Nitro Type Race

Today in English we were given 15 minutes to do whatever we like as long as it relates to literacy.
So I played a game called NitroType.
One of my friends, Greg, invited me into a room with Reige to do a typing race.
Greg was obviously going to win regardless of the effort we put in.
His typing speed is more than twice that of the speed of mine.

SoundTrack of my life

In English, we were told to make a slide consisting of our favorite songs and the reason why we like them, the slide is to be titled "SoundTrack of my Life".
I couldn't add a theme onto it for it ruins the structure of the slide so I left it as default.

Whare Tapa Wha

Whare tapa wha is about our haoru, our 4 dimensions of wellbeing, Social, Mental, Spiritual, Physical.

This is house NO.2, I made it all by myself while the others make house NO.1. House NO.2 is simply a backup house just in case the first house doesn't work out. the first house didn't work out and ended up looking like a broken box, so we decided to use the backup house.

The 4 walls of the whare resemble the 4 dimensions of the whare and the roof resembles the entirety of the whare.

Table Tennis Ball Drop

Aim:

To see how high the ball bounces in relation to how high the ball is dropped.

Hypothesis:

The higher the ball is dropped, the higher it bounces.

Method:

Drop the ball in a certain height then measure the height of the bounce, repeat this process at least 3 times and collect the data. Compare the data and calculate the average.

Independet Variable: Height dropped.

Dependent Variable: Height measured.

Control Variavble: Height bounced.

Chart:

Hieght Dropped	50 cm	100 cm	150 cm	200 cm
Trial 1	24 cm	46 cm	47 cm	70 cm
Trial 2	25 cm	44 cm	60 cm	71 cm
Trial 3	28 cm	43 cm	52 cm	72 cm
Average	25.66  cm	44.33 cm	50 cm	71 cm

Graph:

Conclusion:
It was pretty obvious that the higher you drop the ball, the higher it bounces. So, why did we do this anyway? To practice making graphs.

Math Problem

You were invited to join a discussion for the future of learning, there are 20 people there (including you) and everyone's going to handshake each other once. How many handshakes are going to occur?

Though many may think at first that the answer is 380, that answer is incorrect.
So, How did we reach the answer of 380?

there are 20 people and everyone is going to handshake each other, but they can't handshake themselves. So many people may think "19x20=380".

Imagine this, you are in a group of 4 and you are going to handshake everyone once.
you handshake 3 people, the second handshakes 2 and the third handshakes 1, while the fourth doesn't handshake anyone for he/she already shook the others hands. making it only 6 handshakes.

How do you solve this? many at this moment "19+18+17... 3+2+1". how do you simplify this?
There are 2 tricks, The simplest one is working on 3 smaller cases and trying to find a pattern.

4 people = 6 handshakes. And if we used the wrong way, we get 12 (3x4) cause you can't handshake yourself.
5 people = 10 handshakes. Using the same wrong technique, we get 20 (4x5)
6 people = 15 handshakes. Again with the same technique, we get 30 (5x6)
Can you see a pattern? if we use the same technique, we always get twice more than the correct answer.
19x20 =190
    2

This is the second trick. you split 20 into 2 groups, 1-10 and 11-20 (no, this is not subtraction).
You add the smallest number of the smaller group to the largest number of the largest group, 1+20=21.
Then you do the same thing again only with the second smallest and the second largest, 2+19=21
Then the same thing with the 3rd, 3+18=21.
Can you see the pattern? You multiply the answer with the largest number in the smaller group, which would be 10 and you get the answer of 210, but you can't handshake yourself, 210-20=190.

Right now I'm stuck in a problem and I only have 3 minutes to solve it. What's that problem you ask?    I blogged about the wrong thing...

PICTUREPEDIA

I am currently reading a book called Picturepedia.
As the name suggests, Picturepidea is an encyclopedia that contains information and pictures.
Picturepedia doesn't just cover facts regarding science but it also covers facts about history, religion, cultures and much more.

BellWork: It CAN'T Be TRUE!

I've been reading a book simply about random scientifical and mathematical facts.
It's called "IT CAN'T BE TRUE!"

The book author is Dorling Kindersley.
It contains random facts such as what animal has the largest eyeball? Or what is the largest insect? etc.

The thing I like about this book is that it shows an actual visual representation and comparison of the object's scale.

The most surprising fact that I've read is the size of a comet's coma. A coma of a comet is made out of small particles breaking away from the nucleus and can spread as nearly as big as Jupiter.
