When designing programs for science learning, it is important to consider that children's experiences with science begin years before they encounter science in the classroom. Children's developing understanding of science begins in their everyday activities and conversations about the natural and technical world. Children develop "scientific literacy" as they begin to learn the language of science (e.g., concepts such as "gravity" or "metamorphosis"), the kind of causal explanations that are used in scientific theories (e.g., the day-night cycle results from the rotation of the earth), and the
Classroom tasks should develop a spirit of inquiry and a sense of delight in discovery that will become part of the individual's learning style.
