What Is Process Art?
Process art focuses on creativity, exploration, and experimentation rather than creating identical finished projects. Instead of following strict directions to make a craft look a certain way, kids are encouraged to explore materials, movement, color, and techniques.

This ocean wave activity is a great example of process art because every painting turns out differently. Kids can experiment with blowing watercolor paint across the page, revealing the hidden crayon drawings
The finished artwork feels creative, modern, and ocean-inspired, yet simple enough for younger children to enjoy.

Supplies Needed
- White cardstock or watercolor paper (heavyweight to absorb liquid)
- White crayon
- Liquid watercolors
- Straw
- Tape
- Shallow tray or baking pan
How to Make Ocean Wave Process Art
Step 1: Prepare the Paper
Tape the paper to a shallow tray or baking pan to help contain the watercolor paint.
Step 2: Draw Ocean Waves
Use a white crayon to draw wave lines, swirls, zigzags, bubble patterns, or curved ocean shapes across the paper. The crayon creates a wax resist effect that appears once watercolor paint is added.
Kids can also draw:
- fish
- seaweed
- coral
- jellyfish
- ocean spirals
for additional ocean details.

Step 3: Add Watercolor Paint
Add small drops of blue, turquoise, teal, or green liquid watercolor paint onto the paper. For younger kids, begin with smaller amounts of paint to make the process easier to control.

Step 4: Blow the Paint Across the Paper
Use a straw to gently blow the watercolor paint across the page. As the paint spreads, the hidden ocean wave designs begin to appear.
Encourage kids to experiment with:
- blowing in different directions
- mixing colors
- layering paint
- creating fast or slow “waves”

Step 5: Let the Artwork Dry
Allow the paintings to dry completely before displaying.

Teacher Tips
- Use cardstock or watercolor paper for sturdier finished artwork.
- Demonstrate how to blow gently through the straw instead of sucking.
- Place trays underneath the paper to help manage messes.
- Limit the amount of watercolor at first to avoid oversaturating the paper.
- Prepare taped papers ahead of time for easier classroom setup.
- Play ocean-themed music during the activity for a calming art center.
Easy Ocean Art Variations

Ocean Waves Process Art FAQ
What age is ocean wave process art best for?
This activity works well for preschoolers, kindergarteners, and elementary kids because it can easily be adapted for different ages.
Can I use regular watercolors instead of liquid watercolors?
Yes. Liquid watercolors create better flowing effects, but watercolor trays or watered-down washable paint also work well.
What is wax resist art?
Wax resist occurs when the wax on the crayon repels watercolor paint, revealing hidden designs beneath.
Is this activity messy?
Using shallow trays and smaller amounts of watercolor paint helps keep cleanup manageable for classrooms and home use.
Can I turn this into a collaborative art project?
Yes! This activity works especially well as a classroom mural or ocean-themed bulletin board display.
