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. What will happen to the water level of the pool if you throw the rocks over the side? Will the water level rise, fall, or stay exactly the same? 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:
- What if I empty a 55 gallon drum of water over the side?
- What if a prohibitionist empties a barrel of whisky over the side?
- What if I drop a cubic meter of ice over the side?
- What if the polar ice caps really do melt because of global warming? How will that effect the sea level?
