experiment be used to predict products?

The formula helps us to predict what is gonna be made at the end.

Metal + Acid ——-> Metal Salt + Hydrogen 

Metal Carbonate + Acid ————> Salt + Carbon Dioxide + Water

Metal + Oxygen ———-> Metal Oxide. 

 

All of these metals could be any metal. 

 

What this means is that you can use any metal and still get the same result just a little different.  

Say we used Magnesium + Hydrochloric Acid ————> Magnesium Chloride + Hydrogen. 

Swap Magnesium to Zinc.

Zinc + Hydrochloric Acid ————>  Zinc Chloride + Hydrogen. 

Iron + Oxygen ——-> Iron Oxide

Magnesium + Oxygen ——–> Magnesium Oxide

Updated Predictions for The Pōrangi Boy

Hello readers,

These past four weeks we have been reading a book called “The Pōrangi Boy” which was written by an Ex TV journalist for Te Reo Maori TV. “Shilo Kino”.  Since we have been reading about this book we have had several different tasks to do relating to the book.

This task was about predicting what would happen during Chapter 21 after we read Chapter 20.

Did my Predictions change at all?
A: No. One of them was outrageous and silly but I still think it could possibly happen.

I made three different predictions. (There is one major spoiler down below)

 

 

 

My first prediction, ‘ His Koro is going to die. ‘ I predicted this because a couple of chapters before his Koro says ‘My heart hurts’ which led me to infer that his Koro was going to die of heart complicated problems.  I believed in this theory a lot and it did come true in Chapter 21.

My second prediction was talking about when Niko and Aunty Rangi went to go get Koro out of jail and after that at the house where Koro calls Niko ‘Tohunga’ which means “someone who is an expert in a certain field chosen by their tribe or spiritual practices to lead in that practice or knowledge.”, And several chapters ago he was called ‘Mowree Shakespeare’ by one of his teachers which makes me think that he’s going to use his words or make letters to protest about the prison and bring awareness to the protector of the town “Taukere” the Taniwha.  I believe in this somewhat strongly but it could be different.

My third prediction is that he wakes up in an asylum because “Pōrangi” means crazy. In which everyone called him crazy for believing in a Taniwha that hasn’t scientifically been proven to be true.

This is the end of my blog post if you have any positive feedback or advice please leave it below in the comment section.

Bottle Rocket End of Term Blog.

Hello readers, For this term we have been learning about Forces and Motions.

That being said we did an experiment involving a Bottle.

We had to make that Bottle into a Rocket, whether it be to decorate it or strategically add parts to the bottle to make it Aerodynamic. The three ways a group could win was for Most Creative / Visually pleasing, Distance Travelled and Speed.

Aim:

To Calculate the speed of the rocket, to understand the forces that acted on the rocket to show our learning of this entire unit.

Equipment: Bottle, Cardboard (optional), Paper (optional), Sharpie / Markers (Optional), Stop watches, Tape Measure, Rubber Cork, Launch Station and an Air Pump.

Method: First of all we started to look for some inspiration for the Rocket, after we had finished that we got to working on our ‘Myong’.

  1. We grabbed the bottle
  2. Then we started to wrap it in Yellow Paper.
  3.  After taping the paper on we made the Rice Hat.
  4. Using the leftover cardboard pieces we made an unfortunate decision to hot glue the fins on.
  5. We glued the hat on.
  6.  I drew a silly face on it.
  7.  We tried to tape the blue paper onto it but it fell off before launch.
  8. We filled about a third of it with water.
  9.  Then we put the Rubber Cork into the bottle attaching it to the launch station.
  10.  Then we pumped it and off it flew to a glorious 9.9 M accidentally almost hitting someone.

Results: Include distance/ time recordings, your speed calculation, and picture.

The Average time calculated from the six results given was…

1.83.

To calculate the average we added all of the results together then divided by how many times we were given.

2.22+2.0+1.81+1.42+1.25+2.32 = 11.02 then we divided that by 6 to get 1.83 s for the average time.

To calculate speed we use the distance travelled divided by the average time.

9.9M divided by 1.84s = 5.4m(ms-1)

Distance travelled (m) : 9.9 m
Time taken (s) :  2.22s, 2.0s, 1.81s, 1.42s, 1.25s & 2.32s

 

Speed calculation (ms-1)

Distance / Time = 5.4m(ms-1)

9.9 M

Discussion:

What are the forces acting on your bottle rocket?

Thrust, Drag, Weight and Air Resistance.

Are they balanced/ unbalanced?

Unbalanced.

What is net force and how does this relate to the forces acting on your bottle rocket?

The total forces combined of all of the forces acting on an object. Which is making it go upwards further and then drag comes into action to make it have a slower fall.

There are four main forces acting on this rocket, Air Resistance from the fins on the rocket, Drag because it is falling after take off, Weight because of the amount of water and items added onto the rocket Thrust because of the take off since the pumping helps assist it in going further and faster.

What are the strength of forces acting on it at different stages?

Thrust at the start is greater than anything because it shoots off helping to propel it through the air. Drag during the last two stages because of the Weight which drags it down through the air to come to a stop.  Air Resistance helps it have a safer fall during the last few stages. Weight just pulls it down.

How do the forces acting on the bottle rocket affect the motion of the bottle rocket at different points?

Thrust helps it shoot off from the ground making it travel faster, Drag pulls it down with Air Resistance which does help it have a safer fall while weight does pull it down too because of the amount of items on the bottle.

 

Why do you think results may vary in the class?

Because some people might’ve gotten a further distance and longer times or some might’ve travelled slower but achieved faster times.

Conclusion:

How was your bottle rocket successful/unsuccessful and why (relate your answer to physics ideas)?

Successful because it launched and went a little far.

Unsuccessful because it hit someone. How could you improve it?

Make the hat more pointy

Why  does Sportsmanship matter ?

  • Because it’s fair
  • Honesty if you did something wrong
  • A good environment for everyone
  • Whether or not you win or lose you still wish everyone well off after the game.
  • Teamwork is a good thing.
  • Officials, Subs and people on the sidelines are also people too respect them.

In Soccer, Basketball and many more sports it is Sportsmanship to:

  • Not trash talk
  • Not Being rude to the opponents
  • Accidentally fouling someone
  • Being fair and honest
  • Not bending the rules
  • Not arguing with the Officials.
