Mind Blowing Fact About Atoms!

This is an image of the Atlantic ocean which is huge. Now in your head imagine it being measured in teaspoons. That would be a very big number. Did you know that one teaspoon of water has more atoms than there are teaspoons in the Atlantic ocean? In one teaspoon there are 200,000,000,000,000,000,000,000 water molecules, and each of these is made of three atoms. If you lined all of these atoms end to end you would get 50 billion km which is 10 times the width of our solar system.

This guys name is Daren Rahlves.  By skiing down this slope he starts an avalanche.  This video is shot in Alaska .  Because he has an airbag, it saves his life.  An avalanche is a mass of snow, ice and rocks falling rapidly down a mountainside.  As it gets near the bottom, its gains speed and power. This moving snow can go more than 80 mph. Avalanches kill more than 150 people in a year so the airbag really did save this guys life.

My dad is from New Zealand. New Zealand is located in the Southern hemisphere of the earth. On Wednesday many people who live in Christchurch, New Zealand got to see the Southern lights or aurora australis. Some call it a solar storm. This is similar to the northern lights where the sky is lit up with different colors. 

What causes the colors in the sky is due to fast moving electrons striking atoms in the earths upper atmosphere... which is mainly Nitrogen and Oxygen. These electrons come from the sun which the earths magnetic field protects us from. Sometimes these electrons make it down towards the earths Northern and Southern poles and through its atmosphere and that's when the electrons collide with Nitrogen and Oxygen. This puts the atoms in an excited state.  While they get back to their regular state they should be in, excess energy is released in the form of visible protons.

A Beautiful, Beautiful World

This song, called "A Beautiful, Beautiful World" talks about how the world is 25,000 miles around and how its geography is diverse. It also talks about how earth orbits the sun and the moon orbits earth. If the earth was any closer or farther to/than the sun, we would not be able to live on it because it would either be too hot or too cold to live on. The earth is 92,960,000 miles from the sun, which is also 149,600,000 kilometers. The hottest it has every been on earth is 136° Fahrenheit, and the coldest it's ever been is -128.6° Fahrenheit.

Robo Bird

In Germany, Dr. Heinrich made what he calls a Robobird or smart bird. There is a lot of technology inside this man made bird.  Real birds wings are very complicated.  There are several joints in a birds wings that allow the wings to bend and flex.

RAINBOWS

Rainbows appear when water droplets break sunlight into the seven colors of the light spectrum.
The sun is always behind you when you look at a rainbow, and the rain is always in front of you. 
Most people believe that rainbows are only seven colors- red, orange, yellow, green, blue, indigo, and violet. Actually, this isn't true. There are continual colors of the rainbow, some of which even our eyes can't see.
What makes a double rainbow? Well, think about a normal rainbow. That's made by sunlight reflecting the colors of the light spectrum. Double rainbows are just like that, only the colors are reflected twice instead of once.
Rainbows occur more in summer than in winter (for most places) because in order to have a rainbow, there must be rain and sunshine, but in the winter, the water droplets are too cold and freeze, and the clouds usually block the sunshine.
Rainbows are so rarely seen at noon because rainbows are always opposite the sun, and so at noon, the rainbow would be below the viewer.
Did you know that, if the moon's light is bright enough, it can create a rainbow as well as the sun? Well, it can. This is called a lunar rainbow. It is made by the same process as a normal rainbow, only with the moon.

Law of physics

You tube

This is a video showing someone dropping a watermelon and an egg.  One might think that the watermelon would drop faster because it's heavier.  Others might think that the egg would drop faster because it's more streamlined.  But Galileo proved that in the law of physics, all objects fall the same.  He proved that gravity accelerates all things equally no matter what their weight.
