Curated OER
Upside-Down Wings
High schoolers 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
Using 3-D Models for Code Validation with FoilSim
Young scholars use FoilSim to complete the activity to create tables of data sets comparing the lift values for a 3-D model of a symmetrical wing section to the values predicted by the FoilSim software.
Curated OER
Lesson Plan 2--3000 B.C. to 2000 A.D.?
Students, in groups, study the different writing systems from 3000 B.C. to 2000 A.D.
Curated OER
Wind Gauges
Students use FoilSim interactive software to become familiar with the way in which the flow of air across or around an airfoil affects its ability to create lift.
Curated OER
Showing the Lift Equation
Learners read an explanation from a NASA Web-based textbook, then demonstrate an understanding of the text by using it, along with FoilSim, to complete an activity that manipulates the lift coefficient equation.
