Correlations to National Science Standards

Grades K–4
Physical Science – Content Standard B
Properties of Objects and Materials

• Objects have many observable properties, including size, weight, shape, color, temperature, and the ability to react with other substances.
• Materials can exist in different states — solid, liquid, and gas. Some common materials, such as water, can be changed from one state to another by heating or cooling.
  

Science and Technology – Content Standard E
Understanding About Science and Technology

• People have always had questions about their world. Science is one way of answering questions and explaining the natural world.
  

History and Nature of Science – Content Standard G
Science as a Human Endeavor

• Although men and women using scientific inquiry have learned much about objects, evens, and phenomena in nature, much more remains to be understood. Science will never be finished.
  

Grades 5–8
Science as Inquiry – Content Standard A
Abilities Necessary to Do Scientific Inquiry

• Scientific explanations emphasize evidence, have logically consistent arguments, and use scientific principles, models, and theories. The scientific community accepts and uses such explanations until displaced by better scientific ones. When such displacement occurs, science advances.
  

Earth and Space Science – Content Standard D
Structure of the Earth System

• The solid earth is layered with a lithosphere; hot, convecting mantle; and dense, metallic core.
  

History and Nature of Science – Content Standard G
Nature of Science
Science as a Human Endeavor

• Scientists fomulate and test their explanations of nature using observation, experiments, and theoretical and mathematical models. Although all scientific ideas are tentative and subject to change and improvement in principle, for most major ideas in science, there is much experimental and observational confirmation. Those ideas are not likely to change greatly in the future. Scientists do and have changed their ideas about nature when they encounter new experimental evidence that does not match their existing explanations.
