SCIENCE FUN WITH TOY BOATS AND PLANES

Easy experiments to do at home or school with home equipment, showing basic principles of how boats float and move and how planes fly.

Grade 2-5 An introductory-level book for exploring physics concepts through experiments with boats and planes. The relationships between weight and gravity, balance and the center of gravity, friction, equal and opposite reactions, air streams and lift, propulsion, drag, and air pressure are simply explained through their application to the toys. The clear text is brief and is supplemented by clarifying illustrations and step-by-step diagrams in gray and yellow. For each concept, simple experiments are outlined, along with questions that will pique interest and help to direct readers. The materials can be easily found at home or at school. Young experimenters can do many of the experiments alone, but some require adult supervision for cutting. The book could be used by individuals, small groups, or by teacher and class in science study. It is open-ended, inviting readers to continue or to expand the experiments.
