One account, the whole practical
Plot45 is the practical-work suite for school science. Signing in for the first time creates your account — it's free, and there's nothing to install.
- Plot — the data-plotting app. Type in your readings and get an honest graph: error bars, best-fit lines and real uncertainty. Free for everyone, even without an account.
- Sketch — draw your experiment setup with neat lab-equipment symbols, ready to paste into your report.
- Write — write the lab report itself on real A4 pages, with your graphs and sketches dropped in as numbered figures.
A free account includes Sketch, Write and a cloud workspace with 5 saved files. Teachers can run a whole class on the Teacher plan.
