Observation Lab Read a field observation, then PREDICT which animal group it belongs to — work a dichotomous key: feathers? backbone? how many legs? 
Data Lab Look at real citizen-science data — monarch counts, water temperature, dissolved oxygen — then predict the trend before you check. 
TerraWatch Journey A path through every kit — clear each stop of real practice, then move on. 
Teach the Cast Teach a science idea to a cast member still learning it — teaching makes it stick. All activities
Observe & investigate
Observation Lab Predict which group a specimen belongs to, then check — learn to work a dichotomous key like a real field scientist. Data Lab Predict the trend or how two measurements relate in real citizen-science data — reading the evidence is the heart of science. 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. TerraWatch 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. TerraWatch 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.

More ways to play
Meet the cast — the characters who teach this
-
Spot Observation + noticing — the chickadee-tween perched on a branch who teaches slow-noticing as the first scientific skill ('look once, then look again, slower; the second look usually finds more') -
Note Structured recording — the beaver-tween in notebook-pocket vest who teaches fact-vs-inference discipline ('write what you saw; then write what you think it means; don't mix them') -
Pin Geolocation + spatial-data discipline — the hummingbird-tween with pin-tail-feather who teaches that location-stamps + time-stamps make observations useful to other scientists ('where matters; when matters; the same plant in two places is two stories') -
Census Biodiversity counting + sampling — the raccoon-tween with tally-pattern vest who treats unglamorous repeated counting as the actual magic of science ('one bird seen is a moment; ten birds seen over ten days is a pattern; counting is the magic') -
Trend Change-over-time + agency-positive climate framing — the tortoise-elder with tree-ring shell and folding-graph showing both worrying AND hopeful trends; carries the eco-anxiety-gate anchor ('today is one dot; many dots make a line; lines can bend; your dot helps the line')
