The last month in the AP Biology class I teach has a number of projects following the AP exam. This year my students did a series of dissections.
First the frog….
The frog that was dissected.
Then the lizard …
The lizard is dissected by the students to show the internal organs.
And finally the squirrel (sorry Mr. Noren – we used it before it got too much freezer burn)
They worked to identify all the organs.
While dissecting the squirrel we discovered it was a female and she was pregnant, so 18 months after she had died, we dissected out the fetus
The unknown organ found - was the uterus.
The fetus was well developed and the careful clearing of the membranes left a well defined specimen.
As you can see they did a great job at the dissections. Well done AP Biology class of 2010-11!
The extra creature - a worm living in the frog.
And you even got an extra!!! The worm inside the frog’s mouth.
