We have been studying magnetism and we have discovered that norhtern lights have a lot to do with this. But why do the norhtern lights happen? Well, as we have discovered, there is a solar wind. These winds send charged particles into space that travel at a very high speed and collide against the magnetosphere.
But sometimes the solar winds are very violent and explosions occur in the Sun (solar flares). It is with the solar flares when we see the norhtern lights, as these charged particles from the Sun collide with the gas atoms in the atmosphere. Each gas creates a different colour.

During the first term, the children in years 3, 5, and 6 have been working on dinosaurs and have learnt lots of things. They have learnt so much, that they could become paleontologists. According to the fossils they could find, they are able to reach a conclusion. Here is a prove of it!
'This dinosaur is a plant-eater because the coprolite has rests of a plant, the teeth are from a plant-eater because they are square, and the egg is round. The toothmarks on the
feet and the claws under the earth indicate that a carnivorous dinosaur attacked him.The dinosaur had a shell, so it is ornithiscia, more especifically a Thyreophora.'
Nacho Garrido
'The tooth indicates that
this dinosaur is a meat-eater because it has a sharp
tooth. The dinosaur left foot prints
and they indicate
that this dinosaur
had 2 legs and
3 fingers so it is a theropod . I
found the skeleton of the dinosaur
and it is
a lizard hipped
dinosaur so it
is classified as saurischia . The coprolaite intains
traces of meat
this indicates that
this dinosaur is meat-eater
and I found
the eggs of
the dinosaur; this
indicates that this
dinosaur was a
famele , the size of the
egg is big
and it is
oval this indicates
the size of
the dinosaur is big
and meat-eater.'
