Mineral Luster and Testing Procedures

The video tutorial guides students through an activity on the luster of minerals. It begins with an introduction to the materials needed and preparation steps. Students are then instructed on how to conduct a luster test to classify minerals as metallic or nonmetallic. The video explains the differences between these luster types and provides examples. Students analyze and record their observations, compare results, and discuss the applicability of the luster test. The activity concludes with a cleanup and a reflection on the uses of rocks and minerals.

What materials are required for the mineral luster activity?

• Activity sheet 1, magnifiers, mineral specimens, steel nail

• Activity sheet 3, microscopes, mineral specimens, steel nail

• Activity sheet 2, magnifiers, mineral specimens, plastic nail

• Activity sheet 3, magnifiers, mineral specimens, steel nail

What is the purpose of using newspapers in the activity?

• To write notes on

• To cover the work area

• To clean the magnifiers

• To wrap the minerals

How is metallic luster defined?

• Reflection of light from many particles below the surface

• Reflection of light from the surface of an object

• Absorption of light by the surface of an object

• Transmission of light through the object

Which of the following items is an example of nonmetallic luster?

• A chain

• A nail

• A toaster

• A drinking glass

What should students do with mineral specimens 3, 5, 6, and 8?

• Use them to test for hardness

• Classify them by color

• Measure their weight

• Examine them to identify metallic luster

What is the main goal of the luster test?

• To determine the weight of minerals

• To classify minerals according to their luster

• To measure the size of minerals

• To identify the color of minerals

What should students do with their observations?

• Record them on activity sheet 3

• Keep them to themselves

• Share them with the teacher only

• Discuss them with other classes

Why can't the luster test be used to determine the mineral content of a rock?

• The mineral may be buried inside the rock

• The rock is too heavy to test

• The rock is too large to handle

• The rock is too colorful

What should students do after completing the luster test?

• Throw away the mineral specimens

• Return the specimens and magnifiers to the storage containers

• Leave the specimens on the table

• Mix the specimens with other materials

What additional resources are suggested for further learning?

• The Delta Science reader

• The school library

• Online videos

• Science magazines
