Sept. 18 - Particle Theory and States of Matter

Here are the solutions to the previous homework: Density Problems - Solutions.

In particular we talked about number 11, which is how submarines float and sink.  Can we apply the same idea to help flip this boat?

This ship is called the Costa Concordia.  It's bigger than the Titanic, the size of a huge skyscraper, but when it got too close to the shore, it ended up on its side.

We discussed how they attached containers to one side of the boat and filled it with water to make that side sink while the other side floated up.  Here's a video of the whole process:

Here's a description of what they did:

It was a great feat of engineering and science to get this boat back upright.

This concludes our discussion of Density.  Tomorrow we will do the first lab to measure the density of a liquid.  There will be a quiz on density on Tuesday.
