Fold a fish and a whale, then give them a sea to explore. Choose colors, draw bubbles and seaweed, and build a paper aquarium with your child.
A paper aquarium craft example
Place the whale first and leave space for fish to swim. Bubbles and seaweed are drawn on the background.
These images illustrate craft ideas. Actual results may vary. Lay your actual folded pieces on the backing sheet before attaching them.
What to prepare
Square origami paper, blue backing paper, colored pencils or pens, and optional glue or double-sided tape. A3 gives several animals room; use fewer pieces on A4 or join two sheets. No cutting or gluing is needed for the folding steps. If the paper animals feel crowded, enlarge the background instead of forcing smaller folds.
Start with a 15 cm square and place the finished animal on your backing sheet. Try a 7.5 cm square for smaller fish, helping with small folds. Halving the paper side roughly halves the width and height of the same folded model.
Draw the background and arrange
Draw a seabed and seaweed on blue paper. Leave swimming space and room for bubbles. Position the whale first, then arrange fish in the remaining space.
Attach or keep them movable
For a display, use a little glue or double-sided tape on flat areas of the back without crushing tails or folds. For stories, leave the animals loose so they can swim to new places.
Tell stories in your finished aquarium
Name them and choose a destination
Name each animal and decide where it is going. Take a role each and travel through the seaweed forest or along a trail of bubbles.
Find matching friends
Group fish by color or size. Arrange them from large to small, or let them swim in pairs. A new arrangement makes a new game.
Be an aquarium guide
Add name labels and introduce the animals to a visitor. If writing is tricky, an adult can write the words while your child adds pictures or patterns.
