Alchemy - Science

Today in science we studied alchemy. The aim was to try and turn a copper coin into gold. The equipment we needed was: 

• Copper coin
• Bunsen burner
• Tripod
• Heat mat
• Gauze mat
• 50ml beaker
• Scissor tongs
• Zinc metal
• Zinc Nitrate solution

My group is Jeff, Callum and me

Here are photos we took:

• putting in the Zinc Nitrate solution

The coin.\



I was actually hoping the coin would change gold, I thought it would but it didn't.
it was fun changing the coins colours.
Have a good week end.

Orana park

Yesterday the year 7s went to Orana Park. The animals we saw were Kiwi, Kea, Spider monkeys,
Tigers, Lions,
Tasmanian Devil, Gorillas, Orangutans, Rhino, Giraffes, Zebra, Buffalo and Cheetah.

My favourite animal was the Zebra. Do you know if Zebras are black with white stripes or white
with black stripes?

Did you know that Orangutans wear sacks to protect them from the sun or rain?

Did you know that big cats don’t purr? You know normal cats purr but big cats don’t.
Cheetahs on the other hand they are the only big cat that purr.

If you go to Orana Park check out the emu, you can hear them talk. Their talking sounds like drums.
Straight drums.

Spider monkeys use their tails like a 3rd limb. They use their tail as support to keep
-their balance when they are swinging on their rope.

Tasmanian Devils have sharp teeth. They may look cute but they're actually endangered because they
have a face trauma and if they bite each other it will spread.
Tasmanian devils carry their babies in pouches.

Did you know Kea are really smart but also really naughty. Chocolate is toxic to them as well.

Kiwis need strong legs so they can kick they predators. They don’t have hollow legs like normal birds do.
Kiwis can’t fly because of their wings that aren't structured fully.

Did you know that a rhinos horns are made out of the same stuff as your Finger/toe nails and your hair?
This is known as keritan.

Giraffes tongues were actually pink but they turned purple to protect it from getting sunburnt in the hot
weather where they're from (South Africa). Giraffes can also kick in every direction.

Kiwis hold their eggs inside them for about 28 days and when their little baby is 6 weeks
old they go and live by themselves.

The oldest ape is the big brother boss, you must give him everything he wants.
The big brother is a silver back but the other 2 apes are younger.

Did you know that you can hear a lions roar from 5 miles away?

Our leader was Elaine she was really nice. We all had fun at Orana park.
We even got to hold a Rhinos horn.

Growth mindset vs Fixed Mindset

Today in Philosophy we were learning about growth mindset and fixed mindset. 

Growth mindset is when you have good thoughts about your work and your self. You achieve you goal and you don't down raise your bar. 

Fixed mindset is when you have bad thoughts about your learning and you don't achieve you goal. You don't finish it in time and your not focused. 

I am working with my friends Addyson and Anneleise.

This is our DLO.

Even though it is just a picture it does explain a lot.

For me it was a challenge because I have just learnt about growth mindset and fixed mindset today.

Thanks for coming to visit my blog!.

Ice expeirement

Today in science we had to make ice stick to a match. At first I thought it was impossible then me and my buddy's Anneleise and Ranit did it, it was so cool.

You have to put the match stick on top of the ice and then sprinkle salt on top and wait for 30 seconds and then the match stick will stick to the ice. 

The ice also brings down the level so the water freezes, so the ice can melt faster. 

This lets go of all the frozen energy when there is warm heat around it, so it all gets colder including the ice.

The ice cube freezes so it freezes the match stick to the ice.

The challenge to me was dropping the match stick on to the ice because it wouldn't stick straight away, it also kept slipping out of place.

Here are some photos of how the experiment went.

Lifting the ice with the match stick:

This experiment was awesome. I didn't believe this will work, but it did.

If you tried this do you think it will work?

Why do we sprinkle salt on icy roads?

To make the ice dissolve quicker so that cars don't slide on the ice.

Elephants Toothpaste

Do Elephants use this to brush their teeth?.

Today in science me and my buddy Vann made some elephant toothpaste.
The ingredients for elephant toothpaste is
:hydrogen peroxide.
:dish washing liquid.
:and mixing dry yeast with water.

The colour was a light green type of colour, and the smell was DISGUSTING!!! It sort of smelt like rotten eggs and vinegar.

Here are some photos of how it went.

Hydrogen peroxide:

 Food colouring:

 Mixing the food colouring:

 Getting ready for the yeast :D :

Mixing the dry yeast:

POOF:

The yeast had a reaction with the other chemicals and that made the elephant toothpaste go POOF.

Doing science experiments are really fun to do.

Geometry knowledge

In math yesterday and today we have been learning a little bit a geometry. Geometry is a type of math that is about shapes, properties and size.
Here is my slide show about my geometry. 

I hope you learned more about geometry now.

have a good weekend.

Advertisement Wizard - wand

In Kete we have been learning about business and inter-prize. For this Kete we had to make our own advertisement. Our teacher Miss Allan picked random topics for us. My friend and I had to make an advertisement about a wizard wand. Here is our product.

                     

That is mine and my friends product. If you were wondering what the Terry house is its the ware house but named after one of the year 7 Teachers.

Leave a comment of how well you think me and my friend did. :D

Make a paper clip float

Does a paper clip float or not?.

The things you will need is:

clean dry paper clips
tissue paper
a bowl of water ( We used beakers )
pencil with eraser

What we need to do is:

 Fill the bowl with water to try to make the paper clip float

Tear a piece of tissue paper about half the size of a dollar bill

Gently drop the tissue flat onto the surface of the water

Gently place a dry paper clip flat onto the tissue (try not to touch the water or the tissue)

Use the eraser at the end of the pencil to carefully poke the tissue (not the paper clip) until the tissue sinks. The tissue will sink and leave the paper clip floating!

It works with a little something scientist call Surface tension. Surface tension basically means there is a sort of skin on the surface of the water. Where the water molecules hold tight together. If the conditions are tight then it will be strong enough to hold the paper clip. The paper clip is not actually floating by it self it is being held up by the surface tension. Many insects such as water strider use this skin to walk across streams. 

I think mine will float because it seems easy enough when I saw my classes paper clips float.

Here are some photos of how it went.

With the tissue

Sunken

My experiment was unsuccessful. 

I saw every ones else paper clip and it was floating so I thought mine was going to float.

Did you try to make a paper clip float?, you should.
