Divers cannot talk underwater. The best way for them to communicate is by using hand signals or 'Dive Signs'. See how many dive signs you can recognise using this quiz.
Take the quiz to test your knowledge on underwater dive signs - the way that divers communicate underwater. Then have a look at some of the other activities to see how you can improve your coral knowledge or teach a full lesson about this topic.
To learn more about diving and dive signs, why not explore our Dive Signs Game or try our Animal Dive Signs Game.
To develop learning further try some of the full lessons on Coral Oceans. There are lessons for all ages 7 to 16. Science learning is covered with units for Coral Oceans 7-11, Coral Oceans 11-14 and Coral Oceans 14-16 units of work. Older students, can also benefit from our specialised Coral Oceans Geography 14-16 unit of work.
