Curated OER
The Wheels on the Bot Go Round and Round, Part I
Students determine how speed is measured. In this physics instructional activity, students design an experiment to find out if the robot's drive wheel size affects its speed. They collect data and discuss results.

Quadratic Relation and Parabola
Students identify the vertex and intercepts of a parabola. In this algebra lesson, students graph parabolas and factor quadratic equations. They perform transformation on the parabolas.
Curated OER
"Go-Car" Lab
Students construct a car based on directions given. In this physics lesson, students calculate average speed using distance and time information. They collect data and create a graph of distance vs. time.

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...
Curated OER
Lift Relationships
Students use FoilSim (downloadable) to determine how lift is affected by varying parameters on the Airfoil simulation.
Curated OER
Actual Airflow vs. Ideal Airflow: Stalls
Learners use 3-D modeling techniques to observe the characteristic signature of the stall condition apparent on an airfoil at high angles of attack. They use FoilSim to compare the above with ideal airflow.

Friction Force
Students investigate friction force on a variety of objects such as bricks and cardboard boxes. They use a force probe to collect data on the changes in force required to drag the objects across a variety of surface types.
Curated OER
Ice Cold
Students design and conduct an experiment to investigate what happens when salt and ice come together and to determine if one form of salt is better for melting ice on steps and sidewalks.
Curated OER
Rate of Solvation
High schoolers test factors that may affect the rate at which sugar dissolve in water. They conduct two studies: One is to test the effect of temperature on the rate of solvation and the other is to test a factor which Students come up...
