Esperamos que hayáis descansado y
disfrutado muchísimo de estas vacaciones.
Como ya sabéis, debido a las
intensas nevadas de estos días, hoy y mañana no podemos ir al colegio pero os pondremos las
actividades que tenéis que realizar aquí en el blog.
Las actividades de hoy de lengua y
matemáticas serán realizar las portadas en vuestros cuadernos de las nuevas unidades
y copiar lo que vamos a aprender en ellas. Os lo dejamos a continuación:
We hope you have enjoyed your Christmas holiday and you are ready to start this new term! For the moment, we will have to wait two more days to see each other but...there are things we should do!
For Monday you will have to complete this worksheet about your holiday. If you cannot print it...do not worry! you can copy it on a piece of paper and do it there.
Have you ever asked yourself what is underneath the ground you walk on every day? The solid part of the Earth is called the geosphere and it is made up of different layers:
The lithosphere is the solid outer part of the geosphere, including the crust and top part of the mantle.
The lithosphere is made up of rocks. These are solid materials which form naturally. Rocks are made up of minerals. Some rocks are made up of different minerals and others are made up of only one material.
We can classify rocks into three main groups:
SEDIMENTARY ROCKS
IGNEOUS ROCKS
METAMORPHIC ROCKS
Sedimentary rocks are formed by sediments that are carried by rivers and settle at the bottom of lakes , seas or oceans. The sediments are compressed over millions of year. They solidify and become rocks.
LIMESTONE
SHALE
Fossils are commonly found in sedimentary rocks.
Igneous rocks are formed by the magma in the Earth´s mantle. When magma comes to the surface through volcanic eruptions, it cools and forms igneous rocks.
BASALT
GRANITE
Metamorphic rocks are originally sedimentary or igneous rocks. These rocks are transformed over time by intense heat and pressure below the Earth´s surface.
MARBLE
QUARTZITE
Watch the video below:
MINERALS are solid substances which form naturally. They are some of the most beautiful things on our planet. They are also some of the most useful things. Minerals are used to make things like computers, smartphones, light bulbs and even the path outside your house.
We cna classify mineral by their characteristics: colour, lustre (shininess), cleavage and fracture, and hardness.
AZURITE
QUARTZ
JADE
MICA
Hope you have learnt lots of things about minerals and rocks.
