Thinking About Sinking

We're studying water in my Dunn Middle School Science class, beginning with this classic stumper. Your boat is floating in a small pool with a load of heavy rocks.

Suppose the boat develops a leak and starts to slowly sink. How will the water level change as your boat takes on water and finally sinks to the bottom? Be careful, these are stumpers! Think first, but with summer still upon us, a wet experiment is called for!
Here are a few bonus stumpers:
