Market Day

On Wednesday the 26th of September, it was the year 7 to 10's Market day. My company was the Rainbow cupcakes and we had fun and enjoyed being there. Today my favourite part was cooking and giving the costumers the sausages. I liked working as a team with my group and seeing people having fun and with happy faces. If I did it again I would try something different.      

Alchemy - Science

On Friday the 21st of September, in science class we did a new experience called Alchemy. I was in a group with Axle and Tukotahi. Alchemy was a old study and philosophy of how to change mental into gold. In the experiment, we used zinc nitrate solution, Zinc metal and copper/ten cent coin. We added the zinc nitrate solution in a beaker then started boiling it over orange fire. After boiling the zinc nitrate solution, we switched the fire into blue then held the coin with scissor tongs to try make the coin change to gold. 

I had fun doing the experiment but I was hoping that the coin would turn fully gold. I think we should of kept the coin over the fire for a little bit longer then the coin would of changed. 

I hope you enjoyed this.

           

Orana Park Recount

Orana Park Recount

On Tuesday the 18th of September, all of the year 7s
went on a school trip.
Our location we were going to was Orana Wildlife Park.

The first animal we went to learn about was our native Kiwi.
We learnt that a Kiwi doesn’t have hollow bones in their legs,
has no tail and their wings are underdeveloped.
They also carry their babies eggs for 28 days.

A female kiwi is bigger than a male kiwi because the female has to have enough room in there belly for the baby eggs. When the kiwi’s are six weeks old, they will be leaving their mum. Kiwi have strong legs to kick predators. They’re legs aren’t hollow like birds who can fly.   

   

After the Kiwi’s, we went to learn about a native Keas. Chocolate is toxic to Keas. Never feed your food to Keas, it is not good for them. Make sure you chase a Kea off your car before you start driving because they will fall off and die or hurt their self badly.

Did you know that Spider monkeys
has a thumb print on the end of their tail and
also use their tail for balance?

Lions have the loudest roar of all wild cats.
It can be heard from 5 miles away.  

Tasmanian Devils are marsupials and carry their babies
in their pouches.
Only the strongest four survive because the mum only
has four teats to feed from.
They cling onto each others backs to be carried.  

Tigers live alone and spray to mark their territory.

Zebras are born black and then develop their white stripes.
Every Zebra has unique stripes.

Cheetahs need to rest after they hunt and sometimes their
food gets stolen by lions or hyenas.
Cheetah are the only large cat that can purr.

The oldest ape is dominant and the young apes must give
him whatever he wants.

Giraffes tongue changed colour so it doesn’t get sunburnt.
Giraffes can kick in every direction.

 

Rhinos eat the giraffes grass at Orana park so that the giraffes
don’t eat it and get them sick.
Rhino horn is made out of the same stuff as our hair and nails
(Keratin).

Water buffalo love to swim in water, but hide from the rain.

Orangutan place bags above their heads to keep them cool and
safe from the sun.   

I hope you learnt something about these awesome animals.

Market Day

Today for business and enterprise my group and I are aiming to finish our poster by Wednesday the market day. As we finished our poster, our next step was going to make our cupcakes because we planned to make 60 and it will take a long time to make. 
I enjoyed working will my group and hoping our cupcakes will turn out great for the customers.       

Growth mindset vs Fixed mindset

Today in philosophy, my group Hope and Addyson have been creating a DLO about a growth mindset and a Fixed mindset. It was challenging to create the DLO because we had to think really hard for information and we just started that day. We hope you enjoyed and hope you have learnt something from this.

Ice Experiment

  Ice Experiment

Today in science we were doing an ice experiment. It was a mixture of water, ice cubes and salt. We also used a match and a beaker. 

I was in a group with Hope and Ranit. The challenging thing about the experiment was when we had to try to stick the match onto the ice cube and try to pick it up, and also trying to take pictures while doing the experiment. The matchstick stuck onto the ice cube because the ice cube refreezes and freezes the matchstick in place. My group and I enjoyed doing the experiment and really found it interesting. 

Why do we put salt on icy roads?

So it can stop water, rain and snow from freezing. Salting icy roads and walkway lowers the freezing points of the water.      

Geometry knowledge

This is my slideshow about my knowledge about Geometry. Geometry is a type of math that can be complicated and also fun to learn. I hope you enjoy and learn something from this.  

Business and Enterprise

In Week 10 the year 7 and 8s are doing a market day. I am in a group with Shontelle, Addyson and Kortney. We are baking 60 rainbow cupcakes with vanilla icing on top and a sweet rainbow lolly sticked on the icing. The market is held on our courts and Hornby primary and parents are invited to come and buy some of our stuff we've created. 

My group and I have named our group and we are called the Marvelous rainbow cupcakes. The cost of our cupcakes are 1 dollar and I hope Hornby primary and the parents like our cupcakes.         

Elephant's toothpaste

This Friday in science we learnt how make Elephant toothpaste. I was in a new group with Axle and Jeff. Basically, it is a mixture of Hydrogen peroxide, Dish washer liquid, food coloring and dry yeast. The reaction was caused  by rapid decomposition of hydrogen peroxide making use of yeast as the catalyst. The interesting part of the experiment was when the yeast mixing together with the hydrogen peroxide and dish washing liquid. 

Here are some photos that we took:

Elephant’s Toothpaste          7.9.2018

Resources:

• Safety glasses
• A cylinder
• Rubber gloves
• A tote tray to protect the bench from damage
• 120ml Hydrogen Peroxide 6%  
• Dishwash liquid
• Dry yeast
• Food colouring
• Funnel
• Tablespoon
• Beaker

Procedure:

1. Put on your gloves and goggles.
2. Put a tote tray on the bench and put your cylinder in the tote tray, with the funnel in the top.
3. Ask the teacher to pour the hydrogen peroxide into your cylinder (via the funnel).
4. Add 10 drops of food colouring to the cylinder (via the funnel).
5. Add a tablespoon of dishwash liquid to the bottle (via the funnel).
6. Swirl your cylinder around to mix everything together.
7. In a beaker, mix a tablespoon of dry yeast with 3 tablespoons of warm water and stir for 30 seconds.
8. Pour the yeast mixture into the cylinder (via the funnel).
9. Stand back and watch the chemical reaction!
10. Pour the mixture down the drain afterwards and wash out the cylinder.

Scientific Explanation (How it works):

The yeast and water mixture acts as a catalyst - something that speeds up a chemical reaction in another substance, while remaining unchanged itself. When you add this to the cylinder it makes the hydrogen peroxide break down into oxygen and water. The dishwashing liquid traps the oxygen in bubbles to create the foam. Just a small amount of hydrogen peroxide will create a lot of oxygen, so you get loads of bubbles - making your ‘toothpaste’ almost explode out of the cylinder.

Extra for experts:

1. Is your cylinder warm after the experiment? Why? The cylinder was warm because of the chemical reaction which produced energy in the form of heat.

Commenting challenge

This is my blog post I did in Cybersmart about the commenting challenge I am doing with my class and another class. I was explaining to you guys how to comment on someone's blog if you didn't already know. I hope you enjoy and please leave a comment.
