Eighth grade students continue their involvement in scientific experimentation. They plan and conduct research projects that include classroom experimentations and literature reviews. Their research focuses on variables, repeated trials, and validating conclusions using evidence and data. Students share their work in written reports and oral presentations. They develop an in-depth understanding of the nature and structure of matter and the characteristics of energy and explore how technology applies to physical science principles. Eighth graders study the periodic table; physical and chemical changes; nuclear reactions; temperature and heat; sound; light; electricity and magnetism; and work, force, and motion. Teachers can visit the free companion web site for additional instructional support materials and information.

Science from the Latin word scientia , meaning "knowledge"  is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Modern science is typically divided into three major branches that consist of the natural sciences e. There is disagreement,   however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Science is based on research , which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products , armaments , health care , and environmental protection. Science in a broad sense existed before the modern era and in many historical civilizations.

NSTA has several position statements. Please explore them on NSTA's website. The mission of the Minnesota Science Teachers Association is to stimulate, coordinate and improve science teaching and learning for all. Climate change is one of the great scientific challenges this generation of students and teachers will face. With this in mind, the Minnesota Science Teachers Association takes the following position regarding climate change and teaching about climate change:. The Earth's global climate is not static but changes over geologic time scales in response to natural causes, or forcings, such as volcanic activity or sun luminosity.
