MooMooMath and Science: Mineral Identification Tests

Introduction

• The video is focused on identifying minerals through various tests.
• Tests include examining color, hardness, streak, magnetism, and reaction to acid.

Mineral Identification Tests

1. Color Test

• Initial observation of the mineral's color.

2. Hardness Test

• Tools used: fingernail, penny, nail, glass.
• Scale of hardness determined by which tool can scratch the mineral.

3. Streak Test

• Involves using a streak plate to observe the color of the mineral's powder.

4. Magnetism Test

• Check if the mineral is magnetic.

5. Acid Reaction Test

• Use a mild acid (vinegar) to see if there's a reaction (fizzing).
