Sample text

Astronomers can determine a star’s temperature by the type of light it emits. Red stars are cooler than blue stars as you can see from Table 4. Science Fair Project Idea With a little practice, you will be able to estimate time quite accurately with your sky clock. If you live near the eastern or western end of a time zone, your clock will appear to be a little fast or slow. How can you adjust your time estimate? Since the sky clock is set for standard time, how can you adjust your estimate for daylight saving time?

Gravitational pulls among the particles caused a general drift toward the center of the “cloud,” producing a contraction of the matter and higher temperatures. Because of rotation, the cloud became a flattened disk. Near the center, where temperatures were higher due to greater pressure, a protosun formed. ) Rotation kept some of the matter far from the center—out where it was still very cold. Continued contraction of the central part of the disk raised temperatures to millions of degrees. At such a high temperature, hydrogen began fusing to form helium, like a giant hydrogen bomb.

Slowly move the coin farther from your eye. Does the coin block out more or less of the bulb as you move it away? Hold the coin far enough away so that it blocks the center part of the lightbulb but leaves a ring of light around the edge. This is what happens during what is called an annular eclipse. In an annular eclipse, a thin ring of light is still visible all around the edge of the Sun. You can also move the coin so that it blocks out the top, bottom, or one side of the lightbulb. This is what happens during a partial eclipse when the Sun and Moon are not quite in line with your location on Earth.
