Summary:

This week we were learning about minerals. Each person chose a mineral that they wanted to learn about, and then they started researching about it. After that, we put our research into a magazine. We used jilster. The mineral that I chose was Miargyrite. What is that? Read on to find out...

 First we should check if miargyrite is even a mineral. Do you remember what it takes to be a mineral? Do you remember what each part means? We'll go over it.

 The first characteristic that it takes to be a mineral is naturally occurring (not made by humans.) Is miargyrite naturally occurring? Yes. It is formed in nature. It is not really known how miargyrite is formed, but we know that it is naturally occurring.

 The next fact we should check on is, is miargyrite inorganic? (Not alive.) We know that Miargyrite is not alive because it is not made up from plants or animals. It does not need food to survive. 

 The third feature that it needs is to be is a solid. (Does not take the shape of its container, and has a definite shape.) Miargyrite is definitely a solid because it does not take the shape of its container, and it has a shape that it always is in. 

 The next facts are that it needs to have a definite chemical composition and atomic arrangement. The chemical elements that make up the mineral should be arranged in a certain way. Researchers found out that the chemical formula of this mineral is AgSbS2. 

So... what do  you think? Is miargyrite a mineral? It passed 5/5 on the test, so that means it is a mineral. Here is a link to a website about miargyrite:

Information:

Now that we know that miargyrite is a mineral, it is time for some interesting information about this mineral. Do you know where you can find it? Do you know what it looks like? You will find out soon.

Description:


Miargyrite is a silver sulfide mineral. Some other minerals in this family include pyrargyrite, polybasite, proustite, argyrodite, andorite, and more. Some people confuse miargyrite with these minerals.

Physical Characteristics:


The color of miargyrite is iron black to steel gray. The luster is metallic. Luster is the way it looks when light shines on it. The transparency is opaque. Opaque means not able to be seen through. The density is 5.19. The hardness is 2-2.5. This means that it can be scratched by anything that has a hardness higher than 2 or 2.5. (depending on the type.) This means that it is pretty soft. The streak is cherry-red. (What it looks like when it is in powdered form.)

Where can it be found?



Miargyrite can be found in Europe: Saxony, the Harz Mountain of Germany; Přibram, Czech Republic, Romania; Scientists also found it in South America: Chile and Bolivia; If you want to find in the USA, it rarely shows up in Idaho, Colorado, Arizona & California.

Interesting Facts:


  • Miargyrite is a very uncommon mineral. 
  • It is named after the Greek word Meion which means “less”, and Argyros which means “silver". This is because it contains a lower amount of silver than other silver ores.
  • This type of rock is a sedimentary rock. (made out of sediments.)

Conclusion:

I hope that you have learned a lot about miargyrite; or as greeks call it... "the lower amount of silver" from reading my blog. I am going to the Czech Republic soon, and I hope I can go to Přibram to find some miargyrite!

SP6: Constructing explanations and designing solutions:

I constructed an explanation of what miargyrite was when I was researching facts about it. It was difficult to find information about miargyrite because it is so uncommon, but as you can see I have managed to get quite a lot of data.

Structure of the Periodic Table - 9/25-9/29

https://image.slidesharecdn.com/theperiodictable-110223090122-phpapp01/95/the-periodic-table-7-728.jpg?cb=1298451775 Summary: This week, we have been learning about how the periodic table is arranged and the different patterns that are in the rows  and columns. In the periodic table, the rows are called periods. Along the rows, the elements are organized by atomic number (the number of protons.) The rows also have the same energy level or the number of electrons. For example, in the first row, all of the elements' atoms have one energy level, and so on.The atomic mass is the number of neutrons plus the number of protons. The atomic mass can be a decimal, and it is ordered increasingly. The columns in the periodic table are called groups or families. Each family has a name. For example, group one is composed of alkali metals which is the family with Lithium, Sodium, and more. Each group also has the same number of outer, or valence electrons. The elements in group one ...

Musical Instruments and Sound- Weekly Blog (3/11-3/15)

Sound Energy - Musical Instruments by SolPass Summary We understand how sound is produced, and how sound waves can travel through different mediums, but how do musical instruments produce sound? There are hundreds of instruments in the world, producing various pitches, tones, and chords. There are three main types of instruments: wind, percussion, and string. The sound is produced differently based on the type of instrument. The first type of instrument is a string instrument. In a string instrument, the sound is created from the vibration of strings. For example, when you play guitar, you pull on the strings. As the strings vibrate, the air molecules start vibrating as well, producing sound. The next type of instruments are wind and brass instruments and are made when we blow sound into them. The shape and position of the instrument affect the overall tone and pitch. The most common kind of wind instrument is a reed instrument. Blowing on the reed causes it to vib...

Energy Transformations - Weekly Blog (1/28-2/1)

Types of Energy  by  Solar Schools Summary: You've probably heard the quote by Albert Einstein, "Energy cannot be created or destroyed, it can only be changed from one form to another." But what are the forms of energy? There are six general energy forms: chemical, mechanical, thermal, light, electrical, and nuclear. Any form of energy can be converted into another form. There are many examples of energy transformations that happen in our everyday lives. The first energy form is chemical energy. Chemical energy is a form of potential energy and is stored in chemical substances. An example of chemical energy is gasoline that is used to power a car. The next form of energy is mechanical energy. Mechanical energy is energy released by a moving object. For example, mechanical energy is the energy that causes a soccer ball to move when kicked. Another form of energy is thermal energy and is associated with the motion of molecules. This means that it is caused by f...
