Coral food chain mobile

This activity is a fun way of learning about the different living things in the coral reef and how they are connected. This food web activity introduces young people to a range of animals that they may come across during a coral expedition.

Ages 6+

(adult supervision)

30 minutes

In this activity you will create a series of food chains connecting the different creatures that live on the coral reef. This will show how life in the ocean is connected.

Activity steps

  1. Download and neatly colour in the pictures of the animals on the coral life cards (see ‘What you’ll need' section).
  2. Stick the coral life card sheet to the piece of cardboard.
  3. Carefully cut out each of the cards.
  4. On the back of each card, write the name of the living thing and a short description. Use the information in the coral life gallery to help you linked from the 'What you'll need' section.
  5. Use the template for the coral food chain mobile to help you lay out your cards and lengths of dowelling or twigs, before you attach them together with string. An adult may wish to check over the order and placement before the different cards and sections are taped together.
  6. Once you are sure you have the right order, you can use the tape to stick lengths of string to each card and then to the pieces of dowelling or twigs.
  7. Once completed don’t forget to stick a piece of string to the sun, so you can hang your coral mobile up at home.

More ideas

If the whole mobile is too complicated an idea to start with, consider making a single food chain first. Start by placing a ‘producer’ on a table. Search through all the other cards to find a consumer that eats that producer. You might have started with seagrass coral and then found the green turtle that eats the seagrass. See if you can make the chain longer by finding an animal that eats green turtle, and so on.

If you are unsure about the science definitions, see the 'Find out more' section, and for the different living things in the coral reef, see the coral life gallery.

Safety guidance

  • This activity involves cutting out cardboard pieces, using glue and handling pieces of dowelling or twigs.
  • Cutting with scissors should be done using child-friendly scissors and under adult supervision.
  • If using wooden skewers as the wooden sections of the mobile, sharp ends should be cut off.
  • Care should also be taken handling the dowelling or twigs, and these sections should be laid on a flat surface or table as the mobile is being constructed.
