    Make a Sea Diorama

  1. 1

    Choose your format. Use a shoe box for a simple background. Not only are shoeboxes easy to find, but they come with a lid to protect your creation. Another option is to use foam board or wood to create a large platform base, and then add a background using another sheet of foam board or another piece of wood (attaching them together in an "L" shape). The advantage of this is that you can customise the shape and size; the disadvantage is you will have to purchase extra supplies.

  2. 2

    Create your background, the ocean water, out of a mixture of blue paint and school glue. This will give it a shiny finish to resemble water. Mix a few hues of blue and green in different spots to represent the changing colours of the ocean.

  3. 3

    Build the ocean floor. Paint the bottom in a sandy colour, then let dry. Spread a mixture of water and glue there using a paint brush, and sprinkle with sand to coat it. Shake the excess over a trash can gently, and let dry completely before continuing with your project.

  4. 4

    Add in wildlife. Use toy figures of fish and sea creatures for an easy option; glue them onto the background and base as needed. If you don't have figures, sculpt them from modelling clay or cut them out of paper. As another option, stick your figures onto small dowel rods and mount them into the base of your diorama so they appear to "float" in the ocean.

  5. 5

    Insert the plant life. Make coral and algae out of chenille craft stems; bend the stems and glue or poke them into the base and background. If you don't have chenille stems, paint or paper can be used to create these effects.
