While out on a hike, you find an unknown mineral. how would you test the mineral to find out what it is?

There are 10 steps to help identify the rock/mineral...

Step 1: Pick Your Mineral/rock and clean off any debris or dirt ...

Step 2: Hardness. Kit of Mohs' Hardness Mineral Identification. ...

Step 3: Luster. Luster describes the way light reflects off of the surface of the mineral. ...

Step 4: Color. ...

Step 5: Streak. ...use streak plate, sidewalk, broken kitchen tile even and scratch rock against it

Step 6: Crystal Form and Mineral Habit. ...

Step 7: Cleavage and Fracture. ...how the rock breaks, smooth edges or jagged rigid edges where breaks and fractures are

Step 8: Magnetism. Use a front magnet or even a needle compass to see if rock has any magnetic pull to it.

Step 9: Any other identifying factors such as taste, fizz, heft. You can test fizz by dropping the rock in any acidic type substance. Vinegar is 1 of the safest liquids to use to observe if it had any fizzing. Heft is just checking how the density feels by holding the rock in your hand, does it feel heavier than it looks or is it extremely lighter than you would have guessed when holding it?

Step 10: Final Step is looking up all of these things you took notes on above and figuring out which category your rock/mineral fits best under and you have your answer :-)

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
