Fields in Science

Astronomers study objects as large as galaxies. Chemists study objects that can be as small as an atom. Even though scientists in each field study very different things, why are both astronomy and chemistry considered science?

• both fields are based on the same experiments

• both fields use the same basic scientific methods

• both fields require the same basic knowledge

• both fields use the same technology

An astronomer discovered a new comet in orbit around the Sun. He wants to learn more about the size, shape, and period of the comet's orbit. What type of investigation should the astronomer perform?

• Analyze data about similar comets that also orbit the Sun.

• Observe the behavior of the comet as it moves in its orbit around the Sun.

• Set up a controlled experiment with dependent and independent variables.

• Conduct a survey of astronomers to gather their opinions about the comet.
