Minerals

Quartz, Basalt, Biotite, Marble, Apatite, Fluorite, Granite, Calcite, Galena! What are they? They are minerals, that naturally occur, are inorganic, are solid, have a crystalline structure and definite chemical composition. What does that even mean?

It means:

• Naturally occurring = MADE IN NATURE

• Inorganic = NOT LIVING

• Solid = NOT A LIQUID OR A GAS

• Crystalline structure = A UNIQUE ARRANGEMENT OF ATOMS

• Definite chemical formula = ALWAYS MADE UP OF THE SAME ELEMENTS

What about Coal? Is, Coal a Mineral. No!, because it is made from the remains of LIVING things, it is not inorganic. But, what about Halite (Salt), is that a mineral. Yes!, it checks all the five points.

How do you Identify a Mineral?

All the minerals have physical properties. The main physical properties are:

  • COLOR: It is not a best way to identify minerals because gravity, air, and water can change the color. Also, some minerals are same colors.
  • LUSTER: It is the way the surface reflects light. There are three types Metallic which is bright and reflective, Sub metallic which is dull, reflective and Nonmetallic which is anything not in the other categories.
  • STREAK: Color of a mineral’s powdered form, is obtained by rubbing the mineral against a streak plate (Unglazed porcelain).
  • CLEAVAGE OR FRACTURE: The way a mineral breaks. CLEAVAGE is a breakage along smooth, flat surface. FRACTURE is breakage unevenly along curved or irregular surfaces.
  • HARDNESS: Mineral’s resistance to being scratched; use Moh’s hardness scale to test hardness. 1 is the softest while 10 is the hardest.

There are also Special Properties:

  • FLUORESCENCE: Ability to glow under an ultraviolet light.
  • MAGNETISM: Minerals that are natural magnets.
  • CHEMICAL REACTIONS: Minerals will bubble or fizz when in contact with a weak acid.
  • TASTE: Some minerals have a specific taste. For example- Halite has a salty taste.

Why should you not wear uniforms?

Have you ever been in school with same clothes every day? School uniforms are the reason why everyone looks the same. I think schools should not have school uniforms.

In my opinion school uniforms don’t give options or choices. For example, You may argue that school uniforms don’t allow you to express yourself. I would say uniforms are bland and don’t allow us to choose from a variety.

Another reason is uniforms promote outdated gender. For example, all girls don’t want with skirts boost don’t want to wear shorts. Students need to wear clothes that are comfortable to them, to help them study properly. They might feel this clothes are too tight, or too short, or too droopy. They need to choose what they like to wear.  

Finally, students need to be individual. For example, You get lumped in with the rest of your classmates or friends in uniforms. Students need to express themselves in a unique way not everyone looking the same.

Overall, that’s why I think you should not wear uniform.

Should Truman Have drop an atomic bomb on Japan

Was Truman right to do what he did? Did he make the right choice? I think Truman made the right choice of dropping the atomic bomb on Japan.

In my opinion Truman made the right choice because it saved a lot of American lives. According to the text “ In his 1955 memoirs, Truman strongly believes dropping the bomb saved half a million American lives.  ”. Dropping the atomic bomb was the best thing to do instead of risking a lot of American lives.

Another reason is that Japan attacked the Pearl Harbor an American Naval Base on the island of Oahu, Hawaii, west of Honolulu. The text says, “ In the surprise attack, Japan sunk several ships, destroyed hundreds of planes and ended thousands of lives. The Japanese goal was to cripple the U.S. Pacific fleet, and they nearly succeeded. ”.  Think if they attacked are naval base, then we need to attack theirs in Hiroshima to take revenge.

Finally, Germany surrendered on May 7 and in the east on May 9, 1945 to America and its Allies France, Great Britain, the Soviet Union or now called Russia. But Germany’s Allie Japan did not wan to surrender. So, Truman thought of something really destructive to destroy everything & end World War 2. According to the texts “  At 8:15 am Hiroshima time, “Little Boy” was dropped. The result was approximately 80,000 deaths in just the first few minutes. Thousands died later from radiation sickness. On August 9, 1945, another bomber was in route to Japan, only this time they were heading for Nagasaki with “Fat Man,” another atomic bomb. After the first minute of dropping “Fat Man,” 39,000 men, women and children were killed. 25,000 more were injured. Both cities were leveled from the bombs and this, in turn, forced Japan to surrender to the United States.“

As you can see, Truman made the right choice of dropping the atomic bomb on Hiroshima and Nagasaki cites in Japan. Overall, that’s why I think, Truman made the right choice of dropping the atomic bomb.
