Cats Rule, Students Drool

Today was a PD day.

This video has a fun and simple demonstration of the importance of fluid density in buoyancy and stratification. Fresh water (red) and salt water (blue) are released together into a small tank. Being lighter and less dense, the red water settles on top of the blue water, though some internal waves muddy their interface. After the water settles, a gate is placed between them once more and one side is thoroughly mixed to create a third fluid density (purple), which, when released, settles between the red and blue layers. In addition to displaying buoyancy, this demo does a great job of showing the internal waves that can occur within a fluid, especially one of varying density like the ocean.

This dog was unable to gaze at his beloved cat due to some menacing potted plants, but true love won in the end.

It’s been a Wednesday.

Some classes.

When I teach something really cool but the kids don’t care.

When students ask me if I’m staying after school on a non-tutoring day.

Some people just don’t get it.

When I dilly dally at the copier instead of making my way to class. Always with the questions.
