Launch Fair Test LabRun the Graph Clinic: diagnose and fix sick lab-report graphs, then read them: values, slopes, trends and outliers. 10-question runs.
Launch Graph DoctorDispatch trains at the rail yard: couple conversion-factor cars so units cancel, then deliver the amount with the right sig figs.
Launch Conversion RailroadRun the lab's measuring desk: read cylinders, burets, rulers, thermometers and balances to the right digit. 10-question runs.
Launch Read the GlasswareWork a motion-capture studio: drive the actor so the recorder draws the director's position–time or velocity–time graph. 10-question runs.
Launch Walk the GraphPredict collisions with momentum, draw momentum arrows, and design crumple zones that keep the crash dummy safe. 10-question runs.
Launch Crash Test CenterRun a garage that diagnoses forces: draw every force on crates, cars, elevators and skydivers, predict the motion, then watch it move.
Launch Free-Body GarageBuild a marble track, place photogates, and calculate speed, acceleration and energy from gate time stamps.
Launch Marble Track LabPush, pull, hang and drop objects with force sensors. Live free-body diagrams, friction, an elevator, a tug-of-war and a skydiver.
Launch Forces & Newton's Laws LabCollide gliders on an air track with photogates and a force sensor. Momentum is conserved; kinetic energy isn't. Impulse and safety.
Launch Momentum & Collisions LabPoint a motion detector at walkers, carts, a tossed ball and falling filters; read slopes, areas and fits on live linked p, v, a graphs.
Launch Motion Graphs LabBalance energy bar charts, choose system boundaries and run stunt replays where every joule changes form or crosses the boundary.
Launch Energy Bar BuilderSkate a half pipe, swing a pendulum, launch a spring and build coasters while energy bars track every joule.
Launch Energy Transfer LabHeat water and metal blocks with a joulemeter, mix hot and cold in a calorimeter, and test insulation panels on a hot-plate rig.
Launch Thermal Energy & Heat Transfer LabRun an electronics repair shop: wire circuits to spec on a live board, find faults with a multimeter, and calculate what the meters read.
Launch Circuit Repair ShopWire batteries, bulbs, resistors and meters on a circuit board. Watch charges flow, bulbs glow and a live schematic follow along.
Launch Circuits LabRun the night shift at a radio station: read waves on the scope, use v = fλ, and tune the dials until each station or note locks.
Launch Radio DJMake waves on a rope, a slinky and in air. Measure λ and f, see v = fλ, hear pitch and loudness, and find standing waves.
Launch Waves & Sound LabStretch orbits, sweep equal areas, race the planets, and launch probes, then take a test at your level.
Launch Kepler's LawsBuild nuclei, explore decay and half-life, split and fuse atoms, weigh binding energy, and test radiation safety.
