While wall and notice board decorations help brighten up the institutional look of classrooms, they can also be quite useful as visual aids to incorporate into lesson plans. Decorations depicting the sea can be used to display various species when studying marine life. Aside from lesson plans, ocean decorations can be used to welcome students to a new year or as a birthday reminder board.

Skill level:

Things you need

  • White butcher paper
  • Blue cellophane
  • Sea creature stencils (including fish, shells, octopus, starfish, etc.)
  • Pencil
  • Package of multicoloured construction paper

  1. 1

    Cover a notice board with a layer of white butcher paper, then a layer of blue cellophane to represent the water. If creating a wall decoration without a notice board, create the entire decoration on a large piece of cardboard and suspend it on a wall once completed.

  2. 2

    Trace the sea creature stencils on pieces of construction paper, using orange for starfish, purple for octopuses and a variety of colours for the various fish stencils.

  3. 3

    Cut out the sea creatures from the construction paper using the scissors. Add decorative elements, such as eyes, fins and shading to the sea creatures using the coloured markers. If creating a birthday reminder board, write the name of each student and their birth date in the centre of a fish using the coloured markers.

  4. 4

    Create an ocean floor by cutting sheets of yellow construction paper in half using the scissors. Cut a slightly wavy and variable line rather than a straight one for a more realistic look. Coat the construction paper with a layer of craft glue that has been thinned with the addition of water. Sprinkle sand from the cup over the glue before it dries to add texture to the faux ocean floor.

  5. 5

    Cut organic shapes that resemble rocks, coral and seaweed out of construction paper. Use photos of underwater ocean life as a reference.

  6. 6

    Attach the sea creatures, ocean floor, rocks, coral and seaweed to the notice board or the cardboard wall decoration using the stapler. Layer the coral, rocks, seaweed, ocean floor and sea creatures to give the decoration added depth.

Tips and warnings

  • Use white butcher paper below the blue cellophane to add vibrancy to the colour. Cellophane alone on a brown notice board or cardboard will turn a darker, greenish colour.
