Apple Quarantine has to be removed from the Mac version before it will run. The subject to be dissected is viewed in 3D and students have the ability to manipulate the subject prior to dissection.įroguts has been made available by The Science Bank for PCs and Macs running Flash Player.
Each system is completely discussed and the correct order of dissection is ensured. The in-person students will label the frog on paper, though I do provide.
In both version, students will label a full image of a frog, though with slides, this was converted to a drag and drop version. Students usually work in pairs or groups of three.
I use this handout with directions for students to learn about the structures found on the frog and how to cut it. Students use virtual dissection tools i.e. Students in class will still be able to dissect a real frog specimen, though they will have the option to do the virtual version. Froguts allows users to virtually dissect a bullfrog, a cow eye, a starfish, a foetal pig, and owl pellet, as well as being able to explore a Mendelian Pea experiment and observe fruit flies.Įvery dissection is detailed and offers quizzes after each section. Froguts is a virtual dissection tool for school and home learners.
