The Ready To Learn (RTL) Activities Guide is a set of flexible, 60-90 minute-long activities designed to engage young children in hands-on science learning inspired and supported by PBS KIDS media. The activities use guided play with kids, ages three to eight, and appropriate digital and tangible tools meant to encourage the development of science inquiry and engineering design skills. Each activity also includes a resource list of additional videos, activities, games and books—all tied to the same topic.
