Mineral, Rocks, Soil (Tuesday)

What is a Mineral?

To understand rocks, we must first understand minerals. A mineral is a naturally occurring, inorganic solid with a definite chemical composition and an ordered internal crystalline structure.

To be classified as a mineral, a substance must meet five specific criteria:

  1. Naturally Occurring: Formed by natural geologic processes (not man-made).

  2. Inorganic: Not alive, and never was part of a living organism.

  3. Solid: Maintains its shape and volume at standard temperatures and pressures.

What is a species, Variation in species (Monday)

1. What is a Species?

Defining a "species" sounds simple, but it is one of the most debated concepts in biology. The most widely accepted definition in modern biology is the Biological Species Concept.

The Biological Species Concept

A species is a group of organisms that can interbreed in nature to produce viable, fertile offspring, and are reproductively isolated from other such groups.

  • Viable: The offspring survive to adulthood.

  • Fertile: The offspring can successfully reproduce themselves (e.g., horses and donkeys can mate to produce a mule, but because mules are sterile, horses and donkeys are considered separate species).

Seeing forces (sunday)

1. What is a Force?

A force is a push or a pull acting upon an object resulting from the object's interaction with another object.

While you cannot physically "see" a force itself with your eyes, you can see what it does. Forces cause changes in an object's:

  • Speed: Speeding up (acceleration) or slowing down (deceleration).

  • Direction: Changing the path of a moving object.

  • Shape: Stretching, compressing, bending, or twisting.
