Core Skills Analysis
Science
- Fasola explored the principles of aerodynamics by shaping cardboard wings and observing how wing curvature and surface area affect lift and glide distance.
- She investigated the four forces acting on a flyer—gravity, lift, thrust (from the rubber‑band launch), and drag—and noted how changes in weight (binder clip) altered flight stability.
- The activity introduced energy transformation, showing how stored elastic potential energy in the stretched rubber band converts to kinetic energy during launch.
- Fasola examined material properties, learning how tape strength, cardboard stiffness, and the friction of the binder clip influence the glider’s structural integrity and flight performance.
Tips
To deepen Fasola’s understanding, have her keep a flight log that records wing dimensions, rubber‑band tension, and flight distance, then graph the results to see trends. Next, challenge her to redesign one wing shape (e.g., a delta or rectangular wing) and test which yields the longest glide, encouraging hypothesis‑testing and iterative design. Incorporate a simple wind‑tunnel made from a box fan to explore how airflow speed changes lift, and let her calculate the estimated lift using the formula L = ½ ρ v² A Cₗ. Finally, connect the project to real‑world engineering by researching how birds and aircraft use similar principles, and have her present her findings in a short oral report or poster.
