BSCS Science: An Inquiry Approach is a three-year program in the sciences for high school. This program introduces students to the core concepts in inquiry, the physical sciences, the life sciences, and the earth-space sciences. In addition, this curriculum engages students across the disciplines in relevant contexts that explore the standards related to science in a personal and social perspective and science and technology. This program provides high school students nationwide with a rigorous, coherent alternative to the traditional sequence of biology, chemistry, and physics. Supported during its development by the National Science Foundation, one link is to the publisher's website and another is to relevant research and evaluation.
