Proposed wording for the Science Common Expectations
and their associated Benchmarks
Understanding science and technology allows students to make informed decisions and to understand how these decisions impact the world. In this increasingly complex and technologically dependent world, it is important that all citizens have a basic understanding of science and technology. It is the responsibility of each person to make informed decisions regarding such diverse issues as siting landfills, emerging diseases, and advanced computer network systems and to understand how these issues impact the current and future quality of life. These science expectations were designed to provide high school graduates with essential knowledge to apply science concepts in today's society and to continue their education about science topics beyond their formal schooling.
At the completion of high school, students are expected to:
