In this blog post we have written on how to make states of matter working model science project – diy | howtofunda

Creating a states of matter working model can be a fun and interactive way to understand the different states of matter: solid, liquid, and gas.

A simple states of matter working model that helps visualize and understand the concept of solid, liquid, and gas states

Creating a working model to demonstrate the three states of matter (solid, liquid, and gas) using cardboard and color paper is a fantastic science project. Here’s a step-by-step guide to help you build this model:

Materials Needed:

  1. Cardboard: For the base and partitions.
  2. Color Paper: For decorating and labeling.
  3. Glue or Hot Glue Gun: For assembling the parts.
  4. Scissors and Craft Knife: For cutting the cardboard and paper.
  5. Markers, Paint, or Colored Pencils: For adding details.
  6. Transparent Plastic or Cellophane: For representing liquids and gases.
  7. Cotton Balls or Sponges: To represent solids and add texture.
  8. Small Containers: To hold liquids.
  9. String: To suspend parts representing gases.
  10. Tape: To secure the components.

1. Prepare the Base:

  • Cut a rectangular piece of cardboard for the base of your model.
  • Optionally, cover the base with color paper to make it more visually appealing.

2. Create the Partitions:

  • Cut two pieces of cardboard to form partitions, creating three equal sections on the base.
  • Glue the partitions vertically onto the base, dividing it into three sections.

3. Decorate the Partitions:

  • Cover each section with color paper to differentiate the states of matter.
    • Use a single color for each section: e.g., blue for solid, green for liquid, and yellow for gas.
  • Label each section at the top: “Solid,” “Liquid,” and “Gas.”

Solid Section:

  1. Prepare the Display:
    • Cut out a small cube from cardboard to represent a solid object.
    • Paint or cover the cube with color paper.
    • Optionally, use cotton balls or sponges to add texture and represent other solid materials.
  2. Assemble:
    • Glue the solid objects firmly in place within the first section.
    • Add a label or description about solids, mentioning their fixed shape and volume.

Liquid Section:

  1. Prepare the Display:
    • Use a small transparent container or plastic cup to represent a liquid.
    • Fill the container with colored water (using food coloring) to make it more visible.
    • Alternatively, use a piece of blue cellophane or plastic to represent a liquid surface.
  2. Assemble:
    • Place the container or cellophane within the middle section.
    • Secure it with tape or glue to prevent it from moving.
    • Add a label or description about liquids, mentioning their fixed volume but adaptable shape.

Gas Section:

  1. Prepare the Display:
    • Use transparent plastic or cellophane to create a representation of gas particles.
    • Cut small pieces of plastic and attach them to strings to suspend them in the air.
  2. Assemble:
    • Attach the strings to the top of the third section, allowing the plastic pieces to hang and move freely.
    • Add a label or description about gases, mentioning their adaptable shape and volume.

Final Touches:

  • Use markers or paint to add any final details and descriptions.
  • Ensure all components are securely attached and the model is stable.
  • Optionally, add arrows or diagrams to show how particles are arranged in each state of matter.


This working model visually and effectively demonstrates the three states of matter, making it a great educational tool for explaining the properties of solids, liquids, and gases. Enjoy creating your project!
