Earth and Us
Earth and Us
Our love for the planet is the whole purpose of this workshop. In the world today children are being told about global warming, climate change and land fills! We have built a workshop to help them understand what all of this is about. The children are taught how the Earth formed in its early days to surviving the day to day journey through space dodging asteroids and staying within a nice toastie distance from the Sun. Join us on a voyage of fun, science and discovery to find out how this big rock of ours works and how we can keep it the brilliant place it is!
This Workshop is for years 3 and 4 and will count towards the Eco part of their curriculum, they will learn all about recycling and be left with certificates to fill in that enable them to start making a difference in their local area.
The Earth and the Moon once crashed into each other many, many moons ago! Ha, but when the Earth was first forming the orbits, the big lumps of rock that were quite happily forming got a tad close and Boom! they rocketed into each other! They then went spinning off from each other and if that had not have happened then (for one surfers would have nothing to ride at the beach!) we would not spin at the right speed to have steadied out and Earth would not have had a chance to slow down and start forming everything.
Thanks Moon, but please do stick around! (it is drifting away really really slowly and in a few billion years it won't be close enough to help us stay steady. We may gain a small wobble.)
So... Earth, we walk on it everyday. Have you ever stopped to think about how much is actually packed on it?! Beaches, Oceans, Forest's, Ice, it is just packed! But, why?
It is all to do with spin distance and such, so it works like this... Sun rays fire at the Earth from 92.96 million miles which is really handy as if we were a tad closer we would burn up and a few the other way, well it would be a tad chilly. So, rays fly at us but because of the angle of the Earth it lets in more sunlight across the equator than say... Great Britain which does get sunny days but nowhere near what say... Africa gets, basically because it is at less of an angle so more sunlight gets through! And the big reason it stays really chilly at the poles is because of the same reason cricketers wear white, it reflects sunlight! so the sun gets through to the poles and bounces straight back out again... It doesn't get the chance to heat up. So how can global warming be happening if all the heat bounces off the ice? Well this is how we understand it...
