Step-by-Step Instructions

Step 1: Sketching the Brain Stem

Pencil sketch of the lower brain stem using three connected curved lines.

Start by drawing three connected curved lines at the bottom of your page. One line should be slightly longer than the others. Teacher's Tip: Think of this as the base where the brain meets the spinal cord; keep the curves soft and fluid.

Step 2: Outlining the Cerebellum

Adding two overlapping U-shaped lines to the base to form the cerebellum.

Draw two large, overlapping 'U' shaped lines at the top of your stem. Teacher's Tip: These shapes don't need to be perfect circles; brains have irregular, bumpy textures, so let your hand be a little loose.

Step 3: Adding the Occipital Lobe

Drawing additional overlapping curved lines at the back of the brain structure.

Add more overlapping 'U' shapes toward the back of your drawing. Teacher's Tip: Vary the size of your 'U's to make the brain look more realistic and less like a uniform pattern.

Step 4: Defining the Parietal Lobe

Building the top section of the brain with more overlapping curved lines.

Continue adding overlapping 'U' shapes along the top of the brain. Teacher's Tip: If you make a mistake, don't worry! Just erase it and try again—that's exactly why we draw lightly at first.

Step 5: Filling the Center

Adding detail lines in the center of the brain structure.

Add a few more 'U' shapes in the center and across the bottom. Teacher's Tip: Try to connect these lines to the ones you've already drawn to create a continuous, folded look.

Step 6: Shaping the Temporal Lobe

Adding curves to the front section to define the temporal lobe area.

Add more overlapping curves near the front to form the temporal lobe. Teacher's Tip: Keep your pencil moving in a rhythmic motion to get those nice, smooth curves.

Step 7: Refining the Front

Adding final overlapping details to the front of the brain.

Draw additional overlapping lines at the very front of the brain. Teacher's Tip: Overlapping lines are the secret to making your drawing look 3D rather than flat.

Step 8: Finishing the Frontal Lobe

Completing the frontal lobe with final curved lines.

Complete the frontal lobe by adding a few more curved lines. Teacher's Tip: Look at your drawing as a whole—if there's a big empty space, add one more small 'U' shape to fill it in.

Step 9: Adding Texture

Adding final texture lines to the cerebellum area.

Add texture to the cerebellum at the back with several long, curved lines. Teacher's Tip: These lines should follow the contour of the brain to give it a realistic, folded appearance.

Step 10: Adding Color

A finished, colored cartoon brain drawing in shades of pink and grey.

Time to color! Brains are often depicted as a soft, pinkish-grey. Teacher's Tip: Use light pressure with your pink crayon and blend it with a touch of grey to get that perfect 'grey matter' look.
