The following standards and benchmarks apply to the entire, six-module Voyages Through Time curriculum. In evolutionary change, the present arises from the materials and forms of the past, more or less gradually, and in ways that can be explained. Science Science distinguishes itself from other ways of knowing and from other bodies of knowledge through the use of empirical standards, logical arguments, and skepticism, as scientists strive for the best possible explanations about the natural world. The historical perspective of scientific explanations demonstrates how scientific knowledge changes by evolving over time, almost always building on earlier knowledge.
Science often advances with the introduction of new technologies.
Solving technological problems often results in new scientific knowledge. New technologies often extend the current levels of scientific understanding and introduce new areas of research. Inquiry Formulate and revise scientific explanations and models using logic and evidence. Use tables, charts, and graphs in making arguments and claims in oral and written presentations. Timeline Activities Use ratios and proportions, including constant rates, in appropriate problems.
