Creating a Visual Representation of the Sun's Atmosphere

Selma's science fair project revolves around creating a visual representation of the sun and its components. In addition to the depiction of the sun's interior, Selma added a model of the sun's atmosphere to her presentation. This model helps to showcase the different layers of the sun's atmosphere in a creative and educational way.

Sun's Atmosphere Components

When creating the visual representation, Selma included several key components of the sun's atmosphere. These components include the photosphere, chromosphere, and corona. Each layer plays a unique role in the sun's atmosphere and contributes to the overall structure and function of the sun.

The photosphere is the visible surface of the sun and is where most of the sunlight we see comes from. Selma showcased this layer by sprinkling a thin layer of white flour, representing the outer layer of the sun's atmosphere. The photosphere is crucial for emitting light and heat from the sun.

The chromosphere is a thin layer of the sun's atmosphere located just above the photosphere. To depict this layer, Selma used a transparent red cellophane wrapper. The chromosphere plays a role in the sun's energy production and contains various interesting phenomena like solar flares and prominences.

The corona is the outermost layer of the sun's atmosphere, extending far into space. Selma represented this layer by sprinkling a thin layer of white flour. The corona is most easily observed during a total solar eclipse and is significantly hotter than the sun's surface. It consists of highly ionized gases that form the solar wind.

By accurately illustrating these components of the sun's atmosphere, Selma's science fair presentation not only educates others about the sun but also highlights the intricate dynamics and layers present in our closest star.
