This guide offers Spanish-speaking parents ways in which they can help their children learn about science at home and in the community. Science is a way of looking at the world. It uses everyday techniques such as observation and classification to give us information about things and how they work. Advice to parents that want to support their children's scientific learning includes letting children take the initiative, making time for science activities, encouraging children to talk about their observations and thoughts, showing children how they can find the answers to their questions, displaying enthusiasm for learning, being prepared for the teachable moment, and taking safety precautions. Themes and activities are suggested that demonstrate physical or chemical change, organization, measurement, classification, cause and effect, and structure and function. An outline provides information on children's exploratory behaviors and thinking skills at ages 3-5, 6-8, and 9-12. Lists of simple activities provide opportunities to learn about animals, the weather, energy and conservation, earth and space, plants, and physical and chemical properties.
