I search (more like scour the web into the wee hours of the morning) for hands-on activities to help "lock" the learning in through experience. I found many great activities to do with the children related to our ocean theme in August at: Sea World Classroom Activities.
The boys LOVED the "Baby Shamu Suit"! They were able to identify the dorsal fin, as well as the fluke. It was also lunch time and what do killer whales eat? Fish! So we made grilled cheese sandwiches and cut them out with our fish shaped cookie cutter. I have never seen the boys eat their sandwiches so fast!
Here are a few pictures of them enjoying their "fish".
