What have we learnt in Maths

Here's what we learned about Maths solving and doing fun stuff in Maths. Hope you like it.

First, we made a sundial made out of wood craps, sundial is a clock that tells time like normal clocks do but sundial is different, sundial use sun to tell the time by casting the shadow from the the stick pointer on the middle of the sundial which is called gnomon. Sundial can't work in night time because there's no shadow casting the gnomon to tell the time. The sundial is useless if the cloud covering the sun's sunlight. We also learned many different clocks like candle clock, water clock, sundial clock, hour glass, and other different clocks.

We also send some emails to Dr. Frank King of what we think about his sundial article, he's an Britain's expert of sundial and knows how sundials really works.

Second, we made a fun fact large numbers, here's the three questions that I think it's fun to know in large numbers.

1.) How many living things are on Earth? There are currently about 75,000,000,000 ton of living things on Earth.

2.) How many leaves are on Earth?
There are about 120,100,000,000,000,000.
3.) How many heart beats do 80 years old can do?
It's about 3,363,840,000.
I only search this from google because it's fun to know of what you don't or I don't know.

Third, We did large units numbers, large units numbers are like million, billion, trillion or more.
What do you know about large numbers? Today your gonna learn many large numbers ( I think ).
1.) Million 2.) Billion 3.) Trillion 4.) Quadrillion 5.) Quintillion 6.) Sextillion 7.) Septillion 
8.) Octillion 9.) Nonillion 10.) Decillion ( That's all I know )

Fourth, We made a google doc about space travelling around the solar system.
(Sorry if you can't see the numbers, zoom it so you can see it clearly).

Fifth, we made a google doc about the power chart like bytes kilos or power of kilos.

Sixth, we did something like a fraction of part of the whole and make it to percentage %.

First we need to find out what's the whole, then we subtract the small distance km to the large distance km. 

Ex:

Mercury to Venus.

1.) We need to find out what is the distance of Venus and Mercury, Mercury has 57,900,900 km, Venus has 108,200,200 km, Venus has the large distance than Mercury, we then subtract Mercury's distance to Venus distance. The whole part distance is Sun to Neptune.
