What you need
Instructions
- 1
Step 1
Gather all your materials and sit at a clear table.
- 2
Step 2
Place the paper horizontally on the table.
- 3
Step 3
Use your pencil to draw a medium circle near the left side of the paper for the cell body.
- 4
Step 4
Draw a long straight or slightly curvy line from the circle toward the right to make the axon.
- 5
Step 5
Around the axon draw a row of rounded sausage-shaped segments with small gaps between them to show the myelin sheath and nodes.
- 6
Step 6
Draw a big arrow above the axon pointing from the cell body toward the axon tip to show the signal direction.
- 7
Step 7
Color the cell body with one color using your colouring materials.
- 8
Step 8
Color the myelin sheath segments with a different color using your colouring materials.
- 9
Step 9
Color the exposed axon parts between the myelin segments with another color so they stand out.
- 10
Step 10
Use the black marker to draw a straight line from the marker to the circle and write "Cell Body."
- 11
Step 11
Use the black marker to draw a straight line from the marker to the segments and write "Myelin Sheath."
- 12
Step 12
Use the black marker to draw a straight line to one gap and write "Node of Ranvier."
- 13
Step 13
Use the black marker to write "Signal Direction" next to the arrow you drew.
- 14
Step 14
Take a photo of your finished axon drawing and share it on DIY.org.
Fun facts
How do you make an axon drawing where the child draws and colors an axon on paper?
Start by drawing a round cell body (soma) and a long thin line for the axon. Add bulb-like dendrites near the cell body and a terminal at the axon’s end. Draw segmented ovals around the axon to show myelin sheaths and leave small gaps for nodes of Ranvier. Use arrows along the axon to indicate signal direction. Finally, label each part clearly and color-code components to reinforce learning and make it visually engaging.
What materials do I need to make an axon drawing activity?
You’ll need plain paper or cardstock, a pencil and eraser for sketching, colored pencils or markers for filling in parts, and a fine-tip pen for labels. A ruler helps draw a straight axon, and sticky notes or index cards can serve as removable labels. Optional items: printed reference images of neurons, stickers for terminals, and a laminated sheet if you want reusable practice with dry-erase markers.
What ages is the axon drawing activity suitable for?
This activity suits kids roughly ages 6–14. For ages 6–8, simplify shapes and focus on coloring and basic labels like 'cell body' and 'axon.' Ages 9–11 can add myelin, nodes, and arrows showing signal flow. Teenagers (12–14) can include finer details, compare myelinated versus unmyelinated axons, and write short explanations. Always supervise younger children and adapt complexity to each child’s interest and attention span.
What are the benefits of making an axon drawing with kids?
Drawing an axon boosts visual learning and helps children remember nerve structure by combining labeling, coloring, and arrows to show signal flow. It strengthens fine motor skills, reinforces science vocabulary (soma, myelin, nodes), and encourages curiosity about biology. The activity also promotes observation, sequencing (how signals travel), and can spark discussions about nervous system function, health, and careers in science, all in a hands-on, low-cost format.

What can we use if we don't have a black marker or some colouring materials?
If you don't have a black marker use a dark pen or sharpened pencil to draw the straight label lines and write names, and substitute crayons, markers, or watercolors with colored pencils or gel pens for the coloring steps.
My myelin sheath segments look uneven or the gaps are wrong—how can I fix that?
Before drawing the rounded sausage-shaped myelin segments, lightly mark equal tick marks along the long axon line with your pencil so the myelin sheath segments and small gaps (nodes) line up neatly as shown.
How can I change the activity for different ages?
For younger children pre-draw the medium circle cell body and a straight axon for them to color the cell body, myelin sheath segments, and nodes, while older kids can draw a curvy axon, add more labels, and measure or count nodes using a ruler and colored pencils.
How can we extend or personalize the finished axon drawing before sharing it on DIY.org?
Personalize your finished axon by adding a background or nearby neurons, labeling extra parts with the black marker, or creating a short stop-motion sequence of a colored dot moving along the axon to show signal direction and then photograph it for DIY.org.
