Hello, little geologists!

(No olvidéis que hoy es martes poético: click).

I want to share today some pictures I received some days ago. A lovely cactus by David Me. and a cute kitten by Hugo R. 

We have to continue with our rocks and minerals, but first let's see if you can identify the next rock (a lovely photo sent by Daniela). Igneous, sedimentary or metamorphic?

Some days ago we talked about minerals and rocks. These are some of the things we learned: 

- Minerals are solid, natural and inorganic substances.

- Rocks are formed from minerals.

- There are three big groups of rocks: igneous, sedimentary and metamorphic.

1. To go over those contents, try the next exercise

a) This type of rock comes from lava____________________

b) Sometimes these rocks contain fossils_________________

c) These rocks change with extreme heat and pressure_____

d) Granite belongs to this group________________________

e) Clay belongs to this type of rocks_____________________

f) This is the external layer of our planet________________

g) A change in rocks produced by heat and pressure_______

2. Use your book to tell me where the different types of rocks can be found. Label the picture.

3. Do you know the difference between lava and magma? Is it the same?

I'd like to introduce the new section: properties of minerals (PB 62). When we talk about the properties of minerals we are describing them. We talk about their colour, shape and hardness.

Have a look at the next word map. Next week we will do some activities about it. 

Hardness is one the properties: how hard a mineral is. In the next video you can see ten examples of minerals on the Mohs Scale, from the softest (talc) to the hardest (diamond). 

See you tomorrow ;)
