Frog anatomy

The dissection of frogs is still happening in high schools all over the country, apparently. Poor frogs!

Here are some links so you can study their anatomy without actually poking through their guts.

Animated animal cell mitosis

Mitosis, that process of cell division that results in new cells, is taught in second-year biology. (It still is, right?) The whole process goes through various phases, which textbooks often illustrate.

Wouldn't it be great if it were animated, though?

Cellsalive.com has it -- animal cell mitosis, the animated version. Clicking on a "phase" shows you a still image of that phase, so you can move back and forth to see the differences.

Some lessons really do need something more than textbook illustrations to be effective. With a process like mitosis, for example, it's better to see just how one phase flows into another. You could imagine it, but not everyone has that vivid an imagination.
