Science Knowledge & Skills

Science Knowledge & Skills refers to the emerging ability to gather information about the natural and physical world and organize that information into knowledge and theories. Science learning during the early childhood years encourages children to discover the world around them and refine their understanding of it.

Toolkit for Professional Development

Use the toolkit's Know, See, Do, and Improve sections to learn about and try best practices in science teaching at the early childhood level. Find tools to review and improve science teaching practices.

The materials in this toolkit are designed as professional development activities and resources. Head Start programs use a research-based curriculum, and some programs add a supplemental curriculum with a focus on math and science. This kit can add to, but not replace, a quality curriculum that offers clear content, well-designed learning activities, and a research-supported scope and sequence.
