Lift Relationships
Young scholars use FoilSim (downloadable) to determine how lift is affected by varying parameters on the Airfoil simulation.
Curated OER
Building a Pill Bug Palace
Students make "pets" of isopods (potato bugs) to determine their preferred environment and food sources. They record their results on a bar graph and in a scientific report.
Curated OER
Keep the Environment Clean
Students discuss ways our environment becomes polluted. They make a list of ways to keep it clean.
Curated OER
Upside-Down Wings
Young scholars use FoilSim to demonstrate that the graphic analysis of the airflow around one object can be used to hypothesize airflow graphs for objects as they are elongated from a sphere to an airfoil shape.
Curated OER
Design of Airfoil for Given Lift
Students use FoilSim to design an airplane wing that generates a given lift. As they change parameters such as airspeed, altitude, angle of attack, thickness and curvature of the airfoil, and size of the wing area, the software...
