About ScienceTheGuide
A guide built the way science is: one checked step at a time.
ScienceTheGuide is a free, growing guide to biology and chemistry. We explain ideas plainly, put working tools beside them, and show the data so you can see it for yourself.
01 · WHY WE EXIST
Science should not need a decoder.
Good explanations of biology and chemistry exist, but they are scattered: a textbook chapter here, a calculator on another site, a chart with no source somewhere else. ScienceTheGuide brings the three together on one page.
Each topic gets a guide you can read in one sitting, the reference values it depends on, a tool to try it, and a chart that shows the numbers. Pages link across fields, because a cell is chemistry and a reaction can be biology.

02 · WHAT WE HOLD TO
Four rules for every page.
Clear before complete
Start with the idea in plain words. Detail and exceptions come after, never instead.
Sourced and dated
Every value names where it came from and when the page was last checked.
Learn by doing
Where a topic has a calculation, the tool sits next to the explanation.
Grows in the open
New pages are added steadily, and corrections are shown, not hidden.
03 · OUR METHOD
How a page gets made.
We borrow the shape of the scientific method: ask, gather, test, publish, and stay ready to be corrected.
STEP 01
Question
We pick a topic people actually search for or get stuck on.
STEP 02
Sources
Textbooks, standards bodies and primary data are gathered and noted.
STEP 03
Draft
The guide is written, with its tool and chart built alongside.
STEP 04
Review
A second person checks the facts, the numbers and the tool results.
STEP 05
Revise
Published pages are re-checked and updated when readers flag a problem.
04 · WHO IT IS FOR
Anyone who needs the answer and the reason.
- Students Revise a topic and check your working.
- Teachers Charts and tools ready to put in front of a class.
- Lab workers Quick calculators and reference values at the bench.
- Curious readers Understand the science behind everyday things.
05 · THE PEOPLE
Who writes and checks it.
Questions about ScienceTheGuide
- Content is written by science educators and subject specialists, then checked against primary sources including NCBI Bookshelf, IUPAC and NIST. We follow the same evidence-based editorial approach as peer-reviewed educational platforms.
- If you spot an error, email us. We aim to review corrections within 48 hours and publish a correction note on the affected page. Our approach mirrors the correction standards of Nature Portfolio — we correct, do not delete, and note the change.
- No. ScienceTheGuide is an independent educational resource. Always verify content against your own syllabus from your exam board (AQA, OCR, Edexcel, College Board) and your course textbook.
- Yes, for non-commercial educational use. Always cite the original primary source listed on each page rather than ScienceTheGuide itself — for example, cite IUPAC for atomic weights, not ScienceTheGuide. For broader open licensing, see the Creative Commons Attribution 4.0 licence.
