TerraWatch — a nature-watch world of wildlife and field science

🌿 TerraWatch

Be a citizen scientist: notice the world closely, classify what you find, and read the data — the same skills real scientists use to help their communities.

Classify a find Read the data
Level 1
Real Field Science Do the real thing: GLOBE cloud watching, a bird count and a daily rain gauge — the methods real scientists use. Practise, then record your own observations.

Start here

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.
Brain Break Take a quiet moment between field trips — a fun riddle or a short breather. Brain breaks help you remember what you learn.

All activities

Observe & investigate

Cloud Watch The NASA GLOBE Clouds protocol — estimate cloud cover the four-quarters way, then record your real sky. Bird Count The bird-count rule — the most of each kind at one time — then a real 15-minute watch. Rain Gauge Read a CoCoRaHS rain gauge to the hundredth of an inch, then keep a daily rain report. My Field Log Your real observations, on this device — CSV and print for the grown-up who sends them in. 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, days active, 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.
