We did some more work with measuring this morning. We laid down some tape in the lengths of all members of the family and some animals and prehistoric creatures. We had to solve a problem when one prehistoric animal was estimated to be 20 ft and our measuring tape only went to 16 ft!
There was some huffing and puffing over the effort involved at thinking outside of the box a bit. This technique was appreciated later at the aquarium when we were able to guesstimate how big some of the river giants were.

The aquarium was nearly empty and we got to hear lots of great information from the volunteer docents. We saw the seahorses getting their food which was pretty fun to watch.
A question that will require some research: how long can turtles stay underwater?
