Scientific Lab Notebook and Experiment Protocol Sheet for Word
A lab notebook entry has to let someone else repeat the experiment and trust the result: what you set out to do, the exact reagents and lots, the steps, what you saw as it happened, the raw data, and a witness signature. This template is a finished three-page entry for a Bradford protein assay in a teaching lab, with a safety checklist, a reagents table with lot numbers, a timed observation log and a standard-curve table that averages the triplicates with Word formulas.

What's inside
The document has 3 pages. Each part below is a heading in the file, so you can jump to it from the Navigation Pane (View > Navigation Pane).
| Part | What it covers | What you write |
|---|---|---|
| Experiment block | Which protocol, by whom, when | ID, version, researcher, date, notebook page, status |
| 1–2. Objective and safety | Why, and how to do it safely | Objective, PPE checkboxes, hazard callout |
| 3–5. Reagents, apparatus, procedure | What you need and what you do | Reagents with lots and expiry, equipment, numbered steps |
| 6–7. Log and data | What happened and what you measured | Timed observations; triplicate readings with formula means; results |
| 8. Sign-off | Who vouches for the record | Statement, researcher and witness signatures |
Before you start
- Read the safety data sheet for every reagent and note the hazards in the callout.
- Check that reagents are in date and write down lot numbers before you start; they matter if results look wrong later.
- Decide replicates and controls in advance and build the data table to match.
Step-by-step guide
Fill in the experiment block
Type the protocol ID, version, researcher and notebook page, and pick the date and status.
Complete the safety section
Tick each PPE and safety item before starting, and update the hazard callout for your reagents.
List reagents and apparatus
One row per reagent with concentration, amount, lot and expiry; then the equipment and settings.
Follow and edit the procedure
Keep steps numbered and specific (volumes, times, temperatures). Note any change in the observation log.
Log and record data
Write observations with times as they happen. Type readings over the sample numbers, then select the data table and press F9 to update the means.
Report and sign
Fill in the results, describe the analysis in a sentence, and sign with a witness.

Every field, control and style, explained
The code in each card is read straight from the .docx file (the XML Word stores, or the field code you see with Alt+F9), so it is exactly what the template contains.
<w:lvl w:ilvl="0">
<w:start w:val="1"/>
<w:numFmt w:val="decimal"/>
<w:pStyle w:val="Heading1"/>
<w:lvlText w:val="%1."/>
<w:lvlJc w:val="left"/>
<w:pPr>
<w:ind w:left="440" w:hanging="440"/>
</w:pPr>
</w:lvl>
<w:lvl w:ilvl="1">
<w:start w:val="1"/>
<w:numFmt w:val="decimal"/>
<w:pStyle w:val="Heading2"/>
<w:lvlText w:val="%1.%2"/>
<w:lvlJc w:val="left"/>
<w:pPr>
<w:ind w:left="660" w:hanging="660"/>
</w:pPr>
</w:lvl>The section numbers (1., 2., 6.1 …) are not typed. A multilevel list is linked to the Heading 1 and Heading 2 styles, so any paragraph you set to Heading 1 gets the next number and the table of contents picks it up.
Piece by piece
<w:pStyle w:val="Heading1"/>- Links list level 1 to the Heading 1 style (level 2 to Heading 2).
<w:lvlText w:val="%1."/>- Level 1 shows its counter and a period: 1., 2., 3.
<w:lvlText w:val="%1.%2"/>- Level 2 shows the parent number, a period and its own counter: 6.1, 6.2.
<w:ind w:left="440" w:hanging="440"/>- Hanging indent so wrapped heading text lines up after the number.
In the sample: 1. Objective, 2. Safety, 3. Reagents … (9 headings)
How it is used: To add a section, type the heading, then pick Heading 1 (Ctrl+Alt+1) or Heading 2 (Ctrl+Alt+2) on the Home tab. Numbers after it update by themselves.
How to change it: Home > Multilevel List > Define New Multilevel List to change the format (for example "Section 1"). Keep "Link level to style" set to Heading 1 and Heading 2.

Both recalculate when the document is printed, saved as PDF or scrolled in Print Layout.
Piece by piece
PAGE- The number of the page the field sits on.
NUMPAGES- The total number of pages in the document.
In the sample: Page 1 of 3 on the first page
How it is used: Nothing to do: add or delete pages and the numbers follow.
How to change it: Double-click the footer to edit the text around the fields. Insert > Page Number > Format Page Numbers sets the starting number.
Learn this: How to Set Up Pages in Word: Margins, Breaks, Headers, Footers, and Page Numbers →{ SEQ Table \* ARABIC }Each table caption uses a SEQ field that counts tables in order. Insert a new captioned table in the middle and every later caption renumbers.
Piece by piece
SEQ Table- A counter named "Table". Every SEQ Table field adds 1.
\* ARABIC- Show the counter as 1, 2, 3.
In the sample: 1 caption(s): Table 1
How it is used: Captions are what a "see Table 2" cross-reference points to (References > Cross-reference).
How to change it: References > Insert Caption adds a new one. If numbers look stale, press Ctrl+A then F9 to update all fields.

{ =AVERAGE(B3:D3) \# "0.000" }
{ =AVERAGE(B4:D4) \# "0.000" }
{ =AVERAGE(B5:D5) \# "0.000" }
{ =AVERAGE(B6:D6) \# "0.000" }
{ =AVERAGE(B7:D7) \# "0.000" }Some cells are Word formula fields, not typed numbers. Word tables address cells like a spreadsheet: columns A, B, C from the left and rows 1, 2, 3 from the top. A field such as { =B2*C2 } multiplies two cells, and { =SUM(ABOVE) } adds every number above it in the column.
Piece by piece
=B2*C2- Multiply the cells in column B and column C of row 2.
=SUM(ABOVE)- Add the numbers above, up to the first empty or text cell.
\# "#,##0.00"- Number format: thousands separator and two decimals.
In the sample: 6 formula fields. Last result: 0.703
How it is used: Type the new counts, then select the whole table and press F9 to recalculate. Word does not recalculate table formulas on its own the way Excel does. To refresh them on every print, turn on File > Options > Display > Update fields before printing.
How to change it: Right-click a result > Edit Field > Formula to change the formula or number format. Press Alt+F9 to show every field code at once.

Learn this: How to Use Styles and the Navigation Pane in Word →Tips and limits
- Never delete a mistake; strike it through, initial it and write the correction next to it.
- Record what actually happened, even when it differs from the protocol, and say why.
- Word formulas only update when you press F9; check the means before you sign.
- Keep cells used by formulas as plain numbers (no units or symbols), or the formula skips them.
- Use your lab’s electronic notebook if it has one; this template works as a printable or shareable protocol and record sheet.
