MINERAL ID: A VIRTUAL LAB REPORT
Lab Title: Identification test of the minerals
Background: Minerals is a non-living solid all minerals are formed from natural
processes occurring on the surface or within the earth without any human
interference, if a mineral is not made naturally if is made by human is not
considered as a mineral. Rocks are made of minerals some of them are made by
more than one mineral. Every mineral is broke in cleavage or fracture.
400 minerals found. All minerals
are naturally. Minerals are organic and non organic. They are everywhere on
earth in different conditions. Some of minerals known as carbonates made in
warm, shallow ocean waters. Other minerals made when rocks changes in pressure
or temperature. There are four major processes which minerals made:
crystallization from magma, precipitation, changes in pressure and temperature,
and formation from hydrothermal solution.
Minerals properties when
minerals have there own thing what thing minerals have, for example color.
Height, weight etc. some minerals can be organized by other different
properties. Metallic minerals such as gold, silver, and copper, are easily
shaped. Some types of magnetic are magnetic and can used to pick up paper clip
and small nails. A minerals properties elements depend on the element that
compose the minerals.
Purpose: The
purpose of this lab is to describe the characteristic of some minerals to find
the type of minerals that they are. We did this activity to learn more about
minerals. In this lab we were supposed to learn more about minerals and the
steps that we have to take order to describe a mineral.
Materials: Streak
plate, glass plate, penny, nail, fingernail, magnet, camera, minerals and
magnifying glass.
Problem:
To identify minerals using their physical properties and to get
acquainted to a set of common, rock-forming minerals.
Methods/Procedure:
(you will need more steps than 3)
Step 1 – We tested
for streak to find the color.
Step 2 – We did the
hardness.
Step 3 – We did the
cleavage.
Step 4- We did the
luster to find if the minerals were metallic or nonmetallic.
Step 5- We use a
magnet to see if the minerals were magnetic.

Results: A= Muscovite Mica, B= Talc, C= Quartz, D=
Hematite, E= Potassium Feldspar.
Discussion/Analysis: I get 4 out 5 minerals correct;
the one that I get wrong was because I made a mistake doing the hardness.
Conclusions: I learned that by predicting the mineral
using the chart I can get the definition that can tell me which one is that
mineral, but is not accurate as testing it.
BE SURE TO HAVE THIS CHECKED BEFORE YOU PRINT!!
