Science Roadshow

The whole class had to pay $2 to attend the Science Roadshow, some of us didn't get to pay so our homeroom teachers' covered up for them for free! For 50 Science Inventions that we get to experience and try out! We spent the whole period 1 & 2 on the Learning Street in the Science Room with 7TZ.  The other year 7 classes went There we were introduced to Shane the MASSIVE GUY & Samantha. Shane showed us fire in ice and did an experiment about it.  The experiment was the ball the couldn't fit in the hole, he asked for a volunteer in the audience, Shontelle, in my class, was picked because she was the first one who raised hands. Shane told Shontelle to put the ball (It was an 8 numbered ball from billiards) on the hole (those wands) it did, but when the hole with the handle was put in a small bucket filled with liquid nitrogen. Shontelle and Shane used safety glasses and gloves for safety of course, Shane took out the hole with the handle and it was smoking and freezing cold! Well like a cold smoke coming from your freezer, then Shane told Shontelle to put the ball on top of the hole to see if the ball still goes through but surprisingly the ball got stuck in the hole, it didn't go through, Shane asked Shontelle to do it again and it did the same thing. You knew you lick a popsicle and it so cold that your tongue sticks to it? Well, I feel like that's what exactly happened.

The next experiment we did was burning a galvanized sheet metal (A galvanize is coated with zinc, when a metal gets rusty because of the weather and temperature it makes a metal rusty and to recycle it, they coat it with zinc so it can be used).  The fire changed colours from yellow-ish orange to lime-ish colour, it made galvanized sheet metal melt and turned into glass and turned a hole in the middle.

After all the experiments, we explored and tried all the inventions, they were all pretty cool, there were so much questions in my head in each and one of them, I wish I can tell them to you all but all of you might get bored so I'm just going to make this blog post shorter.

Passion Project Update

26.11.18

Today, Mr Mitchell went around and drilled holes for some of us for our design, our design is He Matau (Fish Hook), I also started adding details to make more like a 3-dimensional design and to add some texture to it.

Tools I used: cheese grater for stones, file, rasp, flat chisel, hammer/mallet, pencil, sandpapers and etc.#

Personal Comment:

Even though our clothes got dirty, it was worth it though, because our hard world always pays off, it'll be worth it in the end. Some of us broke their stone but they can always change it into something even better.  Some designs don't have to be perfect, but it can be wonderful just the way it is, we just have to focus on the progress, not perfection.  

My next steps: I need to work on the hole and the shaping.

Feedback to me, myself, and I: I really like my design because I worked really hard on it. I am actually pretty proud of myself. 

SLJ About Me, myself and I

Hey, Emma.

I'm Skyler A and I am in year 7, 12 years old.  I am an only child and I want siblings (maybe twins). I am from the Philippines. I like to draw, read, listen to music watch T.V and watch movies and dramas, I like Kpop.  I like to hang out with my best friends a lot. 

Rieya had the Dalmatian dog filter and I have the other dog filter.

 Rieya was doing the peace sign.

I want to join Summer Learning Journey because I get to win a prize and it can improve my reading and writing and I also get to learn new things and do fun activities, it's also a good opportunity for me and other people who are wanting to join or the people who joined Summer Learning Journey. If I win the Summer Learning Journey, I want to win a prize that I really need and I really want.  I want to get a drone because I sometimes travel to different places and also If I travel in the future too.  It's also good for exploring.  

Colour changing cabbage

Today we did an experiment that had to do something with the pH scale, what colour will the cabbage turn. I was grouped with Megan and Rieya. I think that our group worked really well especially with participation. First, we broke the cabbages into pieces before putting it in the blender because we saw what the other groups did, they didn't break it into pieces, that's why there were big clumps, after that, we added water to it because we want it to be liquidy and we want it to be easier to blend. We were really surprised, satisfied and amazed by the colour turned out.

Purple Cabbage Experiment

Last period in science we looked at the pH scale. Today we are going to make a purple cabbage indicator that will test the acidity or alkalinity of white vinegar and washing powder. The indicator is neutral and has a pH of 7.

Answer the following questions before you start the experiment.

What colour do you think the white vinegar will turn the purple cabbage indicator? I think it might turn the colour to a lighter colour like maybe white, green, pink, red.

Why do you think this? because of the vinegar’s strength and because it’s acidic

What colour do you think the washing powder will turn the purple cabbage indicator? I think the colour will still be purple

Why do you think this?  because the washing powder is alkaline  

Method:

1 Peel off three or four big cabbage leaves and put them in a blender filled half full with water. Blend the mixture on high until you have purple cabbage juice.

2 Pour the purplish cabbage liquid through a strainer to filter out all of the big chunks of cabbage. Save the liquid for the experiments to follow.

