xeed learn is a free site for classrooms. Follow a plant through a Philadelphia year. Built
Your notes stay on this device until you turn them in. Class sign-in with a code is Proposed.
Labels: Decided, Built, Proposed, Open
Students observe a real plant, test ideas in a simulation and hand in work. Built
Mark four leaves on a real plant.
Say what you expect, then replay a recorded year in the simulation.
Write your new idea beside your first look.
Come back, check your idea against what changed, then hand it in.
Today it centres on one module: a simulation of how a plant answers a year of weather. Built
Anyone can use it, in class or on their own. Built
Observe a real plant, test an idea in the simulation, then visit the plant again: that is the learning loop. Built
Pick a real plant near school, mark four leaves and save your first look.
You’ll leave with: A saved visit and a link to turn in.
Your own notesYour own observations are the record.
Choose a real plantReplay 2025 weather. Turn it up by 1, 2 or 3 °C and compare.
You’ll leave with: A prediction you can check against your own plant.
Weather: NOAA 2025Plant: teaching modelA model, not a forecast for your tree.
Replay 2025Look at the same plant again, compare, and save your new idea.
You’ll leave with: A new idea (B) beside your first look.
Your own notesYour first look stays as you wrote it.
Go back to your plantFind what you saved. Download a backup or turn it in.
You’ll leave with: Knowing where your work is.

Open your notesStudents pick a real plant and save a first look (A) and a new idea (B).
They send you a link with your class code; you open it on the Turn-in page.
Students get a card that gathers their plant’s record. Teachers see the same work, ready to grade. Proposed
Example card. Not a real student’s record.
Student card
Red maple, Acer rubrum
Garden groupSchool garden
Plant, species, visits, predictions, simulation results and new ideas, on one card.
Field, prediction and simulation records would arrive in one place, with a rubric, on their own screen.
AI helps students ask better questions in the field. It never grades: the teacher does. Proposed
Today a student sends a link, and the teacher opens it read-only. Built
For teachers
A verified teacher creates a class and gives each student a code. Students don’t register. Proposed
The teacher’s school identity is checked once.
Set up a class: its plants, dates and tasks. Each student gets a profile and a code.
Students type their code. There is nothing else to remember.
How teachers are verified is still open; a school email domain may work. Open
Some schools limit devices, so in class a code is each student’s link to their work.
Depends on a privacy decision.
Student code
ABCD-1234
Nothing on this page needs an account today.
Teachers sign in once their school identity is checked. Proposed
Students sign in with the code their teacher gives them. Proposed
In time everyone gets an account. Until then, students in class use their code. Proposed
xeed learn is the education branch of the Xeed project, made in Philadelphia.
The goal, later, is a wider natural-science platform. Decided
Every dataset and study: Sources
Start with either one. Bring a question across, then come back to check it.
Keep what you saw and explain what you think might happen.
Replay the weather, change one thing and compare the model’s response.
Look at the same plant again. Compare your evidence with your prediction.
Field records and model output are different evidence. Opening the other activity keeps this tab in place; it does not move your records.
