Andre så?
Jeg er helt ved at gå i spåner over det nu, for sidder med en del små ting jeg ikke rigtig kan finde ud af /: Og jeg skál afleverer imorgen.. Altså ALT hjælp ville kunne gøredet hele lidt bedre. Kan sende raporten som fylder ca 2 sider, og hvis i bare gad rette stavefejl/dummefejl, eller hjælpe med en opg eller to, ville det være mig til stor stor hjælp.
På forhånd tusind tak !

Okay Jeg sætter den ind (: !
Sætnigner eller ord med [] om er noget jeg ikke kan finde ud af. Hvis jeg har undladt noget vigtigt , vil jeg meget indberettes om dette (:
1. Purpose
Why did we do this exercise? What did we want to find out?
Ved ikke hvad jeg skal skrive her. Nogle ideér? Har nogle her underneden. Kan de bruges ?
Connection between minerals and rocks.
History.
Power of nature.
How to use it. (rocks today).
2. Observation/description
The observations are as a description of each stone. A list of facts is not enough!!! This is not the place to write the determined names of the stones, this belongs in the conclusion.
Hint: give each stone a number that make it easier to make the conclusion.
Stone 01. This rock have an irregular shape and different colours such as grey, white and dark purple. It is a crystal and the material is very hard. [Mineral-more than one?]
Stone 02. This rock is much grained and has an irregular shape. It is a very hard stone and it is a mix between different minerals. This stone is red, grey, black and a little white.
Stone 03. This rock is rounded and almost pure white (just a little grey init). Compared with the other stones this one is softer and contains no visible crystals. It is a mineral [(more than one?)].
Stone 04. This rock is grey, blue and black and has got some chalk on the outside. It is a little rounded, has no visible crystals and [(does not contain minerals)].
Stone 05. This rock is gold coloured and is very glittery. It is medium hard, contains mineral [(more than one?)], has an irregular shape and has a crystal-look.
Stone 06. This rock is composed mainly of sand corn-size minerals or rock grains. It is red and grey and striped and has an irregular shape.
Stone 07. This rock is dark brown and consists of large-grained crystals. Is rounded and is a hard stone. ?
Stone 08. This rock is black and not very hard. Contains minerals, has an irregular shape, is flat and homogeneous.
Stone 09. This rock is just like stone number 6 just smaller and with fewer stripes. But it is the same kind of stone.
Stone 10. This rock is a mineral and is salmon pink in colour. Have an irregular shape and a [(hardness? –Medium hard?)] visible crystals-don’t think?
Stone 11. This rock is just like stone number 3 just smaller. But it is the same kind of stone.
3. Theory
Describe the theory of minerals and rocks
A mineral is an inorganic solid, which has a definite chemical composition. It occurs naturally, and with atoms arranged in an orderly pattern. Most minerals are compounds (ect. Quartz, witch is a compound between silicon and oxygen). Minerals consisting of single elements are called native elements (ect. Cupper (Cu)). When different types of minerals are found mixed together (compounds and native elements), it is called rocks.
Examples of the processes are plate tectonics vulcanism, earthquakes, deposition and erosion and through the break down of the mountain ranges.
Rocks are found in Earth’s crust and mantle. Those stones of the mantle are mainly similar and are not often seen at the surface. Crust contains of many different types of minerals. These rocks can be classified according to the processes by which they are produced:
A) Sedimentary rocks (deposited rocks): are for example chalk, shales and sandstones. They are formed by sand, limestone or clay, which has been deposited in a particular geological [environment]. Over the time the material has been compacted to structure a hard rock by overlaying layers of rocks and sediments.
B) Magmatic rocks (vulcanic rocks): are for example basalts, granites and pophories. They are produced by crystallisation of melted rocks (melted by volcanic activity and from heat in the inside centre of Earth.).
C) Metamorphic rocks (Altered rocks): are for example quartsites (sandstones), marbles (limestone) and gnejses. Through the breakdown of the mountain range the rocks have become warm and soft devoid of melting, and have in this manner transformed form and shape. The different mineral grains are often found as stripes in the rocks.
4. Discussion
This is the part where you present your arguments for naming and classifying the stone in the way you have.
Stone 01) This kind of stone is called an amethyst and is [classifying as a?]. It is one of the most ordinary minerals in Earth’s continental outer layer. It is made o trigonal silica (silicon dioxide, SiO2). Haves a density of 2.65g/cm³ and a hardness of 7.
Stone 02) This kind of stone is called granite and is classified as a magmatic rock. The name granite comes from Latin Granum, and means corn, which attribute to it’s grained structure. It is a hard stone with a hardness between 5.5 and 7, and a density between 1.74 g/cm³ and 2.98 g/cm³ (typical 2.75 g/cm³)
Stone 03) This kind of stone is called chalk and is classified as a sedimentary rock. The chemical compound of chalk is the following: CaCO3 or potassium carbonate. [Density and hardness?]
Stone 04) This kind of stone is called flint. It is a hard [(hardness?)], sedimentary crystalline silicate form of the mineral quartz, categorized as a variety of chalcedony. Generally there is chalk on the outside of a stone like this. It haves a density of approximately 2.75 g/cm3.
Stone 05) This stone is called pyrite (also known as fool's gold) and is a mineral [classified as a?]. It has isometric crystals that usually appear as cubes. The chemical compound of pyrite is the following: FeS2 or iron disulfide. [Density?] and a hardness of 6/6.5.
Stone 06) This stone is called sandstone and is classified as a sedimentary rock. It is mainly composed of sand-size mineral or rock grains, mostly of quartz and/or feldspar because these are the most common minerals in the earth's crust. [Hardness and density?]
Stone 07) This stone is called Rhomb porphyry and is classified as a magmatic rock consisting of large-grained crystals, such as feldspar or quartz. The term "porphyry" is from Latin and means "purple", which in old time was the color of royalty, and the "Imperial Porphyry" was a deep brownish/purple igneous rock with large crystals of plagioclase (a very important series of minerals within the feldspar family.). [Hardness and density?]
Stone 08) This stone is called biotite and is [classified as a]. The chemical compound of biorite is the following: K(Mg, Fe++)3AlSi3O10(F, OH)2. It haves a hardness of 2.5 – 3 and a density of 3.09 g/cm³
Stone 09) This stone is called sandstone, which is the same as stone nr. 6.
Stone 10) This stone is called feldspar and is classified as a ?. It contains of rock-forming minerals which make up perhaps as much as 60% of the Earth's crust. [Hardness and density?]
Stone 11) This stone is called chalk, which is the same as stone nr. 3.