3 Set out three beakers, side by side. Fill each glass three-quarters full with cabbage juice.

4 Add a little vinegar to the first beaker of cabbage juice. Stir with stirring rod and watch the colour change.

5 In the second beaker, add a little laundry detergent and stir.

6 Take a photo of your 3 beakers side by side.

Reflection:

Were your answers right or wrong? For the white vinegar one, I was right, it was red-ish pink but I got it wrong with the washing powder

What number do you think the white vinegar would be on the pH scale? Maybe 3 or 4

What number do you think the washing powder would be on the pH scale? Maybe 8.5? Or 9.5

This was the colour before

...And this is the colour now

The white vinegar turned the colour into red-ish pink and the washing powder turned the colour into green-ish blue.

Passion Project Update

22.11.18

Today was the day when we finished carving, filing and etc. I finished the koru and we're starting doing a new one, a fish hook.  I really liked how my koru turned out and I was also starting to like the fish hook too.

We're going to continue on the fish hook on Monday because we needed time to finish it. I've also learnt something, not to carve too much of the stone because it might and if it breaks, you'll have to make the design smaller. 

:)

Monday

Today, we had to start sanding the stone with a sandpaper, we have to use the yellow first before the white one. Mine was really smooth, well it's stone so, it's can't really be that smooth as those professional ones.

We spent the last hour here in J1 to do our plan, our final plan actually, for our big stone.  I came up with a "Pikorua Twist".
Pikorua Twist symbolises the bond between two people, whether it's based on love, blood and friendship. It connects the spirits of lovers, family and friends, it also represents their life path.

There is also a Koru inside the twist, I'll show a picture later, anyway, Koru represents harmony, new life, growth and strength.

On my paper, my design (and the meaning) also says how it's related to me and HHS (Hornby High School).

I'm really proud of my drawing, I think it's really clean, pure and amazing. I can't wait to carve my design on the stone.

SLJ Japan

Konnichiwa こんにちは minna-san, today on cybersmart we had to look through different countries and choose one of them to research about, I picked Japan because I've been wanting to go there since I was little and I'm a big fan of their dramas, anime and manga's and plus there's a lot of places you can visit like Mount Fuji. I also want to learn more about their culture, language, people and amazing places in Japan.  My dad also used to work in Japan for three years and he told me that there's a lot of beautiful places in Japan.

The capital of Japan is Tokyo
The population of the capital which is Tokyo is over 36 million
The weather of the capital in January is usually winter
Japan is located in the east of Russia, China and Korea
There is only one official language spoken which is Japanese

What is "Capital?"
Now capital letters but the other meaning of capital, like the capital of Japan which is Tokyo, it is where the parliament is or where the highest court of justice is. Like Washington D.C, it's where the white house is and is now where Donald Trump lives.

Fun facts about Japan:
In Japan, black cats are considered a good luck.
Even though there are traiditional sports in Japan like Sumo Wrestling and etc. Baseball is the most important sport in Japan (it is known as "Yakyu")
Who is the president of Japan? it's Shinzo Abe

Passion Project (Stone Art: Carving) Update

15.11.18

Every Thursday, we come to school at 9:40, well that's our school time but we can go earlier than that to school, until the end of the term. We carved a koru out of a stone, it's one of those soft stone that you use for carving. Monday was when we started carving and working, it was pretty fun, there's no school tomorrow because it's holiday! Anyway back to the carving thing, we almost finish the stone.  I designed a Maori Design, I have two choices, it could either be a Mangopare (Hammerhead) and a Pikorua (Twist).

Amphibious Cycle and Filters

Today, on cybesmart, we researched some questions to find the answers, we've learnt how to use the filters properly, and also the answer to all the questions, like what Steven Adams looked like when he was a rookie.

There is also one question we had to research about, it's something to do about a machine in 1932, luckily, I found out what it was, an "Amphibious Cycle", an Amphibious Cycle is a machine that can both go on land and water, it is a bike filled with air. The main purpose of this invention is to be able to transition from both land and water. It's a weird looking bike but I would want to ride it.

Ph Scale

In science today we did a quiz about the pH Scale. We had to do 2 tasks to finish it. At first, it was a wee bit difficult for me to make the scale but I finished it.

Task 1

Complete the quiz below

Neutral solutions have a pH of 0 7 14

What colour represents neutral on the pH scale Blue Red Green

What is the range covered by the pH scale 0-14 -10 - 10 0-100

pH is a measure of ____________ ions Oxygen Hydrogen Hydroxide

Acids and bases can combine to create water and salts True False

Which is not a property of a base Sour taste Bitter taste Slippery

There are a variety of strengths of acids and bases True False

Vinegar is an example of a Strong base Strong Acid Weak Acid

An acid’s pH is between 0-7 7-14 14-21

What is true when acids and bases neutralize each other;

Water is produced Salt is produced Both water and salt are produced

Does baking soda have a pH of 9?   Explain your answer

Yes, it does, because it is mostly used for baking and experiments.

______________________________________________________________________________

Task 2

Create a doc illustrating the pH scale.
