Just in my opinion with kids ages 8 and 5, I would go to the turtle farm in the Caymans - they will just awwww over all the turtles! In Cozumel I would head over to chankaubab (however I have not been there since the hurricane) because they have dolphins, sea lions, snorkeling, and just an all around good time for a 10.00 admission fee (unless it went up). In Jamaica -- don't go out on your own - go on an excursion - perhaps dunns falls they may enjoy! Enjoy!!!
look into doing an excursion with the stingrays in Grand Caymen. Its a great excursion for the family,i would recommend using Captain Marvin.
I am not sure of the age restrictions for Dunns River Falls, the older one might be able to climb the falls with you. I would also look into spending some time at Margueritaville, fun family place or you could book a day pass at one of the inclusive hotels for beach access.
Cozumel - Channunkaab Park - great place for the family to spend the day. There are lots of family friendly beaches to choose from also.
I took my kids - ages 5 and 6 - on the Grand Cayman stingray tour. Took first tour available since the rays all come in for breakfast. My little guy was a bit intimidated at first - last one to get out of the boat and into the water - and he was the LAST one back in the boat. They loved it!

With little ones, in Jamaica I would consider the Rose Hall Beach Tour, plenty of sand and sun with lots to do. You could make a run to Margaritaville by taxi. If you dock in Montego Bay, the ride to the falls is long.
Grand Cayman---Stingray City...you've gotta do it at least once. Then go back to the village for some shopping and don't forget the rum cake.
Cozumel---everything everyone has suggested would be great for your kids. We did some shopping here too!
My baby is 18, so we will be zip lining in Jamaica with a trip to Margaritaville. Scuba in Grand Cayman (and buy rum cake). Dolphin Encounter (the one where you swim with the dolphins) or scuba in Cozumel, with a run to the beach, Carlos and Charlies and I have to pick up some vanilla in Cozumel.
If you are going to walk on thin ice, you may as well dance!
agree with Luanne that the White River rafting is very appropriate for the kids; you can get a raft for you and the youngest and intertubes for the older ones; don't book the excursion with the lunch included, it is extra and just another buffett; eat lunch at Margaritaville or back on the boat. If you chose to eat at Margaritavile; ask the driver to drop you off at the entrance to the complex the restaurant is located in. There is a pool slide at Margaritaville and some beach activities nearby as well.
Grand Cayman: stingray city is a must and there may even be time left over the the turtles
