Welcome to my web page! I have experimented on a lot of minerals, and I came out with a lot of facts and data. Please look below to see my data and results.

Introduction
A mineral is a natural, crytalline (when atoms have a repeated pattern) solid that is created by heat and pressure underground. The purpose of this project is to learn more about the physical properties of minerals. Understanding physical properties can help you learn about minerals. For example, you can identify unknown minerals by testing their physical properties. In this experiment, I tested some physical properties for 20 different minerals. After this test, I could find the identity of all of my samples.
Methods and Materials
The properties we tested were streak, specific gravity, hardness, color, and luster. The materials were a nail, a streak plate, a square of glass, a magnet, and a bottle of lemon juice (used as an acid). For more information about these physical properties click here.

Conclusion

During this experiment, I learned a lot about mineral facts, such as some of the physical properties like streak, specific gravity, and hardness. I learned how to keep a lab book and how experiments work. I thought that this experiment was fun, but long. The experiment worked out as planned.
