具体描述
For ages 7-9. Young readers become scientists in the field when this activity book sends them off to answer the question Why do we have winter? with experiments and projects that mix real science with real fun. Combining hands-on learning with trivia, jokes, riddles, and terrific illustrations, chapters start with the "tools" of science -- the scientific method and how to keep a science journal -- and then investigate the winter constellations, long nights and long shadows, animal tracking in snow, and food-gathering behaviour in birds. Several activities centre on water and ice, including: The Freezing Point of Water' Making Ice Cream; and The Amazing Snowflake Crystal; while indoor projects include the study of static electricity and a recipe for simple yeast bread.
