Projectile Lab Predict which launch lands farther before the arcs are drawn — learn why 45° flies farthest. 
Pendulum Lab Predict which pendulum swings slower — discover only LENGTH changes the timing. 
Circuit Lab Predict which bulb glows brighter — series vs parallel, then see the power per bulb. 
LabSmith Journey A path through every kit — clear each stop of real practice, then move on. All activities
Predict-then-reveal labs
Projectile Lab Two launches at different angles and speeds — predict which lands farther, then watch both arcs draw. Pendulum Lab Change length, weight, or swing size — predict which swings slower, then isolate the variable that matters. Circuit Lab Wire the same bulbs in series or parallel — predict which glows brighter, then see the power per bulb. Teach the Cast Teach a physics idea to a cast member still learning it — teaching makes it stick.
Practice & play
Mixed Practice A short round across the kits you have played — brought back to make it stick. LabSmith Sprint Race your OWN best on what you already know. Timer optional, no penalty for a miss. Trick Questions Brain-teasers with a twist — spot why the obvious answer is a trap. LabSmith Duel 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room. Progress Your levels, streak, and how each skill area is coming along — saved on this device. Progress report For grown-ups — a private on-device snapshot mapped to the skill areas. Export a CSV or print.

Meet the cast — the characters who teach this
-
Query Ask a good question — sharp + answerable; 'Where science starts.' -
See Observe — gather raw data first; 'Look first. Talk later.' -
Guess Hypothesize — frame a testable guess; 'What if…?' -
Model Model it — build a small stand-in you can poke; 'Learn the big thing from the little one.' -
Meter Measure precisely — a number and a unit; 'How much, exactly?' -
Check Experiment — design + run the test; 'One test at a time.' -
Again Replicate — repeat to be sure; 'One result is a maybe. Do it again.' -
Because Argue from evidence — back a claim with the reason; 'I think Y, because I saw X.' -
Explain Explain the mechanism — the how-and-why that connects cause to effect; 'Know THAT, then know WHY.' -
Reflect Learn — interpret results + revise; 'What did we learn? What surprised us?'
