on its potential to support a broad range of science-specific learning outcomes and intersect with related institutional players and broader societal interests. Here we introduce, and in Chapter 3 we expand upon, six interweaving strands that describe goals and practices of science learning (see Box 2-2). It is important to note that while these strands reflect conceptualizations developed in research, as a set they have not been systematically applied and analyzed. The strands are interdependent—advances in one are closely associated with advances in the others. Taken together they represent the ideal that all institutions that create and provide informal environments for people to learn science can strive for in their programs and facilities.

Strand 1 addresses motivation to learn science, emotional engagement with it, curiosity, and willingness to persevere over time despite encountering challenging scientific ideas and procedures over time. Research suggests that personal interest and enthusiasm are important for supporting children’s
