SCIENTIFIC METHOD / GRAPH SKETCHNOTES

A picture of
your thinking.

Use your classroom sheet. Open a numbered step, try a change, then add a note and color as you review.

Paper & filled-in references

The illustrated guides use practice data. The blank sheets leave room for your explanations and drawings. Print at fit-to-page; use the separate graph paper when you need precise grids or a 50-dot circle.

Bar graph

Compare categories.

Blank sketchnote · Filled-in reference

  1. Organize. List each category and its value in your table.
  2. Label. Put categories on the horizontal (X) axis and values on the vertical (Y) axis. Copy the units from your table and add a clear title.
  3. Scale. Start the bars at zero. Choose equal number steps that fit your largest value.
  4. Draw and check. Draw bars with equal widths and equal gaps. Check each height against your table.

Line graph

Show change over time.

Blank sketchnote · Filled-in reference

  1. Organize. Keep each time with its measurement. Put the rows in time order.
  2. Label. Put time on the horizontal (X) axis and the measurement on the vertical (Y) axis. Include units and a title.
  3. Scale and plot. Use equal number steps on each axis. Each axis can have a different scale. Plot every pair by moving across to the time, then up to its measurement.
  4. Join and check. Use a ruler to join neighboring points in time order. Check every point against the table. Only include (0, 0) if your data include it.

Scatter plot

Look for a relationship between two measurements.

  1. Keep the pairs. One row is one pair of measurements. Keep the two values from each row together.
  2. Label. For these problems, put the first measurement on the horizontal (X) axis and the second on the vertical (Y) axis. Include units and a title.
  3. Scale and plot. Use an even scale on each axis that fits the data. Go across to X, then up to Y. Draw one dot for each pair.
  4. Check the pattern. Do not connect the dots. Check every pair, then describe whether the points tend upward, downward, or show no clear pattern. A pattern alone does not prove a cause.

Pie graph

Show parts of one whole.

Blank sketchnote · Filled-in reference

  1. Find the whole. Add the category counts to find the total.
  2. Find each share. For each category: percent = count ÷ total × 100. All the percentages should add to 100%.
  3. Count spaces. On your 50-dot circle, there are 50 spaces between neighboring dots. Each space is 2%. Spaces = percent ÷ 2. For example, 20% uses 10 spaces.
  4. Draw and check. Draw a starting line from the center to a dot. Count that category’s spaces clockwise, then draw a line from the center to the new boundary. Start the next category at that boundary and continue around. Count gaps, not dots. Add a title, category labels and percentages; check for 100% and 50 spaces in total.

Blank graph grids (PDF) · 50-dot pie paper (PDF)

The pie sheet’s plain circle is for sketching. On the precise 50-dot paper, count the spaces: each is 2%. A 100-part circle uses 1% per part.
