Experiment Designer Given a real question, pick the one thing to change and the one thing to measure — then spot the tests that aren’t fair and say what went wrong. 
Predict · Observe · Explain Read a mini-experiment, guess what will happen, see the real results in a chart, then choose the explanation the evidence actually supports. 
Density & Buoyancy Lab Predict float or sink, work out density (mass ÷ volume), then change the mass and watch the beaker settle. 
ScienceForge Journey A path through every kit — clear each stop of real practice, then move on. All activities
Investigate
Experiment Designer Pick the one variable to change and the one to measure, then catch tests that aren’t fair — the heart of a real experiment. Predict · Observe · Explain Guess the outcome, watch the chart, then choose the explanation the evidence supports. Density & Buoyancy Lab Why a big steel ship floats but a tiny bolt sinks — predict, compute density, then watch the beaker settle. Teach the Cast Teach a science 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. ScienceForge Sprint A calm speed round 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. ScienceForge 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.
