Open it so that the edges of the semicircles form a 90 degree angle. Glue the layers onto the circle of yellow poster board and wait for the glue to dry.Label the layers with their names and thickness and any interesting facts that you can fit onto the piece of paper.The convective zone is about 65 percent the size of the radiative zone, so it would be just over 1.5 inches wide. For example, if you make the core 1 inch deep, your radiative zone is a little more than double the size of the core, so it would be 2 inches wide. Use your calculator to determine the ratios of the layers. Choose a color of paper for the core, the radiative zone, the convective zone, the photosphere, and the chromosphere. Now cut out circles of different colors of construction paper to represent the layers of the sun.This is the place where you’ll add the circle to show the different layers of the sun. Use your paper lantern while it’s closed and flat to trace a circle on lightweight yellow poster board.5 different colors of construction paper.ProblemĬreate a three-dimensional model of the interior of the sun. These bumpy areas called granules are areas of the sun where hot material comes to the surface before fading quickly. Sometimes the surface of the sun looks bumpy like sugar crystals. It’s surrounded by a ring called the penumbra. The umbra is cooler than the rest of the sun and has a strong magnetic field. The dark middle part of a sunspot is called the umbra. Today, we know that sunspots are caused by magnetic activity that changes the patterns of motion in the sun. Galileo then determined that the spots were actually on the surface of the sun. At first, they weren’t sure what the spots were and thought that they might be moons crossing the sun. In 1609, the invention of the telescope helped early scientists such as Galileo and Christoph Scheiner observe these spots. Sunspots are dark, oddly shaped areas on the surface of the sun, and they appear and disappear. In addition to layers, the Sun also has irregular areas called sunspots. The heat moves giant solar winds around the open spaces on the Sun. It’s also the widest at around 3 million miles thick. The outer layer is called the corona, and it’s the hottest part. It’s very hot, but it’s only visible with special instruments that help us see infrared light. The chromosphere is outside the photosphere and is just over 6,000 miles thick. It contains energy that’s in the visible light spectrum. The photosphere is the layer that we actually see when we look into the sky, and surprisingly, it’s only about 300 miles thick. Outside the convective zone are three layers. The convective zone is 125,000 miles thick. On earth, currents like this help make the wind. This is because they move on rising and falling currents of gas in a process called convection.
Here, the photons of energy move faster than in the radiative zone. Next to the radiative zone is the convective zone. This area delivers the energy from the core into other parts of the sun. The radiative zone is about 190,000 miles thick.
