Center: Explained

In science, the term "center" refers to the middle point of an object or a system. The center is often used to describe the point around which other parts of the object or system are arranged or move.

For example, in the context of the solar system, the sun is considered the center around which the planets revolve. Similarly, in the context of a cell, the nucleus can be considered the center of the cell, as it contains the genetic material and controls the cell's activities.

The resources above cover the following skills:

LIFE SCIENCE

Ecosystems: Interactions, Energy, and Dynamics

Obtain information from literature and other media to illustrate that there are many different kinds of living things and that they exist in different places on land and in water (e.g., woodland, tundra, desert, rainforest, ocean, river).

EARTH AND SPACE SCIENCE

Earth’s Systems

Make observations from media to obtain information about Earth’s events that happen over a short period of time (e.g., tornados, volcanic explosions, earthquakes) or over a time period longer than one can observe (e.g., erosion of rocks, melting of glaciers).

Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).
