Plot45 · Est. 2026 · the practical-work suite
A complete suite for practical work
Sketch the setup. Take the readings. Fit them honestly. Write the report. Mark the class. Plot45 carries a school science practical from experiment design to marked feedback — in the browser, nothing to install.
Plot, Sketch and Write live inside — plotting is free, no account needed.
01 Design · Sketch Free
Draw the setup the way the mark scheme wants it
Draw your experiment setup with neat black-and-white symbols — beakers, meters, burners and cells that look like they came from a textbook.
- A palette of real lab equipment, plus arrows and labels for the details
- Exports as a crisp SVG or PNG on plain white paper
- Drops into your Write report as a numbered figure
02–03 Collect & analyse · Plot Free
From readings to an honest fit
The data-plotting app at the heart of Plot45: a table built for real measurements and a graph that treats uncertainty as physics, not decoration.
- Type in repeated trials and the mean and uncertainty work themselves out
- Fit straight lines and curves, with an R² that tells you the truth
- Max–min gradient uncertainty — m ± Δm, the way exam boards want it
- Export your graph as SVG, PNG or print — clean enough for an exam paper
04 Report · Write Free
Reports that come out looking like you meant it
Write your report on real A4 pages that print exactly as you see them — with your actual graphs, tables and sketches dropped in as numbered figures.
- Pages that behave like Word — page numbers, page breaks and all
- Equations that come out as proper mathematics, nothing to install
- Teacher comments land in the margin, right beside your words
05 Mark · Assignments
Set the practical. Watch it land. Mark it once.
One assignment equips every student with their own lab, sketch and report — and the class board fills in as the work comes home.
- Hand-ins lock the work, so you mark exactly what was submitted
- ManageBac-style rubrics or simple points — totals compute themselves
- Margin comments on the report, a score in the gradebook row
For schools & departments
Run your class on it
One Teacher plan covers you and your class. Students sign in with a handle and a password you hand out — no student emails, no personal data, and you can see every student's work read-only, any time.
- A cloud workspace for your labs, sketches and reports
- 10 student logins included — add more at $6 each, per year
- Assignments with hand-in, rubrics and margin comments
- Sketch and Write for the whole class
Plotting stays free
Plotting, uncertainty and export are free for every student, signed in or not — correctness is never behind a paywall. A free account adds Sketch, Write and 5 cloud files; the Teacher plan adds the classroom around it.
