There are 2 really great websites already prepared for instructions on the fetal pig lab.
Because I have a small class, each pair of students actually has their own pig to work with.
This site, from Whitman College, is really comprehensive with pictures and details about each system and the different structures.
This site, by Mr. Dougherty at Penncrest High School, has great use of vocabulary terms, simple instructions, and expandable photos to help students understand the dissection steps. However, in following these steps, you will likely have students lose some structures (the cavity membranes and abdominal muscles) that are carefully preserved in the Whitman Site. I like this one slightly better (despite lacking some details that the Whitman site has), because the whole lab is on one page, you do not have to keep scrolling through to get through each organ system.
