Flame

• Flames are made of Plasma, gases that are heated to the point they have lost some of their electrons. 

• Flames are magnetic, most flames are repelled by magnetic fields. 

•On the international Space station there is no gravity so candle flames won't take a teardrop shape, instead they burn as a sphere shape with blue tinge. 

International Space Station

• The international space station is the largest man made object in space. 

• There is no up or down in the International Space Station. The so called floor and ceiling are covered in instruments and control panels to save space. 

• Every month the ISS orbit decays by 2 KM, it must be topped up by rocket boosts regularly. 

• The European module is called Columbus and is used mostly to conduct experiments such as exposure to space tests using air locks and thethers. 

Stentor Cells

There is a giant single celled life form on Earth called Stentor. It is so big that it can be seen without a microscope. They often grow to about the size of a grain of rice and have been known to eat multi cellular organisms. 

Ice

At earth's atmospheric pressure 

Hydrogen freezes solid at -259.16 °c.

Oxygen freezes solid at -218.79 °c.

Nitrogen freezes solid at -210 °c 

Carbon Dioxide freezes solid at  -78.5 °c  

Helium won't freeze at any temperature in Earth's atmospheric pressure except absolute zero which is impossible. 

If you made a bowl out of frozen carbon dioxide, Helium, Hydrogen, Oxygen, and Nitrogen ice would boil in it. 

Oxygen ice is magnetic as is liquid oxygen. 

Your Ancestors

You came from 

2 parents,

4 Grand parents 

8 Great Grand parents 

16 Great Great Grand Parents 

32 Great Great Great Grand parents 

64 Great Great Great Great Grand parents 

This means you have 126 ancestors in 6 generations of your family. They are all likely to be very unique and different people. 

Night and Day

Night is the shadow of the Earth so when the Sun sets on the Horizon  you are seeing the Earth's shadow move towards you. 

The Earth isn't obiting the Sun, it is orbiting the solar system's center mass, most of the solar system's mass in in the Sun so we appear to be orbiting the sun but in reality the Sun and the planets are orbiting a point that is close to the Sun's surface. If you were looking at the sun from another star, it would appear to wobble because it is orbiting a point that is sometimes below it's surface and other times it is above the surface depending on where Jupiter is. 

Google Chromecast

The new google Chromecast is not just a video streamer. It comes with a remote control and has its own fully functioning Google operating system called Google TV that allows you to put your own apps on it. 

If it was released in the 90s it would be considered a super computer. Yet it costs just over £50 and is powered by the 15 watts 12v usb cable that can be connected to a TV. 

It is a system on a chip (soc). This means they made a micro processor that does everything, it processes video, data and sound. They made an all encompassing microprocessor that does all the work of an entire desktop computer. 

At also has Bluetooth so you can connect an input device to it like a Bluetooth keyboard & Mouse. 

The Chromecast itself can fit inside the palm of your hand.
