The way a mineral naturally breaks is called its cleavage. The number and orientation of cleavages can help identify a mineral. For instance, micas have a single cleavage, and break up into flat plates. Pyroxines have two cleavages at 90 degrees to each other, and break into square prisms. Calcite has three at 120 degrees, and naturally breaks into rhombs. Different minerals may have the same cleavage, but it helps to narrow down a mineral's identity.
Proportions work because they show the relationship between different quantities by comparing them using fractions or ratios. They are useful for scaling up or down values while maintaining their relative sizes. This makes proportions a powerful tool for solving a wide range of problems in mathematics and real-life situations.
It's the silica crystals that make horsetail fern (Equisetum hyemale) a scratchy tool.Specifically, the plant forms silica crystals on the cell walls of its stems and branches. The crystals form in response to the drying of the plant's parts. It is the persistence of these crystals in the branches and stems that make the plant a scouring tool, in many places and throughout many time periods.
To test cleavage in a mineral, you can use a sharp tool, like a knife or a fingernail, to apply pressure on the mineral's surface along its natural planes of weakness. When the mineral splits, observe whether it breaks smoothly along these planes, indicating cleavage. The quality of the cleavage can be assessed by examining the flatness and angularity of the resulting surfaces, as well as how easily the mineral splits. Different minerals exhibit different cleavage patterns, which can help in their identification.
No, a plumb bob is a weighted tool used by carpenters and builders to establish a vertical reference line or ensure something is perfectly vertical. A chalk line is a tool used to create straight lines on surfaces. They serve different purposes in construction and are not the same tool.

Comparing and contrasting are ways of looking at things to determine how they are alike and how they are different. Comparing involves identifying similarities and/or differences (e.g., apples and oranges are both fruit) whereas contrasting involves comparing two or more objects or events in order to show their differences (e.g., an apple has a thin skin that we can eat; an orange has a thick skin that we cannot eat).
This measurement is made with a measuring microscope.

When determining which minerals will scratch other minerals, you would need to refer to the Mohs Hardness Scale. The scale ranges from 1 (softest) to 10 (hardest) and is a tool used to measure the relative hardness of different minerals based on their ability to scratch each other.
A Venn diagram. It is a thinking tool used for comparing things.

The most effective tool for gas mileage comparisons is at gasmycar dot com. That site has the best tool for doing this type of research and information desired.
Electronegativity values are a useful tool to predict what kind of bonds will form.
A tool commonly used to measure minerals is a refractometer. This instrument determines the refractive index of a mineral sample, which can help identify the type of mineral based on how light is bent as it passes through the sample.
