Built for the IB. Designed for inquiry.
Every HeyPlant investigation maps to the IB's own assessment criteria — so teachers spend their time teaching, not adapting.
Authentic inquiry, not cookbook labs.
Students formulate real hypotheses about a living organism and grapple with real data — noise, drift, and all.
A genuine K–12 vertical thread.
One platform carries a school from PYP wonder to DP internal assessment.
15+ unique IA topics per class.
Every student can run a distinct, non-simulated investigation — a real answer to the academic-integrity and collusion problem in DP sciences.
Interdisciplinary by design.
One sensor array powers Biology, Chemistry, Physics, ESS, Design, Mathematics, and Computer Science — plus rich TOK discussion.
Every programme, mapped to its own criteria.
PYP · Ages 6–11
The Wondering Years"Does our classroom plant wake up with the sun?" — leaf temperature + light, Grades 1–3.
"Can the plant tell us when the soil is too dry?" — soil moisture + transpiration, Grade 5 Exhibition.
MYP · Ages 11–16
Inquiry Becomes SystematicBiology (Gr 8): "How does blue light affect stomatal opening?"
Chemistry (Gr 10): "Calibrate a nitrate electrode and track its depletion over a growth cycle."
Physics (Gr 9): "Model the plant stem as a resistor–capacitor network from impedance data."
DP · Ages 16–19
Original Research, Real StandardsBiology: "How does the propagation velocity of wound-induced electrical signals in Mimosa pudica depend on stem temperature?"
Chemistry: "Determining the selectivity coefficient of a nitrate ion-selective electrode in the presence of phosphate."
Physics: "Characterising the impedance spectrum of a tomato stem from 100 Hz to 100 kHz."
ESS: "Correlating diurnal sap-flow velocity with traffic-derived PM2.5 levels in an urban tree."
CP
Career-related ProgrammeFor CP pathways in agritech, horticulture, and environmental technology, HeyPlant anchors the career-related study with DP sciences in support — connecting classroom inquiry to real careers in food systems and sustainability.
One investigation per grade, from first wonder to final IA.
You're never doing this alone.
