Science 90

Course Information / Credit Recovery Units

The four goals of the K-12 Science curriculum are:

  • Understand the Nature of Science and STSE Interrelationships – Students will develop an understanding of the nature of science and technology, their interrelationships, and their social and environmental contexts, including interrelationships between the natural and constructed world.
  • Construct Scientific Knowledge – Students will construct an understanding of concepts, principles, laws, and theories in life science, in physical science, in earth and space science, and in Indigenous Knowledge of nature; and then apply these understandings to interpret, integrate, and extend their knowledge.
  • Develop Scientific and Technological Skills – Students will develop the skills required for scientific and technological inquiry, problem solving, and communicating; for working collaboratively; and for making informed decisions.
  • Develop Attitudes that Support Scientific Habits of Mind – Students will develop attitudes that support the responsible acquisition and application of scientific, technological, and Indigenous knowledge to the mutual benefit of self, society, and the environment.
