What is the mineral property called 'hardiness'? (Mr. Giraldi)

# data[].attributes.body
This is an example question, so that my Grade 4 students can see what's expected of them!

Answer
My question was all about the mineral property called 'hardiness'. Hardiness means how hard a mineral actually is. Talc is the softest mineral, and diamond is the hardest! Minerals are judged on a hardiness scale from 1 to 10 (with 10 being the hardest, and 1 being the softest). Only a harder mineral can scratch a mineral below it on the hardiness scale! For example, Corundum is rated at a 9 on the hardest scale. That means only diamonds (rated at a 10) can scratch them!

We use Transport in minerals like the car door,  magnetite and  hematite are like little magnets, they put those minerals in the car door and when you close the car door, those 2 minerals work together and stick. Steel and iron are both minerals and are both used for making cars Iron is used to make hard,strong and rigid steel. Chromium is used to coat Bumpers, badges, and door handles to prevent them rusting.  chromium comes from the mineral chromite.  Two metals, aluminium and titanium, are used a lot in airplanes because they are lightweight and strong. Aluminium comes from a material called bauxite. Titanium comes from minerals called rutile and ilmenite. Gold is used in electronics. It conducts electricity very well and is very flexible, twisting easily into fine wires. It is used to make electronic circuit boards and other components.  Mica is also used in electronics. Muscovite mica is used to make electrical capacitors and high temperature insulators.

There are a lot of different verities of purple minerals.Some purple minerals are Amethyst, Quartz, Fluorite, Lepidolite, Charoite.
Why are minerals different colours?
Minerals are different colours because of the imperfections and impurities but some minerals stay the same colours.For example, Quartz comes in purple but also comes in other colours such as white, pink, brown, blue, black, and many many more, but Charorite is always purple. So don't always rely on the colour of the mineral to find out what the mineral is!

WHY ARE MINERALS DIFFERENT COLORS? (ZAINAB)

# data[].attributes.body
Minerals are all different colors. They get their color from slight imperfections or impurities a mineral may carry. Good examples are azurite and malachite, which have their strong blue and green color due to their copper structure.Some people use colors to identify minerals, but don’t get fooled! Some rocks of the same type can be different colors.

TYPES OF YELLOW MINERALS?

Gold, anglesite, barite, smoky quartz, citrine, heliodor beryl, scapolite, pyrite, scheelite and andalusite.

Minerals are sometimes found as well formed crystals. The shape of these crystals can often be used to identify minerals.Every crystals is a solid shape. A crystal could be any shape. Like a rectangle,  square, triangle or hexagon. Gold sometimes crystallizes   into perfect cubes.Quartz is the top part of a crystal that is the part that is pointed on the crystal. If you sliced the quartz of the crystal there would be the shape of a hexagon.

Lustre is a describing word for a mineral.

It can be used to identify minerals.

There are 7 different types of minerals.there are two main types of luster.

1.Vitreous (glassy) you can see your reflection.

2.metallic (A dark metal colour).

An example of a vitreous rock is quartz,and an example of a metallic rock is sphalerite.

cutlery;
What do you see when you go in the kitchen forks,knifes, spoons and other stuff that are made by steel is a mineral .Iron and chromium both come from minerals and makes steel .

crockery;
plates , cups and bolas are made by clay minerals. clay is made by minerals . and clay plates keep your food warm.

Cans and tins;
Cans for drinks come from a material called bauxite .

Have you ever had a plaster cast?plaster is made out of a mineral called gypsum.It's easy to shape when it's wet,that's how docters shape casts.Thermometers contain mercury that comes from   an ore called cinnabar.it's metal, but at room temperature it's liquid!it expands at body temperature.Dentists use mercury too!The fillings you get are made of amalgam.Gold is used to fill in cavities.They use gold because it's strong.

Fluorite can be many be many different colors in the minerals. The different colors are caused by a slight imperfection mixed together a mineral may contain. To identify many different minerals you should look at more than just there color. But some minerals are always the same color some are are always the same color because  of two copper minerals, Malachite and azurite. Some minerals are always the same color because, malachite is always green azurite is always blue. The azurite has a strong blue and and the green color is due to there copper.

Most orange minerals are made of iron. Did you know that if you leave a lump of iron in the rain it will start to turn rusty . Did you know that Quarts can be orange.When iron is rusty it starts too turn orange brown. Other minerals can be orange like zircon and diamonds.

Ruby is the red form of corundum.  Ruby minerals are red because it has because the slight imperfection of impurities. Chromium is a metallic element that humans also need..

Hematite is a mineral that is red and a bit brown.
Hematite is an iron ore mineral.
Fire opals are orange and red.
Cinnabar are also a red mineral they beryl.
beryl is classified as an alkaline
earth metal which are located
in elements of the  periodic table .Beryl is also an element.

Minerals are naturally occurring.
They are not made by humans.
minerals never been alive and are not made up from plants or animals.each one is made of a particular  mix of chemical elements. They are not liquids (like water), or gases (like the air around you). The chemical elements that make up each mineral are arranged in a particular way - this is why minerals 'grow' as crystals.

Some minerals have different colours. There is a mineral called beryl and there are different varieties of beryl such as gemstone and emerald. Tiny amounts of metal chromium is what causes the intense colour in emeralds. Traces of iron,on the other hand,can cause beryl to have a beautiful blue-green colour. Datolite,pyromorphite and some opals have different shades of green.

Lustre is a mineral that is reflected by light and when you see other stones and mineral they will reflect in a different way.Sometimes we can identify minerals.A diamond crystal has a brilliant shiny adamant lustre. When you put lustre near a glass they will both reflect the light that's shining at it ,if you put it near metal it will still shine.The two main lustre minerals are metallic and nonmetallic, there are several other subtype of nonmetallic  such as vitreous, resinous, pearly, greasy, silky, adamantine, dull and waxy.
adamantine minerals is a superlative lustre, which is can seen in diamond , these kind of minerals are transparent or crystal clear , thats why adamantine lustre are uncommon.

What Does Lustre Look Like?
Lustre is made out of mineral  and it looks like  glass or shining stone and rocks because and it shines like light . following are some example and their  stats
Metallic has  very high reflection ,
Submetallic  has a  medium reflection
Adamantine: very high transparent solid stone .

Minerals are like cakes because they're both solids so there not liquid or gases.Cakes are like minerals because they need ingredients to    make it.If  you make a cake without  flour it will be soggy minerals need the chemicals to make the mineral form properly.Cakes are not like

minerals because we make cakes we do not make minerals they

form when lava cools on the ground and  it becomes minerals.Cakes  are not like minerals because cakes use organic ingredients like  eggs but minerals are inorganic.

There many minerals around the house.The out side of their house is made out of bricks and cement, which  are made out of clay. Clay is made from limestone and other minerals.  Inside  the house, the walls are made from plasterboard,which is made out of another mineral called gypsum. It is formed with water and heated to make the boards . The house also has windows made from glass.  The glass is created from quartz and sand  which is heated to a high temperature.  The house may fall apart without an important items such as nails and screws.  These items are made from steel which comes from iron, which is very common in the earth.  Also around the house there are other minerals like copper which used for pipes. So there are many minerals which are used to build a house  .
