This term describes material that allows all light to pass through it.

This phenomenon occurs when the moon passes between the Earth and the Sun.
What is a solar eclipse?
This process, often seen in insects, involves dramatic transformation in form and function during the life cycle.

This process describes how organisms change over time through adaptations.
What is evolution?
This material refracts or bends light, breaking it into its spectral colors, as demonstrated when light passes through it.
What is a prism?
These celestial bodies are composed mainly of hot gas, primarily hydrogen and helium, held together by gravity.
