Why dissect a frog?Purchasing the Guide

Middle and high school science teachers, are you hesitant to incorporate (or continue using) a frog dissection unit? Do any of the following statements reflect your feelings?

"Iím not really that comfortable with the dissecting steps and anatomical parts and functions!"

"Itís just too exhausting an activity -- so many detailed steps to describe and supervise!"

"Itís too tough to keep all of the students happy. Some students are rarin' to move on, while others need constant guidance!"

"Iím not sure the students even make the connections between the frog and the human!"

Iím betting that my guide will change your feelings about this very powerful unit. The steps are so detailed and the illustrations so clear that students - working in small teams - will enjoy teaching themselves. The connections between the frog and the human anatomy and physiology are continually pointed out. YOUR time will be spent hearing students "ooh and aaah" (and "ugh" a few times) - and enjoying guiding individuals.

I'm in my 39th year of teaching Life Science to middle school students - and still consider the frog dissection as one of my favorites. Over 20 years ago I decided that walking entire classes through this activity - step by step - was just too exhausting, so I put the first version of this self-paced guide on paper. This "final version" is the result of years of noting the stumbling blocks and revising the instructions.

In summer of 2005 I decided that the weakest link was the illustrations I'd been using, so I produced my own drawings. Convinced that my efforts would be of use to others (and to try to help me address some unexpected family medical expenses) I copyrighted my work and began licensing my guide to other teachers. I am happy to report that the feedback from purchasers has been overwhelmingly positive.

Over the last six years I've revised the guide three times, most recently in the spring of 2017, based on my annual observations of students' work. I've also added several suggestions based on my discovery of the significant advantages of bullfrogs over grass frogs. (See "Bullfrogs Recommended".)

I think you'll be impressed with the level of detail – forty-three 8½×11 sheets of text and fourteen sheets of large frog illustrations! Your students will be able to read and follow the exact steps for each stage of dissection. Along the way theyíll learn about the anatomy and physiology of the key frog organs and the corresponding human organs. For easier reading, the text pages consist primarily of short paragraphs which are separated by blank lines. For a small number of the more challenging terms I created a "pronunciation guide" after the word: i.e. cloaca (klo ā´kuh).

Youíll note that my frog illustrations (and their labels) are BIG. I created these after years of dealing with difficult to interpret diagrams from other sources.

Whether you are a veteran life science teacher looking to get more out of the frog dissection activity, a new teacher looking to manage your workload while inspiring your students, or someone teaching outside your area of expertise and perhaps needing a bit of help yourself, I'm confident you'll find "Keith Wilhelmi's Self-Paced Frog Dissection Guide" to be well worth the money!
