ANSWERS
1. Chemistry: The study of atoms and molecules, their structures, and their interactions to form
various substances.
2. Physics: The study of forces, energy and motion.
3. Earth Science: This field focuses on Earth's structure and composition, as well as the processes
that change Earth, such as volcanic and seismic activity.

,6. Controlled Exper- An experiment in which only one variable is manipulated at a time..
iment:
7. Independent The variable that is manipulated in an experiment.
Variable:
8. Dependent Vari- The outcome factor; the variable that may change in response to manipulations
able: of the independent variable.
9. Control Variable: A variable that is kept constant during a controlled experiment.
10. Observational The systems are observed as they appear in nature and researchers do not
Study: attempt to change them.
