N1  - Includes bibliographical references (pages 81-83); The melting snowman -- Why balloons float -- The world's best paper airplane -- How do animals survive in winter? -- Low-friction sledding -- Further exploration
N2  - A melting snowman leads her--of course!--to explore climate change and how to reduce her carbon footprint. The helium balloons at her eleventh birthday party beg questions--naturally!--of molecular structure, weights of gases,and neutral buoyancy. An afternoon making paper airplanes brings discoveries in aerodynamics. Tracks in the snow raise questions of how animals survive the winter. And an afternoon of sledding slides right into an investigation of momentum, acceleration, and friction
