The first objective is to test the student's understanding of science as a whole and the scientific empirical process. Students must demonstrate that they understand how to collect data, make observations, and plan and implement experiments. The questions test their ability to use the tools of scientific experiments, such as microscopes, thermometers, and rulers, and to organize and analyze data using graphs, maps and charts. The overall objective is to test the student's abilities as a scientist.
The second objective demonstrates the student's knowledge of the life sciences. The student must show an understanding of the basic concepts of biology, genetics, evolution and ecology. The test evaluates the student's understanding of plants and animals and their relationship to the environment. The objective requires observations about the adaptive qualities of animals and the environment, observation and description of habitats, and interdependency of plants and animals.
The third objective regards the student's understanding of the physical sciences. Students must demonstrate basic knowledge about energy, matter and motion. Knowledge of different kinds of energy sources, how light is reflected and refracted, the physical properties of matter, observation and measurement of sound are among the skills tested. Generally, students should know the concept that change does not occur without an outside force and should be able to identify the different physical manifestations of change in physical matter.
The fourth objective deals with the earth and space sciences. Students should be able to identify the characteristics of the moon, sun and earth and how past events have changed and shaped them. Students should be able to identify the planets of our solar system and describe lunar and seasonal cycles. Students should be able to identify the earth's properties, including rocks, water and gases, as well as renewable energy resources.
