Circuits
Compare series and parallel networks with a real circuit schematic.
Open circuits investigationEngineering investigations
Predict, change one variable, test the model, and record evidence in your lesson report. These simulations are learning models, not equipment authorizations.
Gears and drive ratios
Investigate output speed, ideal torque, and the effect of an idler.
Open gears and drive ratios investigationMeasurement and tolerances
Explore resolution, rounding uncertainty, and borderline inspection decisions.
Open measurement and tolerances investigationFeedback and sensor faults
Compare open-loop and closed-loop behavior using a numerical rover trace.
