Facts About Thames Barrier

The Thames Barrier which was built in 1984, protects Central London from tidal surges in the North Sea. It protects 125 sq km or 48 sqm of Central London. The Thames barrier was built, because of the Thames flood in 1928. The Thames river flooding destroyed lots of properties and 14 people lost their lives in the flood. So, the Environmental Agency came up with the idea of the Thames Barrier and its construction started in 1974. It is predicted that even with heavy rainfall and rising tides due to climate change it will still be able to protect London from flooding until 2070. There are three positions of the Thames Barrier to let the river water flow in a controlled amount. 1- The "Underspill position", of the barrier allows a controlled amount of water to go under the barrier, this position is used when tides get too

Lunar Eclipse 2018 - Fun Facts

On 27 July 2018, there will be a longest total lunar eclipse , during which the moon appear a lot bigger and also red.And the eclipse can be seen for the whole one hour.

If the moon keeps on going round and round the earth then we should get a lunar eclipse every month.Instead , we get a lunar eclipse once every year.Why

The event organizers registered and provided all the participants with a shirt and a lanyard with our name and projects name on them.Then, I was allocated to a table with my name and my project name on.Next to me, was a team of children that had made a Zombie Apocalypse project. My Presentation Table and Ninja Shirt There were four categories which included web pages, scratch, hardware and mobile applications.Many children took part in those categories.There were four brilliant Science Shows, I had the chance to attend two of them, hosted by Greg Foot and Neil Monteiro, who were the Science presenters. I also got to see 3D printers, speech to text machines and a camera
