Frog specimens are ordered from biology supply companies, or can be ordered from Amazon: Nasco Grass Frogs and students spend about 3 days on the dissection: 1 day for the external anatomy, 1 day for the digestive, and then a third day where students can optionally remove the brain and leg bones. The optional third day allows for students to catch up or make up any of the required activities from day 1 and 2.
The linked photo album shows all of the structures that are visible during a frog dissection, such as the liver, gall bladder, stomach, intestine, spleen, eggs. Most of the photos have two versions, a labeled version and an unlabeled one which can be useful for quizzing students. Some of these photos were used to create a a Quizlet: Frog Anatomy to help students prepare for the frog practical.
