Day 12

Context

We now have a fair amount of experience with density. Today we will engage in one last activity and wrap up the density discussion.

Explanation

We will look at how a floating dropper behaves in a closed container.

After this class you should be able to:

• Explain why the dropper sinks.

Model

Here are two pictures. The first one has the dropper floating at the top. In our demo this is the condition while the bell is not ringing. The second one shows the dropper sunk at the bottom. This is the condition when the bell is ringing.

Why does the dropper sink?
